That’s a good idea, not sure I have the skills to cut and join a fuel tank tho, but 7-8 mins would be spot on. I’v got the timer set at 7:30 on my Xcalibur with the 120 fitted and with the 3 (ish) litre tank always got fuel to spare. and I’m sure the Joker will need less throttle for cruising around. But I’d rather have more than less fuel. Would you be willing to sell a M&R modified tank? :-) :-)
