I just recently bought (from Peter Ayache @ Altecare RC) a turnkey Phoenix powered by a Behotec Hp66. The PHoenix was RTF with Behotec retracts and struts (the ones that trail behind).
I fly from rough grass, and needed a more sporty jet than my AV8R and Super Reaper - something clicked with the lines of the Phoenix with me.
ANyhow, as well as lookin nice, it is one fine flying plane! The HP66 (kero start) pushes it quite well and take off's are smooth and solid, almost like it wnats to lift off when its ready.
In the air, it flies very solid (and the 3 test flights I did were in high winds, about 30km/h). It flies smoothly but with full rates, is quite maneuverable. The engine can give you as much verticle as you want, especially when some fuel is burnt off.
Landing, well, I was not prepared the first few times for how slow this thing can actually get with full flaps (breaking two of the retract pins due to a too quick descent). Once I learned that you actually have to keep some power on during the landing, it flies in at a slow rate and is solid all the way down.
This is definitely the smoothest, most "fun" jet model I have flown and the Behotec turbine (my first) starts and runs very, very well. It is almost too quiet in the air!
I would definitely recommend this model to anyone, it flies easy enough for a trainer IMO but is sporty enough to really have some fun with.

PS now I need to finish off my Reaction 54
