Tactic receiver question

[bigkahuna]

Just new to sport and learning more, we have three TTX240 TX, was wondering if there is a updated or aftermarket receiver that can be used instead of the Tactic TR324, the transmitters seem fine and have had three RX's fail. We always make sure we use the proper start up procedure. Both myself and son have had issues with the Tactic TR324 RX's, one failed in the hobby store, when shop expert tried out the boat before we left the shop. For those following my UL-1 problems, tested the Esc, it was the problem, ordered new one. Thanks All!

well here's what happened to me. I was testing my used servos with a tactic tx/rx, and came to plugging a servo in rx and red light went out. I tested another servo and plugged it in and light came on. The servo shaft was hard turning and drew to much juice, so I cut the wires off and tossed servo. I use Futaba 3003 servos with super success.
