Any good 50 will do what you want. Raptor, Sceadu, or Raven

I prefer the Raptor - most popular heli by a large margin. Very easy to find experienced help for. In my area we have maybe 30 pilots, only a couple of them that i am aware of do not own a rappy. Heli folks are generally pretty helpfull, and will assist even if it is an unfamiliar heli, but it does make it easier to work on one that is familiar. check on what people recomend in your area.

Rappy 30 and 50 use same frame and mostly the same parts, which i can get from the local shop. I broke one on friday, by friday night it was ready to go again. local parts supply comes in handy now and then. Check on what parts are stocked at your local shop.
