I am in the market for a Turnigy 9x TX to use on a new F450/550 I will be ordering. As this is my multicopter I don't want to shell out too much cash thus the low cost TX. My only worry is losing transmission and the quad comes crashing down. I understand that a FrySky upgrade for the T9x provide a fail safe mode and also extends the workable range. Anyone with experience with this? is it a worthwhile upgrade?
Thanks
