I had one and was great. Idles for ages and went like stink.
After some months of testing this is what i came up with.
Plug OS P3 turbo..
Fuel 20% and 6% caster 6% castor.
Pipe a Jp 2 or 3.
Slightly lighter Clutch shoes to engage high in the RPM.
Gear dowm for more grunt. eg ( 76 spur than go to 75 spur)
My motor was a high rever so i had to gear it down to get a little mor torque.
I got great run time to 12 to 13 min out of a tank.
