Ever since OpenTx was released I have been using the same model definition for a Radian that I fly regularly in one of our single model type competitions. This has been used on several 9X, a 9Xr and two Taranis radios. A while back I upgraded the new Taranis to 2.1 but did not fly any model with it until Monday. When I powered off after launch at 200m the aircraft went into a shallow dive, unusual for this particular model but the more I applied up trim the more it dived until I reached max trim (thanks Amber) and it was inverted. The combination of insufficient elevator travel and flexible pushrods resulted in radian digging a bit of a hole in the neighbours just planted wheat crop, and me with a plastic bag of bits.
On investigation I see that the elevator trim, when pulled back for up trim, makes the little graphic block move toward the front of the radio, normally down trim and so it seems I thought I was applying up but was in fact applying down. When I look at the same model in my as yet not upgraded to 2.1 Taranis, the block moves back and applies up trim as expected.
So somewhere in the conversion process I have screwed up by failing to check an option or something. I have converted about 20 models and don't want the same thing to happen to one of my $3k gliders so I need to find out what I have done to reverse the trim and fix it. I can't see any obvious "reverse trim" setting but it must be there somewhere. Would someone please advise what I should be looking for?

Never mind, I found the answer. Turned the elevator trim board up the right way. Sorry.

You might have a reversed stick. I believe the trim was correct but the stick was reversed by mistake. That is why ersky9x has this kind of options protected with a key combination.

Re: How do I unreverse my trim?
Not in this instance, when I removed the rear I discovered that the elevator trim board had been installed upside down by the factory. I had another radio to compare with.
