OK, I must surely be coming to the end of my questions, now that the heli is built, the electrics are done and I've just completed the mini vbar blueline express set-up! Well, you would think so, but here's another couple of questions if you don't mind 
OK, so I dilligently followed Mr Mel's set-up videos and have bench set-up my Trex 550e by the book - level swash, 90 degree linkages, etc. All as it should be (although I did have to swap out the inner swash ball's for smaller Trex 700 ones to improve the geometry, but I digress).
So, my 2 questions are as follows:
Having exited the set-up wizard and just been playing about with my DX8 to see the servos and blades moving, I've noticed the following.
Q1 - Collective pitch movements are clean and precise. Move the stick, the servos move in unison and stop when the stick stops. But when I play about with some of the other controls, when I release the TX stick and it self centers, I see my Savox servos still moving after the stick stops moving. Not by much and it's very slow - I guess I'd call it servo creep. The servos move to where I presume they should, and the first part of the movement is as rapid as the stick movement, but when the stick stops, the servos creep very slowly for up to, say, half a second. Is this normal? I played about with the 3 different flying styles in the software, but that didn't seem to make a noticeable difference. I have straight curves at the moment, no expo.
Q2 - Having exited set-up and still playing about, when I move the Tx rudder control my tail servo moves just as it should, but when I release the rudder and the Tx stick self centers, my tail servo remains deflected. This happens whether I give positive or negative pitch to the tail. Set-up was perfect, I selected Savox servos (after you folks pointed out I hadn't done that!!), there's absolutely no binding.
I haven't tried this, but might it work properly if I exited the wizard and unplugged my USB connection to the vbar? I was presuming that once set-up is done, vbar should work as it would during flight, but perhaps it's not in that mode when I'm still plugged into it with thesoftware open? Just a thought.
As usual, all advice gratefully received. Many thanks.
