Kraton Replacement motor for Kraton Blx

[Duggin]

Its time to replace the stock 2050kv motor in my Blx. The shaft is lose in bearing. I’m happy with the power of this motor and not looking for insane speeds. I’m wondering if there is an upgrade in the same size can. I want to be able to use the motor fans I have.

The biggest problem with upgrading the motor is that the esc is already near its limit with the stock motor. If you want to stick with the stock esc I would just try to find a 4274 2000-2200kv motor.

I’m not completely against upgrading the esc to something more efficient. Not looking for insane speed but more run time would be a bonus.

Changing the esc or motor will not give you more run time, unless the current ones are faulty. Larger batteries can but only up to a point as the weight of the battery will start to negate the increase in capacity.

Will this work? not much choice out there. I was looking at the hobbystar 4092 1730kv but nowhere to be found

I have 1 and didn't have much luck with it.

This was after about 5 minutes of running.

Is that the Hobby store or the leopard? I have dual fans on my current motor the hottest it ever gets is 150° and that’s on a 90° day. Typically I’m running about 125 to 130.

My Leopard is way hotter than other motors too. I’m putting a dual 40mm setup on it now.

The Leopard on a 70* day. And do note the Leopard only has M3 holes whereas the stock motor uses M4 screws.
I replaced it with a Hobbywing 4985 1650kv motor and without a fan the max temp I have recorded was about 160* on a 90* day with the same gearing.

I just realized that is a different can on the Amazon link than the one I bought. I have the 4282 1680kv https://www.rcjuice.com/motor-esc/l...brushless-sensorless-motor-for-1-8-scale.html

Easy enough to drill and tap to 4mm. The original 4074 hit a 190 without fans.
From what I understand is the first two numbers denote the can diameter and the second is the length. Longer cans produce more torque but seem lower rpm.

Yeah that's what I did to mine was drilled and tapped the front plate for the motor. Yes the first 2 digits are the diameter and the last 2 are the length. And I think torque goes up with the diameter as well but I could be wrong about that.

Like I said I’d like to keep The diameter the same so I use my existing fan setup.
Sounds like the longer cans run cooler?

What motor are you running?

I run the rocket 4092 1650kv 17t on stock esc, and so far its has been great. Dual fans and no heat issues yet. I will get the max6 at some point, and then gear it higher.

I finally pulled the trigger on Leopard Lbps 4274 1800kv
