I am fairly new to this very addicting hobby, and will be flying or at least attempting to fly as long as my bank let's me. My instructor is getting ready to move back to the U.S and gave me a Cap 21 to build on until I become one of those ole ace of the sky pilots. The building instructions are extremely vague to say the least. I fully understand the requirement of having right thrust, but my instructions do not say how to obtain it. Should I offset the firewall a few degree's or mount the firewall straight and shim the engine mount a few degree's. I am in no hurry to finish this project. I just want to build it the best way possible. This is my first building experience. Thanks for the input and welcome to 2005!

Who's the Manufacturer?

The right thrust is either built in, or needs to be added, but the instructions should make some mention of it.

On the other hand, maybe that particular MFGR doesn't call for right thrust.

If no reccomendations are given. Build it as suggested in the plans. You can always make a shim out of hardwood for under one side of the mount to add the right thrust later if you need it. With a Cap style plane more than likely you will not need or want any.
