Default RE: Top Flite Staggerwing

I just pulled mine out of winter storage and repair, to measure it for you. My CG is at the 5.5" mark, my field finger test points might be back 1/8". Mine is electric, so the batteries can be moved slightly to adjust.

My elevator movement is set at 3/4" up and down, 5/8 up on dual rate, but I never use it. I use 40%expo on all settings to smooth out the center, normal flying area. The only time full elevator is ever used is... I don't think I've ever used it on this plane, except when taxiing. This plane is properly flown at high speed, wide open manuevers, not full throw for anything.

I did look closely at my elevator "center". It might be 1/32" up. Checked the centering on the transmitter, and it shows 6% up trim, so I could still be a smidgen nose heavy. But I like the way it flies there. My first flight, the maiden, I did not turn it upside down. I went straight up from the point and held it under top wing. WRONG!! It came out very tailheavy. Only my long years of experience and my R/C helicopter experience, (FAST thumbs!) allowed me to save it. It took two lbs on the firewall to balance. That was with the OS 1.60 TwinFS. With my electric setup, on 10cell lipos, I still have 8 oz on the motor mounts.

During it's rebuild, (new wings required,) I may strip all the fuse stuff in the rear of the fuse, also. The only one required is the tailwheel mount. I use the air ram to operate it, but it's up on the servo mount rail in front. Pushrod going back.
