Re: Q1 Powerplant Change

The workmanship looks good. However:

The design of the area between the bottom of the cheeks and the top of the canard is a big aerodynamic boo-boo. The interference drag will cost you big mph on the top end. Also, there is some speculation that the wake from that area may cause loss of aileron control at low air speeds. Please be careful and do a full flight test program including low speed handling tests and crossed controls tests.
