un- marked out runner motors
 

Hi, I have two unmarked outruners brushless motors that were given to me but I don't know what its the power or the voltage that can be used for them I have the general measurements of both motors and maybe someone can guide me to find out what size they are one measures 62.5 mm wide (the can) and 53 mm long ( shaft wise) and the other one is 62mm wide and 52mm long the shaft sizes re respectably 1) 8mm and the second one is 11mm , if anyone can help me figure out the power and sizes for this motors it would be greatly appreciated thanks in advance.

Can you provide pictures? Is there any writing on the motors? What color are the motors? If they are gold they're probably AXI's.

Unfortunately one of the best performance definers of an electric motor are the wire size and windings and that is hidden within the motor. Without knowing the part number the can sizes are like have a can of Campbell's soup without a label. Good luck to you.

I have added pictures of the motors but I was told to compare the sizes with the measurements of the RXi motors and this ones come out to be about the size of a 1.2 and 1.4 motors which are good for about a 14 to 15 pound airplanes I'll just have to experiment with them and I think the prop sizes are in the 16 to 18" props , if any one can give me a more accurate answer it would be greatly appreciated .

I posted pictures of the motors , maybe you can recognize where or what they are , compared them to some RXi's and it looks like they are about the same size for their 1.20 to 1.40 motors , what o you think ?
