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.

I use one of these http://www2.towerhobbies.com/cgi-bin...?&I=LXK378&P=0

I mark where the engine goes, then I drill the holes in the mount with the mount removed from the model and the engine not in place.

The mounting pads of the engine can be almost to the end of the mount. I'd leave 1/8"-1/4" of the mount sticking in front of the mounting pads of the engine.

Enjoy,

Jim

I set the engine where I want it, and then put a drop of thin CA in each hole. Let it set for a few seconds, and you have four perfect holes to drill. I have put to much in, and it would run when I removed the motor, but it still leaves a raised circle. Good luck, Devin
