you should hook the throttle up directly to the carb because the governer will be pushing back the higher it revs with that light flywheel -

@jettpilot1 Hi, the governor mechanism inside the block has been removed :)

Hi Rob

It's looking good so far ;-) ... can't wait to see what it does once you've got in spinning a real load ... the prop'.

Good Luck

@BrianTurboT Hello Brian, I can't wait too ;o)

Sam will hopefully be dropping the frame off on Monday, he's impressed with the welding quality his colleague has done. Watch this space.........................­............ :o)

@lookupparagliding Ha! I just thought - maybe the "naivety" element of my equation might be a bit high!

@weirwolfarroo Mmm, Mars bars.

@lookupparagliding There do seem to be some GX360 Trikes flying out there. My mate is working on the project too so it may be that he (12 st) gets to fly while I sadly watch from the feild, no doubt comfort eating a Mars Bar!
