Bob, Many use the washers method. 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!
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?

Bobby, I
am sure we can get it right. 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. Jerry
