205 Motor Silicone

Back in 2023, Nick Rivera spotted a major issue: QS swapped the dependable white silicone for a bargain-bin gray compound to secure wires in their motor cores. Spoiler alert: it’s a total fail. This crumbly mess breaks apart, damages wires, and occasionally takes out the hall sensors too.

With so many motors sold, it’s impossible to know which ones have the gray compound without opening them up to check. I can’t confirm if QS has stopped using the gray compound, but I’d imagine the flood of complaints has prompted them to take action-hopefully.

Symptoms

  • Motor throwing a tantrum: bogging, jerking, or vibrating.
  • Motor taking a nap: not running at all.

Fix

  • If you’re lucky, resolder the broken connections on any intact hall sensors.
  • If not, grab a 413F (TO-92 package) hall sensor, grind out the old one, and swap it in like a pro.

Before putting it all back together, ditch as much of that flaky gray silicone as you can and lock those wires down with zip ties-because nobody has time for a repeat performance.
