I've finally found a way to mount these motors to be able
to adjust them in the field in just seconds. I could kick myself
for not thinking of it before.
Hot glue the motor to a hard balsa stick, notch the stick at the
ends, and then mount it to the wing using a rubber band. Much
the same way they mount wings to a fuselage.
Now you can easily move the motors to any spot along the wing,
at any angle and adjust the steering in an instant. Shims can be
cut and tested without gluing or taping to move the motors up
or down. All done without a tear down in just seconds.
Should have some pics of it later.
On foam wings care should be taken not to notch the wing but
scotch tape could be applied to the trailing edge to prevent that.
