No Expo on Rudder on Specktrum DSS???

Not at all...

Exponential (Expo) merely regulates the sensitivity of the travel of a given channel in relation to the amount stick input.. Control can be set more radical with a small amount of stick input, or it can be set to "soften" the control movement around center when stick input is given...

We flew for years without it....

That concerned me too, as of late I'm flying small 3D models with huge rudders. In actual use, I've found it to be a non-issue after flying a HellRaiser (Depron foam Ultimate bipe) and Straight Edge (profile foamy Edge) with the Spectrum. Spectrum focused on the RF design to get their system to market ASAP. The Tx box and baseband electronics are OEM from JR, essentially the same as the JR622 (which is likewise lacking rudder expo). A few guys that prefer the newer and glitzier JR6102 to the older 622 have pulled the RF deck and antenna from the Spektrum Tx and replaced the 72Mhz RF board in the 6102 with it. Only takes splicing 3 wires to swap in the new RF board and a little trimming on the plastic case to accommodate the antenna swap. Reportedly about 10 minutes work. I guess for those guys rudder expo means more than it does to me!

Personally, I NEVER use expo on a rudder anyway, and only very rarely on the elevator.

I DO use expo on the ailerons of almost everything I am flying

The only people who need a precise and geared down rudder are serious aerobatic fliers.

I'd say its not an issue that bothers me..

Ditto. I DO use it on elevators for models that have a high speed range. And need a lot of UP to land...but not a lot to do screaming huge loops in the sky..and may tip stall if forced to do high G corners at high speed.

dual rates will do that for you expo wont make any difference as it wont stop you pulling full up

Is there dual rate rudder on the Spektrum? mk

Yes, in an unconventional way. You set up a mix switch for rudder-to-rudder. It is described in the manual, for wusses that RTFM.

Yeah..it will, but I am lazy...too lazy to flick switches :-)

Placed an order for Spektrum DSS today.

Thanks everyone for sharing their opinions.
