Your description of the receivers leaves a lot to be desired. Forget about 72mhz and go with the crowd.

Should I switch them out with 2.4 receivers or leave them and buy a 72mhz transmitter. Also will the servos fit all makes of receivers. I am overwhelmed by all the technology and varieties of radios. Thanks for any input.
