RE: Official E-FIRESTORM thread
If they do not have the stock HPI part and you dont want to order it and wait, I would see if they have the Traxxas ESC used on the Stampede VXL. The Traxxas is Waterproof. The only issue would be that you would have to have theconnectorson the Traxxas ESC switched to Deans plugs or have the connectors on the car and your batteriesswitched to Traxxas plugs. I would switch the car and the batteries to traxxas plugs, because it opens up the availablity of alot more options in batteries. Iswitched My HPIESC to a Traxxas batteryplug and it is great!
