Hi!
Before you go to any more length in building the Kyosho DC-3 ....check the wings for wash-out...or wash-in...which is disastrous!
It is rumored that Kyosho discontinued these ships because the wings were wrongly cut/built!
I have seen two of these airplane start...not one leaving ground...they all "snapped"at the moment leaving ground.
If the wings are built with wash-in, which is no good ...this could be fixed with a little labour!
Check them out before you do anything else.

Regards!
