This is the basic design for my Seafury landing gear. An alignment pin may be added in a vertical slot to retain the strut alignment and the legs will be covered with Streamline Strut fairings from http://www.streamline.8k.com/FAIRINGS.htm

This is Lynn Hyder's scratch built KR2. My gear will look very similar. The forward WAF will be replaced with a 7x9" landing gear mounting plate made from .125 chromium-molybdenum general purpose alloy steel plate. The upper part of the gear will be welded to this plate.

Here is a Zenair 601. That is the look I am after but with a more rounded tail and invasion stripes
