Have a look at the Thunder tiger Raptor 30 or 50 loads still about.Sturdy and can handle wind better than small electrics, You do not have to go the electric route, I have a unflown as yet Raptor 30 V@ with OS 32 heli engine i still use 35Mhz gear in all my aircraft it all still works fine.
Check out the model shop websites for availability or you can get some bargains from the bay or bmfa site somtimes.
I have dabbled in electric but prefer I/C engines every time.
Good luck Chris
