- no response from servos

I'm trying to bind a new plane: simple high-wing trainer, rudder-elevator-ESC. Tx is a Spektrum Dx6i, Rx is AR400, ESC is Skywalker 40A, rudder & elevator servos are Hi-Tec HS-311.
I've bound a couple of other planes using the same transmitter and one of those had near identical electrics, the other being a Radian Pro foamy; I didn't have much trouble binding them. With this latest plane, I followed the instructions in my Spektrum handbook and in the leaflet that came with the Rx: first time, I got the throttle working fine, but the servos just moved slightly - then nothing further. They don't do anything. I tried re-binding, and this time I can't even get anything from the throttle... I thought this was supposed to be simple & straightforward!
What might I try? All suggestions welcome.

It is difficult not to get so close while binding Tony, but hold the Tx away as far as you can
Tx is off
Rx has fresh battery connected, put the bind plug in bind
And the power lead immediately next to this
The orange RX led starts flashing.
Hold the DX 6i trainer switch and switch on Tx to bind screen away from the RX

I fear your problems are not exclusively binding. If you got the throttle working then it did bind, The fact that the servos didn't work is due to something else.
Suggest you disconnect all the servos and just bind using the ESC (I assume you are using its BEC) on the grounds the less that is connected the less can cause a problem.
If it binds the it is bound and should never need doing again with that model number on the DX6i
Just a point. Is the AR400 DSM2? In which case it will not work with a later DX6i which is DSMX only. The earlier ones (like I have! ) could do both.

Are the other servos plugged in the right way round? All ground and signal leads should be facing the same way.

Was there an old model in the memory when you bound the new plane into the Tx? That might account for the lack of surface movement. You could wipe that model number of all old data and start afresh.

I have been caught a couple of times by different ESCs which appears to be a RX binding fault. the ESC needs a lower than standard throttle low position to complete its setup sequence.
I have needed to set the throttle trim right down and then the ESC completes it sync, interestingly this can affect the fail safe on the motor cut, so trim throttle to low and re-bind.
PS when bind n fly works its great, when it doesn't its just a case of sequentially working through the bind/set up process in a logical step wise way (as described by other above). Hope that helps

Gentlemen, thanks for your helpful contributions. I took the plane & Tx round to Stan Yeo at Phoenix Products and as usual he was very helpful: he connected his own battery, went through the same procedure as I had (as far as I could see), and binding succeeded with throttle + servos working as needed. It beats me...
