Bob,
How about the vertical up line? And knife edge flight? Does it push or pull or both? You may need to make a slight CG adjustment forward. Reducing wing incidence may not produce the desired result and may change other flight characteristics particularly in knife edge. Let's work these out one by one. We can discuss this through PMs

BTW- Ed found that ACP carries the perfect size carbon braid tube for laminating carbon/wood composites. The 1" size is about perfect. We built an 18x12 for him last night and it went together particularly easily. Just some small amount of flash and very little trimming needed in the finished product. We laminated the whole prop including the hub for extra safety margin. I'll post pics when I get it out of the vacuum bag
Matt, before I change any control surfaces I will fly it in calm conditions to see what it's really doing. Was flying last Saturday in a dead crosswind and quartering crosswind of 10-12 mph from behind, so not a good situation for evaluating anything.
Good to hear that about the props and how you guys keep making it simpler to fashion one. Actually I had been giving some thought to the failures I have seen (2 or 3, with IMAC planes) with wood props and it seems they break at the base of the blade near the hub. Glad to hear that your CF sock now covers that area. How are the props in your original batch holding up?
