Friends and I use the PZ module and it works pretty good. The big drawback is where its mounted, on the bottom of the plane. So, We are retrofitting it for the top of the plane. We all just need a company to take a chance and build a generic combat module. It'll happen, hopefully. Perhaps company specific like JR or Futaba? Couldn't it work fine tied to a specific tx/rx? Because I will say this We have had a ton of fun with Our V-tails flying combat. Can you imagine then making it freq specific? Clubs could face clubs! Anyways, sometimes it takes a chance to make something popular.
