You can buy a dummy transmitter with FMS from some places...for about 26 quid I think.
I used FMS for a very long time...not a bad sim...taught me a lot.
Get good on the sim, learn to hover and keep it in one place. learn to hover with the heli pointing all over the place...fly backwards, forwards, sideways....all ways!!!
you get out what you put in with a sim.
