My guess would be they use variable resistors for encoders. I haven't done servos for a while, but the industrial stuff all used optical encoders with Gray code patterns.

There are bit more expensive servos with proper encoding. The thing is hobby airplanes don't need high precision as pilot controls looking at the whole plane movement. Now that hobby is killed by regulations. Robotics is coming..
