Ricky, there is a guy that built riggers (Jae and possibly others). You can buy them pre assembled from him. His name is Mike walker, he is also on this forum. Not sure if he still builds them. I would suggest to check with him.
Looks great again.
What I've seen with long rudder brackets is to add a horizontal brace for stiffening instead of vertical.
Do you feel it was going up and down?
I've also upgraded mine to lipo and got a ubec voltage regulator for free back then from Boris, what a great service that was. I run mine on 5v, thar is what Boris recommended.
