I noticed that after RCU crash last night my previous post with my tailwheel pics disappeared. So here they are again!

The tailwheel bracket is a piece of 1/16 balsa with a 3/8 inch long piece of 1/16 alum tubing CA glued to end - cross grain. Then I wrap 2 oz carbon cloth from one side of the balsa across the tube to the other side, when cured, trim and epoxy 1/4 triangle stock on both sides of the carbon/balsa lam to form the mounting surface - when that cures trim and sand to fit the mounting area in front of the rudder post. I don't remember what size music wire - but it's the size the fits the 1/16 tubing, bend to shape - I made the wheel retainer by cutting out a tiny circle of plastic - slipping that over the music wire and adding a drop of epoxy. I think the tail wheel is 3/8 or 1/4 - you can see all this in the photos...

I may remake the length of the wire, but at this size it will keep the bottom of the rudder of the ground
and has plenty of support.
