    RE16 - Continuous Rotation Modification

    Originally posted by FTC8688
    Are we able to modify a 90 or 180 degree servo to make it continuous rotation servo? Specifically the Hi-Tec Servo Model HS-485HB which list Specifications as 360 degree Modifiable. http://www.andymark.com/product-p/am-2543.htm
    A: Because the modification involves changing or modifying the gears and does not involve the electronics or wiring this modification is allowed.

    RE15 - Removing Encoder

    Are we allowed to remove the encoder on the Andymark NeverRest Series? (AM-2964, AM-2964a, AM-3102, AM-3103, AM-3104)

    We just need to shorten the overall length.

    Thank you!
    A: Yes, teams may remove the encoder from the NeverRest motors.

    RE09- Changing motor gearboxes

    Originally posted by FTC11639
    The rules state that legal motors include the am-3102 motor (20:1 gearbox), the am-3103 motor (60:1 gearbox), and the am-3104 motor which is a motor with no gearbox. So, removing the gearbox and changing gear ratio is similar to using an am-3104 with a custom gearbox (hence, not modifying the motor). Is this gearbox modification legal?
    A: Yes, this is legal.

    RE15 - Servo Modification

    Hi, we'd like to upgrade the karbonite gears in our sail winch quarter scale servos to metal gears. There is no direct replacement and slight modifications are necessary as described here. http://ftcforum.usfirst.org/showthre...l-Gear-Upgrade. Is this modification/replacement allowed as described? Thank you
    A: Yes, teams may replace the gears in their servos with metal gears.
