Works great

My motor burned out in one of my 4x4 mega so I decided to upgrade it to brushless and now it is really fast and I would reccomened this to anyone who wants to uorgrade their brushed into brushless.

Bearing blew up, screws keep coming off

Performs great but has issues. The front bearing blew up on mine like everyone else, luckily I was able to just replace. However the screws holding the rear of the can on keep going missing. Standard m2 screws will fit but eventually the threads strip. Also when in an Arrma 3s, gunk will build up in the front bearing if you do not fix dirt being a...Read More

Spektrum if you are reading this please release a motor maintenance kit with a new rear cap and screws. Read Less

Front bearing is terrible and will burn up at low heat

I have 5 of these motors in various RCs. All 5 siezed up after only light duty use due to the rubber front bearing seal failing under moderate heat (Never exceeded 139 degrees according to telemetry). The rubber seal WILL melt and gum up the entire motor and possibly destroy it if you don't catch it right away. Once the bearings went out it also d...Read More

estroyed 2 of my drive gears due to the wobble of the shaft. I know of several others at my track and local hobby shop that have had the exact same bearing fail almost right away.

The good news: The motor can be easily repaired by cleaning the components and replacing the front shaft bearing but Spektrum should address this problem and use a higher quality bearing set. The motor itself is a beast. I have replaced all the bearings with metal sealed replacements and I have since had no issues. I highly recommend replacing the bearings in the motor before running it. Bearing info: I replaced with Fast Eddy bearings - 5x16x5 (625-ZZ) and 5x13x4 (695-ZZ) - about $20 will get you 10 of each bearing.

I'm a loyal Spektrum user and pretty comfortable wrenching on stuff but If you don't wanna mess with this problem, get a Hobbywing Motor. I have had no issues with either of mine and I run them pretty hard. Read Less

Q: Can you put Firma 3200Kv 4-Pole BL Motor, 3660 in a 1/10 SENTON 4WD V3 MEGA 550 Brushed Short Course Truck RTR ?

10/10/22

A: Yes, you can. You will need a new 5mm shaft pinion gear and a brushless ESC. You also will need a 2s or 3s LiPo battery.
