After learning on my 4ch micro heli I bought an CopterX heli (450 size). It is soon much easier to fly, I would recommend a 450 Trex copy like the CopterX.
Your besdt option is to buy an RTF (ready to fly) heli and practice on a flight sim with the transmitter and sin cable. Remember a crash on the sim is going to cost you money in real flight! I can fly inverted and do some tricks… on the sim! Real life I binned it and bought a whole kit as it was cheaper than buying the parts I needed. You will need blades, they will be ruined after trying to lift off the first time. Also you will need to setup the heli for it to fly, loads of forums and videos, you don’t need to join as club, but it will help.. maybe join one without your sun knowing, so he can be in wee of your skillz?
As above.. be careful, these things can kill or seriously wound someone. There is no way I would let anyone use my heli, unless I have seen them fly.
Best piece of advice is to hook up the tranny to a PC sim and when you can fly without any crashes, and do manouvers, then you can try the real thing.
