Well I converted my O'Donnell with a mm2 setup I had and its crazy fun. Never realized what I was missing. I used to dread pulling the buggies out when they were nitro. It shouldn't be like that. It was fun when everything was working right and dialed in....but weather change....time to tune it again. That got old. Quick. Now I throw a battery in and just go. Its faster too. I get over 15 minutes run time to boot. With this budget system its just gonna make the decision to convert my other buggy easier. The only problem I have is they only offer a 2200kv and I can only fit 4# in the buggy. The 2650kv motor I have now flat out hauls on 4s. Im not so sure the 2200kv version will be as fast.
