Thanks for the positive comments guys. Jim no mods to the XS only a service and check over, I do have plans for a monster engine but will need a new chassis. Luckily one of my mates kids recorded a video of the start up and has posted it on facebook. I am not a member of facebook but you can read it without being a member. Even without the RD video its a good read. https://www.facebook.com/pages/category/Personal-Blog/dowman_racing-1900237280084327/ Turn the sound up.
