    Default Jeffs 340 Kitfox

    I found an easy place to mount the AP servos - behind the seats. Can't use the header tank due to the fuel system I am using. Might turn it into a smoke tank...
    Made some fancy tube clamps to attach the pitch and roll linkage.
    Need to get my fuel valve from Andair. I need a duplex fuel valve. The area under the console is chock full of fuel pumps and filters.

    I also mounted my servos behind the seat. Looks a little flimsy, but is quite strong.

    Hello
    I hope to put AP in my SS7 but I'm a bit concerned about how difficult it is. Almost seems like you need engineering knowledge. I mean, it seems that everything that you do, from the lengths of the drive arm to the lengths of the push pull arms, changes everything with regard to rate and distance of travel. Are these systems difficult to figure out. I know the directions are not aircraft specific unless it seems your building an RV.
    Thanks, Eddie

    The documents for the GRT servos are pretty easy to understand and they emphasize not to over center the servo arm or you could break things. When I set mine up, I aligned the servo arm pivots with the idler arm pivots for both roll and pitch. The tube clamps were installed on the idler arm to match the outermost hole on the servo arm. If this is too sensitive I can always move the rod end on the servo in.
    It's really not that difficult, just stare at it a while and you will come up with a plan... thats kinda how it worked for me

    I'm finding out that Kitfox must have a back room with all kinds of stuff that they don't put in the catalog.
