Hi Colin,

I know someone who has issues holding the weight of the transmitter in their left hand and is unable to operate the sticks on a standard transmitter due to the same issue. It's really awkward to hold upside down and if you hold it in your right hand the wheel is on the wrong side. I've found a few that it is possible with, a couple of the Spektrums are reversible but they're very expensive.

We're going to try holding a standard pistol grip at 90 degrees and operating that that way because I have one at work, hopefully it does the job.
