1.) Reversing the flat metal detent spring will solve that problem. Works just fine for fixed wing (I started with fixed wing).

2.) Learning curve? Don't worry about it. I read somewhere a while back that says is all, remember that there is no time limit. Just try to be a little better each time you go out.

3.) I personally fly a Hawk Sport and think it is the best choice for a beginner (or experienced pilot) but, as stated, most of the available helicopters get the job done. If you have a well stocked local hobby shop, consider what they offer. You might want to consider a 50 or 60 size machine. More money but also much more stable and visible. Obviously your radio won't be a problem. I use a 9C myself.
