I still say rebuild the wing and install inboard flaps. I have around 100 hours of flight time in Cessna 150,152,172,and they all use flaps. A 152 Cessna with full down flaps can fly as slow as 40 mph. Without flaps 60 mph. With full down flaps you can safely land at 60 mph. Of course in a full scale one can feel how the craft is responding and take action [hopefully before you crash] to pick up a little speed or give it a little throttle ,or maybe a little of both. But in the RC world you don't have the luxury of being on-board to feel the pulse of the craft,which maks it hard sometimes to act before it is to late. The idea of crow looks to me like a great idea. That would be almost as good as a parachute being deployed. Back to the flaps. When coming in for a landing[full scale,Cessna 152] you slow the plane to around 80 mph ,then give it say 10% of flap ,you have to drop the nose a lot,at some point you put the flaps all the way down for the slowest landing speed. With out flaps you would have to fly 70 or 80 mph to avoid the posibility of a stall to close to mother earth. In short ,if the wind is calm you could land a 152 with full down flaps at 40 mph + a tad for mistakes. But with out flaps around 60 mph. See the difference? The model in question I am certain would respond in like manner.
