There is four motors, four speed controls, and two batteries in the picture. I purchased the motors looking for a light option as I am trying to keep this quad reasonably light. The prop-saver part of the motor is smaller than I expected, so we will see if that becomes a problem. The mounting holes are too small for #2-56 screws, so I will need to make them slightly bigger. The batteries are 1800mAh 3S rated for 40c-50c discharge rate. That much current is way more than I need for these motors, but I may want to use these for other motors or other projects where the current will be useful.
Getting ready to ream the motor mounting holes and drill holes in the carbon fiber motor mount sticks.
Reaming the motor mounting hole to increase them from 0.080" (2mm) to 0.095" (2.4mm). This should allow a little extra room to take into account the imperfections in the hole spacing on the motor and in the mount stick.
That's all for today.
