How about this. I heard this idea proposed by Burt Rutan at Oshkosh. He 
intends to use it on his next aircraft.

Mount a strain guage on the main wing spar. By measuring the deflection, and 
corellating to some know airflows (use a wind tunnel, strap the model to the 
roof of your car, etc) you can calculate the airspeed.

This will not work in a stalled configuration, but what does? (Doppler I 
know, but anyways...)

Good Luck and let me know how it turns out.
