RE: eagle 50 helicopter
Well, the swashplate has 4 parts, a small bushing in the upper plate, a larger "bearing" in the lower plate and the two "plates." The upper plate has links to the upper part of the head, the lower plate has links from the servos. The upper plate spins with the rotor, the lower doesn't spin but is tilted, or raised or lowered by the servos. The two plates pull apart when the servos pull down (which is increasing rotor pitch) more than about half throttle / pitch on the tx.
I know, probably clear as mud!!
Tnx
