Well, not all traxxas engines will operate the best at the same exact temps, as no two engines are going to be alike in terms of the settings needed to get them to run properly. A normal operating range for the 3.3 I would say should be 230-270(give or take). Anything more than 270, and that getting a little too close to comfort; anything less than around 230 or so, and there is a chance the piston/sleeve/rod wont have a chance to properly "seat" themselves or get up to proper operating temp....

RE: tmaxx HSN
If you are breaking in, richen the high-speed, and turn up the idle.
Sometimes the stock settings for break-in are not right for your part of the world.
After break-in lean it out. Keep the low-speed alittle on the rich side.
You want the motor to idle for 10 secounds or so before it loads up and stalls.
If it idles and never loads up and dies it is to lean on the low speed.
