Flying a glow trainer and an Aerobird is going to be different, maybe more different than you realize. I'm not saying you can't do it, just be careful.

Keep in mind that a glow trainer travels around 4-6 TIMES faster in level flight, so it gets a lot farther away a lot faster, and when things go wrong they can go wrong fast.

You can take the wheels off and hand lanuch it, but hand launching a .40 size trainer is not easy, and not something you want to do by yourself. You'd do better finding a surface to use as a runway. You can get bigger wheels than normal to help with rough ground.
