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…

Raptor Glider D-Box Pro 2000. 5 Star Morning

...gentle flying on a beautiful morning

Winter mornings are often dull and overcast, sometimes with drizzle, mist or rain. However, on occasion, they deliver outstanding sunrises and, on this occasion, a five-star morning with mist, pretty clouds, sun, blue skies and no wind.

I haven't been flying in the mornings lately as sunrise around the solstice comes too late. However, having missed my alarm on this particular morning, I assed the field with sky alight with the sun about to rise.

With the Raptor on board this was like receiving a written invitation, so I headed to the field. The cold winter morning air makes the Raptor extra floaty, so that with flaps down it approaches so slowly as to appear in slow motion.

And, with no turbulence, one is able to make low passes and low turns in absolute confidence, adding to the tranquil mood of the morning...

Dynam DC-3 Dakota 1470mm. Spectacular Sunny Afternoon

...a pleasant sunny afternoon

Monday morning was grey and miserable but, just to be sure, I packed the DC-3 and Radjet. This was just as well because, by lunch time, the weather had cleared to a beautifully sunny and mild afternoon and I would have been most upset to have been flightless.

Happily I headed to the field with the afternoon winter sun flooding the fields with warm afternoon light as it began to dip towards the western horizon.

The DC-3 is a docile creature suited to slow flypasts and modest aerobatics, so I spent an enjoyable quarter of an hour doing just that. I managed a really nice touch and go as well as a fast flypast.

Being quite slow I have been pondering a few possibilities to see if it can be made a little speedier, but we'll keep those musings for another day...

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...

Canadair CL-415 1390mm. Scenic Outing at the Little Lake

...a bit more successful

Following on from my rather unsuccessful previous expedition to the lake, I returned a week later with the Canadair again for another attempt.
I find flying off water to be rather stressful, due mainly to the inconvenience of failure, namely having to the boat out to rescue the plane and then pack it all up again. As a consequence I am much more nervous and therefore tend to fly much worse than otherwise.

The Canadair is easy to fly and I can generally fly it off the grass, not dissimilar in nature to taking off from water, with little issue. The takeoffs on this occasion were, happily, more successful although most were still a little nervy and one, which didn't make it into the video, was absolutely awful.

One contributing factor is that you don't always get to stand near the plane like you do at the field, and as a result you are literally distanced. I probably should've just gone to the large lake where I could have launched from right next to the jetty. However the little lake looked so scenic with the clouds in the afternoon sun..

Raptor Glider D-Box Pro 2000. Afternoon Cruise.

...a pleasant afternoon out

Sunday afternoon turned out sunny and mild, a nice opportunity to take the Raptor for a leisurely cruise around the field. With the local venue busy, I headed for a field at which I'd previously considered flying but never got around to going there.

The field had had the grass cut back for some reason, leaving it with an interesting geometric finish, combined with its contrasting brown colour would make an excellent spot for a first FPV flight; you'd easily be able to find where home was!

Getting the Raptor out, I installed the Mobius atop the fuselage and sent the big glider soaring skywards. There northerly wind was quite mild but choppy, making the flight a little interesting when the Raptor approached ground level and curtailed most low and slow flying, which is can be the most fun.

Nevertheless it was a lovely afternoon to be out, and floating a slow glider around is likewise a suitably relaxing occupation. The most anxious bit was a brief inverted flight towards the end when, pushing the Raptor in an inverted pull-out, I realised there was insufficient charge in battery to execute this power-sapping manoeuvre.

Rolling the Raptor out, I pulled up steeply and came awkwardly close to a flood light pole, hitting which would definitely have ruined a lovely afternoon outing...

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...
