A few reasons,

- I dont like the ergonomics of the trasmitter. I generally like to hold my trasmitter more horizontally than vertically and the Dx6s screen then points away from me. It also doesnt feel as natural to me to hold.

- It doesnt have a seperate channel off the joysticks that allows variable control over a channel unlike the futaba 6ex which has channel 6 variable

- The receiver whilst being small is far to fragile. The pins look far to easy to bend unlike the futaba where they are protected. I am not running an ant weight so a bit of extra box around the receiver doesnt give me any head aches.

- They refer to the channels on the Tx and Rx as flaps, rudder etc. Fantastic if you have a plane. An extra headache to work out which channels to use. With a futaba its always channels 1 to 6 and beyond. Nice and simple for any model to use.

- The sticks on the transmiter are too stiff for my liking.

- They can say all they want that it is easy to program. Took me a good half hour (with the manual) to figure out how to put mixing between two channels. With a futaba I am done in seconds without the manual.

- The problems that gave me a real headache at the UK champs were not from my speedos as I had thought but from the spektrum.

The only thing that I feel that it has going for it is that I can control my bot from 150m away. Not a major advantage as futaba now have a 2.4ghz version of the 6ex. I dont believe it has failsafing on all channels but I cant see it being long before they have the option.

So if anyone from futaba is reading this then please get in contact about sponsorship
