BTW - the Y4 design has been pretty much abandoned. The extra weight upsets the CG too much, also, it really did not give enough yaw authority without some weird height change characteristics.

The yaw servo vibration issue was pretty much fixed with the new linkages to reduce the play on only the servo gears and tweaking the FC (probably the main problem in the first place)..... However my prototype crashed with a blade failure before I could do any endurance testing on it......
