For the revo with a 2.5r you can maybe im just saying maybe get 10 mins out of it. I usually pit arround 8 mins and with the 2.5r. OS .18tm you probably want to pit arround 7 and a 1/2 mins. Pre-race help - get to the track early and take some runs arround the track see how the truck feels make sure your engine is tuned right. Make your adjustments there. If you need help you can ask any of us at the track. You can ask me to I have a revo and will be racing today. Oh and also if you cant bring someone to pit for you can probably ask anyone there most guys will help out.
