Was breaking in my 3 port race spec the other day... Had gone through several tanks on the box, just plopped it down on a parking lot surface, put about 2 tanks through it just fine, but on the third tank, I guess my receiver pack randomly dumped, and it went to 3/4 throttle runaway. About 5 seconds into the runaway I regained control only long enough for it to flip upside down, and go back to 3/4 throttle. My heart sank. I ran at full throttle to it and plugged the pipe with my knee.

Got it home and it actually doesn't look like I had a runaway at all. The rod and everything appears fine.


Only time will tell.
