Hey, I just recently got a Hangar 9 Twist 3D, and I'm wondering if there is a easy way to figure out how to drill the holes in the engine mount? The cheeks keep getting in the way of a drill and just about any sort of marking device I can think of. I'm using a O.S. .46 AX engine and from what I've read, I have to mount the engine as far forward as possible to keep the plane balanced. How far away from the front of the engine mount is too far before I'm in danger of the holes ripping apart while the engine is running? I'm thumbing through the Hangar 9 Twist thread but at 119 pages, its taking quite a while. Thanks for any help.
