Product Description
Please read my article in aeromodeller No 929, September/October 2014.
Me thinks white processed versatile plastic is most suited for the job. However I used the cheaper standard stuff.
I can make other colours available on request but i don't see a huge demand for it.
For pricing reason I "glued" two parts together as one; it is cheaper.
The valve itself is a plastic disc 8mm in diameter made from some disposable food package.
This should work on the ED Hunter too.
