I’m fairly new to rc planes. I started with an aeroscout that I instantly got stuck in a tree and couldnt get out. Got a foamboard trainer from flite test, used it as a test dummy till it was in an unflyable state. I now got a ft mini mustang. I put it together pretty poorly, that tail is a little crooked. Trimmed it still flies fine. I practiced low passes since it was fun and was good for learning control, though my wingtips are looking worse for wear as a result. Now I want to go a little further. Loops are pretty simple, but every time I try to roll it dives downward. I tried to fix that with the elevator, no improvements. Any tips for a new flier?
