On my Liki Tiki I'd like to install a hidden tail wheel inside the rudder. I'm thinking of haveing a thin wheel well in the rudder made of light ply. I'll water proof it and have one side removable, held in place with three sheet metal screws. The wheel will have a short axle that will be epoxyed in place so wheel and axle will move together. The ends of the axles will fit into holes in the lite ply sides. Dose anyone here have any experience with this or can let me no of any unforeseen problems?
