The technique described above, is commonly called the "parachute" by 3D model flyers.
When I got into small electric models ,especially the things I could build from flat sheets of foam, Iwas able to proove/disproove a number of of rules about flying
The most interesting were concerning very low speed flight .
The Lightplane rule was to simply avoid low speeds - they can kill you.
Seen that happen too often.
Learning how to control a deep sink takes a fair bit of practice
In the little foam models -if you screw up -maybe some bent foam and a broken prop.
In Light planes "stretching th eglide" or dragging th plane in on landing are risky -ditto for typical models of the lightplanes .they simply are not good at "departure " flight. One hard rule is to leave the ailerons alone and concentrate on rudder corrections. It's counter to the feeling that you must "pick up the low wing".
