Once you start your engine you should see the FINE led flashing green.
This indicates controller is attempting to drive in the fine direction, but the propeller is already at the fine pitch stop.
You may see this indication many times when the throttle is only partially open. It shows the control system is working properly but that the current selection of speed and throttle do not allow for governing to the set speed.
When you are flying, you may see an occasional flick of orange on either the FINE or COARSE leds. This is the normal operation of the propeller making very fine adjustments to the propeller pitch to keep the engine speed constant.
If there is a large change in throttle setting or aircraft attitude (or you have selected a different engine rpm), one or other of the indicators may stay on for longer.
If you are in very calm air, with no change in throttle, you may see no indications. This is normal.
During automatic operation, this indicates the controller is attempting to drive in the coarse direction, but the propeller is already at the coarse pitch stop.
This is most likely to occur if you are flying at a higher than normal altitude, at high power settings. It would be a clue that the coarse pitch stop is currently set too fine.
The coarse pitch stop is set at the factory to a nominal value, but it is expected that you will have to adjust this to your particular conditions. Please refer to the Operators Manual.
A solid red indicator in any of the circuits of FINE, COARSE or FEATHER is an indication that the propeller is drawing too much current.
If this occurs in AUTO operation, constant speed regulation will be suspended. The indicator can be cleared by switching to MAN.
If you need make a pitch adjustment for safety reasons, you can attempt to do so in manual, but it is advised that you investigate the problem properly before further automatic operation is attempted.
How to order an Airmaster Propeller
Provide your details for us to fill out an order request. Typically we will want to know your contact details, delivery details, aircraft and engine details and the type of propeller you have chosen. We have a form that can help in the collection of this information.
Airmaster will take the information you have provided and make up an official order for you. This will lay out clearly all the details of what has been ordered, how much it will cost and where it will be delivered to. You will also be given an estimated shipping date.
Airmaster Product Codes
Airmaster propellers are described by a combination of letters and numbers which describe the configuration of that system or part.
I want to thank Airmaster for the support and not least the amazing products they produce.
I was in contact with propeller manufactures all over the world before I went back to where I started my search. No one could for sure tell me if they could deliver a propeller that would meet or exceed my demands within speed and power output. The custom Rotax 912 Turbo, Intercooler and fuel injected engine delivers 135HP max and the AP430 – SNR64EN propeller has no trouble
dealing with that amount of power.
The first thing I noticed when receiving the propeller was how well everything was wrapped and packed. The first impression was stunning. The propeller assembly was straight forward, and mounted in only a couple of hours as I had cut holes for Governor controller and the manual pitch switch. The whole assembly lights up quality and well engineered construction.
When starting the engine with the propeller for the first time, the first thing that truly amazed me was that there was no sign of propeller blade tracking. They run straight like a knife edge.
The low noise the propeller produces is also a thing I quickly noticed.
First take-off took me by surprise. I did for sure expect great acceleration and climb with that amount of power and a pitch propeller, but nothing close to what I was about to witness.
Take-off was within 80 meters, steady climb at 2300f/m @ 85KTS. With a flick of a switch the RPM stabilized at 5000rpm and the plane just speed ed up to 145KTS IAS. Wot runs gives me 160-165KTS IAS 2500AMSL.
Thanks you so much !

After the installation of the Airmaster prop we were able to get the benefit from the extra horsepower from the turbo 914. We could see between 5 and 8 knots better
cruise at 5000 rpms. The most benefit that we get from the prop is when we go to high altitude then it makes the benefit of the turbo charger work correctly.
The constant speed controller works excellent and the numbers that Airmaster dialed in for the turbo engine takes any guesswork out of setting the prop.
I could not be more satisfied with the prop, the controller and the support that we got from Airmaster when we ordered the prop. Also the installation was very straight forward and easy to complete.

My L-42 is fitted out with propellers produced by NZ "AIRMASTER" . As far as I know, when this aeroplane was in the process of creation, russian constructors tested different types of propellers and approved only "AIRMASTER" 's. I'd like to say that propellers hold the water ingestion very good without any fractures. The fact of importance is controllable propeller. My friend Kirill Vilchinsky has L-42 too and we both thank engineers of "AIRMASTER"
