The Futaba 3PV Radio System is sophisticated, powerful and easy to use. Pick up the 3PV and instantly feel how lightweight it is. Once you access the programming menu on the easy-to-read screen, you will instantly recognize how sophisticated the programming is. But the real experience happens when you get to take advantage of the 3PV's super-fast response rate. This is a system that can make a difference on race day. You also get FHSS, S-FHSS and T-FHSS protocols, making it one of R/C's most versatile surface system. This version of the 3PV with R304SB telemetry receiver (FUTK3200) is for those that want to keep an eye on their receiver voltage. But the 3PV is also available with a high-voltage R203GF receiver (FUTK3201) that is perfect for brushless ESCs and digital servos.
