18mz, I have tried others but futaba is my favorite. They are slow on new things but they make good stuff. Telemetry is slow but they are getting there, I would suspect the next flag ship radio will have most of the telemetry stuff. Only thing I care about it fuel telemetry, the rest is just fluff for me.
thought about Jeti but it's to expensive to switch and they need work on how they market.
