RE: How many of you use HAM Ban radios?
I have flown on nothing but ham band for over 10 years now using both JR and Futaba radios. I have flown all over the west coast from San DIego to northern California as well as in Arizona, Nevada, and Illinois. I have flown ham band in giant scale aerobatic planes, giant scale gliders, electric gliders, and thermal duration gliders. I have flown out in the country and in crowded urban areas and at fields with virtually nobody and contest environments with 300 people. I have NEVER had a single problem caused by errant interference. I got shot down once by a guy who never bothered to check the pin board since he figured he was the only ham in town.
BTW, there are several sources of small ham band receivers. I recommend FMA. I use them in small electrics with great success.
