we have already done it .... we converted an MRX3 last summer and will be developing the car further this spring as we wait for good weather. As quoted by Paul Lemuix" the fastest RC car he has ever driven" just need to get run-time a bit longer, and get some of the battery weight off the front end of the car.
The car really came around when we put in the RX8 speedo......
here is a couple poor quality shots........
