Hope the pic is good enough..GMP cobra mechanics with (I believe) Schulter blade grips. The driver is single ball link but it spins freely around the mast so the phasing will be incorrect. There is a slot in the mast which I'm guessing maybe for a set screw to lock the driver but the driver has no threaded hole to get a set screw through it. One side of the driver does have a small bolt and nut that can be tightened to "clamp" itself on the mast but I would still think a set screw would be needed...or am I wrong?? Any ideas or input?? Thanks.

looks like Hirobo / GMP ... but only am guessing by looking at the swash follower and the collective arm to the left side .. I have never seen quite this setup up before ... GMP had some thing close to this on their competitor many yrs ago ,, would have to look at mine at home to be sure .

Clamp only and a set screw is not used as this allows for the phasing to be adjusted in order to take care of any slop in the head.

Thanks for the help thus far. This heli is my winter project and I'm really excited to get it flying next spring. I bought it used at a hobby shop..it was simply collecting dust. This thing needs to be flown! I'm not too familiar with flybarless heads so I'll most likely be adding a futaba 750 3-axis gyro to assist me. It's sanded and paint from klass kote is on it's way. Thanks again.

The swashplate looks like GMP or Hirobo. My Cobra had the phasing adjusted by a rod with ball links on each end. One end attached to one of balls on the side of the swashplate. The other end to a ball on a vertical radius arm bolted to the side of the main frame.
