Tired of constantly servicing brushes and chasing unreliable speed? When an accidental warranty mix-up from Horizon Hobby landed a brushless speed control on my doorstep, it was the push I needed to finally ditch the brushed setup on our Arrma Fury.

In this post, we dive into the messy, hilarious process of upgrading to a Spektrum 4000KV 550 brushless motor—complete with transmitter calibration mix-ups, backward servo plugs, and a chassis that now pulls full-on wheelies in the dirt. If you are on the fence about whether to make the jump from brushed to brushless, grab a wrench and find out why the upgrade is well worth the chaos.
