Fits the MBX6 perfectly, well super snug, but MAJOR issue is that you have to watch these packs as they swell. Only charge at 1.0amp and not the standard 2.3amps. These are touchy about being overcharged, discharged, and heat. I think ProTek 'Amain' needs to redesign these or have the company who makes these put better LIPO cells in these RX packs. I like all other ProTek items but these are way down on the list of the normal quality you would expect from ProTek, so I would suggest to look elsewhere for the LIPO RX flat packs.
