 Due to customer request allow me to share with you some essentials that I personally recommend purchasing with your Valach engine.

Valach, just like 3W, Desert Aircraft and many other leading manufacturers of engines, do not supply an exhaust solution. Hence I recommend that you order one with your motor, to be found under Valach Exhaust Solutions on this site.

4-stroke gas engines do run on pre-mix oil lubrication. Said oil will be expelled through a drain on the back plate of the motor. Should you want to avoid a dirty airframe I recommend getting our oil catch system, to be found under accessories.

Furthermore I recommend getting the feeler gauge blade set, an ignition battery from us (we have two technologies available) and our external APS fuel pump for those who want the added safety of redundancy.

 

And last, a very important pointer: 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.
