A 13x8 prop will rev to 7200 rpm - with absolutely NO pull! A 13x5 will rev to 10,500 freely - plenty of pull on take off. Apparently most of my take off problems are related to poor prop selection.

The motor mount has been shimmed with 2 washers at the bottom - kicking the thrust angle back up to -2 degrees.

The wing was shimmed to adjust it to +1/2 degree from - 1/2 degree.

The static setting of the ailerons resulted in them being "down" resulting in an unintended "flaperon" alignment - nosing the plane over with neutral aileron settings.

What I learned:
Before covering - determine adherence to manufacturer's incidence guidelines and adjust as necessary.
Before flying - talk to locals about prop selection (we're well over 5000 feet where normal hobby standards just don't cut it)
Make sure that static control surface adjustment is close.

Cheers,
