Can anyone help? I have two new servos after trying two older servos. They are S3003 Futaba. I want to use them with either my Airtronics AM 75 transmitter and 2 channel reciever or a MEGAN TECH Lunior Transmitter with a KO PROPO AM reciever.

When I try them both the do not seem to want to make the servos move. I know both transmitters and recievers work as I had them in different cars prior to trying them with these servos... Any ideas?

Or are these servos even compatable with the gear I have?
