You are correct, the fail safe should have both the rudder and aileron to the same direction. This would cause the airplane to drop out of the sky without covering much distance. Much safer as long as you fly over an empty space.
I've never heard of such a fail safe.
The best and most common fail safe to use is low throttle (upto 15 %).
Slight up elev and slight right rudder .... so that the plane keeps on going around in circles and does not fall with a spin, As most of the time the planes are in level flight position.
Secondly ....... I think its Very Idiotic , this is a total waste of time and equipment. Why would anyone build such a thing ? Its not impossible to make but its very stupid to attempt for it.
I have seen lots of planes and concept aircrafts but I hardly remember one with such dimensions. Has any serious flyer or aviator gone for such a thing ? I have read the profiles of these champs here (team RCU)..... all of them went for good aircrafts instead of wasting their time. People should try to benefit aviation from their research , not waste their time.

Now that AIAA has been mentioned, there is a legitimate purpose. AIAA and SAE sponsor university level competitions for designing, buildling and flying airplanes to meet the criteria for the contest.
The events are quite popular in the technical universities, with competitors from all over the world coming to the US for the finals, and some nations spinning off their own series, as in Brazil.
It's as close as a student can get to the real world they'll be graduating into, with the experience of designing, building, explaining the design, and proving it by flying it, instead of the usual academic method of talking the subject to death.

The AIAA Fail-safe rule: o Radio fail-safe check. All aircraft radios must have a fail-safe mode that is automatically selected during loss of transmit signal. The fail-safe will be demonstrated on the ground by switching off the transmit radio. During fail safe the aircraft receiver must select:
Throttle closed
Full up elevator
Full right rudder
Full right (or left) aileron
Full Flaps down (if so equipped)
The radio Fail Safe provisions will be strictly enforced.
