Ideally a nicely blended cuff would be available to reduce this element if drag. I started playing with shapes in CAD but had to stop as real work projects are pending. These could be made in batches by a 3D printing method (or by mould tools). An added benefit is that the triggers to fuse joint (left side especially) get its full complement of air, mud, water and exhaust fumes thrown at it. Covering it would help stop the typical corrosion problems but create another thing that needs maintaining. Fit would be via a clamp, with sufficient clearance (brushed) between main gear leg fairing and cuff to allow normal u/c movement (about 10 def each way). Weight in polycarbonate around 4oz each side.

Am pursuing a glitch and find that my nav antenna has a very low resistance unlike Com & Transistor antennae.

My thoughts were to blend the top and bottom over about a 4 inch radius both fore and aft of the leg, and I figured modifying the kit Could take almost as long as making it from scratch.
