exactly. All the other code required the servo to read exactly 14335.
Again, run the code yourself!
sorry guys i can't get my head round this.. i thought if i use val > 14335 it would work for any value greater than 14335 regardless of wether the value moves slightly.
pulseIn(rcpin, INPUT);
shouldn't this be
pulseIn(rcpin, LOW);
I think INPUT is defined as 0 anyway but just to clarify the code shouldn't it be LOW?

I never saw any code of the OPs of the form ( (14335 ? val) ?? (val ? 14335)), other than your reply to OP which I thought was a typo and Arrch's misreading of it. Did OP edit his 14335/14535s in the original post?
Again, run the code yourself!
Agreed
Guys thanks for all your help on this, it's late here in the UK so calling it a day. i'll run the code and try and get a better understanding. fantastic forum and thanks for helping me out.
Cheers

Hard to get your head around because you've gotten a lot of ideas, and some from every one of us has been wrong in one way or the other 
You could probably understand better if you broke it up like this?
if (val > 15555){
// joystick is FORWARD
}
else if (val < 14444) {
// joystick is REARWARD
}
else {
// joystick is NEUTRAL
}
I changed the numbers so we would quit misreading 14335/14535

Actually, this is a perfect illustration of why magic numbers are a bad idea.
#define LOW_VAL 14335
#define HIGH_VAL 14535
if(val < LOW_VAL)
{
}
else if(val > HIGH_VAL)
{
}
else
{
}
means you correct an error/erroneous value in one place, and the logic is far easier to see.
Arrch:
if ( 14335 < val || val < 14535) {Can be simplified to
if ( val != 14335) {So you want the LED to be off at that value, and on otherwise? Seems a bit loft to expect it to be EXACTLY that value.
Actually I think that code simplifies to
if (val < 14535) {
Which is still in error, but not that error

Absolutely!
