Phoenix 2000. First Flight.

...a little slope soaring

I've chosen to set up the Phoenix 2000 as a pure soaring glider without motor, running a 2200 3S battery located right at the firewall and some small-change ballast installed in the nose cone.

I have configured the Phoenix with crow brakes, as I discovered that having some sort of brake/lift dump is essential, whether that be fence-type brakes or, in this case, flaps and ailerons configured to generate drag and reflex the airfoil respectively




There are, unfortunately, no good slope soaring sites nearby, however I decided to try the hill at the far end of the paddocks where I fly; not particularly high or steep but enough to generate a little lift.

The wind was a strong north-wester, a little gusty too, and I launched the Phoenix with as lusty a hurl as I could summons. The Phoenix flies well enough, catching what little and sporadic lift was available here.

I tried the Phoenix with and without flaperons active but, given the very turbulent conditions, I couldn't asses the effect they have.  Similarly, I didn't get the opportunity to really test the crow brakes, however they were effective in slowing the glider down and didn't cause it to climb when deployed which is good.

However, as a first try, the Phoenix is encouraging, so I'll be trying to get it flying in some better lift...

Phoenix 2000 EPO Composite Glider. Unofficial Unboxing.

...back to the future

The Phoenix 2000 was the very first RC plane I purchased, and so this is very much a back-to-the-future episode for me.

The Phoenix 2000 is, as it was back then, a very well build and affordable RC plane. It has a sturdy plastic moulded fuselage, which it shares with its sibling the Phoenix 1600, which comes complete with plywood battery tray and rear servo deck.

The fuselage comes with the rear control rods pre-installed and, on PNF versions, the servos installed and connected.



The wings are good-quality EPO with moulded-in reinforcements, and a carbon joiner rod is supplied as well. There's also a sleek moulded plastic canopy which clips onto the fuselage.

The wings have substantial ailerons, with servos installed on the PNF package, although control rods have to be fitted yourself. There's provision for flaps including moulded recess for servo and linkages included - you just need to cut the flap free where they're moulded to the wing.

The kit comes with a folding prop and spinner with collet adapter, and there's a fixed nosecone in case you just want this as a pure glider.

So the Phoenix 2000 comes highly recommended as a high-quality entry-level glider, sturdily constructed yet elegant and capable in the air...

Raptor at the Beach Again

...good wind & good lift

Today I returned to the beach again for the third time to slope soar the Raptor. While he wind direction and strength on the first two occasions was a little weak and misdirected, this time everything was good; 30-40kmh southwesterly coming straight onto the dunes.

In fact, walking down from one car park, the wind at the top was that brisk it had me wondering how I was actually going to get the Raptor down to the beach without it taking flight involuntarily.


Fortunately, I found another path that wandered down through the dune growth, providing a sheltered entry onto the beach. The Raptor prepped, I spun the prop up and waited a little hesitantly for a drop in the wind.

Hoisting the Raptor up, it climbed steeply before levelling it off and steering it onto the dunes. The lift was much stronger than before and, after a little trimming, got the Raptor floating motionless above the bank.

Not that it was as peaceful as it appeared; rather I was on high alert, making sure the Raptor didn’t drop a wing and get blown down. At some stages the Raptor, with flaps on, was actually drifting downwind so I was having to switch between flying clean and with flaps, and trimming the elevator up & down to suit as well.

So successful but not exactly peaceful! And then the landing; because my radio doesn’t have enough mixes to set up the ailerons as spoilers, I again had to zigzag the Raptor up and down the beach to loose height, before eventually nosing it in foe a sand-covered landing.

I really need to get another radio…

Raptor Glider D-Box Pro 2000. Hill Sloping.

...a beautiful afternoon with a view


Having managed some soaring at the seaside, I turned my attention to the nearest inland sloping spot; a set of ridges about half an hour’s drive away. These ridges provide lift in a variety of directions, but today it was blowing southerly. The location for southerly lift is a little tight on landing space and has trees about which makes things a little less relaxed, however I wasn't going to let that put me off.



I launched the Raptor into the strong southerly under power, just to be sure, and was soon getting reasonable lift. Some sections of the ridge were better than others, the far end seeming to be poor and the narrow clear section right in front providing the best lift.

Once I'd trimmed the Raptor to slow it down a little it was performing pretty well, until eventually the breeze ebbed away and I resorted to sending the Raptor on lazy missions away from the ridge over the picturesque farmlands until the battery ran low...

Raptor Glider 2000 D-Box Pro. Slope Soaring at the Beach.

...finally getting the Raptor sloping

Slope soaring is something I've wanted to do for a while but the lack of nearby locations has been a bit of a damper. However, I finally decided on an excursion to the beach, a well-rated spot for getting lift from the ocean breeze rising over the scrub-covered dunes.

The promised southerly wind unfortunately had an easterly component which meant less lift from the south easterly beachline, however I was determined to have a go anyway on the understanding that it wasn’t going to be ideal.



The most confronting feature doing this for the first time is, of course, the wind; I would normally never consider getting the Raptor out in this kind of wind and yet, here I was. This location flies from the beach, so I launched the raptor under power to make sure it didn't end up in the surf.

Climbing into the strong breeze, around 30km/h, the Raptor rose sharply. After getting a bit of a feel for the wind I eased the Raptor towards the dunes and some lift.

The other interesting thing is, of course, the wind; I had barely settled the Raptor in when I was dropping the flaps more and trimming it up to slow it down. And wishing the wind was a little stronger. And this is with a slow glider!

The sloping was challenging and fun, although the oblique wind angle meant I had to resort to occasional power-boosts to get the Raptor up again. Nevertheless, it was a good first try, a proof of concept…

Phoenix 1600 Soaring

...my first soaring flight!

This morning I had, rather unexpectedly, my first soaring flight with the Phoenix 1600 glider. Rather unexpected is as much as I had no expectation of there being lift about at that time, a leisurely nine o'clock departure due to sleepy disposition precluding getting out any earlier.


It was a lovely sunny morning following a clear cool night, although the breeze was already beginning to pick up from the East. I launched the Phoenix but saw immediately that it was turning to the left, an affliction which I have annoyingly been unable to eliminate satisfactorily, although twisting the left wing a little is a topical remedy.


Whilst bringing the Phoenix down for repairs, it was accosted by a very annoyed magpie flying down from its nest, the episode spurring me to mount the camera on the Phoenix to capture the antics. So it was, with the wing corrected and the camera running, that the glider powered up again into the blue morning sky.

Having previously tried to get the Phoenix in lift with only very moderate success, I was amazed to find that, once up a few hundred feet, that the glider didn't seem to be coming down in a hurry. Without having a variometer it was of course difficult to determine where the lift was, but flying over the road seemed to work well. The first run lasted a good few minutes before the Phoenix fell foul on sink and headed towards the field.

The next run was more successful, the glider staying up ten minutes, having to turn it back at one point as it climbed and drifted into the distance. Finally the breeze grew too strong, pushing the lift too far away...
