I would absolutely steer clear of a .60 two stroke on this plane, it is way to heavy and a short blip of full throttle in a strait line would most likely shed the tail and ailerons and so forth before you had a chance to react.
I have a TT61pro on this plane and it is fine it may be alittle heavy but not too bad. not sure where im ballenced but no weight was added anywhere.
it turns a 13x4w prop to 11800 RPM the 13x4 spooled a bit quicker but they didnt have any last time at the LHS.
I have HS422s on ailerons 425s on elevator and 635hb on rudder.
with this combo i get little over half throttle hover good pull out(not rocket, enough to inspire #9 violation) and the occasional accidental momentary full throttle down line has not yet produced flutter. (KNOCK ON BALSA)
i know im not being smart with the servos but i cant afford any better on this plane.
