Just a thought but I know that vibration was an issue with some of the early receivers from Spectrum. So much so that they wanted you to open the case on some receivers and put dabs of hot glue on certain components. How is your receiver mounted? Is it mounted in foam or is it hard mounted to the battery tray or servo frame.

Since 2.4 claims to be free from electrical interference I would tend to think perhaps vibration is causing the issue and not static. Especially if you can't duplicate it on the bench. Perhaps a broken wire in the switch or a bad switch all together. Have you balanced the rotor head, blades, clutch/fan assembly, tail rotor etc. and made sure the engine is lined up with the clutch bell.


I'm using an AR7000 in my Sceadu and its mounted to the frame with zeal tape as well as the remote receiver. Havent had any static issues with it to date.
