Take-off Takeoff and 30% climb out at 1/3 throttle. It does consecutive inside and outside loops at 1/2 throttle.....really never needs full throttle. Throttle up to full and pull vertical and it just keeps going and going and going .....just awesome power
Flight behavior My attempts at hovering were "semi-successful" as the power to accomplish a hover is definitely there ....but the pilot skill is lacking. Well, at least I now have a combo that has the power to let me practice until I can do a hover.
I would highly recommend this power train to anyone considering converting the Diablotin Mini ARF to electric power. 
The Diablotin Mini with CG at the forward end and reduced control throws is actually easier to fly than anything I own. It flies slowly and lands at a very low speed. The beauty of it is that because of its slow gentle flying characteristics....

Other comments weight: 73 ounces, Futaba T6XAS Transmitter, FP- R127DF receiver, lots of exponential on Rudder, Ailerons and Elevator to smooth out flying around neutral but still give full throws on command. I also mix Ailerons and Elevator ( flaperons ) for very tight looping.

Take-off Take-off is easy, just power up and hold a little up elevator to prevent it from tilting forward. no more then 50% power is needed for a impressive takeoff.
Flight behavior Flies standard maneuver good, pretty slow roll rate. loops can be made very tight, approx 10ft or so. it knife edges, but it needs lots of pilot input ;)  Hovering is solid, it hovers with 80% aileron to hold against the torch. Torch rolling is also possible, with loads of patience and many hours practicing you can get this pale to do almost anything, I like it :)
Landing Landing is smooth too, just do a low approach and support with a little power, to make a soft touch down you need to land with the tail wheel first.

Other comments weight: 57oz/1620g, JR PCM 10X Air Transmitter, Schulze 835 receiver, 15% expo exponential to make it a little less nervous in level flight, but still have crisp response in hovering, I also mix Ailerons and Elevator ( flaperons ) for very tight loopings, approx 40%
