Yep, I know I used it everytime on the track. My truggy engine had two tanks ran through it before this weekend, and even with the low temps, it was a breeze to fire and tune and ran flawless all week thanks to the heater. I always said that 2.4 radios and personal transponders were the top 2 things to ever hit the market, and I think this ranks in at 3rd. Almost seems like a preferred necessity at any event, warm or cold outside.
