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?
That's a wise move.
The hub area is probably a little weaker than it should be. And since these are electric types with the reduced thickness at the hub, it could be even more so.
The first step is to place a short length of carbon sock over the center section, extending about 1/2" to the blade area. Then the full length piece covers averything
