Hey guys, just flew my new Sledge that Morris built for me today for the first time. Couldn't get it to fly level hands off. Few clicks of up and it went verticle. Didn't try inverted cause I was to nervous. CG is 4 5/16 from leading edge. Elevator seemed real sensitive. Any suggestions?

Hmm. What servo are you using? You know my buddy has an OMP Edge 540, and was using a Hitec and everytime he flew it the elevator trim would be off ONLY when he flew. On the ground you couldn't tell unless you checked everytime. His first flight resulted in loops! However, he swapped a new Hitec and all is good. I think the old one has had better days, being in a few planes before the profile.

Could very well be C of G, and sounds like it. When an elevator is sensitive, that tells me its tailheavy.

Might have the clevis in too far. High rates should get you 45 degrees or so and not stall the servo. If its in too far one click of trim is a fairly big change. Mine starts climbing inverted when the cg's around 4 1/2.

If the pull pulls are to tight it will not center correctly either.

Set up is wrong somewhere, it is that simple. CG is where I would start, I have never measured it but I shoot for right behind the secondary spar at the fuselage. Try getting it near that and then let us know, we will go to step two from there.

i really reaknon its your CG.

Hey guys, I found a goofy acting s9202 servo on the elevator. Changed it today with a standard bb that I had at home. Elevator does not seem to center properly. Tried adjusting cable, and changing servos again. Still doesnt return to center when I give it full deflection down. I tried the cables looser and tighter. Did not have this problem on my Top Cap. What am I doing wrong?
