if you have any length of building experience, I have converted many kits to tale draggers and the cost has been $15 or less, unless you get fancy with your hardware.da Rock hit it right on the head with advertising.its like things on the menus at most fast food places you hardly get what’s on the picture but its there to make your mouth water. kits with the extra instructions for modifications they will have an additional parts needed line in most cases and that’s how they get by with advertising pictures of what they can look like.
