Master Airscrew propellers

I have seen many posts on this forum on various brands of propellers.
The only ones available here in Oslo, Norway are Master Airscrew.
I have got a 9x4 and a 9x5 to try out on the OS .25 LA.
Anyone have experience with these props?

There heavy and are grossly unbalanced!! and dont forget to lightly sand the edges so you dont modify your finger tips. but they do make wonderful epoxy stirring sticks!! But what do I Know Paul-

They may not be everyone's favorite but they are cheap and do work. I've found that almost any brand of prop that I buy requires balancing. I typically use the Master Airscrew props on my sport planes and on my sons planes (he does crash occasionally ). My Brodak Flite Streak is currently powered by an OS .25FP turning a Master Airscrew 9x4. The OS .35FP on my SIG Twister uses a Master Airscrew 10x6. These MA props work fine for these sport planes. On the planes I fly in competition I use Zinger or BY&O props.

I agree with Dennis V on this. I find the Master Airscrew props to be great sport props assuming you remove all sharp edges and balance properly. For serious work, I like the APC's as apparently a lot of other modelers do as well. I use to like to cut down the stock Master Airscrews and see what the effect on engine/plane performance would be. I recommend you do the same as it is a great way to learn about prop performance and the costs of the Master Airscrews encourages this sort of dinckering around.

What type Master Airscrew prop are we talking about ---- " black plastic" or wood? I have used both, but am curious about how good the wooden ones are. The quality of the wood ones appears about as good as other mass produced wooden props. What are your thoughts?

Don't forget that they make several lines of props now. They've got a line of "Scimitar" props (grey in color) that becames so popular with the Fast Combat crowd that they produced a special "Combat" version of it, with a solid hub.

They've got wood props, electric props, folding electric props, Slow Flier props, etc., too.

Their wood props (at least in the 10X6 size) look really good. Balance is very good and thrust at rpm seems very good. Best of all, if you can find them, the price is right.

Hmmm, that would make a great TV show.

I switch off between a Zinger 8/4 and a MAS 8/4 on my overweight Akromaster. The Zinger's do seem a bit smoother running. I sand all my props during balancing, so don't know about any sharp edges.
My familys from Oslo. Do you know any Aablu's?

These are the black Plasic ones (with white company logo)

Those were the ones i was talking about. And like dennis said, after balancing and sanding, they make an ok beginers prop because they are pretty strong. I carry one in my flight box as emergency back up. I just dont like black props because there so hard to see when the motor is running. But if thats all you can get, then by all means use it and enjoy!! Paul

Norvaldo, lemme give youa piece of advice:

Paint the tips yellow or white!

This will save you a lot of pain.

Don't ask me how I know...

Ok Will do
