MBJ, friend of mine had one for a while but purchased a turbine and reckoned it was cheaper to run. Buy a Hughes300 cheaper to run more reliable. 47 starter motor about £900, 300 about £250. 47 uses about 18g fuel an hour, 269B 9g 300C 11g. Plus the they still make the bits for 300's, or try an Enstrom.
If you want to play MASH thats fine but don't fly into a headwind !!!!
