I bought a SH 18 Engine from a www.rcecho.com
and put on the tmaxx. I have it broken in and run it at around 230-245 with lots of power. But if I barely bump the HSN it comes alive but the temps are around 250-260 maybe 265 on a warm day. When it is set that way it flips backwards at ease and thats what I want, it even keeps up with the neighbors Revo 3.3 for short races. Is the 250-260 range ok? I run powermaster 30% as I do in my Jato. My Jato runs great at 260-275 but I know traxxas motors run a little hotter. I know I should just tune for power and ignore temps but want a guideline I guess. I would think the 250-260 is fine just want a few opinions. All I do is bash around the yard and road with the maxx. This motor isn't expensive but I dont want to burn it up in a few gallons. I have a hole cut in the windshield and the rear of the truck for air flow. I get these temps when in the yard but it is usually a little cooler after a good run on the road. Also I know a lot will say pay attention to the smoke trail but this powermaster fuel seems to smoke less than most. Plus I have always liked powermaster in planes and a gallon of 30% car blend is only 28.99 and my Jato and the SH 18 loves it. Thanks for any help.
