Once you have mastered the RCH Trainer, it's time to move up to something that is a little more challenging. The RCH Edge 540 is just the ticket. This plane has a very low wing load, is very quick on the sticks, and can be made to fly very stable with the right settings. As always, if you have any questions, or need any help with the build, all you have to do is post up and ask. We are here to help you out.
