RE: Is this a good first trainer ???
Cubs are more sensitve to your takeoff technique as mentioned, and they are corks in the wind. Since the OP is without a plane at the moment though, I'll chime in. For guys with some RC experience, I say skip the trainer and buy an Ugly Stick. Everybody makes one and all of them are good. They are easy to take off, easy to land, good in the wind, can do any aerobatics you want, and are really forgiving of bad piloting. The only gripe is that they don't have the training wheels to save you from yourself, but if you can pay attention to what the plane is doing then you'll be fine.
