Everyone wants to know what RC platform you have. Since you bought a 2845 5900kv motor, maybe a Hobbywing QuicRun would be up your alley?

wltoy a959b

Got it. 1:18 buggy that comes with a 540-size motor. I don't know anything about wltoys but I'm going to guess, since it comes with a 1:10 size motor, its drivetrain is geared for 1:10 torque and any 1:18 size brushless motor you install will cog.

Keep the 120A ESC and replace the motor with something like this and it'll work. It'll be undriveable on 3S but it'll work!

That Wltoys RC is a bit strange if indeed you sure that platform comes with a 540 size motor. The "upgrade" motor does not look like a 540 size can in the pictures. Plus, I see a lot of 1/14 and 1/16 scale RCs using 28xx size motors. Interesting for a 1/18 scale RC to be cramming a larger motor in there.

I checked and double checked.

Looked up the replacement motor and found this

Reminds me of the 1/16 Mini-Revo based Slash 4x4 that came out years ago with a big ol 540 can strapped to it.

I agree. The brushless looks like a 28 can, stock looks like a 540.
I had a DeeRC 200e that had both these motor options too.
Each motor comes with different size pinions and motor mounts so they both fit the same spot.
I put a 3800kv promoto 3652 motor in mine and powered with 3s on occasion.
I wanted to see how quickly I could blow the spur off the driveshaft.
Very, in case you were wondering.

I think a modest brushless 3652 could work
But get too much weight and too much power with too much speed and things WILL start breaking.

I was wondering about that. Figured there had to be some secret sauce to make it work. Does the spur gear change? or is everything 48p?

Two spurs were availible for the DeeRC. Though I was able to get a metal 'upgrade' spur, It was the same size. It was a mod .06 spur with a 4.5mm(?) hex center. It wasn't very easy to upgrade.
Robinson sells the pinions. I sliced the motor mount with a dremel. Made it 'adjustable' where the stock part was not.

I never got far enough to get pinions dialed in anyways. I fried those gears QUICKLY!

car isn't mentioned but that looks like a combo for 1/16th-1/18th car, if so i recommend this: the combo (availability depends on where you live)

its not about the size i fit it all perfectly also i removed engine from rc and its still doing same thing when i touch the gear

You have been provided numerous recommendations here to get things sorted out. The size is important when selecting motors for RC cars. There is more to it than physically fitting the vehicle. All of which has been addressed here. Good luck buddy!

ya thanks for recomendations but why size matters when the engine is unattached
