Question
Motor options for HPI Micro RS4

Hi everyone,

I have a Micro RS4 with Team Orion Flash ESC and stock motor.

I would like to upgrade, but I want to switch only the motor. What would be some good value motor choices to work with this ESC?

It would be nice to find something on ebay or on some international website, as I am not from the US but I am new to the cars section and I don't know what type of motor I am looking for.

Team orion Elite micro modified motor. It's a direct drop in with stock motor mount plate.
A bit pricey though ...

the stock motor is a 180 size and i have personaly put as large as a 380 in one but went brushless because got tired of not getting the results from the small upgrade motors .
make sure you up grade the drive shafts before up grading to much .

Can you fit a 2040 brushless in there? You can get some pretty cheap motor/esc combos in that size online, like $40-$50 total.

I was wrong on the pricing, they're even cheaper than I thought!

i took the losi excelorin brushess out of my mini SCT and put it in my MRS4, just had to shave some plastic off a post to clear the rear of the motor and enlarge/slot the lower mounting hole for the motor screw. already managed within the first 30 seconds to strip the drive tabs off the front diff carrier that fit in to the front pulley.
