Lets discuss static for a moment –
While today’s RC systems and ECU’s are more robust than ever, Static has proven to be a prevalent issue that should not be ignored………..
So the static can build up to high levels on one part of the aircraft, with no way of dissipating. When it gets to a certain level it will arc to the nearest conductive surface, interfering dangerously with the radio control electronics on the aircraft and other low voltage systems…….This can and does cause ''glitches'' in the control system, either shutting down the receiver momentarily, or sending random control commands to the servos or ECU. I have personally experienced an RX reboot on our turbine test stand when static discharged into one of the RX antennas.
In practice, we want to try and keep the fuel system separated from all wiring and electronics. And, if possible, avoid crossings of wires and fuel tubing’s. If they must cross, leave a few inches of separation.
Hi Todd. Great thread, (and a good diversion from FEJ woes).
I personally have not experienced a confirmed static discharge problem, BUT, have had a receiver issue that might have been static related. I would be very interested in any practical advice on how to avoid it.
You suggest we should try to avoid crossing of wires and fuel tubing, or keep a few inches separation.
I think that this would be impossible on all but the biggest jets. (You would need a cavernous fuselage.) Certainly impossible with a Bandit or Flash. And it is obvious that most of the “Nice” installs in this and the other thread have fuel lines and tanks/UATs right next to Rxs, ECUs and their associated wiring. These jets obviously do no suffer from it.. Static discharge seems to be almost a randomly arising issue!!

And FWIW, I put the shut off valve after the pump..
