I ran my first tank on the plane and outdoors and used just enough speed to move it around.
This also allowed me to play with the controls.
Blew lots of smoke just like the book for OS-40 said.
The second tank I made short hops and then tied down the tail I held the engine at different RPM's.
The third tank I let it go and took it up to about 30 feet and was going to set it down but I gave full bore and elevator and she took to the sky.
When you get time will you please measure the dihedral on your trainer?
I'd like to compare it with mine.
Thanks 
Excuse my ignorance but what does dihedral mean
