X9303 - spool up in throttle hold

[supercpa]

Help !!
I have a TRex SEV2, with a Jazz 40-6-18 and a JR X9303 2.4 tx.
I just went to a 30C battery and decided to reprogram mode 1 and mode 4 in my Jazz.
Now my heli spools up when I put the throttle hold switch into the on position.
I haven't dismantled my 9303 so I know I haven't re-wired something wrong, but I am stumped as to how to re-enable the throttle hold. I re-programmed modes 1 and 4 a second time, with no change. Can anybody help me ? :confused:

your th hold has a percentage value, change that until no power comes to motor(lower it).

Thank you very much !!
That worked. The percentage was already negative, but not negative enough.
