I have moved the CG back some and now the Seamaster does the neatest lumshavocs. - bad spelling- It will flip end over end about 2 1/2 to 3 times.
The Seamaster does some pretty nice spins too. Although the plane can sometimes be a bear to get out of a spin. I have had a couple of close calls.
It flies pretty well upside down to.
This plane will do alot if set up correctly.
It is a great plane. All with an OS 52 four stroke.
