    Robin Ultralight

    Hello new board!! my name is mark Calder, I'm the designer of the old Wren ultralight, I have a new Ultralight named the Robin that I am getting ready to cover. I put this Blog together that goes back a few yers, it covers all of the design and build of the Robin.

    Please take a look and give me some feedback if you will. Eventually i will be selling plans. My near term goal however is to have the robin to next years Lakeland Airshow

    Mark, I've been following your blog for a year or so. Great work - great explanations of your progress - can't wait to see the Robin in the air. Keep up the good work!

    I just completed a light weight fairing for the Vert Fin/Rudder. its a pretty interesting process if you have never worked with foam, glass and Gel coat. The final completed fairing weighs 3/4 of an ounce.

    This is a foam technique I use to make compound contour parts. There are quite a few references to this in my blog and I think the average homebuilder will find this quite useful.

    I finished the fairings, the canopy, fairings, tip caps and instrument panel are all in for final paint. I installed and calibrated Jim Weibes Belite fuel gauge. I have one final job before I start to cover the Robin, I neeed to rearrange my shop so I can reattach the wings and rig the aileron cables. Thats the final job!!! I'm starting to see the light at the end of the tunnel.
