I Found a Hidden 4 MPH in My Typhon Grom! 🤯 55 MPH on the SAME 2S Battery!

I thought this brushless Typhon Grom build was finished after hitting 51 MPH on 2S... Then I noticed something I completely overlooked during the conversion. The stock ARRMA brushed motor heatsink appears to do more than just cool the motor. After reinstalling it on my 28mm brushless motor, the drivetrain rolled noticeably freer. Same motor. Same ESC. Same gearing. Same UDIRC 2S battery. The only change was restoring what I believe is part of the original drivetrain alignment. Back out for a quick verification run... 🚀 55 MPH on 2S! I wasn't even at full throttle before I clipped a storm drain and sacrificed one of my foam tires. Thankfully, the Typhon Grom survived without any damage! Have you noticed the same thing during your Grom brushless conversion? Let me know in the comments.
