Vinny,
That's a popular misconception. Fuel sloshing around in a tank will not generate static electricity. It takes FLOW to generate static electricity in fuel. The higher the flow the more static is generated. Even the higher fuel consumption of the larger engines will not generate a significant amount of static.

Most static is generated during fuel fill. The reason we are seeing more of this on planes with bigger engines is that they have bigger tanks and if you try to fill them in two minutes you can generate a significant charge. The amount of humidity in the air and the conductivity of the fuel being used also have an impact on the amount of static generated.

Keith's problem sounds like it could be static related. The best way to minimize static is to slow down your fill rates. Use a lower voltage battery on your fill can. Larger diameter fuel lines will also help. If you wish to learn more read this thread: http://www.rcuniverse.com/forum/m_49...%2Cfill/tm.htm
