RE: scale flying with blade cp
watch it - too much pitch will bog the motor and stall the blades, which in the end means it falls out of the sky - too much weight will do the same, whether battery or body
the collective pitch head speed is so much higher - never put fp blades on a cp (been there done that), you'll fry the 4-in-1 - and the pitch on fp blades is like +10 degrees for a 0 degrees mount, so the pitch the cp adds makes them way too high and it stalls real bad - blows a lot of air, though - you could resort to this if you ever needed the cp to lift a hammer or something, but it'll probably kill the motor
the biggest problem with the hbk2 is the belt - sometimes it gets hung up under its own rollers and, well, its a belt, if the fan belt goes out on your car that's one thing, but the tail drive belt breaking in mid-air is a scary thought - i wish there was a redundant solution like two smaller belts running side by side or something like the r22
the falcon's shaft drive is neato, but i bet one good crash will knock it out of line forever and she'll shake like a belly dancer until it comes apart
also, if you, like me, have been used to the instant response of the cp's tail rotor, there's seemingly a slowness to the response of these tail-servo types - its not bad, but its there
heading hold gyro is useful when on a long final bucking a crosswind, but i have yet to use idle-up as it is meant to be used, although the collective coming up from the floor and the low throttle position being at the top sounds good, my thumbs remember low at the bottom a lot quicker - the dx7 supports flight mode 1 and 2 besides normal - llnacp and hwlf modes?
