@Mustang51. Feel free to upload and list it. I based it off a plane I saw in a Canadian Documentary of the same name on YouTube a while back. The original never got off the ground either
And thanks for the tips

Although this is an old plane, it’s still a pretty cool one and with a few simple fixes, it could fly very very well. Firstly, the elevator has to be further back in order to push the CoL further to the rear. To do this, extend the booms to a point you think is sufficient. Secondly, make the prop size bigger. Unless you purposely put power restrictions on it because you want it to act a certain way while it flies, changing this will make it manoeuvre far better. Thirdly, remove most of the fuel. The engine on this plane hardly uses any fuel so there is no point in all the extra weight making it slower and less manoeuvrable. Lastly, add some dead weight to the nose in order to put some distance between the CoM and CoL. This helps the most in keeping the plane stable and able to make tight turns. Something optional is just removing the elevators in the main wing. I’ve done all this to it if you would like me to uploaded unlisted and tag you.
