RE: Heading hold
If we are discussing which pieces to get, I have put togehter a list that give outstanding performance:
Futaba gy240 $120
schulze s. 105 $55 (?) (or TREC for $74)
pixie 7p $30 (gws ics100 would be cheaper)
3 cell LiPo $35
Charger (lpc-400) $60
3 cell LiPos give better power, and more lifting capability. Needed with the heavy gy240.
The high frequency schulze controller protects the abused tail motor
I have used a lot of different configurations, setting up a half dozen piccolos and a buddy's hummingbird. The configuration I listed gives the best tail control. It is simply the easiest micro heli to fly out of the bunch of them. Any of the heli pilots that are struggling to control their birds do better when they fly this heli.
