Our CNC facility will be closed for Chinese New Year national holidays. Orders placed and designs uploaded after January 10th will be delayed until our facility re-opens on Feb 8th. Sorry for the inconvenience and thanks for your understanding.
This is a modified arm for the SCX-200 which turns the frame into a 220mm stretched X. The area around the motor has been beefed up, to prevent breakage (this is the common location), and the arm has been widened from 14 to 15mm to cope with the additional length of the arm.
