At the events its clearly dominated by spektrum although this whole receiver mess and now the DX20 mess has allot of us pretty upset.
They stopped making one type receiver to release another then recalled it.... So many of us had to scramble and go through hell to try and get a receiver before Florida jets. Also I saw 3 planes go in with DX18s. Jack Diaz has his transmitter turn off and back on while in flight resulting in the loss of his F86 that has been flown year after year at events including topgun. Then my friend George lost an ME262 in a certain spot on the field. He thought it was the plane then lost radio contact with his aviation design diamond the next day in the same exact spot. I am guessing his RF board is bad.
Spektrum better get their act together because allot of us are making a mass exit. If I had the money I would be flying Jeti for sure despite their marketing that I don't like. When it comes to the best radio system its it. I will never go back to Futaba while the RF link was great they suck ass at updating and bringing new stuff to the market. Also didn't care for how they ignored Kingtech when the factory was trying to get with them for telemetry on the new engines. Looks like the factory figured out their protocol anyway so that will be good for futaba users.
Currently using 2 DX18s. One for me and one for my son. So all this is from a DX18 user and a former Futaba user.
