I have 2 of the tekin 432
When you hooked up the power to the 432 you have to have it also plugged into a receiver
There is a small on off switch that comes on the tekin
This switch is to turn power on for the receiver so you will not need extra batteries for the receiver
You must turn this on
When this switch is on and you have turned on your transmitter there should be a small red light in one corner of the 432 on
You should be able to pull the trigger on your transmitter now and the motor will spin
If it does not there are 2 small screws under water plugs in the top right corner you will have to adjust , easy to do
Give it a try , it all has to be plugged together or nothing will work
