Yes, it seems so obvious now but I just didn't get there - DOC over here is Dept of Conservation (not the heli pilot's best friend by all accounts) and I couldn't get past that!
Sad to hear about the grip thing, its a good old bus and I hope they sort it. Really enjoyed mine after 22, it's the best way to learn how to use a throttle ! I'll find out what it cost p/h and send it to you.
I beleive that FAST at Thruxton are (maybe now were!) running one for training. There are one or two owners in the HCGB that might help too.
