Having lost (literally, see the glider topic) my scale Glasflugel Libelle I wanted something scale to replace it.
The twin Wren was fun to build and fly so a bigger twin.
The Cessna O-2 was the military version of the Skymaster and used 2 blade props. That 'night' camouflage looks pretty cool.
The push/pull arrangement meant one engine could be shut down with no asymmetric forces.
I recently bought a DX6i which has the ability to do 'mixes' so how about arranging a motor shut down in flight?
I found this 3 view which gives some of the fuselage cross sections.
Scaling for 9" props gave a useful span of 53".
As in the full size it will use counter rotating props so with both running there is no torque reaction either.
The 1200kV 2822s I used in the video each give about 20oz thrust at 15A on a 3s. I guestimate as a lightweight belly lander an all up of 20oz so it should have a more than adequate performance on one and on two? Straight up!
