MGM 16018 Cutting out at 1/2 to 3/4 throttle

Thanks for the info.
I have it set for 9v cut off. the battery is at 11.7V only because I have been running around with it for a while trying to figure out what was going on.
Fully charged they are about 12.6V from memory.

The battery is a maxxamp battery.
I get the same problem if I go from 0- full throttle slowly or stright away.

I have just ben going over my instructions again last night.
It appears that I have missed a step in the programing ( programing by transmaitter)
Apparently I have to set the Automatics tunning when I have done everthing else.
It tells be to run the car at full throttle for a least 2 seconds.

Could this be the problem why I am not getting full throttle?

I can't try it out today as it is raining. will have to wait untill it clears up a bit.
