I'm loving the run time from both engines in truggy. Over twelve minutes for both with the Plus4 consistently closer to 14 minutes. This is on tracks that are probably medium sized, much smaller than the Nitro pit. Sizes average about 200 x 100 or close to it. And usually the front or back is a full straight.

These two have performed flawless for many, many gallons and oh so consistent. I'm in hog heaven and thank Monty for your services sir. So it looks like I'm gonna need another plus4 from you sir if you still have them available.
