RE: ESM 50cc Corsair
On this one it is pretty easy. To Make sure that they are exactly the way you want them. You should measure and drill your holes in the fuse side first. I would go a smaller size drill bit than it calls for to begin with. I would drill the holes in the fuse. I then would mount the fuse onto the wing and then reach inside the fuse ( through the firewall opening)using the same size drill bit. I would push the bit from the insde and turn it to mark your holes on the front of the wing. ESM has always just had you measure and drill. I have always been uneasy doing this but I have not messed up yet.
