I've got two red painted wingtips for sale, one aluminum with the ridge along the side and one fiberglas. My airplane came with two different ones; didn't even figure it out for six months. I found two matching ones, and don't need these anymore. I'll sell them for $75 each plus shipping just to get my money back. If anyone is interested, I can send more detailed pics.
I guess a pilot who's overweight might want to put a conical camber tip on the left wing and a symmetrical tip on the other . . .call it "permanent aileron trim" . . .
You know, there's no telling how long it flew that way. They used to have Hoerners on them, Imguess they were swapped out then. It flew straight when I bought it. I just don't like things "not right" on my airplane!
