Has anyone converted a hotbodies lightning stadium pro????

Well I have a update! I have received my RC-Monster mount Came in lightning time. Happy with that shipping was alot for something that weighs ounces. I have added the brake servo for the mechanical brake. I will post pics when I figure it out. My next question is? I looking for top speed. I saw on ebay A new monster mamba for around 250.00 for the 2200kv set up. Or should I go for a 1600kv to 1700kv. for a 6 cell battery that I currently own. I found a losi xcelorin 2100kv set up for around 225.00.
