Thanks for getting back. As it turns out, I called into the shop it was purchased from where a young lad who was an "expert" had a look at it. After a bit of fiddling he decided to reverse the server switch on the handset for the throttle and sent it flying, quite majesticaly, into the shop roof. Once all 4 rotor blades had shattered and the tail had snapped into a couple of bits, and the heli had crunched to a stop on the floor in front of me, I was offered an exchange for a new model. It has to be one of the funniest things ive seen for a while. The new model still rotates but this time in the opposite direction (clockwise) even once it has cleared the ground and is a good 6 ft high. I will give your suggestion a try. I cant see any screws to turn on the control unit but there is a sticker on it with plus and minus symbols, so maybe the cover has to come off the control unit.
