Multistar 1704 V2 Prop Adapter Set 2 x CW / 2 x CCW.
High quality prop adapter set to fit the Multistar 1704 range of motors. Package contains 2 x clockwise and 2 x counter clockwise adapters and a complete set of the required fixing screws.
The shaft for the propeller is 5mm in diameter. These adapters fit also on DYS BE1806 motors. The supplied screws have phillips countersunk heads.
I changed my C'W-only Prop-Adapters on the DYS-BE1806 motors to this adapters because I wanted to use CW and CCW nuts. I could not use the Hex-screws from the DYS-Adapters because they are not countersunk and the multistar-adapters need countersunk screw-heads.
Material und build is good. Would have loved it when they would came in different colors for CW and CCW.These prop adapters are designed for multistar motors but they fit the DYS BE1806 2300KV motors just as well and basically any motor with a 2 mm shaft and apropriately spaced mounting wholes. It comes with 2 sets of screws, a shorter and a longer one, the latter of which fit the DYS motors perfectly. I got these cause they come with CW and CCW caps, the latter of which were not available for Dys motors back then. However, HK now sells the CCW adapters seperately for about $3 a pair, so I recommend you get those instead. Both work equally well.
motor shaft: 2 mm.
adapter shaft: 5 mm (gemfan 5030 fit without adapter).
I recommend to use loctite on the mounting screws. You can tighten the caps easily if you stick a screw driver shaft through the whole in the top.Bought some of these to replace a prop adapter on one of my DYS BE1806 2300KV, fits perfect and work well, definitely recommend to anyone chasing replacements or looking to have cw/ccw setup on their BE1806's.I bought them blindly and hoped that it worked. There was no further size info. It fits perfectly on the multistar elite 2204 and the emax 1806. I hope this helps anyone!
