RE: Polk's Hobbies radios?
A guy at my field and I bought several of their receivers because we liked the idea of changing frequencies at the touch of a button. Out of the four we bought between us, every one of them ended up going back to Polk for service do to poor range checks. I got discouraged with them and went back to Futaba synthesized receivers with zero problems. He finally lost a plane do to glitching and has replaced his Polk receivers with a more reliable brand.
