Hi kinggeordie.......... Do you have pictures of how you did the sound generator for the U2540? and which micro switch you used? We are also building one and could use the help............patsy
yes heres a pic of the switch and servo the module is mounted under the reciever, it uses the tube to amplify the sound, so far so good, i still need to test it at distance and may need to put a small amplifier in but ill let everyone know after she has been in the water....
