I triple reccommend realflight sim, will help 10 fold, and any coaxial heli will be fun, and easier to learn. A mx2 for indoors or a cx 2 for out is great. I had an axe cp, and currently run a mod over blade 400, mx, and a trex 600 nsp. I have about 4k in the trex 600 and radio, so believe u me, the sim is worth it LOL.
