just bought a new GP Waco and with the engine installed it looks like there is about 4 degrees up thrust on the firewall, Is there anybody that has built this plane and if so, did you have to do any modification to the firewall because from what I understand you should have down thrust on it, any info would be helpful
Thanks

Use a trammel line and verify the upthrust from the centerline of the fuse. If it is there, shim the motor mounts accordingly.
