I'm not sure what type of pull you want the engine to have on a Decathelon.
Here are some recent #'s.
Last weekend the DLE30 was spinning a Xoar 20x6 7350. Tons of power and verticle pull, although it wasn't a fast prop.
Yesterday I tried the Mej 19x8 Carbon prop. For my SBach, I think I like this prop better than the Xoar 19x8 and Xoar 20x6. In all fairness I haven't tried a Xoar 19x8 since the first couple of flights. So I would have to put one back on and try it again since the motor is starting to run stronger now. I sold the prop to a guy who needed one in a hurry. So I have to get another sometime to try again.
The Mej was spinning at 7490, consistently. I couldn't get it to break 7500. Maybe the next 1/2 gallon will get it there. It only has half a gallon through it now.

Now yesterday with the Mej 19x8, The plane was pulling stronger in my opinion.
The plane flew faster at lower throttle setting, and had more get up and go when I opened it up. It made the 20x6 feel like I was driving around in first gear all the time.
A few things that made me like the Mej better were:
It was more quite than the 2 Xoars I had run previously.
I put the plane in a hover and then punched it. It started climbing and accelerating sweet.... My SBach is 12 and half pounds and the 30 is pulling it like that on half a gallon ???? Can't wait to go through the second half.
Unfortunately at 6ozs of fuel per 12 minutes running and flying.....Its going to take weeks
Lastly, this is an important one......

Its sexy as as h#*! with the red and black colour scheme with carbon landing gear.

I'm not sure what weight the Decathelon will come in at. But if you don't fill it with rocks, The DLE30 should pull it very well. Won't be a hover machine, but it should fly it really well.

Exact measurements are 6 5/8 inches with the tail down. 4 1/8 inches with the tail up and the plane level.

Oh I almost forgot to mention I'm using 4.5 inch dubro inflatable tires with a small amount of negative pressure in them. So they're probably about like 4.25 inch wheels as they sag a bit.

Can you post some pics of your scheme ansd setup?

Jim, if you are interested in an rcgf 32cc gasser (rear intake reed valve, side exhaust) I have one I just finished reviewing you could have cheap. Flew several flights on a 15 pound giant scale stinger arf (all I had for flight testing) even though it was too large a plane it flew very respectably with a 20x6 apc.

Pm or email for details.

Scaleguy..

This picture is with the Xoar 20X6


Here is a picture showing the clearance with the tail down.


This next picture is with the tail up and plane level.


I included a picture farther away to give you an over all feel as to how it looks.


I included a couple pictures of my landing gear fix as I'm sure I will get questions about it. They are eye bolts along with heavy duty throttle return springs. I think the springs are used for GM trucks with electronic throttle position sensors. The spring simply gives the throttle pedal a comfortable feel as we are used to with the old throttle cable setup.
