Probably not too much types are available there, in good measures...
It was far simple to put on some 12-6 APC; I have had it for long time, but I needed to find something better, some 3-bladed type.
There is 11-5.5E from Mr. Mejzlik (Czech Republic), this is excellent, but too small for me.
As I would like to fly slower, (5.3 ÷ 5.4 secs/lap), I needed larger.
So I made one12.3-5.5 prop of CFK, and it is great pleasure to fly with.
It weighs .88 oz.
