Frank it looks like you can get one straight from PA's USA shop. Here is a link http://www.precisionaerobatics.com/product_details.php?pid=390
It looks like they are out of stock until mid-March.
hs-65mg's would be great on it. They exceed the specs called for. I can't speak for the epbuddy motor but I ran that HURC motor on a 3dhs 48" edge and it was pretty decent with a 13x6.5 prop on 3s. I put a 14x7 on it but it would get a little hot but I did it anyway
