I have purchased this plane and so far seems to be going together well. This is my first glow powered plane and I can't wait until it's ready to fly. I have been taking my time with the build and it is coming along nicely. I will be using the new O.S. 46AX for power. I am a little confused on the engine mounting. The instructions call for aligningthe to marks on the mounts with the lines scored on the firewall. If I mount them that way the engine will be way off center. What I have done is mount the engine temporarily to the mounts and line the engine up with the center of the cowl. Can somebody please tell me if this will be ok or give me some ideas to get it correct? I know I will need to cut out some portion of the cowl bottom for the muffler. I just need some advice.
