what will be the difference in wheel speed 1800kv vs 27t?

[idaho]

So I am trying to figure out my gearing before buy it, what will be the difference in wheelspeed be between my tacon 3660 1800kv brushless and the stock axial 27t brushed motor? And yes I know the tacon isn't the best motor ever but the price was right and it will be my first waterproofing attempt.

What battery are you gonna use?
1] voltage
2] C rating incase using lipo

This should also help....R/C Calculations

You will need this motor info to fill in the calculator

id imagine that they are about the same amount of tq. but the brushless has more rpm. You are buying a 550 size motor, so it will move the truck easily. You could look for a 3650 size can, that will be a 540 size motor. But tacon isn't bad, cheap yes. And I hear the glue debonds at high temps. other then that I hear people like them in the short course community. But typically non-sensored motors are pretty waterproof to begin with. Don't use a higher than 80amp esc with them (imo) I use a hobbywing wp60 its been great, fully submerged like 2 times and no problems. Its fully programmable and I only use nano-tech 6000mah 25c 2s lipo

Tacon 3660-540L-14T Brushless Motor 1800KV for 1/10 Car Trucks

For now I will be using a 2s 20c 5000mah 7.4v lipo

I got a hobbywing crawler 35a esc in the deal so that's what I will be running with it, I'm using this as a test for my waterproofing before I spend the real money.

Thank you for the calculators wings of fire, that was a big help.

More likely the opposite!

The BL motor will have lots of torque compared to the brushed motor, but run slightly slower at no load.
With a larger pinion the wheel speed should be substantially faster while you still have more torque at the wheels and a cooler motor.
