Well got pizza for lunch and went and did some more jumping/running in the backyard and after about 2 hours of more running disaster struck
.............. I hit a jump wrong which sent the buggy flipping towards my son (21 months) who was playing in little sand pit and the buggy struck him in the head and split his head open. So trip to the hospital for the poor little guy. He was ok, but lost alot of blood.
The MMM is still going strong though, it seems to have more punch and better throttle response with the new firmware.
