super cub
hello, i need help i have aquired a super cub from a friend of a friend lol and i need help with a few things first i dont know who makes it but it has an 86 inch ws and is fully detailed with instruments, skylight and cowl with dummy engines. my question is will a 91 4 stroke fly it? and the next question is how do i find the thrust line to mount the engine? the firewall has so many holes in it i cant find the original ones to use they have been either epoxied over or just left open. and the final question is where the heck do i find the cg for it. i need help because there was no paperwork with it and it was freeeee>
