RE: Hk600 tail not holding
Solman is correct...With any heli when a tail blows out, this is due to the tail not being able to keep up with the sudden increase in main head speed. Happens with t.t helis as well. Lower your head speed. dial in your gyro again to wher its a rock solid holding. ( gp780 is an excellent gyro) And from ther just tweak your head speed back up and gyro settings to match. Again a sudden thrust in headspeed will blow a tail out if not properly dialed in.
