i bought the CC BEC for my hitec 7950th servo and set it to 7.2v with my castle link. im running 2x 2s 5000mah 40c thunder power lipos with the stock traxxas 4 channel 2.4ghz radio. i had the BEC installed at my LHS by the same guy that i have solder all my rc stuff. i know the connection to the batts are good cuz the bec gets hot. and i know im not over powering the bec cuz its rated to 9v. i have only ran the truck with that bec 4 times, about 5-10 minutes each time and it has worked great until now. all the sudden the truck stopped, wheels stuck turned, not responsive. i opened the rx box and had no light on the rx. so im guessing i gotta send it in and wait for a new one rather than just exchanging it at my LHS... but i only hear good things about CC customer service so it should be a hastle right, besides the hastle of my brand new bec going fart....
