Default Update

Well I did quite a bit of flying and testing this weekend finally. A trim tab built per the previous comments worked. Still bothers me, but I can get on with things.

On the wing incidence angles- Of interest to me was that during my first stall tests, there was no discernible tendency for one wing to stall over the other. In fact, one of the first stalls I did had the left wing breaking sharply first, which would indicate to me that the incidence of the left wing was higher than the right, despite the left wing heavy flying characteristics otherwise. But, it only happened the one time that I could tell and more testing is required.

I also suspect the elevator trim tabs may be a contributing factor, but not going to mess with it until fall.

Anyway, thanks for all the inputs, and I'll keep testing and trying to get rid of that trim tab (after I get through Phase 1)!

Dwight

Here is an old elevator trim tab thread on the Matronics list. It comes up every year or two as folks finish and fly their airplanes. I set mine by this method and have never had any heavy wing problems. I have no idea if this has any relevance to your issue, but it is an interesting thread on the RV-10 elevator trim system.

Thanks David. That will help me when I am ready to align my trim tabs.

The smart level from Cleveland is accurate to 0.1. It worked very well and has come in handy numerous times. Obviously, you don't need that kind of accuracy for most parts of the build.
