Pretty standard stuff for us who know the MX series. Other than a larger frame width, basically the only thing different on the 500 is an adjustable battery tray (angular).
Nicely built with the standard superglue of all the hardware from the factory
again typical for the ARK/MX series.
The thrust bearings were oiled, but I applied grease to them upon reassembly.
Got some inquires gone out looking for info on the gear mesh, I still think it is 1.0M. Waiting for replies.
Once I get all the electronics in it I still think it will be lighter than my HDX-500SE.
Of course the bearing blocks, tail case, tail slider and TR grips along with main blade grips are also available in the Blue CNC.
