Less play in the 4G6 rotor head – Gaui EP100/Minizoom Pro V2 mixer arms
The stock Walkera 4G6 mixer arms have way too much play, also no ball bearing. So i took some aluminum mixer arms from the Gaui EP100 V2 aka Minizoom Pro V2, part 203580 (silver) or part 203640 (black). The original ball links can be removed and the Walkera ball links fit into the threads in the Gaui parts. The Gaui parts work with the plastic Walkera bladegrips, if you use the metal bladegrips some spacers are necessary. The Gaui arms are a bit shorter but that doesnt seem to change the feel.
Result: The heli feels much more precise and most unexpected pitch-jumps are gone. Still have to shorten the plasic on the bladeholders where the screw goes in.
Thanks to Don on RCGroups – i first saw the mod from him.
Here is a video from RCGroups user jaguar_5, showing the difference:
