Any corrections/updates/advice appreciated.
Your picture of the trainer jack on page 6 doesn't quite match my HK 4 ch radio.
Your pin#2 on my radio is a No Connection - not +5v
Your pin#3 on my radio is +battery output - not signal input
My radio matches this schematic (all though, with different pin numbers)
Your 6 ch turbo seems to be wired differently than my HK 4 ch.
Hope this helps.
