The Tamiya Attack 4YWD-2.4GHz 4-channel Digital Proportional Radio Control System is specifically designed to be used with Tamiya's line-up of vehicles that require a four-channel radio system.The Tamiya Attack 4YWD uses 2.4GHz radio frequency technology that eliminates the need to use frequency crystals which allows hobbyists to operate their vehicle worry free from interference from other RC cars in the vicinity. Specifically, the technology used in Tamiya's Attack 4YWD-2.4GHz is (Frequency Hopping Spread Spectrum). As the name implies, the transmitter signal of the FHSS system literally hops from frequency to frequency in a pseudorandom sequence. The combination of frequency hopping with the transmitters advanced algorithms creates 100% frequency security. The FHSS technology also offers extremely low latency, exceptionally fast frame rates, and the Tamiya system has no external antennas on both the transmitter and receiver units. The internal receiver antenna along with the compact size make for a clean and clutter free installation to any of Tamiya's large-scale products.If you are looking for a spare receiver for your Tamiya Transmitter, you can use a Futaba R204GF-EFeatures:Compatible with Tamiya 1/16 Tanks, 1/14 Semi-trucks and 3-Speed trucks (with or without Multi-Function Units)Both Transmitter control sticks use centering springsAnalog trimIncludes 4-channel receiverOperating Voltage: 4.8 - 7.4VReceiving Range: 230' (70m)Battery Failsafe: 3.8VCurrent Drain: 30Ma (at no signal)Size: 1.38 x 0.91 x 0.35" (35.1 x 23.2 x 9mm)Weight: 0.21oz (6g)Transmitter requires 4 AA batteries
