had to do Stuarts Core Tx the other week after he blew up his esc and they are a pain, they are a one button push and hold then wait for lights!
1) Press set button and turn on the Rx switch hold button and wait for the light to go solid red.
2) Full throttle and wait for light to turn solid green.
3) Full brake and wait again
4) Back to neutral position and wait again for light to go solid
Then switch off and hopefully it has set first time!
