Pjtg0707,
Here's some pics of eng and cowl. The engine mount is already mounted at a 45 degree angle for you. And there is a muffler relief cut out in the bottom of the fues. Although it wasn't quite big enough for the oversize Tower Hobbies .46 muffler. Had a Macs Pipe for it anyway, it works out great. There is not much left of the right side of the cowl after trimming around that 45 degree engine. Looks nice though. I didn't trim any off of the rear of the cowl. I left it long.
