Guys, just a heads up, we have checked range issues on many occasions, the most common cause is bad quality batteries either in the car (if nitro) or the transmitter. I dont reccomend using budget AA batteries nor the long life duracells as they dont give the power, the may show good voltage but under load do not perform. also on the older Syncro radios you could change the mode from F to G, but has to be on both RX and TX!!!! this ups the power in the radio to give better range. FYI F was specific for France where they had power output restriction on 2.4!!! apart from that damaged RX antenna is next likely, lastly if the TX is damaged by dropping or got wet! I hope the RX fixes the problem Skip!
