Got quite busy at work lately. I got the micro coaxial platform only last weekend and had the chance to modify it only last night.

parts detail of the coaxial micro mod;

Upper Swashplate - Old MSR swashplate with the arms removed and replaced with metall linkages balls from an old walkera 4#3 metal swashplate.

Linkages - Spare linkages from a ne solo pro. lower swash and upper swash connection used were from spare servo arm linkages (msr and solo pro).

Upper flybar hub - Walkera 4#3 flybar hub with ball linkages mounted on the side coming from the ne solo pro mixer arms.

and a CA tube. <---- very reliable tool for micro helis

If only I had more money. I am actually quite glad you have paved the way on the twin swash. I was actually up quite late last night (4am) designing a dual swash setup where the Lower blade sat under the body until barrack popped my bubble and told me it had already been done. LOL
Now, I can pretty much settle in and copy most of your prototype since you have already put in the brain hours!
