NOTE: This aircraft presents a noticeable pitch-down tendency. Messing with the airfoils solves that problem but results in unacceptable flight characteristics, sometimes sending the aircraft out of control in turns. It was meant mostly as an experiment and as a meme, so it's likely staying like this.

"SOMEONE STOP THESE MADMEN" - Engineer from Socrux's Defense Department, again, upon once more seeing the Experimental Research Department folk wasting money

Ah, the Cold War. Research on all sorts of crazy ideas given funding just to see what would happen. Among them, the annular wing is perhaps one of the most unique. After much wind tunnel testing, Socrux Experimental Research engineers decided to construct a full-scale testbed for the concept.

With its tall landing gear and strange looks, the aptly named "Barril" (Barrel) Conceptual Prototype S.C.P-157 was hated by its test pilots. It was difficult to control, and the rudder acted more like an extra aleiron. Some test pilots learned to use this to boost their roll rate, and when elevators were applied alongside this technique, it was easy to depart the aircraft from stable flight. As a safety measure, no less than three drag chutes were installed, to be also used as an emergency spin recovery system.

Overall, the aircraft proved to be unexpectedly agile, with an impressive roll rate and good maneuverability on pitch, but its speed was disappointing and overall it was felt that such a radical concept was not worth pursuing at all, given performance was comparable or inferior to conventional aircraft at the time, with small advantages that didn't really matter much. As such, the Experimental Research Department once again wasted considerable sums of money and effort for essentially nothing, and as a result, after the failure of this project they recieved a major slash in budget and were assigned a board of supervisors from the company's other departments to oversee their actions.

    Well then ill just provide them with an underground base and funding of my own, why? You ask. Because i enjoy causing chaos

    @atgxtg Oh, I did mess around with that too. I used all sorts of angles on the canards, and with one of them I got really good trim, but I found it didn't turn as sharply anymore. Decided to keep it as is. If you want straight flying though, setting the canards to 0.5 to 0.7 degrees, or making it a semi-symmetrical airfoil does the trick nicely indeed.

    It's messing with the airfoils a bit, but if you add a -0.60 degree tilt (X-axis) to the canards it will eliminate most of the pitch down tenancy.Also turning on the Trim for the canards helps.

    I made a successor with those changes that you can look at and fine tune to get the performance you want.
