- I have a Phoenix and have >300 flights on it. It is indeed a
- very well designed airplane. It has a speed range of ~20-160 mph.
- It will thermal and handles very nicely at low speed. Mine shows
- no tendency to tip stall and will fly "nose-high" when I want it
- to really slow down. When it does stall it does so gently and
- predictably. Though I am no aerobatic expert, it will do
- any maneuver you can do without an engine. All the reviews I have
- read say the handling is outstanding - and I agree.

- It is interesting that you can buy the F reloads for the Phoenix for
- the same or even a little less than the D disposable for the AB. And
- it goes *a lot* higher. I've flown the AB and tracked flights on both
- rocket gliders (RGs) A light AB will get about 250 ft on a D for a
- flight of ~45 sec. A Phoenix will get about 400-500 ft on a F for a
- flight of ~3 min in dead air. A Phoenix with a G reload will get ~1000
- ft on launch for a flight of 6-8 min. The Phoenix can be thermalled
- *up*. The AB can be thermaled, but only for a reduced descent rate.
- It won't climb in a thermal.

- You can do that, or, do what I do. Fly the Phoenix off a high-start.
- I get ~300 ft with a standard high-start. Flys like a champ. Rock
- steady going up.
-
- The other excellent option is to fly the Phoenix on a slope. I wish
- there were a good slope near me. It will scream in a dive!
-
- If you want the *ultimate* knee-knocking thrill buy an AeroTech F25
- disposable motor and fly your Phoenix. It will accellerate from
- 0 to ~160mph in about 2.5 sec. Has about a 2 foot white flame. You
- won't be able to wipe the grin off your face for a couple of hours.
- BTW, if you do this, be sure the Phoenix is trimmed to boost without
- input from the pilot. No glitches allowed!! Also, make sure you build
- it per the plans.
-
- One final note, AeroTech is coming out with some disposable motors
- specifically designed for the P while waiting for the DOT thing to
- get resolved.
-
- Have fun! It's addictive.
