I am assembling an Oasis electric pattern-type plane (from Value Hobby)
The firewall is tapered to provide some right thrust, but I don't measure and right thrust when the
motor is mounted. I think the factory assembly is sloppy and the firewall is out of alignment.

What is a "normal" amount of right thrust?
I installed shims to provide 2 deg, but this "looks" excessive....

This is a 3 1/2 lb electric, not in the F3A size class.... but I expect the thrust line adjustments
may be similar.

I will do final adjustment after first flights, but the right thrust does affect how the cowl is installed.
I would like to be close when I install the cowl....

Thanks for any help
