because some motors are designed to handle 2 cells, and other motors are designed to handle 2 or 3 cells or even more. I burnt one of these motors out on a 3 cell. I thought it was just bad luck, so used my second one (i bought 3 of these) and that quickly burnt out too. I have claimed my money back before on a different motor, and it is just not worth all t e hassle of having to upload pictures and a video, then send it off for testing, bla bla bla. So i wasted 2 very good motors through bad advertising!
Anthony, You burned up your two motors because your prop or pitch was too much for a 3 cell. For example , if you are using a 2 cell pack and an 8x6 prop it might pull 8 amps at full power but if you decided to use a 3 cell pack with the same prop you will go over the 8 amp limit for what this motor is rated therefore burning it up. So you will either need to reduce the pitch (8x6 to 8x4) or go with a smaller diameter prop (8x6 to 7x6).
As Miguel mentioned you must have a watt meter to know what amps you are drawing that way you can know what size prop and battery will work best for the most power without burning the motor up. You might be able to get away with more cells with the biggest prop with out burning up the motor but that usually means because you limit full power to 2-5 second burst here or there to bail you out of trouble when you need it.
Hi, Donna. With this motor its very easy. As you can see on picture 3, there are two little black bolts on top of the motor. Just put the propeller on top and run a rubber ring across the two bolts. Happy flying.
