Round 2: The LAMA V4 Dual Swashplate Project : Push Pull Straight Link Bell Head
Revisited the Dual Swash Mod and this time with the symmetrical Bell Head Push Pull mechanism and using straight swash to mixer linkages;
This is a continuation of the original concept found here;
This time the linkages are symmetrical and straight despite the 90 degree shift. The link configuration follows a PUSH-PULL mechanism minimizing any slop in transmitting the swash pitch data to the upper rotor blades;
The idea is to relocate the mixing arm close to the corner of the grip allowing a straight swash to mixer ball link. The sync arm is then removed (from the original config) and relocated just above the swash using two servo link arms tucked inside the upper shaft sync forks.

* Take note of the bind free flybar and how the mixers move with the swash. Such configuration allowed me to maximize the transmission of pitch data from the upper swash to the upper rotor blades.
