Hello Telemaster
I just had a look at the plans for your bird and the center of gravity(C/G) seems to far rearward. Either a mistake was made when the plans were drawn or the plans were not properly tested. The C/G symbol is not very prominent either though it is one of the more important bits of information on a planset, I see this quite often. go slowly when changing the C/G.
What is your bird doing in flight? if aileron sensitive the C/C is surely rearward.
My eye gets better as each day passes it will be a week or So before they do the other, I think I may have 20/20 vision when finished.
thank you!
