If  my Valach Ignition has a second JR cable:

It offers you a kills switch functionality. Is for ON / OFF switching your ignition.

Hook that up to your receiver, set up a negative/positive mix and you are set to go.

 

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.

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.

https://www.aeroscale.shop/collections/valach-exhaust-solutions

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.
