Pete,

Not sure if these guys are still going - last web update looks like 2012

What is the exact model of the receiver you have - what other number text does it have on the case apart from 40/41?

All the instruction manuals in PDF format are available on the site

Looks like the LED is indicating "glitches"

CAUTION: all this sophistication is no guarantee for problem-free flying.
 If you fly close to the range limit, or even at close range if the aerial is poorly positioned, a problem may arise which the receiver automatically corrects, leaving you unaware that there ever was a problem.
That is why we have also installed a reception quality indicator LED.
 The receiver counts the invalid transmitter signals it picks up, and informs you of the number of errors by a pattern of flashing.
 1* flash = 1 glitch (2 to the power of 0)
 2* flashes = 2 ... 3 glitches (2 to the power of 1)
 3* flashes = 4 ... 7 glitches (2 to the power of 2)
 4* flashes = 8 ... 15 glitches (2 to the power of 3)
 5* flashes = 16 ... 31 glitches (2 to the power of 4)
 6* flashes = 32 ... 63 glitches (2 to the power of 5)
 etc.
We suggest that you experiment with various arrangements of your receiving system and power supplies in the model (receiver position, aerial position, receiver battery position, flight or drive battery position) and read off the glitch count after each test flight or test run. In this way you can establish the optimum installation of the components in your model by adopting the configuration which reduces the glitch count to a minimum.

Is there a pattern to the LED flashing?

I think it might be worth removing and reseating the crystals in both transmitter and receiver

Nope just flashes away as soon as tx is switched on, regards pete
