RE: Nitro models pusher Bobcat?
Polishedbrother!
Looks like a cool project! I know someone who did something similar, they ran the tuned pipe in the fuselage to keep the lines nice. Try to get your tank right over the CofG, you've got around 2lb of fuel there which will make balance interesting as the fuel burns off. if the fuel lines are long consider a pump. OR fit a turbine.... or you could fit a turbine....has anyone suggested it may be worth fitting a turbine...I'd fit a turbine!!
No seriously, it will be a cool project. best of luck!
