Motor Question
 

The first time I used my Microsizer with the stock 2.2 and 1 full charge, it was fast. Now, using it once daily for 2 weeks, the motor downgraded to at least a 2.0. Is the motor's fast lifespan up, or is it the battery?

Have you tried cleaning your bit out? Make sure there are no hairs wrapped around the axle and such.

Yes, I've done that. Should I cycle the battery a few times?

Take it apart further and you will find hair wrapped around the pinion gear of the motor.

Also, unfortunately, hair gets into the front wheels too.

I found that the cleaning brushes from electric razors are pretty good at teasing hairs out of them.
Tweezers too.

As long as you run the battery down every time and charge it all the way up, there shouldn't be any ned for cycling the battery.

I agree with strider_mt2k, the batteries are designed to last 650+ hrs, I can't imagine one losing charge in just 14. Although draining it completely/recharging never hurts.

Sorry, that's what I meant when I said "cycle".

here the most common solution. Replace the controller batteries with good ones.

yea, if you controller doesnt have enuff energy to even give to the car, then it wont have as much, so your car would be slower:)
