I got me an XO roller off Ebay and have a MMM 2200KV motor that I am going to put in it. I heard that the 2200 Motors will get these things to 100MPH but will heat up fast. I was thinking of ways to cool the motor via a water cooling system. Would it be a good idea to just wrap copper tubing around the motor can or is there an actual sleeve made for these motors? I want my XO-1 do more then just two passes before reaching TS. And I think a water cooling system might be my best bet. I may even do a small water tank that I can fill with Ice. maybe a cube or two might last me enough time make it though one charge. Just thinking out loud here but tell me what you guys think. Any tips and tricks as well as a "Parts list" would be great. Thx all.
