Compared to the Lambada when viewed from the outside, four things are readily apparent. The fuselage is very streamlined, the canopy hinges at the front, the wings have a new shape, they are mounted low on the fuselage and there are full span flaperons. The low wing means that you step up onto the wing from the rear and then have an easy step down into the cockpit. The cockpit tapers back on the aft fuselage much further, so there isn’t the long skinny tailboom like on the Lambada. Also, the Phoenix uses two levers for the spoilers and flaps so that they can be used independently. The wing extensions are twice as long as the Lambada’s, hence the no wingtip span is around 36 feet.



I headed for the end of the runway when I saw the Phoenix returning. There was a Lambda landing just ahead of the Phoenix, and I noticed a huge difference in wind noise between the two aircraft. The Phoenix has a light whistle to it much like a pure glider. It was a lot of fun watching the various angles of the Phoenix in the pattern, and I kept thinking, this is an awesome looking plane! After watching some boring landings it was my turn to hop in.
The first things you notice inside are the plush, black leather appointments, much like a luxury automobile. There are map pockets on the sides, and a large glove box on the panel. A stretched cockpit provides more leg and headroom than in the Lambada. For me, at six-one, it was nice to have a little more legroom. The center console which houses the flap, airbrake, and trim levers is very ergonomic, allowing easy access to these controls from both seats, and will allow an instructor to correct airbrake settings on final approach without excessive arm motions. These controls are far enough forward that the arm and elbow area is padded and comfortable. Just forward of the console on the floor is the tow release lever. The throttle, choke, and switches are positioned normally on the panel.
Starting the 100hp Rotax is straightforward. Throttle at idle, half choke if the engine is cold, no choke if the engine is warm. The Rotax cranks up immediately, as usual. With the forward hinged canopy, there are no worries about starting and taxiing with it open.
After securing the canopy, we advanced the throttle to full, and executed a no flap takeoff on the beautiful grass runway. We were off the ground in about 500 feet, even though the runway needed to be mowed, and climbed at 110kph, achieving 5m/s with two of us and half fuel. We climbed about 1000 meters, and then leveled off for cruise flight. 4700rpm resulted in a speed of 185kph. Slowing to 100kph, a few dutch rolls confirmed a roll authority slightly better than the aileron only Lambada. We shut down the engine and feathered the prop and using 0 degrees of flap we climbed at 2m/s. During the climb we intentionally slowed to the stall buffet (which is a little more pronounced than in the Lambada), and still had good aileron authority.
We headed for the next cloud about 4 miles away. Cruising at 95kph, the sink rate on the vario showed around 1m/s. When we hit the thermal, we again did not use the flaps initially, since I wanted to compare the flight characteristics with the Lambada. About the only change is the view out of the cockpit, with the low wing, and the out-of-sight cowling. Dropping the flaps 1 notch allowed us to slow the plane about 3-5kph with the same bank angle. The climb rate increased as is to be expected, and the roll authority remained good. There are two positive flap positions on the prototype, but this will be changed as explained later.
With the engine running again, we performed a full stall series with flaps up and down, and spoilers up and down, wings level and during turns, which all resulted in stable mushing stalls with no tendancies to spin, just like the Lambada.
Back into the pattern with a bunch of other aircraft, including a tow plane busy hauling gliders aloft, we entered downwind, and flew the approach without flaps. The spoilers rise higher out of the wing than the Lambada, and are more effective. Except for the different sight picture out of the cockpit, the landing went as expected. Full spoilers just before ground effect, and then just keep the plane flying until it touches down on three wheels. Full power, and we were off again in short order. The second landing was with full flaps (position 2 – about 20 degrees). The approach angle was a little steeper, but not much. But the flare angle of attack had a lower nose angle, meaning the mains touched first, then the tailwheel and I bounced it. Adding power, (I could almost hear Josef laughing), we went around for another go with flaps. Same result. OK, forget the flaps, in we came, and another nice 3 point landing. Conclusion; the Phoenix lands just like the Lambada without flaps, you could even call it autoland. Just pull back in the flare, and it lands three point. No special timing is required. But with flaps, the flare angle of attack is not a three point position, so it takes some special timing to pull it off. The second flap position isn’t really good for anything. A full spoiler approach with a slip is going to result in a higher sink rate than the flaps would produce. But one notch of flap is good for thermalling, and negative flap increases glide speed, so the final flap configuration will have this arrangement.
It was a warm day, and the canopy did not have opening side windows, so it got too hot in the cockpit. The vents will be reworked, and the canopy will have sliding windows as well, so that should help.
