Ok i have a couple suggestions:
1. anytime you see your neihbor running the awn mower, that would be a mighty fine time to crank up the rc.
2.You can try some silicone (high temp) fuel line over your stinger.
(end of the pipe) and the longer it is the less the noise should be. But keep in mind that if you get crazy long, you are possibly looking at some exhaust flow/overheating probs.
3.electric conversions are the latest greatest thing out there.
