Also the chassis will be white and here are the part #'s to update a XMW to a 211xm and a general price range too
New Chassis Part#10334079 (100$)
New Waterfall Part#13450694 (18$)
New Rear Battery Brace Part#13404054(8$)
New Battery Strap Part#13404055(12$)
New Rear Brass XA mount Part#13450695(15$)
So for about 150$ you can upgrade a TRF201XMW to a TRF211XM... sounds a lot cheaper to do it that way vice buying a whole new kit
