Default Question about Props

Are there any companies out there that make props for electric powered planes that are more realistic in appearance than the plastic orange gws props?
Reason, Im asking is because I have a guillows Corsair that I am almost done converting to rc, and am trying really hard to keep it looking as real like as possible, and a Orange GWS Prop would just not do it.

As a quick fix you could just color the orange prop with a sharpie Maybe leave a little of the tips orange?

Ive thought about that, but would like to find out if I can get one already made that way first.

You could try the small props used for 1/2 or slightly larger. The MA props are realistic. Using the same size prop as you would with electric would mean a loss of thrust, but you could compensate by going to a slightly lower pitch.

Here's a link to the Master Airscrew "Electric Only" series:

They definitely look more like a full scale prop than the GWS offerings. Hopefully they'll have one the right size for your application.

it depends on how realistic you want to get. Masterairscrew makes wood props for electric but not very small ones . about as realistic as you can get. apc work very well.you want efficiency first and for slow flyers wide blade s are what you need.

The issue we deal with is generating good thrust in the RPM range of most park flyer electric motors. That's why they have big paddle-shaped blades. A scale profile Ham-Std. for your corsair would not develope any appreciable thrust.

There is an English company making adjustable pitch props that use a machined Aluminum hub 2, 3, or 4 blade with more scale-like blades, but you'll be dropping about $60 for the setup. I'll go home and look for the name and edit this message...

I like the master airscrew G/F props. They have white tips which look cool to me.

When the electics first started in the 70's they all used the same props. Though the large prop area helps it is not that much more effective. Take for example the Air Hogs compressed air model planes, they use a prop very similar to the 6-3 prop used for 1/2 A glow. They turn much slower RPM's than an electric yet they move the supplied model well. However that model could also be powered by a .010 glow engine.

Yup all the same props, which did not have the blade profile of a 13 foot Ham Std. either.

Which is why all electric and rubber band FF models use glow profile props... because they are not much less effective. [&:]

Sorry if I don't quite understand or agree.

OK FOUND THE ADJUSTABLE PROP!! Called a Vario-prop. Can be found here among other places.

I have never ordered from them, they just showed up on a google search. I lied about the price, too. Looks like about $30 plus shipping gets you going.

when dealing with SLOW flyers & LOW RPM it makes CONSIDERABLE difference .you are mixing apples /oranges. what electric /rubber flyers do you hang around?i certainly do not use gas props on my electrics unless nothing else is availible.why do think the light weight very slow flying indoor rubber microflim flyers use very wide blades ?
