I am setting up a Trex 550 with VBar 5.0. Set up is straight forward just like the first one I set up in my Henseleit Rigid a couple of weeks ago. So, here's the problem, I had to reverse the pitch and aileron servos but then collective wouldn't work the right way so I had to reverse it. I changed the aileron servo ports and got the collective going the right way. This went back and fourth a few times with elevator getting reversed and put back to normal as well. I got it all working the right direction but when I move the machine to check for proper correction from the VBar roll corrects properly but elevator is correcting backwards. When I put the nose down the VBar corrects with more forward cyclic. I've been setting up machines for years but this one has me a little miffed.

is your sensor lined up like in the reference picture? Sounds like you may just have the wire going forward or backwards of where it wants you to is all. That or you simply have all the wrong servos in wrong ports, reference the manual there, it shows you what should go where.

...Once upon a time there were Nitros, flybars and frequency pins...

You have servos plugged in wrong is all. Create née setup in vbar to wipe it and change servos.

You also might check to make sure your settings in the transmitter tab of the Vbar program are correct. Pay attention to the direction the stick is moving compared to what the software sees.

Correct, most likely the aileron and elevator servos are plugged in wrong, I did the same thing going by the 4.0 software manual, and like said above, in the TX calibration menu, make sure right aileron shows up on the screen as right aileron, as so on. So change those 2 servos if the calibration menu is correct, do some more reversing to make everything respond correctly with the transmitter, and the vbar should compensate correctly
