The 3 channel ones with counter-rotating blades are inherently stable.

The 4/5 channel ones have full cyclic and collective control, plus tail rotor control. It takes a while to confidently hover one, but learning on a simulator and then training undercarriage means this can usually be accomplished without crashing.

Unfortunately, crashing almost inevitably involves damage with a bigger chopper - much more mass and inertia of the moving parts.

The gyro on the bigger choppers is only for stabilising the tail, it has no effect on the cyclic control.
