Best Radios for INAV 2024

INAV only requires a very simple model setup in the radio, just the 4 control channels plus a few mode switches. 

You can get by with just about any radio system including RadioMaster, FrSKY, FlySKY, Futaba and Spektrum as long as the receiver can output a serial signal using a protocol like iBUS, SRXL2, SBUS or CRSF.

My preference is for radios that use the EdgeTX operating system and ExpressLRS RF protocol. EdgeTX is the most flexible and programmable operating system and ExpressLRS gives the most secure and long range RF link.

Spektrum and FlySKY operating systems are less flexible and more locked down than EdgeTX.

Below are my top suggestions for a good INAV radio in 2024

Note: EdgeTX, INAV and ExpressLRS are all RC Community developed OpenSource projects so they are often updated and  will require a little more research and experimentation to master than traditional locked down systems like Spektrum.

ExpressLRS Radios

1. RadioMaster Boxer ELRS  (or Boxer 4in1 with ELRS RF Module) 

The Boxer is a very reasonably priced radio with plenty of switches. One momentary, one locking, two 2 position, two 3 position and one 6 position switch as well as two pots. It has a full sized JR RF module bay. The only things missing are sliders on the sides. There is a large battery bay for 2S LiPos.

2. Zorro and TX16S are good options too, although I am not a fan of the colour touch screen version of EdgeTX on the TX16S. 

My daily radio is actually the Zorro 4in1 with Ranger ELRS RF module. The game controller form factor is not to everyone's taste but I like it. It uses 18350 Li Ion batteries which are hard to find and have less capacity. But I like the side sliders for panning cameras and also crow braking on gliders. 

The TX16S would suit someone who wants all the bells and whistles including a large colour touch screen. But I find it unnecessarily big and heavy.

3. FrSKY TaranisQ X7 with external BetaFPV or RadioMaster ELRS RF Module

This is FrSKYs cheapest radio and it was my favourite for many years. I love the rotary selector dial and overall feel.
It only binds with FrSKY ACCESS and D16 receivers unless you add an external ELRS RF module.

ELRS Receivers

Any ELRS receiver can be used with any ELRS radio or module

RadioMaster RP1, RP2, RP3, RP4TD ELRS or any of the PWM receivers with Serial output enabled

BetaFPV - ELRS Nano, Lite, SuperD and Micro PWM or SuperP PWM with Serial output enabled

ELRS gear has amazing range, at least 5km even with the nano receiver versions. Or you can think of it as very secure RF link for short range even with obstacles. The diversity receivers like SuperD and RP4TD extend the link security even further for extended long range or close range penetration.

SBUS Radios

1. RadioMaster Boxer 4in1 

All RadioMasters radios come in different versions. CR2500 for one chip multi-protocol (Mainly used for RadioMaster and FrSKY receivers), 4in1 with 4 chip multi-protocol, or ELRS.

2. Zorro and TX16S are also good options. ELRS external module can be added

3. FrSKY TaranisQ X7 (only compatible with FrSKY ACCESS and D16 receivers)

4. FrSKY Tandem and Twin radios (Higher quality hardware but more expensive and limited to FrSKY receivers)

SBUS Receivers


RadioMaster R81, R86C

FlySKY iA6B using iBUS or SBUS

My YouTube Playlists to help with the learning curve. It's worth the little extra effort of watching a few videos on the relevant subjects
