Yes...you guys are not the first...I have 2 ended up the same and thought that was designed that way. It was really fustrated cause the heatsink ended up blocking the speedo or receiver cause I did not aimmed the alignment correctly and I was ended up using the brush motor.

I am glad I saw this thread...and I will contact NOVAK and see what other way I can do to remove those heatsink or anyway I can rotate the heatsink. I really thought it was designed that way....one of the motor I cannot even close the end(front) bell....

I was told 13.5 does not required the sintered rotor cause the sintered rotor does reduce heat....13.5 considered stock motor, I don't think it will ever have overheat problem unless you are gear it to the MARS. It is a good option if you are running 4.5 mod motors along with the heatsink to reduce heat.....but of course, cooler motor (no matter what turns) is always better and faster.

What can you expect by switching the 13.5 to Sintered? or Can it be a tuning option???

wow no heatsink!

You will be able to run the motor to 200 deg F with no harm (with the blue sensor wire pulled) so you will be able to gear up a ton. It will be way faster than with the bonded rotor. We have a guy running one in a sedan geared 4.9:1 final drive

The 1/12th guys can't fit a big enough pinion with an 88 spur to gear it right.

You may have to buy bigger pinions.

I have a few 78 tooth spurs... I'm curently running 85/34.... I could probably go up more, but why??? My track is real tight...

Be realiztic.......40/85, is that equal to 19T brush motor speed ...LOL

do you have to run the 13.5 on the gtb, or can you run it on the ss and ss+? also, what differences would it make running it on the different escs, that is, if its possible? would running it on the gtb actually make it faster? and would running it on the ss+ make it faster than the ss? actually, whats the differences between the ss and ss+? i have an ss+ and my 2 other friends have ss'.

It should run on the SS or SS+ esc. There should not be a large difference between the two. I do believe running the 13.5 on a GTB or Sphere might be a difference. It was fairly large on my 5800 when I moved up to a GTB. It may not be as pronounced on the ss+ do to less capabilites of the motor. It would be interesting if people have noticed any difference in the 4300 between the ss line and the GTB line.

What's this talk of pulling the blue wire? What does it actually accomplish?

Blue Sensor Wires = motor thermal sensor to shutdown ( said some people ).

Pulling the Blue wire is taking away the temp sensor, without the sensor you can run your motor hotter without possibility of thermaling but by doing this the motor is not going to be roar legal. But who care if your only running at a club level.

hey guys wondering if any of you have had any problems with the 13.5

our first test was last night at our club race we had 3 people testing the brushless in 1/10 stock. On the very first run with the new system, when accelerating I noticed the car would hesitate/bog down from a standing start and coming out of slow corners. But once it got up to speed no problems until the next slow corner. After completely checking the car from belts to bearings, cvd’s, ect. I realized it could be the motor. I put a new one in and had no problems. Not sure what it could be? Another guy had the same problems with his brushless after 7 runs on the motor, temperature never exceeded 180 degrees on any run and he ended up blowing the motor. Not sure if they were a bad batch of motors or what, but feel if these things are very temp. sensitive then how are the newbies going to feel if they keep blowing up these things? What are you guys finding regarding max temps? Has anyone blown up these things yet? I did notice during the main around the 4 min mark, I started to have a little power fade. When the main was done I temped the unit and I got a reading of 190 degrees all my previous runs were around 145 degrees with changing nothing to the car. I do like the idea of brushless and found that it was nice to have a consistent motor for 5 min. even though you need to gear higher. Nice to have the best of both worlds a torque motor with the rpm’s to go with it if geared correctly. I think brushless stock will only increase the numbers and attract new people to the r/c stock scene once the initial problems are resolved. Please let me know what you guys are finding out there. What temps should they stay under ect……..

all the best

I've never heard of someone frying a 13.5. Some of those temps are really high. What kind of range were you guys gearing at? The highest I've been able to get my 13.5 is about 145~150 deg. Most of the time I come off the track about 125~130.
