So I recently dumped about 200$ on upgrades for my kyosho rage VE, bought a xerun v10 13.5T motor, Trackstar 1/8 Scale 150A ESC all powered by a graphene 3s 45C Li-PO
I've been using it for a while now and there hasn't been any damage whatsoever (or so I hope), spur gear is fine, pinion is fine, car runs like a champ. However there are 2 worrying things:
1. When I mash the throttle to WOT the car makes a loud pitch screeching noise and won't get up to speed, slipper clutch is tightened all the way in
2. When off power (in other words, anytime the car is not being accelerated by applying throttle) there is a loud sound coming from the engine/rear drivetrain
The second one is what is worrying me the most and I am scared of damaging my engine
I'll include a sound clip with the car on a stand, wheels spinning freely in the air so you can hear it yourself
