Its just a high wing trainer plane in disguise. But the airfoil will cause it to balloon around.
It would be better as a semi-symmetrical airfoil tracking through the wind with less fuss. As a RC trainer
in a small field you should be able to see it easy enough I would suggest fabricating a throttle sleeve unless
you already have one on the engine. The Pee Wee came with a nice RC version throttle sleeve. I use them
with great success with the TD .020.

Here are some mods
More rudder
Landing gear / tail wheel better suited for grassy park flying
Engine size upgraded in proportion to plane for a .020
Airfoil thinner and semi symmetrical
Pic is close to scale if you have a 23in monitor
Canopy is leaner for less drag.'
Could do with ailerons

You may have seen my Roaring 20 flight vid here:



I built it without a canopy and have flown it plenty of times with my 010 until the fuse got soaked in castor and now I run it with 020. I am planning to rebuild the fuse so that I can fly it with either one.

Here is the original setup: https://www.coxengineforum.com/gallery/Personal-album-of-balogh/2011-11-19-1936341-pic_328.htm

I must confess this is a superb little plane that flies with either 010 or 020 very well. It glides long distances when the engine is off and a very forgiving beginner R/C plane. Highly recommended.

Thanks Brad and Andres , can see where it could stand some upgrades , are you using nano servos in the plane you built ? 2or 3 for rudder elevator and maybe throttle , don't think I will worry with aerlons at this time , if built I would like to get it done before the end of summer lol. have you got a pic of the servo set up Andres ? Looks like a good easy flyer. Thanks again . Eric

Eric,

mine is a simplistic version with only 2 channels, rudder and elevator. This can easily be upgraded to 3 channels for a throttle etc. because there is enough space in the fuse:



I have a 330mAh battery in the nose, a party baloon tank behind it, a micro-switch harness with a charge cable included, a Futaba 5 channels receiver and 2 Hitech nanoservos in the belly. The fuse is richly soaked in castor despite my efforts to seal it when built...more than a 100 hours in the air with the 010 splashing the castor around has made its mark on it...so sorry but this plane is far less elegant than you guys usually present here...age makes you torn and frayed but all the same, beautiful.... lol!

I would take Eloquent over Elegant any day. And that plane is surely Eloquent.
