KR-2S Custom Dual Control Stick Tutorial

Problem: I just can't seem to keep it simple... I wanted to keep my center wing stub area's completely free of cables and controls so that I would have larger fuel tanks and keep the tanks simple boxes of fuel with no complex joints to accommodate cables and controls. Flaps will be accommodated via a torque tube behind the rear spar.

Solution: Move the control sticks to the front of the spars. This could be a first. This requires a completely custom built control assembly with dual S shaped sticks. Sounds like fun... Here we go.

I have decided to take lots of pictures on this control assembly building to show exactly how I build it. Hopefully someone will find this information useful. This is by no means the definitive answer to how one should build forward or standard control sticks... I found several ways it could have been done. This is just my way. Feel free to borrow and improve on my idea's. Diagrams will be added here when I'm done in a few weeks.

More pictures to follow in a few weeks... Going on a short vacation to Kelowna B.C. Canada
