[spiboom85]

Hi All

my 4 year old son is running a b4.2 rtr now nothing wrong with the buggy but iv had some trouble with my son keep turning all the switches on the top of the transmitter is a xp2g 29215 ae team associated

now on this model I could turn down the power to the buggy by turning the TH ATV down

Now here is my question iv bought the ABSIMA CR3P

Seems a good bit of kit but I cant seem to find a setting that will allow me to turn the power down only has full throttle power,

also I cant get the revere to work I had this problem with the transmitter above witch I just had to a just something on top and it worked fine

hope someone can help cheers ?
