No I am not making any more, I made 6, but too much work in them . Danny at Danson trikes is making one from fiberglass and its going to be made for a radio I think. I sent him my desing and he copied it.  Lates idea I had was to take heat from motor and blow it up the back of the box for a heater, so thats my next project., did that on my ultralight planes and worked good.   Wayne
