I went with a 24* vee. Flattened out 1-1/4" on the bottom. Its all meant for a graupner mini jet/brushless outrunner. Here's what I have so far just waiting on parts now. Its going to be a tight squeeze. I might have to make the hatch bigger to get the battery in/out.
Hull demensions are 15.5" long 6" wide.

In the pictures the top is just taped to get an idea of how things will be. Still work to do on the hull obviously.
