160 deg F/8 min main

If i go hotter than 170 after a full pack, i start looking at changing gears, or timing.

Depending on the motor.. Novak says 160-175 max for a Ballistic... I had an LRP X-12 7.5 in my Lazer FS 4wd that would normally see 180-185 after a good run.. Geared properly.. It was normal.. However, If a Novak Ballistic or Orion Vortex Pro got that hot.. That's a different story

After 175 the ballistics start to slow down a bit. Its pretty noticeable on the track. All of a sudden, the triple you were making is all of a sudden being cased on the middle jump...

Generally I try to stay below 70-75°.

You might want to consider the season you are racing on, depending on that you can find an ideal temp now but within few weeks ( northern emisphere ) you will have to gentle the stuff a bit dealing with summer 35-40° daily routines.

i was running around 180 on my traxxas slash and thought i needed a gear change , but then i but a on board factory fan on it and now running cooler and longer times. i also throw a seperate fan on it in the pits while i am on down time. this is just to cool it down quicker so i can get back out on the track faster, i hate sittin on my ass when im paying for track time.

Careful though. That extra time could save paying for an extra motor.

180 is pretty high. If the fan is keeping it down that's good though.

++++ on previous post. Below 170 degrees on most motors will keep you in the safe zone.

Castle Creation motors generally can handle higher temps than others. I was recently told by Castle tech support that 200-220 F on their 3800kv 4 pole SCT motor (which I own) Is fine.
