Avios Sea Fury. Unofficial Unboxing.

...my first retracts

The Sea Fury is the first Avios product I've sampled and it seems like a nice-quality kit - very neat EPO moulding, good paintwork and nice decal application.

The Sea Fury also features a neat magnetically-operated drop mechanism for the drop tanks - a rotating magnet attached to a servo which reacts with the magnets embedded in the drop tank mount. This is a very neat arrangement and which seems to work well in static mode at least.



The Sea Fury features dual split flaps, another first for me, and which looks to give a nice lift-boost for landing and perhaps take-off. And I'm thinking the Sea Fury is going to need it, with a take-off weight north of 2kg!

Another thing that concerns me a bit, although nothing specific to Avios, is whether the retracts will stand the test of time. Retracts in foam models seem to be a liability, and my runway is only sports-field grass. so we'll have to see...

Radjet 800. First Flight.

...back better than ever

The arrival of the Radjet, my second and a replacement for the much loved and even more battered original, was much anticipated. The pretty original had been the subject of countless crashes as I struggled to learn the secret of getting it into the sky.

Along the way I learned about the delicate balance required with speedsters, and not to get the Radjet into flat spins form which it struggles to escape. I also learned, and relished in, the Radjet's capacity for rock-solid performance and high-speed stability.


My arrival of MkII caused some angst as nearly a year had elapsed since it's predecessor had retired after the incident with the sapling. Fortunately, and remarkably, my lessons learned were so entrenched that the pretty speedster launched and flew virtually perfectly.

Something that I never had the opportunity to appreciated before it was pummeled through launch training, was just was cleanly the Radjet flies, swift cruise at half throttle and effortless acceleration out of dives.

So, despite the nervous anticipation, the Radjet is back and reinforces my perception that this must be one of the best-value foam speedsters around...

Radjet 800 Unboxing

...what's in the box

The Radjet comes nicely poackaged - double-boxed with all items individually wrapped in plastic, so there's no damage.

The parts are nice-quality EPO, and the kit also includes an underside protector skid. The canopy is a loose moulded plastic part which needs to be attached to the base, which includes magnets for attachment.


This kit, the PNF, includes a pre-installed 1850kv motor, and a 20A speed controller, good for 100-120kph performance with a 4S battery.

All parts fit neatly together, with the tail & wings needing to be glued. Note that you'll have to add some sort of reinforcement to the wing joins, preferable some sort of spars or strips because the basic joint isn't going to cope with the wing loadings of this pretty speedster...

Rarebear Funfighter. First Flight.

back in business...

The Rarebear was my second fast plane, after the notoriously hard to launch Radjet. Despite its diminutive caricature proportions, it was blindingly fast and flew on rails. However, as happens, it had it’s share of incidents, including a near lipo fire and a high speed excursion through a barbed wire fence. Finally, battered and weakened beyond stable flight, it was retired to the wall and gradually stripped of it’s internals for new projects.

So it was with great excitement that I came again to consider another Rarebear to join the flying corp. The first time round I’d chosen the PNF version, in the rather dull white and brown livery, but this time I got the ARF kit, unpainted and without decals. This time also I changed the battery; last time I went with the “ballistic upgrade” 45-90C which, when combined with the diminutive current-junkie funfighter motor, makes for epic speed and addictive noise. However it was far too fast in reality, so this time I chose the same 850mAh 4S battery, but in more sedate 25-50C form.




Also, I had a bit of fun rendering the Rarebear into its donor Bearcat regalia; Navy decals with pacific blue paint (a few shades lighter than the real thing). Overall I thought it looked great. Also, importantly, I applied tape to all the hinge lines (excluding the rudder which doesn’t function) to avoid a repeat of the “missing bits” episode of the original.

So to the first flight. Yes, I was nervous. The Rarebear is small, fast and can kick on launch, so certainly not to be taken lightly. So it was with some trepidation that I threw it up on about half throttle and held my breath.

As it turns out, the rare bear was very well behaved, climbing sweetly into the sky; a little steeply because I’d set the elevator up a bit and, after it had levelled off, flew absolutely beautifully, straight and stable, turning with characteristic crispness and climbing with absolute disregard for gravitational dynamics.


In all, the first flight was excellent, the little ‘bear even slowing up for landing without a hint of wing drop, so I’m now looking forward eagerly to pushing the limits towards full throttle, enjoying the subdued howl of the little fighter across the kangaroo paddocks…

Fox Glider with Funfighter Motor.

...back with avengeance

The little Fox glider is a beautiful flier, however mine has always suffered from motor vibration. Even the addition of a supplementary firewall didn't make much difference, so the little Fox was eventually consigned to hang on the wall whilst I decided what to do.




Help came in the form of the forced retirement of the Radjet, and I transplanted the Funfighter motor I'd installed there into the Fox. To complement this I'm using a 1500 4S Zippy compact battery, lightweight enough not to tax the speedy motor but large enough to provide generous flight times for the sleek Fox.

The result is speedy, the slippery Fox now genuinely fast and very quiet, the Funfighter motor providing it with landscape-traversing speed and generous, although not unlimited, vertical climb.

So all in all a simple and very successful transplant, the Fox glider flying with the Radjet's heart...

Stinger 64 EDF. Repair Flight.

...back in the air!

It was months ago when, having too much fun with the Stinger, I inadvertently sent it speeding into the swampy paddock grass, where it half its nose and my near-new nanotech battery disappeared into the mud.

Since then I have agonised over how I was to replicate the tapering form of the nose, which also accommodates the canopy magnet and terminates into the join with the nosecone.



Eventually I used rear sections of the original fuselage (funny how you never crash backwards), although this wasn't quite right and had to be cut, and then added onto, and then filled, and sanded, and painted.

However, after this unnecessarily protracted affair, the Stinger was again airworthy and looking pretty good. However, the proof of the pudding if in how well it flies.

Fortunately, in this case, it flew as well as ever, and I was gifted with a good launch as well. So back to enjoying a few run-filled, adrenalin rushing minutes screeching the Stinger around the paddocks...

GeeBee R3. Flying Around.

...having some fun

The little GeeBee is kind-of strange to fly, as I may have said before - it appears to be dragged around by its engine and has the very characteristic forward-jutting undercarriage.

However, despite odd characteristics, it does fly quite sweetly, although don't fly it too slow or you'll have it upside down in the grass from a tip stall


One thing it does for you, almost without trying too hard, it knife edge. Maybe not exactly perfectly, however very stable and most entertainingly.

So, while I was buzzing it around, I put it into increasingly steep turns and had it knife-edging around for my amusement.

A fun little plane, except when you try and land it on grass...

Stinger 64 EDF. High Speed Crash.

...best of times, worst of times

 A beautiful sunny afternoon with a gentle southerly blowing set the scene for some great flying with the Stinger.

Now, with its third iteration of decals, it sported much improved visibility which boosted confidence in flying at speed. Picking its orientation, primarily roll, had always been a bugbear with me, but now I was able to fly it with much greater authority.


For once the launch was good and the Stinger was soon howling round the paddocks, executing thrilling low passes and high turns.

This was the best I'd ever flown it, by a long way, and the enjoyment of flying the speedy little jet and the beautiful setting was quite intoxicating.

Unfortunately this wasn't to last, with one low pass having me turn into the sun where, like previously, I mistook the orientation and the Stinger skewed into the marshy grass at speed.

Worse still, half of the nose had been blasted into the mud by the battery, with both embedded to the degree that they were lost despite my best efforts to find them...

Radjet 800 EPO. Paddock Flypasts

...fast fun


Breezy afternoons don’t suit too many planes; of mine the pick are the Rarebear, Stinger and Radjet. This particular afternoon there was a fresh northerly blowing and I headed right into the paddocks, my favourite spot for speedy planes free of any obstructions making it great for low-level, high-speed flypasts.



I find the
Radjet a very stable high-speed plane and able to handle wind with aplomb, so I had a great time speeding it upwind and downwind, always at full throttle as usual. Unfortunately, by the time I got to the fields this particular afternoon, the sky had got a little hazy causing glare.


As a result the video struggled a bit with the contrast and, although I tried to balance colours and lighting manually afterwards, it’s very difficult and the video still doesn’t look quite right.

Nevertheless, the flying is quite entertaining and the sky, although not as lovely as it had been earlier in the day, was still a lovely backdrop to the speeding
Radjet...

Hobbyking Stinger 64 EDF. Sunny Clouds.

...beautiful sunny clouds


Some days flying is really good, especially when the sky is doing something special. This was one of those days, with bright sun, brilliant blue sky and more kinds of interesting clouds than you could wish for.




It was pretty breezy; a moderate southerly which quickly developed, but nothing too much to bother the Stinger. With its augmented stripes I’m more confident with the turns, and having it screeching across the fields and soaring into the sky is always a lovely thing.

Watching the video again, with the beautiful sky and the Stinger having fun, was certainly a tonic for the rather miserable weather of late...


Canadair CL-415 1390mm. Flypasts

...cruising past

A pair of paragliders were heading back to the far field, so I headed the Canadair there with onboard camera, hoping to get some nice footage. Unfortunately I didn't judge the closing distance too well and turned the Canadair back when it was still well off, the paragliders unresolved dots in the distance.


For the rest of the time I just cruised the Canadair around doing flypasts, enjoying the lovely afternoon. After returning from its initial sortie, I took off the camera and then hand launched it to conserve the battery for a bit more cruising around.

The resulting video was then a little unexciting, so I decided to play around with it a little, adding in some flash-forwards and colour-to-mono fades. Completing this slightly experimental video was a backing track with a little attitude, dramatic hip-hop according to YouTube.

Anyway, I had enjoyed creating the video...

Rarebear 620 Funfighter. New Sodastream Cowling

...works a treat

For a while now the Rarebear’s cowling has looked a little sad, the missing sections of the flimsy plastic article having been poorly patched with fibre tape. So, needing to do a little work on the motor, I decided that enough was enough and dumped the cowling summarily.

As a replacement I first tried a large vitamin bottle which unfortunately turned out to be a little too small, before deciding in the base of a Sodastream bottle. This looked nice and sturdy, and had a little detail on it to add a little style.


It was slightly too big but I trimmed a section from it and then installed it with lashings of hot melt glue. Being careful to align the lower section, once installed I realised that I’d not checked the top which ended up slightly angled and pinching the sliding top section of the fuselage.

Anyway, it was still better than it was, so now to try it out. It turned out to be a very windy although otherwise beautiful afternoon, into which I threw the revamped Rarebear, newly reverted to its original black prop to match the cowling.

In short, the little rarebear flew just as well as ever, seemingly relishing the gusty conditions as it swooped across the field and swung rapidly into the blue sky...

GeeBee R3 750mm TRILOGY: PART 3: First Flight

...a few surprises

The GeeBee got its chance for a first flight on a beautiful, if somewhat breezy, afternoon with lovely clouds spread across a giant canvas of bright blue sky.

Playing it safe for the first take-off, I had the GeeBee on the dirt to give it a take-off smoother run. After a quick taxi-test, I headed it into the breeze and eased up the power.

It takes off pretty easily and without fuss, but the first surprise came when I eased off the elevator and found it nose-diving rapidly, so much so that I only just caught it in time. It was also turning right, so I had a tense minute or so as I steered it clear of trouble as I adjusted the trims.


After that things were a lot more enjoyable; it turns out that the GeeBee is very floaty, another surprise, and is fun and easy to fly. In fact its characteristics lead me to believe it has 3D capabilities, now I just need to develop mine!

It turns very quickly and easily and, with full power, is pretty brisk without being super-fast, so it didn't take long before I was flying it with some confidence.

Bringing it into land it floated in straight enough, rounding out well. I let it drop just a fraction, still a good landing, but this small jolt was enough to dislodge one side of the undercarriage and loosen the other mount.

However this is easily corrected with a little superglue, and I'm looking forward to exploring the GeeBee's abilities further...

GeeBee R3 750mm TRILOGY. PART 2: The Build

...so how does this work?

The GeeBee is a nice-quality kit, with solid EPO fuselage making it a smarter-looking proposition than a Rarebear, for example. While having a simple screw-together construction, it does however its construction poses a few questions.

How does the battery setup work, and where's the best spot for the receiver?

The first question is a puzzler, for me anyway having only had planes with unfettered access to the battery. Obviously, unless you're happy remove the wing every time you fly it, you need the ESC lead to remain in the battery hatch so it's accessible through the small hatch opening.


This I found achievable by mounting the ESC against the side of the fuselage, preventing the lead from falling back into the fuselage. This setup seems quite reliable, although packing the battery in and then feeding in the lead and connectors is still squeezy and awkward.

Regarding the receiver, in this case a twin-antenna Orange R615x, I mounted it in the central fuselage cavity which corresponds to a cavity in the wing moulding above. And, connecting all the servos from the back and the ESC from the front gives a very neat installation.

Next challenge is the bracing wire; five pairs of different length wires needing to be clipped into tiny hooks. Fifteen tediously fiddly minutes later I was finished.

The last trick was spinner and propellor. The latter simply gets tightened with a nut, with the spinner base in behind it. Then the spinner is installed; it comes with double-sided tape but, really, that's never going to hold. So I superglued it in place, with cardboard slipped in behind the base to keep it spaced off the cowling.

With everything in place the little GeeBee was looking good...

GeeBee R3 750mm TRILOGY. PART 1: Unofficial Unboxing

...a great-looking little plane

I’d had the GeeBee sitting in the corner for a while and finally got around to unboxing it.

It’s a nice quality kit, coming safely boxed and individually wrapped so that all parts were in perfect condition. The fuselage is even secured in place with velcro straps, a first for me.

The GeeBee comes in the classic Texaco livery which looks great and the decal application is nice. The fuselage is full EPO including the cowling which is nice, however there is a downside - the battery access is a small hatch on the underside.


The 5g servos, in wings and fuselage, are pre-installed along with the control horns. The high-standing tail wheel is also fitted, leaving only the tail planes to be screwed into place. The wing, with locating pins up front, is also screwed into place - a glue-free assembly.

The iconic GeeBee undercarriage comes pre-assembled, with integrated wire reinforcing which also serves as the mount slotting into the wing. Included is sprung bracing wires stabilising the undercarriage as well as bracing the wings to the fuselage, which should look great assembled.

The kit comes with two three-blade props and two spinners, the latter being the only disappointment - they're EPO, with the cone apparently needing to be stuck onto the base with double-sided tape! I'm not surprised to read that people have ditched these for real spinners. In fact, had I known, I’d have tried to get a replacement spinner when I ordered the kit…

Trainstar Tough Trainer 1400 EPO. D4023 Motor Test Flight.

...test flying the new motor

Fortune smiled this afternoon with the growing cloud cover holding up just enough for a scenically sunny afternoon for flying. Conditions were a little choppy but, given the lovely afternoon, we were going to give it a try anyway.

As well as being the test flight with its new motor, this was also the first time I’d flown the Trainstar for months after its collision with a light pole, so it was perhaps not surprising that it was out of trim.



As soon as it took off, it was evident that the Trainstar had become very floaty, in contrast to the nose-down attitude I’d been flying it previously. Nevertheless, it was still fun to have it back in the air.

After having a bit of fun floating it around, I brought it in to check trims, and then it was back in the air, flying a bit flatter than before. It was still not smooth flying though, with gusty conditions and wind shear above tree level turning the Trainstar into a kite of sorts.


The new motor performed very well, at least as powerful as the OE unit, and perhaps a little more. Considering its modest cost and ease of replacement, it’s a viable alternative to Volantex’s dodgy prop adapter…

Stinger Ready to Go

...hopefully it will be good

The Stinger has been reconstructed with its new fuselage and replacement fan unit, fitted with a zen-first R615X receiver  and, just yesterday, received its new Nanotech 2200 4S 45-90 power pack.

Apart from it looking sharp and new with the replacement fuselage, and interest in how the new DSMX receiver will work, it's the performance impact that the big nanotech will make that I'm most intrigued in.



And it is big; in fact it's too wide to fit easily into the fuselage, bulging the foam past the matching form of the canopy. I'm hoping that in due course the foam will compress a little to reduce this distortion but there's no denying that there's a lot of battery there.

My experience with 4S nano's on my Rarebear indicate that they offer substantial performance improvements, although I'm not sure whether, in this case, the additional grunt will be offset by the increase in mass over the 1800 40C Zippy I used previously.

Anyhow, I'm very interested to try out the reborn Stinger. I had, in fact, been hoping to get it out this afternoon for a test run but the weather wasn't cooperating with overcast and windy weather. Lets hope there's a mild and sunny afternoon in the offing soon...

747-4 Trainstar Shaft Adapter

...so I got a new motor instead

I ended up terminally bending the shaft adapter on my Trainstar some while a go as the result of colliding with a light pole. While, in the past, I have managed to straighten the adapter by hook or by crook, this time my efforts were in vain.

Now, it must be said, the Volantex (nee Lanyu) prop adapters are rubbish, a conclusion based on my experience of both the 
Trainstar and Phoenix planes, and I've heard this sentiment echoed by others as well; the adapter material is very soft and prone to both stripping and bending.

I've previously looked at the Volantex store but, despite having the items on display, it seemed impossible to actually buy anything. And I couldn't find anything on the web either. However reading through a thread about Volantex spares yesterday,  the website had apparently become functional.

My optimism at this news was unfortunately was short-lived as, while the prop adapter is there (and on sale!) 
an error came up when I tried to finalise Paypal payment and, despite repeating the checkout exercise, I still had no success. So I again abandoned Volantex for spares (why is it so hard?) and headed to Hobbyking.

The Volantex motor for the 
Trainstar is a 4023/850KV and fortunately Hobbyking have an exact equivalent, the D4023-850 Out Runner Motor. This, however, comes fitted with a steel prop shaft instead of the aluminium of the Volantex, and is also only about half the price.

So, while I really didn't want to buy another motor when all I needed was a prop adapter, it all got too hard...

Stormclouds and Rarebear

...lovely contrast

The weather this morning wasn't great, with imminent drizzle threatening to cut short any attempt at flying and overnight rain meaning wet shoes would be guaranteed for my efforts.

The afternoon was, however, somewhat better so I headed to the field with the DC-3 and the Rarebear. I punted the docile Dakota around for a while and then, feeling like something a little more energetic, brought it in and got the little buzzy ready.

By this time heavy storm clouds had rolled in, providing a lovely contrast to the few adjacent patches of blue and, of course, the little white form of the Rarebear. Being quite picturesque, I landed it and dashed off to the car to get the Mobius.

Now, low light conditions aren't the Mobius' strong point, but I hope that the footage will at least capture a little of the lovely variety of cloud textures and colours...

Hobbyking Radjet 800. Sunrise.

...high-speed fun

The other morning I took the Radjet along with me. I hadn't flown it for a while so the launch is always a slightly tense affair, but my launch technique is still solid, with the Radjet launching into the growing sunrise. 


It's still pretty quick, although slightly off the pace when it was flying the little 850mAh nanotech, however it's quick, and stable enough that you can bring it over on super-low flypasts with confidence.

It was a most enjoyable flight and, as the battery died off, I turned the Radjet around for finals. The Radjet is surprisingly easy to land; with power off it is pretty floaty, and it glides in surprisingly easily.

Except this time when I had it headed into the tree behind me...
