A compact receiver choice for users who prioritise a solid radio link and straightforward installation in a wide range of RC models.

Is antenna trimming safe on the RX381?

No. Cutting the antenna is likely to reduce reception quality. Keep the antenna length as specified and route it cleanly.

Which voltage sources will run the RX381?

The RX381 accepts 4.8V to 7.4V, so standard receiver packs or a stable BEC are appropriate choices depending on your setup.

Can the RX381 be used in small scale models with limited space?

Yes. Its compact 37.5x24.7x14.1mm size and 8.0g weight make it suitable for tight radio bays in many 1/10 and similar scale models.

How do I avoid interference from other electronics?

Keep the receiver and antenna away from heavy motor wiring and metal masses. Use ferrite beads and tidy cable routing to reduce electrical noise when necessary.
