Not sure if i can open up those chinese rings to lube them but i got some dielectric grease on hand.
Heck, i might try and pump it inside through the seals with my grease gun needle

I also thought of using some capacitors on either side of the ring but wonder if it would just create a bigger spark ??

In fact, the rings are rated for 2 amps per wire and i only need to power 2 tactic tsx45 servos

Yeah, on a roughly 1:20 scale plastic excavator, getting a full set of battery/bec/receiver down there seems pretty optimistic
I could probably get it done though, with a small ~800mah 2s Lipo, 8-10amp BEC and micro receiver.
Now the question is, can i control 2 receivers at the same time with my taranis
Can't sleep until i find out now, thanks alot !!
