Hi
Being new to this sport after years of absence I wonder if any one can advise me
I have recently purchase a Hanger 9 F4U .60 Corsair [HAN2725]
For this I have a new DLE-20 gasser and would like to fit a 3 blade prop
Can anyone recommend a carbon fibre or composite material unit suitable
As this has not been run in I will need 2 sizes

Your advice is greatly appreciated

The available selection of three blade props is pretty limited. If you are willing to use a two blade it will be a lot easier to find a match for the engine/airplane and your flying style.

A commonly used two blade for this engine is a 16x8
A 14x9 three blade (Master Airscrew makes one) would be slightly less load on the engine than the 16x8 two blade
A 15x7 three blade (Master Airscrew makes one) would be slightly more load on the engine than the 16x8 two blade

Gutaaaooo

Hey got any pictures of the engine in the plane?

In the gas engine forum I think there is a page on the DLE 30 with the different props people have used and RPM readings. You may want to go there ans see if they posted one for the 20. Three blades are hard to find in hobby shops these days and spinners are even harder to locate unless you order them for places like Truturn.

Hi Guys

I would like to thank you for the information on prop choices
I have purchased a Master Airscrew 15x8 to run this in then I intend to increase this to a 16x8
You are right 3 blade units are rare
so once again your input is appreciated
Good weather and fine plane is music to my ears
As soon as old faithful is up and runnning i wiil post photos

Engel make some small 3-blade carbon propellers.

Including:
13.5x13.5 3-blade
15x11 3-blade
15.5x13 3-blade

I think 3-blade propellers are more suitable for larger models, as a way of reducing noise. A 3-blade propeller normally has a smaller diameter than a 2-blade propeller of similar load, therefore the propeller tip speed will be lower and hence less noise. This should not be necessary on a 20cc motor. With that motor you would probably want to use the most efficient propeller available, and that would be a good 2-blad prop.

What sort of performance with the 3 bladers did you get? What spinner did you go with?

In the giant scale forum there is a sub forum for gas engines, just click on the blue line to get to the sub forum. More info then you want to read on the DLEs now.

The master airscrew 15x7 3-blade works GREAT on the DLE20
