I have given up. Re- caliberated transmitter. Downloaded firmware. Reduced this and that and still gets hesitant. The first minute or so all is well, on a fully charged battery. Then it drops off. The batteries still have plenty of ummf, in fact last another ten minutes from this time.
On advice i have knocked back lipo cut off as far as possible (6volts is lowest it will go). Now what....I am not that stupid but am feeling that way.
FYI is the same for med acceleration/timing and the quick 'higher settings'.
Help
