Who makes electric inflight adjustable props for small Lycoming’s

My Airmaster is rated at 60 Hp per blade in an AP430 hub, how many Hp is your small Lycoming?

115 hp at 2800 but in real life 100 hp at 2600rpm

An AP332 hub takes 60mm blades, like Bolly, and are rated upto 40Hp per blade, from memory. I was keen on Sensenich blades but ended up with Whirlwind Razor blades, both of which have a 70mm boss, hence the upgrade, but also came with a small weight penalty.

Airmaster Propellers

 

Home page shows a O-235 Lancair with airmaster prop...

 

If you already have one of their "supported" blades, you can send them to airmaster to be modified and fitted to your IFA unit. (Saves buying new blades)

Hub for a 2 blade O-235 AH-523

Be aware that a 70 inch prop installed in an Airmaster hub will have a larger diameter than it had in, say, your existing Bolly hub.

These guys are producing props for Jabs and Rotax and in development is the model for Lycomings.

 

Direct drive 4 cylinder engines have only 2 power pulses per rev. Rotax have 4. Higher loads in the Lyco case.

Has any one fitted one to a 230 . What were the results

 

 

[BirdDog]

My Sporty has a Woodcomp in flight adjustable.

 

 

[Paul davenport]

And how much improvement on a fixed pitch was it

 

 

[BirdDog]

I have no idea on that question! Mine came factory fitted. I cruise nicely in calm air at about 5300rpm, WOT at about 115kts

 

 

[Paul davenport]

And what is a sporty ? What does it look like? I would like to know what difference it would make to my j230. Spending up to $13000 to find out it’s ,not as good as the sales puff would hurt

Very nice. Mates father had one and loved the full fine decent rate

 

 

[BirdDog]

Thanks and Yeah - she is certainly a nice machine to fly.

You can park it in my hanger any time you like. Flew on in Shepparton once with Peter Harlow from memory it was well balanced

 

 

[BirdDog]

They fly amazingly well. Very stable and very predictable. Comfy enough, although I would love some higher backed seats. But that would restrict access to the storage behind the pilots.
