I have recently swiched radio from JR 12X to Futaba 12Z. The setup is the same as it was on the JR radio, but about a few minutes into the flight the ESC cuts - resulting in an auto.
I have reversed the throttle channel on my Futaba, and am running straigt curves on the stock controller (Hacker X-70 SB PRO).

Any input is highly welcomed as I am tireing from doing autos...

Thanks

Did you check to see that zero is zero on throttle channel, some radios have a bottom reserve you must extend to be actual zero..

...Once upon a time there were Nitros, flybars and frequency pins...

Esc cutting out has nothing to do with the radio, the hackers do cut out when you overamp even slightly, we've tried heatsinks etc but really the only solution that worked was to pinion the motor down (smaller pinion)Apart from that they work well on the smaller vbar (400 class)machines

Hi Stolla, and thanks.

What bothers me is that run the exact same setup as I did when I used the JR, but after the switch the ESC has started to cut...

I have now gone thru the setup once more, and will try again this afternoon. Of corse I will report back.

So far, thanks for all help

It's possible that for instance your throttle curve is a little different, i.e I had situations where lower headspeed can draw higher amps under load so if your headspeed is different it may be but otherwise just coincidence i think

Recheck your headspeed - it may well be a bit different
If it's higher that may explain why you cut under load
It means you were always close to the limit
Adjust your Futaba TX throttle curve
to get the same headspeed as the JR TX

Does the X70 calibrate to your TX throttle range?

If indeed it's different headspeed causing cutout i'd say you are too close to the limit anyways so pinion it down to be safe.
To give you an idea i we eagletreed a 400 converted to 10 logo the other day on 16 vs 15 t and dropped 15 amps!
