I wasn't sure if the standoffs were the only way to mount it; I guess I just figured since it was a small gas engine they would have given you some options. Would you happen to have any pictures of the front? How far forward of the windshield did you remove the cowl area? I built mine as a tail dragger, so I shouldn't have any issues. I also have big 5" tires on mine as well, looks cool and taxiis on grass real nice with ease. Thanks for all the info.!
