I purchased this radio new last year. It is the version with ratcheted throttle. It includes an AR6200 receiver and AR6100 receiver. Both have servo extentions and have been placed in a plastic box sealed with Marine Goop then liquid electrical tape. The 6200's second receiver has been protected with three coats of tool dip, and the main receiver box has a packet of silica gel for condensation control. I didn't have roon for the silica can in the box for the 6100, but drilling a hole and dropping in a few grains of uncooked rice was suggested by Phil A. The servo extentions are labeld. Bind plugs are included. I have less than 8 hours on this radio and it is in like new condition. So, why am I selling it? I'm moving to the Futaba 7c for the knob. The DX6i is a great radio, but for turret rotation with big gun, the Futaba makes more sense. Price? $175 plus shipping. I've got $250 in the radio and reveivers plus another $40 in the extentions and boxes---a fair price I think... My local club has first dibs as we are meeting for a build session this weekend, but I wanted to get this out there... Thanks for looking! P.S. I have the manual and stryofoam, but the box may have been recycled EDIT: It is an AR6200, not an AR6210. The 6210 is the DSMX, I have the DSM2 one.
