If your plane is "trimmed" out good!.. min./no wind on your test, run a few tests to be sure...
You may have to much Rt. thrust??? the normal thrust that's needed and usuaully built into
the firewall..
If so you can add a washer/s to the top and botton mounting bolts on the side that you need it
on, on the engine mount between the mount and firewall.. You can also buy thrust plates...
But the washers work just as good If you do add washers or plates... Make sure your
bolts are long enough to go completely through the blindnuts....... Ohh & loc-tite in..
