Valach motors were designed with Fiala props in mind. Should you want to run the  shown pitch and diameter recommendations you WILL need to run a Fiala prop. Should you want to run props of a different brand you will most likely have to drop 2 in pitch due to Fiala's unique airfoil choice. Other brands plain run at a higher drag rate.

 

Very convenient to have as the Valach does not come with preinstalled throttle and choke horn:
