1. All boards, speed sensor, charging port from premier csx Sd-80. Just pulled them and everything works. $150 obo not sure the value on these. Charging port is round. I believe this is a 9 volt.
2. All boards from Railking RS27. Note did not work when tried Perhaps sound board is fine. I just don’t know. The original battery over discharged. $35 obo.
Might consider partial trade for MTH premier motors
