Your expert second opinion is requested to see if I am on the right track. I just built a giant spad profile with a Ryobi gasser on her. Pictures are in the spad forum. Anyway I wanted to compare the way I set it up with some of the profiles here on RCU.

On the test flight she would climb with throttle, so as to require down trim. Of course when you go to land and throttle back she drops her nose due to the down trim.

I had some slight droop in the ailerons and if I compare it to planes like the something extra they seem to have the ailerons with a slight up to them. Are some of your profiles set up the same. I was also thinking that some down thrust in the engine might be required. Does your profiles have down thrust?. Just looking for some comparison.

My setup has 0 down or up thrust. Slight right thrust. The wing and horizontal tail feathers are all in line with the thrust line and 0 deg. of incidence.

Thanks in advance folks.
