Jet I Hi-Copter 40 amp ESC

Hi people.

I'm being forced on to another type of ESC as my favourite ones have gone end of life. I'm trying a new set of Jeti 40Amp hi-copter ESC's

Everything is connected as per usual but the Jeti's / engines are not responding at the same time. Some start some judder. However they all run when the throttle is at around 65%

According to my supplier they did a change about a year ago relating to this so by rights these have had the fix.

The setup is WKM Oct with U5 motors. RC Futaba traditional at the moment not S-Bus.

No change if the idle is increased to High in the wookong.

Previously I would time all the ESC's to the rx, do the directions then into the WKM but these Jeti's don't seem to need the throttle response timing doing.

Any help much appreciated.

All the best
