Something to consider. The Futaba and JR systems have the battery polaritys opposite from each other. A student of mine had both and was having problems blowing fuses because he would plug in a futaba charger cord into a JR or vice versa. That really messes up a day at the field. He eventually went with JR and sold the other gear. Decide which format you like and stick with that one. Now starts the whos best argument. For the average flyer, they are all good in my opinion. Also, I heard of a guy test a rec by rubber banding it to an orbital sander for a vibration test. It worked. But sounds like it could be a destructive test to me. He had a big chunk of foam rubber between the rec and the orbital surface.
