This is Ed Wilson of Leading Edge Airfoils discussing Rotax Fan Belt Tension from the movie "Ultralight HangarTalk - Tips, Tricks & Techniques - Part 2"
Super handy video thanks, been looking for this exact info for a while, needs a title with some spaces and the name Rotax or something, cause I only found it after extensive searching and some dumb luck.
It is actually a segment from a larger video which was part of the "HangarTalk" series. You can find these compiled here: www.fitzvideo.com/Pages/Launch_Ultralights.htm Blue Skies & Tailwinds!™ The Sky Surfer
