Default Do you have to break-in all motors ?

I just bought a ORION RUSH 27x1 motor , do i have to run it in water to break it in ? Or can I just install it and start racing ?

Usually to break in modern electric motor we just run them at 2-3 volts for about 3-5 minutes. This is dry........ no water involved. It seats the brushes properly and will give you slightly better comm wear in the long run.

Not really. I would just go to the hobby store and get a few sub c battery cells or a cheap stick pack and only use 2 of the cells in it. charge it up and run your motor on that.

just get a battery bar and solder the pos and neg together. Now on the open ends where they arent connected, solder alligator clips to the cells.

dont cut the existing leads at the same time. Make separate cuts for the neg and pos leads. Otherwise you will short your stick pack with your cutting tool of choice made of metal.

depends on the typ of batteries you run .. 3300's and up run at least 10 minutes or longer if your messing around if your racing 5 min is all thats needed for your heats and mains ... practice little longer to get the layout and handling of your car situated ... Matched batteries usually have great run time ... also gearing your car correctly will affect run time .. I say try some new batteries and change the brushes when you cut the com .. you will notice a big diffrence ...

Same here, i might through it on a six cell pack to see if it is revving to the moon, but just run it, and MB has some screamin motors also.

I agree with him, I hate breaking in brushes I think its useless because if you build your motor right and everything like it should go then why do a break in ??? Like my dad has always told me when he rebuilds my brothers racing motor for his 7second RX-7 if the motor is build right then theres no need for breaking it in.

I dont agree

The point of breaking the motor in is to bed the brushes properly on the comm.
This reduces arcing, therefore less heat, more brush and comm life between rebuilds.
