Not sure what you mean, but I installed my motor so that it was parallel to the nose ring on the fuse. The nose ring has the proper lateral and vertical thrust built in, so just make your motor firewall parallel to the nose ring. The best way I have found is to install the motor on the firewall, put the firewall/motor into the fuse, mount the spinner with at least 1/16th" spacer on the back of it, and then line the spinner up flush with the fuse nose ring. Tack the firewall in place and then aeropoxy it in.
