The .25 FX has enough power to fly a Tower Trainer 40... (not very aerobatic... but it will fly just fine.) That engine has more power than some of the cheaper .40 ci engines.
I'm actually thinking of putting my 25FX on my old Superstar 40 trainer. Think it would work. I understand it would not be very acrobatic, but I just want it to be able to fly and do taouch and goes without too much trouble and maybe be able to handle a little wind on landings.
Caution... if you get an instructor that doesn't know how to "fly the wing" instead of "point the engine" the low end of the recommended range engine will give HIM problems.
Someone that understands power management can do fine. Someone who has become dependant on excessively abundant power wold be in trouble.
Its a different style of flying than what you see at most fields.
