I am flying mine w/ FPE 2.4 and it is a good choice. While it does not have unlimited vertical, It flies the quite nice. I am not a 3-D flyer, but do like aerobatics, and it will do all the scale manuevers nicely, and due to the lite weight of the engine, keeps the whole package much lighter. I have flown w/20x10 Zinger Pro, and also w/ 19x11N Mezjlik 3-blade. I like the 3-blade best, good down line braking. This plane does not have the traditonal drag that most bipes exhibit. At 15lbs, floats in on landing, and will overshoot very easy. Have about 25 flights on mine and think it a KEEPER.
