That is a very generous offer. Just for general note, we bought the 20:1 gearboxes and i replaced the screws with M3- 30 cap screws. I did have to turn the heads on them down a bit to get them to fit into the clearance holes but after that the snugged right up no problems. I Would recommend that if you haven't taken them apart yet make sure you do it with a proper sized Phillips screw driver, this will help prevent stripping until you can change the screws.


Some other assembly notes i have found through experience:

The spacing that you want from the pinion to the motor body is about 1/16 of an inch, making a spacer plate really helps with the assembly.

you can head the pinion to make it side on but after trying that pressing it is much easier.

when you press it on only support the motor on the shaft, bend the electrical leads out and hold it between the 2 ends of the shaft, this minimizes the chance of bending the shaft. I used a socket for a spacer.

If you have old FP motors lying around make sure they are no where near you when you are working. (good thing i bought extra pinion gears.)

If anyone needs help or advice please feel free to contact me. So far i am very impressed with these little gearboxes and i have a feeling i will be using them for years to come.
