Hey at my age I need all the help I can get big fella!
Any-road-up....mission accomplished!
Swapped the wires across and did a reverse at the TX, the hardesr part was working out what the HK set-up box was telling me.
The figures a percentage your limiting and not the otherway round???
Throttle 20% is limiting throttle by 20% and 20% of throttle available......or not!
But its up and running. Time for a rest, its been a rather stressful day
