information on kb45 motors?

It was frickin awesome till it died.

Was it cogging at all?

That's a bummer. Do you think you got a dud?

Some people have had luck with the KB's, some haven't.

I'm hoping to be one of the ones that do.

I think we'll start with 5S and closely watch temps. The Castle Blower would be a good addition, but I don't think there's room. LOL

I could drop back to a 46 tooth spur. That might help temps also.

We'll see how it does.

It's pretty cold out, so maybe it won't go poof.

No cogging whatsoever. The smallest blip of the throttle ended in a backflip on grass. Throttle control was paramount!

I was just dumb about it. After 1 min of running I felt the motor and it wasn't too hot. I should have been watching temps better. Then I handed the controller to my son and told him to give 'er hell. He's a natural behind the remote. I didn't check temps again and it just gave out.

I had read that you really needed to load the motor and the only pinion I had resulted in the formentioned 60mph gearing, I just went with it. My own stupidity.

I hope you have good luck with yours. It was insane power until it died.

Hmm, try overgearing a neu next time. You think the kb has power... I had a 1521 6s rig geared for 60, broke stuff, had fun, motor is fine. Damn 250 dollar motors are gangsta....

This is one of the motors I got from you Linc.

Well I never actually ran a kb motor... They just sat in the boxes.

Edit, never ran a XL kb, I did run 2 of the L can motors in my gtp. I never had heat issues there, geared for 50mph on 4s lipo.

i have the 1200kv xl sitting in a box now awaiting a nice heavy project one day.

Hi Tash. What are you calling a "heavy project"?

The 6mm id motor pinion I'm using is stainless. Are they any good?

It snowed here before I got a chance to really test this out.

Just a few short bursts on my cleaned off drive, shows a little cogging at startup/crawling speeds. But WOT results in a quick spin around. It was kinda wet out.

I'm thinking about replacing the 40 tooth spur with a 46 tooth version.

25/40 changed to 25/46

Short tests were done on 5S. In about 10 minutes, the motor got up to around 130 degrees.

something that needs all that torque to run. i had an l can in a ext flm emax and it was plenty, so i'm thinking this will do in something larger if needed.

The weather finally permitted some testing and testing I did!.

I set the timing to low thinking that might help tame temps. Hmmm............maybe it helped. At the end of the run, the motor was probably 160 degrees or so. About 2 or 3 seconds of fingertip action is all I wanted. LOL

That run should have been recorded for Beat Your Truck.com or something.

On 5S it's crazy! I couldn't grab WOT for more than 1/2 a second at any time. 40mph backflips are kinda hard on a truck.

We have carnage!

The rear wing mount broke off.

This truck really looks funny running around with half of it's butt missing. LOL

Incredible Power though! I'll try it again after I get some parts in. LOL

Maybe drop the timing to lowest. It seemed to like the lesser timing with the tall gears. It starts up better and does low speed better.

Overall, I'm very impressed with the Power output!
