Hi Steve,
I am waiting for my finish kit so in the mean time I'm also fooling with the throttle quad. I am going with only throttle and maniford pressure on the quadrant (2 levers) for two reasons. One, I like the vernier style push pull knob for mixture because of the fine adjustment it allows. Two, I'm going with manual trim. I've designed a plan to stack the trim lever behind the quadrant. It's going to be part of the quadrant. I'll post a photo when I finish it this week.
Here is my point...to more accurately facilitate placement I ordered, and just recieved the stock control cables from Van's. If you are planning to anchor the cable on F-402 you might not be able to place the quadrant that far back without some type of extension. In any case, your placement will probably be at the aft most reach of the treads on the rod end (clevis) and the threaded casing. Just thought I'd point that out in case this matters to you. I'm sure someone out there makes a threaded extension. The cables are nearly identical to the control cables in my 18 foot runabout boat. I have also seen builders fabricate a "U" shaped bracket to bring the cable anchor point aft. I hope this helps.
Nice metal bending work.
