RE: wind and gyros
I use a digital JR servo on the one heli with the 401 - rock steady. I use the 401 with futaba "whatever it is" servo (is it 9234 - can't be ars8d to go and look) and is super too. I now have three 401s and love 'em but they do drink the battery juice and hate it when the battery is low. I just won't buy anything else except small GMS for indoor stuff.
