Built into the mount would be best. Better yet a truly clever counter rotating prop set would be super. Then fin offset could also be zero for max efficiency! Bill Jepson My kit suggest to install washers between my mount and the firewall to get the thrust I need. This doesnt sound like a very good way to do it to me. Is this really the norm for adjusting thrust?

I am interested in Blake's suggestion because I can do the drilling of the S-beam on the mill where I have more control. We can also do something like you have just suggested by measuring from a point on the S beam back to the firewall. And then instead of moving the motor around, I can just move the firewall. Same thing in reverse.
