The throttle tube is super easy to install. I knew it would only take a few minutes, so I set up my GoPro in Timelapse mode to capture the magic! :D
Maybe someone will find this useful?

Here is a basic video from COTA. The track is very big, and smooth. I never expected to enjoy riding the little RC on such a fast track, but it was't bad at all!
Also, I have to give a very special thanks to Matt at Formula390 for hanging out all day and providing such great support / company...
