Mike I found with my Diehl setup that the toe in caused the camber to vary as the aircraft was wheeled around backwards on the hanger floor, that is, the wheels were being forced gently outwards leading to different angles on the legs and giving the impression that camber was at fault. Have you checked that leg geometry is at least symetrical when the weight is off the gear as a first step? If so, check each of the lower brackets for symmetry. If still out by 4° then it might be easiest just to make up one new bracket so that both are the same. Only other thing could be a bent axle.

I sat there in a very pissed off mood measuring and re-measuring again only to find that the lower gear brackets do not share the same angle formed between the gear leg and the axle. As a matter of fact, it turns out that between the two, they're several degrees off (about 4 degrees). For those of you messing around with gear geometry at this point in your life, you know that this is a lot of degrees. I can't understand this - it never occurred to me to check this prior to bolting them to the gear legs. In fairness to the people at Diehl, I bought the assembly second-hand, but it obviously was not damaged. And judging from what I see on the web, it sure looks like a Diehl assembly. Moreover, a shim is really not going to work very well - a quick computation with my CAD program indicates that a 4 degree tapered shim behind the axle is about .210 thick. I'm just sick about this mess. Anybody out there got any clever solutions short of ripping my plane apart again? > > Mike Meyer _______________________________________________ > see KRnet list details at http://www.krnet.org/instructions.html > >
