The Tactic TR325 3-Channel 2.4Ghz SLT Receiver is a great choice for boats, cars, trucks, truggies, and buggies — anything that could benefit from a lightweight (5.2g) receiver. Its internal antenna means no wires to route or break. In the unlikely case of signal loss, the TR325 has an automatic fail-safe feature which returns all servos to center, but automatically resumes normal function when the signal is reacquired.
