Im short on time and not the best builder so I had mine built for me by a guy here in Chicago who does a great job. Here is the link:

The guy's name is Scott and he flies at the same field I do, that's how I found out about them. Send him an email through his page and ask him about his trainers. Maybe he will ship to you. If not he might know of someone in your area that builds them. Good Luck!
