OK, so I've been working on my Cobra. I figured I'd have to change out the elevator horn because the 2 to 3 hookup seemed to have problems. In flying, the thing was just too quick. I tend to set up my controls to be very, very slow and use a lot of line spacing to fine tune the feel. But with the Cobra, I ended up with very narrow line spacing (to the point of complete loss of control feel) in order to get it to be controlable ... sorta.
Anyway, after a lot of thought, I decided that the 2 to 3 hook up of the controls (per plan) wasn't really the problem, it was the pivot distance at the bellcrank. I decided that the pushrod pivot was just too far from the center and I was getting too much and too fast of movement. So I cut in and had to drill a new hole in the bellcrank and move the pushrod closer to the pivot. Nice thing about an I-Beam is no center sheeting. So just had to cut into the top and bottom block. Anyway, I moved the thing in about 3/16" of an inch and now, while I still get the 2 to 3 movement, I have a lot more throw the controls should be substantially slowed down. So that was easier than I thought it would be (did have to put a new ball link in - long story on the that).
I picked up some 30 minute stripper at the local hardware place. Turns out it works a bit too well. It went right through the paint, silkspan and all right down to the wood. Doesn't seem to have any effect on the balsa, but it takes EVERYTHING off. Sigh... So it will be starting from scratch. Not a bad thing since this was a quicky finish that was very heavy.
I figure to take as much as 6oz off the final weight with a new finish. Fun Stuff.
