Iron bay has those belts for you. I think that they are about $15 bucks apiece but I'm not sure. If they don't have any, you can get the number of the belt from them and you can purchase one on line or maybe get one from your local belt and bearing guy. Good luck on your maiden and make sure that you film it! Not too many videos of flight on this plane. I know I will video my maiden and many flights after if there are any LOL!
