So all these experts what do you suggest 9/86 gearing? Let us users who "abuse their motors" in on this big secret!
I think the best thing to do is make sure you give it a good break in before you start running it hard. I know around here we have been trying different break in methods to try to make sure we get a good life out of them.
One of the popular ones is to run the motor in a cup of cold tap water at 4-5 volts for 40-50 minutes and change the water out every 10 minutes or so as it gets warm. Or just throw a couple ice cubes in there to keep it cool.
The second thing is motor temp. These things don't like a lot of excessive heat. I only race mine so it's 6 minutes at a time for me plus a couple warmup laps. At the end of my race the motor comes off at about 110 degrees. I am consistently in the top 3 in the A-main. Just because your motor is running hot doesn't mean you are over geared. An under geared motor can cause excessive heat build up as well.
The third is current draw on the motor. The brush springs in these motors don't like current spikes. It heats them up and then they lose tension. To help with this and motor temps. Try getting on the throttle smooth and slow rather than just ripping it back. I promise if you learn to drive like this it will make you better and faster. If you get the truck in a stuck situation like up against a pipe wait for the marshal rather than trying to climb over it. Trying to climb over it creates a huge current draw on the motor. In sharp corners try to keep the truck rolling at all times. It takes far less current (and is easier on the motor) to get the truck up to speed from a roll than it does a dead stop.
Now all this said these motors are overall still junk but the above will help. I just had one that the front bushing wore out for some reason after 4 weekends of racing which comes to a total of 20 runs. At the cost of a new motor that is only 1 dollar per run.
