RE: epp 3d plane for flatout outrunner setup
If you don't mind cutting your own epp, the slofly would be a good one. Deisgned by Steve at Slofly.com.
Another would be Mr. Flash's epp Ultimate bipe.
If you do a quick goggle you will find the plans and build logs for both. Dang near unbreakable. If not let me know and I can e-mail the files to you.
