Like this one in the link... http://www.tamiyausa.com/product/ite...oduct-id=53101
That's not what I mean. Yes, the 04 module pinions will mesh correctly with the 04 module spur, but I don't think you'll be able to move the motor forward enough in the motor mount for the pinion and spur gear to mesh.

oh... Really??? So what then should the gearing be??? Pinion and spur???

The upper 20's looks to be about the limit before you run out of space in the motor mount.

I used a 18 tooth 06 module pinion with the 70 tooth spur on my TA05R with my old Novak 5.5R without a sintered rotor for a FDR of 8.75. I used the 06 module because the bigger teeth can mesh whereas the smaller 04 module teeth wouldn't when the motor was moved as far as possible forward. The motor would get pretty hot after 5 minutes of racing, but I only made it thermal twice of the many times I ran it. I haven't ran the 5.5R since I recently put a sintered rotor in there, but I am sure a lower FDR of about 8.0 should be okay since the sintered rotor upgrade keeps my Novak 13.5 much cooler than when it had the bonded rotor. I used to run ~5.7 FDR with the 13.5 and a bonded rotor, now I run a ~4.8 FDR without getting close to overheating even after 15 minutes of running.

If I were you, I'd set my car up with the highest FDR possible without changing the spur or other gears and then see how hot the motor and ESC it gets. From there, you'll have to do whatever is necessary to run the desired FDR without making the ESC or motor thermal.

But a 13.5R is equivalent to 19t??? so meaning to say it is okay for you to use that kind of FDR but for a 3.5R it would heat up so much... Am I right??? I'm confused now...

13.5 is equivalent to 27T stock while 10.5 is equivalent to 19T. This is based on novak's motor. cheers.

13.5 Pro is said to be close to a fast 23 turn brushed motor. The 10.5 Pro is closer to a 19 turn brushed motor.

Anyway, what I was saying is that I ran a FDR lower than what is recommended by Novak for the 5.5R (9.0 FDR) with a bonded rotor and didn't really have to worry about overheating. With a sintered rotor, you need to run a lower FDR to make the most of it because it has so much low end punch and to take advantage over the superior heat tolerance characteristics of the rotor. However, I've never tried using the 3.5R before, so I am just telling you the info I have to help you get it running.

Take Novak's gearing recommendations with a grain of salt since those gear ratios recommended by them are on the safe side and because those ratios are probably meant for brushless motors with bonded rotors (my old manual that came with my 5.5R with a bonded rotor recommends the same gear ratios you mentioned). Therefore, since the TA05MS motor mount will not allow you to run a gear ratio higher than around 8.75, try that and see how hot the ESC and motor gets; it just might be safe to run a FDR of around 9.0 or lower with the 3.5R on 6 cells.

And we use 8.5 which is equivalent to 17t

Hey HI_808, guess what, the .04 21 pinion just fits perfectly in my 05ms... with a 105t .04 spur... Now I have a 11.25 FDR... And guess what, I could still put the 20t .04 pinion to get a more lower FDR...

And I am very much happier just getting the FDR I wanted...

Sorry Xanavi, I mistakenly assumed that the little space I had left between the front side of the motor and the motor mount when using a 29 tooth pinion was not enough to use so much of a smaller pinion. Following reading what you posted, I tried putting a 23 tooth pinion in my 05MS and it fits just fine. Also, now that I did that, I realize that I can probably easily go higher than 8.75 FDR in the 05R if you change the screws that hold the motor to the motor mount.

Once you get your MS running with the 3.5R, please let me know how low of a FDR you can use without overheating.

Hahaha... No problem sir... Will let it rip tomorrow morning at the local track here in the philippines (that is on of the biggest on road race track that was before a off road track...)

Will let you know as soon as possible sir...

Hey, I forgot to ask, how will I know if my run is enough tomorrow? How many laps should I make before checking the motors temp???

Check the Novak brushless thread. Unless you have some kind of thermometer, you'll just have to "feel" the motor and ESC.

Hey, guess what... I ran my BL System with an 11.25 FDR and it got a 49.9 degree Celsius or 122 something Fahrenheit... I didnt get a chance to test all of the FDR possible but I am thinking you should only lower the FDR to 10.8 because someone told me that his BL motor overheated because they were using a 10.45 FDR in a 3.5R BL motor... Why didn't get a chance? Because I decided to run 23t instead... Didn't have the battery(3700) to last in a 5 mins heat... Hahaha... Mybe next time...

Just want to share my experience with my 05ms yesterday's race. It is really a superb kit. I cannot say more about it but excellent kit (altough I havent tried the 415 or any other high end kits) but still, I love my 05ms compared to the kits that I have tried running with a 23t motor. Altough for me, its handling when using a 3.5R BL motor is average because of the cause of the one way unit. It is not suitable for a 3.5R or very low turn motors. It is better to use a direct drive or spool when using a 3.5R but still it is number 1 for me or 2nd from the top (If I think have tried the 415). I came in third for some technical problems with my controller and signal and with the driver (somewhat sleepy and havent slept that time). Kept flying (not most of the time) in the barriers of the track. And it is the first time I ran 23t and the kit.

Anyway, to shirten everything, it is the best kit (so far) that I have ever tried. Superb handling and balance. A+++
