Pololu 130 Motors for Stryfe/Rayven/Barricade/Stockade

Got my shipment of Pololu Solarbotics RM2 130 size motors today, and the results are impressive.

Popped a pair in my Stryfe masterkey (NO PLASTIDIP - meaning that they have the potential to go even further when I add some to the flywheels), and they were humming along nicely. On top of that, even running a little over their rated voltage, I didn't smell any burning, even when holding it revved for a minute, nor did it sound like a chainsaw like the stock motors.

At stock voltage (6v on alkaline AAs), elites were hitting about 40 feet flat (single fire or rapid fire).

At ~9v on 2 Trustfires and 2 nearly drained alkaline AAs, elites were hitting 70 feet flat consistently, and 65 feet during rapid fire.

This testing was done with a retaliator barrel ON (meaning it cut some range), the chokes reattached to the new motors, the flywheels have yet to be plastidip coated (for better dart grip), and using the same 4 elite darts every test.

TL;DR: new motors that can run on 2 Trustfires, hitting the same range as stock motors and 4 Trustfires, without the burning smell or chainsaw sound.

A pair of these motors (installed) will cost $10 in either the Stryfe, Rayven, Barricade, and eventually the Stockade.

I'll try to get a side by side comparison video of stock motors vs. new motors later this week.early next week.

  1. Cool site you got here. I got a question for you hopefully you can answer. I did this mod with the Solarbotics RM2 motors, everything was working fine at the last war, I tested it lastnight and now only one motor spins. I havent re-installed the voltage normalizers on the motors when i did the mod. Do you think this could be the problem? Ive test each motor seperately and they both work. Any help would be deeply appreciate it.

    1. No, those chokes not being on wouldn't cause a motor to not spin. If both motors are still working independently when tested, then it sounds like you may just have a faulty connection somewhere between where the circuit enters the motors and where it leaves, probably just a bad solder connection (or the solder may have melted from the heat produced by high current, that's happened to me before).

  2. Can you put 3 trustfires through the motors without worry?

    1. 3 trustfires (+1 dummy cell) have been tested and you can smell burning motor after a few seconds. These motors are only rated for 9v maximum (they could handle 10v but would obviously have a shorter lifespan), and 3 trustfires would equal anywhere from 11.1v (3.7*3) to 12.6v (4.2*3), both of which are above the safe operating capacity for these motors.

  3. Question?? Any other motors that compare to the Rm2 solarbotics but with carbin brushes??

    1. if you want an rm2 with carbon brushrs, get another set of any other 130 size motor with carbon brushes, and swap brushsets
