Felony Motor kv question

[rub90]

Does spectrum make motor with a higher kv than 2050 thats compatible with 6s?

 

[LibertyMKiii]

Nope

You mean Hobbywing USA right?

Like the 4274 2250kv

Out of curiousity, why would you want a 6S motor with a higher KV?

 

[Dales396lt4]

If this is for the Felony and you need to overpower it, you can do as I did and put a Hobbywing Max6 g2 combo 4990 1650kv. in it.

If moving to a higher KV motor bear in mind that the motor may be rated for 6s, but the ESC can only handle 6s up to a certain KV threshold, and I think that the 2050 is already pretty close to that.
It’s pretty easy to roast an ESC running a motor that it can’t handle.

Check out TP for 6S motors with kv ratings higher than 2050. For example:

Not necessarily looking to do it. Just trying to understand motors and ESC better.

And this one!

80k rpm's! (for 10 seconds)
Diameter X Length (mm): 40 X 83

When talking about the motors there are 2 aspects to consider.

1. Can size. Going larger can help it shed more heat, but you need to understand that it can generate heat much faster than it can shed that heat.
(still usually requires fans)
2. KV translates to RPMs per volt. Most people bashing their 6s cars have found going lower KV helps it stay cool. Higher KV is usually only good for drag racing or speed running where you are running the car for 10 seconds or less.

The Max6 Hobbywing combo is very popular in 6s bashers because it does both #1 and #2 above. The can is larger and the kv is 1650.
You are still able to go faster than "stock" with this setup by adjusting the gearing.

Higher KV also demands more amperage from the ESC. Typically going higher KV on a ready to run ESC will just cause it to power cut.
One upgrade usually demands 2-3 others... Get the motor, now you will need the ESC, better connectors, and better lipos. With all the extra wattage flowing now you need better cooling. With the higher speed now you need a better radio and servo LOL

This one has been behaving well in a stretched typhon buggy thing on 6S (12lbs 'ish).
CASTLE 1515 SENSORED MOTOR - 2200KV

I never could, I had to run that motor on 4 cell.

The other factor would be your ambient temps, how you drive, and where you drive (Grass, dirt, sand, road etc...). For the Kraton 6s I can get my Max6 combo very hot in 5 mins because I push it at 100% the whole time.

 

[Garcbomber]

You'll find out quickly bashing 22V+ with any motor over 2000kV will create a tremendous amount of heat even faster.

Thanks man. That’s what I was actually looking highly appreciated. And what’s your take on cogging. What’s the main cause. I’ve been hearing different opinions on it? Some say gear down others says switch transmitter others say bigger motor?

Some motors cog more than others. I disagree with those who say transmitters have something to do with it. It’s caused by the ESC not knowing the position of the motor rotor at low speed. It’s a mix of the ESC and motor “talking” to one another. The problem is made worse the higher you gear it because the motor is turning more slowly at lower speeds and off the line.

+1 on what Dan said above. Nothing to do with the transmitter.

If the motor is cogging in a RTR configuration and gearing (40-60 mph gearing) usually that means the ESC is bad.
For a speed run car, cogging is normal because the pulse to get the car going just isn't quite enough and the ESC assumed it was.

I did run a giant motor (Leopard 5692) in a Typhon 6s with extreme gearing and didn't experience any cogging. So..... running a big motor with low KV helps.

Ok thank you. I will try and do that instead.

Yea I’m leaning towards getting a censored motors. From my understanding that would help.

You mean Hobbywing USA right?

Like the 4274 2250kv

Pretty much

If this is for the Felony and you need to overpower it, you can do as I did and put a Hobbywing Max6 g2 combo 4990 1650kv. in it.

How many miles/h are you getting?

And this one!

Thanks.

I put the Castle mmx8 and a 1515 2200kv in a stretched Buggy and it's better than the stock motor.
More power, bit more RPM's and its not been overheating. Running 3.3 difs, 50 spur and a 23 pinion.
Im just grass field bashing and running with it but im on throttle the whole time.

 

[Dales396lt4]

I’ve never really topped out my limitless. I’ve only made three runs with it. At just over 110 mph on 8S 32,39, gearing and 2,80 diffs. It made running 110 so easy and effortless. My goal was to be over 100 I made that goal in three runs first run was 97,99, 110. The road I was on was only 250 to 300 yards long, nowhere near long enough to really open it up and hold it wide-open for a second or two I can only get up to speed and then let off I still had to have time to slow it down. A sensor set up is so smooth, once you drive a sensor car. It’s hard to go back and drive one that isn’t censored. I’ve been slowly changing all of mine over. I still like the stock system but man it’s nice having a sensor system. As for my Felony, I have not been able to do a top speed run on it yet. It is geared for top speed having a 36/50 gearing however, it becomes kind of unstable up top. I had a hard time controlling the dissent or slowing the car down and keeping it under control, so I change the rear gears to match the front and went to 53, 100 tires, it’s a lot better but I also change the body to the Corvette. I haven’t got the side skirts for the Corvette body so I really don’t want to run it very fast afraid it might blow over.
