That would have been an interesting sight Ed.
The flamethrower problem has been sorted. The culprit was a remote "switch" I was using in the +ive line to the pump. The switch was feeding receiver power to the pump as soon as fuel ramp started resulting in a spectacular show. Bypassed the switch and all worked normally. It will be replaced with a proper relay ASAP. Latest estimate for inspection and first flight is on Saturday morning.
