User: Can I bind my Radiomaster tx16s transmitter to two receivers at once, to expand available channels

Can I bind my Radiomaster tx16s transmitter to two receivers at once, to expand available channels

Assistant: Short answer: No — you generally cannot bind a single RF link from your Radiomaster TX16S to two receivers at the same …

Short answer: No — you generally cannot bind a single RF link from your Radiomaster TX16S to two receivers at the same time in order to “expand channels.”

Here’s why, and what is possible instead:

📡 Why You Can’t Bind One Transmitter to Two Receivers for More Channels

• When your TX16S binds to a receiver, it creates a single radio link using one protocol (e.g., ExpressLRS, FrSky, DSMX, etc.).
• That link carries whatever channels the protocol supports — but it’s not split across two receivers the way a computer might use two USB ports.
• You cannot bind the same RF link simultaneously to two different receivers in the same protocol to combine their channel counts — the transmitter will only maintain one active link per protocol at a time.

Some transmitters and protocols can talk to more than one receiver (e.g., DSM2 with multiple binds), but that’s for independent control (like flying two models separately), not for combining channels into a single model.

✅ What You Can Do Instead

1. Use a Receiver with More Channels

If you need more channels, the simplest solution is a receiver that already supports them (e.g., 16-ch SBUS, Crossfire with more outputs, etc.). Your TX16S can already output all of them to one receiver.

2. Use a Protocol That Supports High Channel Counts

Modern protocols such as:

• ExpressLRS
• FHSS/AFHDS 3
• FrSky ACCESS

…support many channels inherently — often more than older protocols like D8/D16.

3. Daisy-Chain or Split SBUS

If your goal is to feed two flight controllers or components from the same radio link:

• Many receivers output SBUS or CRSF which can be split to two devices (using a simple cable splitter), but both are getting the same channels, not “more channels.”

4. Use an External Module + Multiple Protocols

The TX16S can host multiple protocols (internal + external module), but:

• You still bind each one separately to a receiver.
• You won’t combine them into one model’s channel count.

Example:

• Internal module bound to an ExpressLRS receiver for your aircraft.
• External module bound to a DSMX receiver for something else. They’re independent links.

5. Use Telemetry / Smart Port

Some receivers allow additional data or configuration through telemetry, but this doesn’t add channel outputs beyond what the receiver provides.

🧠 Why This Isn’t Like USB Ports

Think of your TX16S as having one radio conversation per protocol at a time. You can talk to many devices in the same family (e.g., FrSky telemetry/share), but you cannot stitch two separate RF links into one bigger one.

📌 Summary

| Goal | Possible? | Notes | | ---------------------------------------------------------- | --------- | ------------------------------------------- | | Bind TX16S to two receivers at once to combine channels | ❌ | RF link doesn’t aggregate channels this way | | Bind TX16S to two receivers independently (for two models) | ✔️ | But you control one at a time | | Use one receiver with more channels | ✔️ | Best solution for more outputs | | Split SBUS to two devices | ✔️ | But same channels are shared |

If you tell me which protocol you’re using (e.g., ExpressLRS, FrSky ACCESS, etc.) and how many channels you actually need, I can suggest the best receiver or setup for your exact situation.
