Why is everyone ignoring me? Do I anger you?
LOL.. Missed your question.
(was it about the motor placement?)
3" standoffs is what I am using with the DA. That seems to get the CG very close. You can move the cowl back a little to have the motor to appear to stick out further forward. That will actually help with getting more air into the cowl and help with prop efficiency.
There was a big discussion about this in the QQ 85" Yak thread.
