FAB 4 Racing

What is the difference between kv and turns in an electric motor? Some electric motors are specified by "turns", which I know, and some are specified by kv. How do the kv relate to the turns? Thanks.

well what your looking at (the motors specified by kv's) are uncensored motors. they arent the best racing motors but make a great bashing motor.

coorect me if Im wrong


Brushless motors are given a Kv rating, which is RPM per volt, that lets you determine how fast that motor will rotate with a given voltage supplied to it.

so determining what turn a brushless motor is you have to know the KV rating of that motor and other motors like the novak motors you have a 10.5 turn brushless motor which is a 4300 KV motor and a 8.5 turn brushless motor is equal to 5800 KV

and a 10.5 motor = to a 19 turn brushed motor
8.5=15-16 turn brushed
7.5=13-14 turn brushed
and so on and so forth




I hope this helps some

The higher the KV rating, usually...the lower amount of turns

Not necessarily...

The very first Novak Brushless motors, were rated by KV. They were the 4300, and the 5800. We now know that the 4300KV Novak motor is a 10.5 turn motor, and the 5800 KV motor is a 8.5 turn motor.

I am not sure if there is a way to calculate KV rating into turns, but, I do know that the term KV=RPM's per volt. So, if we were to use a 4300KV motor as an example, we would see an equation something like this...

4300 x 7.4 = 31,820

That should be the maximum RPM that a 10.5 turn motor can achieve if using a 7.4 volt 2s lipo pack.

So, if you know what the maximum RPM of a certain motor is, you should be able to reasonably deduct with that formula what turn(or at least get close)any motor is.

Is anyone running their TC5 on carpeted oval??? I am running a TC5 with a 13.5 and a Orion 3800 Lipo. I am looking for a basic set up for on the oval. It is a midsized track with med-high bite carpet. I am pretty much just running the box stock set up for now. ANY help would be great.

This would about sum up the results of ME doing anyone's taxes.

Another Tuesday and another snow storm. I think that makes 3 weeks in a row. But we still had a bunch of troopers that made it out.

Thanks to the Billies for joining us and it was good to see Michelle race after 2 years.

also to Jim and Cody Bailey for driving from Rockford.

Here are the results and we will see everyone next Tuesday or this Saturday.

Well. so much for the results tonight. we just bought a new computer today and when I upload the files it says the file is to big... so I will ask Doug for some help tomorrow.

good night.

Just did Marty. Two Trackside gift certificates. Doesnt get any better than that!

Had fun watching the kids race last night. Michelle did good too. Right in the mid pack for most of the time. Glad I wasnt racing her. Electronic problem dropped her back in the main.

Thanks to Scotty for making us welcome on a wintery night. I couldnt believe he remembered where she was at college after three years. Incredible. Great place to race.

Merry Christmas to all at Trackside! See ya at the track. Chuck

ddint see it on your webpage but to happen to do a spec slash class just looking for somewhere to race (stock class only) thanks Rob
