Rudder Hinge Bolts instead of screws?

Post by Blueflyer »

Can anyone show me in the plans where it shows the hardware (screw or bolt and nuts) callout for the hardware that attaches the rudder/elevator hinges to the airframe? I dont see why not to use AN3 bolts to attached the hinges to the airframe? Any comments or thoughts?

I generally see nutplates attached to the backside of the wood that the hinges are attached to, with machine screws going into the nutplates. There isn't anything saying you can't use bolts with nylocks to attach the hinges, but they will weigh more than the nutplate/machine screw combinations and you'll never be able to get at them to remove the hinges without cutting into the fabric. Builder's choice.

Thank Oscar, very helpful! How does everyone attach a nutplate to the wood structure?

Nutplates attach to wood with either one or two small screws, depending on the style of nutplate. Might as well use the ones that take two screws and you'll never have to do it again.

I used #8 MS screws and nuts.
Seems to be working out so far.

Just for additional information, here's how the GN1 has the hinges (eyebolts).
