I'll say it again. I've had nothing but good luck using these motors. I've ran everything from the 21.5 I'm not M05 Pro all the way to a 7.5 I have bolted in my Open 2wd SCT with no issues at all. Always as fast and most of the time faster and for 1/4 of the cost!

a clip on is fine. i run the WTF fan from the awesomatix guys. good fan. any of the fans are good. but get one that you can wire direct to your esc to get 7.4v. so when youplug the battery in the fan is on regardles if the car is on or not. you can race...finish put the car on bench and leave plugged in and the fan will cool down your motor.

Well I just got done running my 21.5 with a 4.17 FDR and my temps were at 130 after the race with no fan! I wasn't getting pulled in the straights last time and took .4 seconds off my average lap time. Going 3.8 FDR next race! Definitely pleased with the motors performance. Just as everyone else has said these aren't really any slower than anything else out there.

is your track fairly small? whats the straight length? i would gear fo the motor to top out just at the end of the straight. then it should be fairly quick in the infield.

I really don't know what's considered large or small but I am definitely at full speed and have the motor topped out about 1/4 of the way in to the straight with the 4.17 gearing.

gear it up some more. go to a 3.8. it should top out at about 3/4 to 7/8th of the straight. your speed will go up alot and lap times will improve also. its under geared. but...add a fan for sure. a cooler motor means less resistance and more power! Heat makes resistance thus limiting power flow in the motor. keep em cool as you can. good luck. i love these motors.

This also exlaines the "noisy" low speed running.
I got the silver can 10.5 Trackstars and they do the same at low speed.
When running at high speed it is gone.

Glad to report that my 10.5 works great in my Buggy, speed is alright and its reliable so far.

3.9 isn't enough gear for boosted. Start around 6:1 and add boost to your liking. You may be able to go lower but I would start there for boosted and work my way down if I was running 21.5.

not sure about boost. we only run blinky. so what he is suggesting might get you there.

Im currently running in my F1 a thunder power 21.5t with 79/19 gearing for a small indoor carpet track (lap record is in the 10sec range but we fade to mid 11s near the end) Finished 3rd in the championship but the motor is a year old and we run 100 lap and 50 lap races (100 lap races are 18-20mins long) so it has some time on it now and is loosing some power.

If i got the trackstar 21.5t what would you go timing wise and gearing for a starting point. We run blinky and foam tires.

Thanks

run the timing to the max on positive side (this equates to about 35 degrees of timing) and run it at about a 3.8 to 4.0 for your smaller track. if your tp motor was at 4.15 then a trackstar you can put a little bit more gear to it since it does not have as much timing built into them. they have alot of torque so you can gear them up a bit more. try a 3.8 to 3.9 to start and them monitor temps. try to stay under 130. thats my goal with these. they run the best under 130 degrees.
