I recently recieved a Cub arf from a friend. It has a 79" wingspan and weighs 8 Lbs. As you can see from the photos the engine was mounted high on the firewall and I want to lower the mounting point on the engine by one inch. Is that OK? Who makes this plane as a new cowl would dress up things quite a bit. CG on the spar??? It came with a MECOA .46 and I plan to install a K&B Sportster .65


Thanks
