Interesting thread.....My e50 has the DBC/Benedini combo that I got from phil at rctankwars.......I love the sound. The only issueI have is if the tank is not moved every 20 seconds, the motor sound shuts off....If you go to move thetank, it will move but you get the startup sound while the tank is moving( must be one of those new hibread tree hugger tanks).....this was phils first shot with this kit and I have read thatif the card issetup differently you can get around this...the other option is to keep the tankmoving......If you get this setup,I sugest you request the card keeps the motor running if possible.
