Hi Don-
Read with great interest your thread on the original ACE 4-40 bipe. I have been searching for this plane/kit for over a yr. FINNALY GOT IT. I am restoring a well built plane that been sitting for 6yrs. I need a little help from you or any proud owner of this great plane. As you mentioned I am trying to get plans form RCM.( IS RCM = RC Modler).
In the meantime can I pick your brains? What are the incidences? Mine is 0 on the stab, 0 on the lower wing, is this right? What should top wing be? Also any downthrust/or right on engine? Where is Cg? ON strut of lower wing?

Also curious that mine has no interplane struts- just cabanes. Also only strip airlerons on lower wing. Is this the stock build? Does plane fly OKay this way? What would be good throws on all controls?

As you can see I need help. Anyone pls chime in.
