| I found the perfect way to test for belt static and even static from the main gear and motor pinon. I found 4 different test probes ranging from 10-20 dollars. You can get these from electronics stores along with the conductive carbon grease which I paid 18 dollars for.
Why use your expensive heli as the test platform? When you can use a probe on the heli sitting on the bench.
The grease looks just like grafite, except it has silicon as the base, this stuff cleans up with dollar store windex, it has no petrols in it and it's thick enough to stay on the belt.
This grease kills static in 2 ways, it lubes and it's conductive thus shorting out static right at the source, it never hardens and it stays on the belt lasting 200 flights maybe more.
I applyed a small amount to a piece of shrink tubing, and tested it with an ohm meter to show the conductive property of it.
Paint it on the inside of the belt teeth. Apply some on the main gear, I saw video's of a guy having static on his main gear, better to be safe.
Spin the heli up without the main and tail rotor blades, move the probe along the boom and check near the main gear if the probe does not flash you can fly safely. If you have plastic tail rotor blades, you may see static on the probe from them, best to put some carbon fiber tail blades.
The probe can pick up AC fields so make sure you have no AC extension cords laying near the heli.
