i sucessfully made a shaft for my mini x that allows you to use different motors. all i need to do is make the motor mount. but before i do this i need to know what type of motor to use in it. should i stick to the 130 mini z type motors or should i go with the 180 motors? motor mounting for the 180 type motors would be alot simpler than for the 130 type. let me know what you think.
