I am no expert at this...but I use the Turnigy i10 radio and also the FS i6A 6 channel RX - (I have 5 in use coz they cost a lot less than teh bandits at HobbyKing want in overpriced shipping for Turnigy stuff)
Binding the FS RX seemingly is always a game of - wait and see!
I never get any confirmation its worked during the bind process - I do using the TGY iA10 .
I doubt its peculiar to me - but I found once that after getting pigged of with the apparent lack of success binding the two..I gave up - shut everything down and went away to kick the cat for looking smug ( not really)
However a couple of hours later I went back - turned it all on and pushed the stick to arm the motors...and it did!
Now I go through a game to fool the radio and RX.
first I choose bind 1 way - close everything down.... give it a couple of minutes - then start up and change to bind 2 way. Usually I get no joy and pretend to go away sulking again. Having fooled the radio and RX... I go back after a while and lo and behold...its a winning bind and all is ok!
It may not work for everybody - but it does seem a game to get a bind -whether its about draining capacitors or waiting for the logic chips to agree the settings or finish their lunch I am not sure - but honestly - the shutdown seems to act as a cold boot!
IF the RX is a steady red LED - showing you have a bind - but it appears NOT to arm the motors - I suggest you go back into LP and check the OUTPUT tab and see if the sliders have gone back to zero. Is so reset them and SAVE. I find that sometime doing any changes with the radio or going through the TX setup - can knock all the setting back.
I have got to the point when after any change... I go though all the tabs to check them and save each.
Yesterday on a new build 250 build - with which I opted to use a 250 template and whatever setting up I did...Channel 4 YAW was changes to read channel 6 - which is my flight mode channel on the Radio - but test flights showed that that the stick operated normally and yaw - was yaw!
I started again and went through Vehicle SETUP from the Welcome screen - ignored the template option and stayed with my setup - everything back to normal and at this time seems to need a bit more attention to tuning!
I don't know if the channel 6 thing was due to the radio, RX or glitches in the Radio setup, the template or gremlins in the works.
But now if I have anything not going right - changing bits here an dthere can get confusing..so I just upgrade and erase and start again making sure I do it right!
There are 100s of post on RC Groups about the binding problem - not seem to get a straight forward solution. I do it my way after that one instance of going back to find all was OK.
So I suggest you give up fighting the errors and try my way - if it does not work.... you have still lost nothing trying - except a few minutes on LP
