Brushless maintenance intervals?
 

Put a 5400kv RC Gear shop from Towers in my P2de last summer. It has only been oiled on the rear end a couple times, and has roughly 40 hard runs, and feels like its power is a little low compared to when newer.

I am used to brush from many years ago, but when deciding to get back into the hobby last summer after a 10 year break, I decided it was time for brushless.

What do you guys recommend for maintenance? I understand brushed motors and rebuilt my bash motor every 5 batteries, and my race motor after every run or night.

Except for a small drop of oil to the bearings now and then, there's actually not much to do. There's no commutator and no brushes, so the two things, requiring the most maintenance back then, are gone.

I've got a number of vehicle going into their 6 years. Most I've ever done is use air compressor to blow off motor. Still run same as new.
Might be just used to speed now. It happens.

It may not be motor that seems to be down on power...could be your batteries too.

Especially running outdoor, you will be surprised how much "dirt" is inside the motor, once you take it apart, especially the motors we use in 1/10 TC's that have very large venting holes in the can.

Also, the oiling of the bearings, if you do it while the motor is assembled, and you just want to apply a drop of oil in the front bearing, be sure you have cleaned it as much as you can, otherwise you will only get dirt in the bearing with the oil and that will significantly reduce the life of the bearing.

Going to take it apart tonight, but first we're going to measure off about 10 yards and grab a stop watch to measure how fast it goes now, and then after a good cleaning. I want to see how much of (if any) difference it can make.

It is in constant dirt, water, and in general mud. Sure something has gotten inside.

only maintenance I feel the bearings, Sensor board and the rotor. Rotor being a permanent magnet, what kills the magnet is heat. So watch how you gear it and set your boost & turbo correctly. Running in dirt maybe period you want to make. Indoor carpet maybe once a year. Make you own schedule..

Tried taking the motor apart anyways yesterday, and found one of the crews were horribly stripped from the manufacture.

Unable to gain access, I decided to blow some air through the motor while two of three rear screws are removed allowing air to pass through with little restriction. This seemed to help and felt less gritty. Then applied some fresh lube and put the two good screws back in.

Everything worked out fine and got some timed speed runs. However, after a couple battery packs, I decided to put the stock motor back in for a while because my buddies have been driving this one and with the 5400kv plugged in, it was to powerful for them.
