Recommended prop: Please see that you run Valach engines on Fiala props.
Fiala owns and makes Valach engines, the development of the engines goes hand in hand with the development of their propellers, these is truly the only make that has a custom prop in mind.
Props are not simply paddles that drive an engine forward, they are sophisticated designs with well thought-out airfoils.
In this case engine are propeller are matched.
