You have several good options for a beginner heli. In the 30 size range the ones I recommend are the Raptor 30, Caliber 30, and Sceadu EVO 30. You can pick up an OS 32 pretty cheap now but might want to consider getting an OS 37 for a little extra power. If you are interested in getting into aerobatics I would recommend a 50 size heli. In this class I would recommend the Raptor 50 or Sceadu EVO 50. The Raptor has excellent parts availability and parts cost is less (very important when learning) but I am a big fan of the Sceadu EVO design and flight characteristics. For a 50 sie heli the OS 50 Hyper engine is great.
