I'm building my first R/C plane (a SIG Four-Star 40). When I drilled the 4 holes in the firewall to mount the engine mounts I screwed up. The holes are about 1/8" too close together. The engine will not fit between the mounts.
I measured and checked and measured again. I don't know what I did wrong, but I know have a firewall with the wrong holes.
Can anyone offer me suggestions on how to fix this? The wrong holes are too close to where the right holes belong to redrill. I'd just end up with elongated holes. Also, I don't have a drill press so I couldn't easily do that in any case.
Thanks for any help you might offer.
