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.
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.
