Yesterday I had my heli out at the field. I was checking the tracking of the main rotor, 500 mm. blades around 1/4 throttle (500 rpm). It was out about 3/16"-1/4".
My problem was, I noticed the cyclic was moving on it's own. Not drastic, but airborn I probably would have been fighting it. I did not take it up. When I got it back to the bench, the only thing I found, outside of blade tracking was a bit of play of the rotor head to the main shaft, parallel with blades and none perpendicular to blades. Now I'm thinking. If the tracking is out and I have a bit of play of the rotor head to shaft maybe the servos are not strong enough to handle the push/pull applied to them just sitting at neutral! The servo's I am running on cyclic are JR Nes-L501 / 40 oz in, .30sec/60 degrees, Teflon Bushing, nylon gears, 5 pole ferrite motor. These are older servo's around mid 80's
Are these servos strong enough for this application on a 30 size bird, and would the tracking cause the cyclic to float like that or the minute play on the head, or all three?
