Creating a brand new mannequin on an EdgeTX radio transmitter on your FPV drone is easier than you suppose. Whereas many brand-new radios include a preconfigured profile for quadcopters, studying find out how to arrange a brand new mannequin from scratch is extremely helpful. On this information, I’ll stroll you thru the method step-by-step.
The interface and steps might range barely between radios with monochrome shows and people with shade screens, so I’ve offered directions and screenshots for each varieties.

Checking Default Channel Order
Earlier than creating a brand new mannequin, it’s vital to make sure your radio’s channel order is ready up appropriately.
By default, the default channel order must be AETR, you shouldn’t change it except what you’re doing. AETR stands for Aileron, Elevator, Throttle and Rudder, it principally means:
- CH1 is Aileron (Roll)
- CH2 is Elevator (Pitch)
- CH3 is Throttle
- CH4 is Rudder (Yaw)

Making a New Mannequin
In case your radio doesn’t provide a mannequin setup wizard, it’s not an issue, the radio will create a generic mannequin profile. You’ll be able to set it up from scratch following the directions beneath.
Set Mannequin Title
Professional Tip: you could create separate profiles for all your FPV drones. Nonetheless, when you’ve got many drones like I do, that’s lots of work and might be tough to keep up. As FPV drone pilots, we don’t usually want to alter mannequin settings, subsequently I have a tendency to simply create mannequin profiles for the completely different radio hyperlinks I exploit. For instance, I’ve one profile for ExpressLRS, one for Crossfire and one other for Frsky. Every of those profile is certain to a number of fashions which might be utilizing the identical radio hyperlink.
That is simply my suggestion, it’s completely as much as you ways you handle your mannequin profiles, there isn’t a unsuitable or proper manner.
I’ll simply name this mannequin “ELRS” which stands for ExpressLRS.

Checking Inputs
There are two pages it’s essential to configure for channels: Inputs and Mixes.
The Inputs web page is routinely arrange by the system, however it’s a good suggestion to double-check. This web page can be utilized to switch uncooked management inputs earlier than being mapped to completely different channels within the Mixes web page – resembling including expo or adjusting weight on the uncooked enter values, however that is sometimes utilized by fixed-wing pilots who don’t use a flight controller. You’ll be able to study extra in regards to the goal of the Inputs display screen right here: https://oscarliang.com/inputs-mixes-outputs/#Inputs-The place-Management-Begins.
In the event you solely fly multirotors, you’ll be able to normally skip this display screen, as there’s no want to alter something.
Configuring Mixes
Within the Mixes web page, you’ll be able to map inputs to channels. Radio techniques typically have 8 to 16 channels accessible, for instance, ExpressLRS helps as much as 16 channels. The primary 4 channels (CH1 to CH4) are at all times used for the stick controls, and the remaining channels are for switches, often called Auxiliary channels (AUX).
The channels are setup routinely by the radio primarily based on the default channel order (as we confirmed earlier in step 1), so usually you don’t want to alter something right here. Nonetheless, it’s a good suggestion to double-check to keep away from any surprises. In case your default channel order is AETR, the Mixes ought to present:
- CH1 Aileron (Roll)
- CH2 Elevator (Pitch)
- CH3 Throttle
- CH4 Rudder (Yaw)
To study extra about channel order, what it’s, and find out how to change it manually, you’ll be able to comply with this information: https://oscarliang.com/channel-map/
Swap Configuration
You will have to configure switches for arming the drone, flight modes, and beeper.
That is how I usually use my switches:
- For Arming: Any 2-position change
- For Angle/Horizon Mode: Any 3-position change
- For Beeper: Any 2-position change
- For added options, resembling turtle mode or return to dwelling: Any 3-position change
Now, go to the Modes tab in Betaflight Configurator, and assign the AUX channels to the features you wish to use. Observe that:
- AUX 1 is CH5
- AUX 2 is CH6
- AUX 3 is CH7
- AUX 4 is CH8
- and so forth…

Binding to ExpressLRS Receiver
Now you’ll be able to bind the drone to your radio following this information: https://oscarliang.com/bind-expresslrs-receivers/
Telemetry Setup
Telemetry is beneficial for monitoring very important flight information, resembling battery voltage and GPS coordinate (when you’ve got a GPS module put in).
Fashionable radio hyperlinks resembling Crossfire or ExpressLRS they each assist Telemetry.
To set it up, go to Betaflight Configurator, Receiver tab, and allow the Telemetry output choice.
Finalizing Mannequin Setup
ADC filter is barely wanted for fastened wings and not using a flight controller, it will possibly easy out RC instructions and scale back jitter actions in servos. Nonetheless, it will possibly introduce extra latency to your controls, which isn’t supreme for multirotors, Betaflight has its personal built-in RC smoothing anyway, so ADC filtering isn’t wanted and must be turned off. You would additionally depart the choice at International (default worth) and handle it from {Hardware} web page in Radio settings.
Listed here are another elective options that I usually configure in my mannequin.
Arm Timer – the radio says the time each minute. Timer 1 begins when the arm change is activated. It helps me maintain monitor how lengthy I’ve been flying for.
Listed here are the particular features I’ve. One perform is for studying battery voltage out loud utilizing a momentary change. The opposite perform is for resetting timer 1 when the arm change is deactivated.
Earlier than your first flight, totally check all controls in Betaflight Receiver tab, with out plugging within the LiPo battery. Confirm that the management course, arming change and different auxiliary features work as meant.
It’s vital to make sure yaw, roll and pitch sticks at middle place are precisely 1500, and all these channels, in addition to throttle, can attain a minimum of 1000 and 2000 at their finish factors. A little bit decrease than 1000, and better than 2000 is ok (e.g. for the bottom, 988, and for the very best, 1012, are each acceptable. In any other case, you aren’t utilizing the complete vary of your controls, and it is best to repair it within the Outputs web page on the radio by following this information: https://oscarliang.com/adjust-tx-channel-mid-end-point/
Backup Mannequin Profiles
As soon as you’re proud of how your new mannequin profile is setup, it is best to again it up.
Following directions right here to backup and restore fashions and radio settings: https://oscarliang.com/backup-restore-models-radio-settings-edgetx/
Conclusion
Congratulations! You’ve efficiently arrange a brand new multirotor profile in your EdgeTX radio. The setup might be not probably the most intuitive for newcomers, however it’s a strong radio system, the deeper you study this technique the extra you’ll be able to obtain. All the time guarantee your configurations align together with your particular tools and wishes. Secure flying!
