⚠WARNING⚠
These EdgeTX model memories are offered as-is, should be understood as recommendations and may not suit every pilot's needs.
Only use these files if you downloaded them directly from www.omphobby.com. 
Model files hosted on 3rd party websites are entirely outside OMPHOBBY's control.
OMPHOBBY has no control over, and assumes no liability for the use of these EdgeTX model files and the products used with these files.
Always consult the OFS3 User Guide found on omphobby.com for instructions on safely operating OFS3 equipped models.
These model files may be updated without notice. Always check for the latest version on omphobby.com.
Installation instructions can be found on the internet, and vary by radio.

Transmitter Models: 	EdgeTX Color LCD or Monochrome ELRS Transmitter
Transmission Protocol: 	ExpressLRS (These files are NOT compatible with S.BUS or DSM outputting protocols)
EdgeTX Version: 	2.11.2 or later
ELRS Version: 		3.5.6 or later
ELRS Settings
	Packet Rate: 	333Hz Full
	Telem Ratio: 	1:4
	Switch Mode: 	8ch
	Model Match: 	On (Recommended for safety, set your receiver ID accordingly. Default is 0)

Installation Notes:
	• Color LCD users place the .yml file into their SD card's MODELS folder and rename it from model##.yml to an unoccupied number. 
		•For example, the user may have model1.yml, model2.yml and model4.yml, then the file may be named model2.yml or model5.yml
	• Monochrome users place the .yml file into their SD Card's BACKUP folder and restore it into a free model slot on their transmitter.

General Notes:
	• These model files represent OMPHOBBY's recommended settings for use with OFS3 in the M2 EVO MK2 and M2 V3 PRO.
	• Both model files are compatible with both Proportional Throttle and Software Throttle modes.
	• Warnings use telemetry return for indicating the model's battery status to the user.
		⚠ Your receiver's RX must be connected to OFS3's TX for this to work.
	• These setups are designed to utilize an arming switch for added safety.
	• Timer 1 is set up to count upwards, for you to evaluate your total flight time. 
		•Timer 1 starts and stops with the motor. 
		•Timer 1 is reset upon disarming.
	• Used battery capacity and voltage can be called out anytime by toggling a momentary switch.

Customization Notes:
	• All switches are defined in INPUTS. Each input is used throughout the model file. Do not change switch assignments anywhere else.
	• Switch directions can be reversed by changing Weight sign in INPUTS (-100/+100). 
		⚠ Do not reverse channels 5-9 in OUTPUTS under any circumstances. 
		⚠ Do not change INPUTS weights away from 100.
	• Expo is not enabled by default, it is recommended to set expo through the OMPHOBBY app.
	• Percentages for Proportional Throttle RPM1, RPM2 and RPM3 can be changed in MIXES under the corresponding CH6 lines, by changing their Weight.
	• The pre-set Proportional Throttle values correspond to 60% (3720 RPM), 75% (4650 RPM) and 85% (5270 RPM) in Software Throttle mode. Refer to the OFS3 User Guide for throttle mapping.

Telemetry Notes:
	• Default telemetry warnings are set for the M2 EVO MK2's and M2 V3 PRO's 3S 750mAh battery:
		• Used capacity over 635 mAh: Capacity will be spoken every 5 seconds with gentle vibration
		• Voltage below 3.3V per cell (9.9V total) for 1.5s: Voltage will be spoken every 2 seconds with harsh vibration.
	• A telemetry screen is already set up with useful information:
		• Instantaneous and minimum battery voltage
		• Instantaneous and maximum battery current
		• Instantaneous and maximum rotor RPM
		• Battery capacity used and ESC temperature (Monochrome) / Instantaneous power and peak power (Color LCD)
		• Color LCD ONLY: Top bar displays mAh, full battery voltage, temperature, and minimum link quality
		• Color LCD ONLY: Additional screens show throttle% vs. RPM, vehicle attitude, ELRS data, channels and model info.
	• To reach the telemetry screen:
		• Monochrome: Press the TELE button on the main screen
		• Color LCD: Page over to the right once for power info, twice for RPM info, three times for attitude info, four times for ELRS info 
	• Telemetry resets automatically upon battery swap, or more precisely, when telemetry connects successfully.
	• Warning thresholds can be customized in Logical Switches. 
		• L20 triggers the voltage warning
		• L21 triggers the capacity warning
	• Telemetry warnings only activate when ARMED and the motor is ON. Warnings are disabled if the model is disarmed or the motor is off, or both.

Miscellaneous notes:
	• Trims are intentionally disabled.
	• Rescue Mode and Attitude Mode occupy the same channel. This channel is mapped to two switches. 
		• Use the switch appropriate for the mode enabled on your model.
	• A model image for M2 V3 PRO in orange is included
	• More model Images for Color LCD can be found on https://www.skyraccoon.com/aircraft/OMP-Hobby_M2-EVO-MK2_OMP-MK2-O
		• OMPHOBBY is not affiliated with AIR-RC. We do appreciate their work though!
	• The Color LCD model file features some additional screens:
		• Throttle percentage and rotor RPM side-by-side
		• Vehicle attitude and control channels side-by-side
		• ELRS transmission instantaneous performance and extremes

Default switch assignment for Monochrome, default optimized for RadioMaster Zorro:
	• ARM (ELRS Arming)	SE (Switch away from user is ARMED)
	• THR (Throttle)	SF (Switch away from user is FLY, towards user is OFF)
	• ATT (Attitude Mode)	SC (Switch towards user is ATTITUDE MODE)
	• RPM (Rotor Speed)	SB (Switch towards user is HIGHEST RPM, applies to Proportional Throttle and Software RPM)
	• TEL (Speak Telemetry)	SD (Switch depressed speaks used capacity and voltage once)
	• RSQ (Rescue Mode)	SA (Switch depressed triggers Rescue Mode auto-sequence)

Default switch assignment for Monochrome, default optimized for RadioMaster TX16S:
	• ARM (ELRS Arming)	SA (Switch away from user (up) is ARMED)
	• THR (Throttle)	SG (Switch away from user is FLY, towards user is OFF)
	• ATT (Attitude Mode)	SC (Switch towards user (down) is ATTITUDE MODE)
	• RPM (Rotor Speed)	SE (Switch towards user is HIGHEST RPM, applies to Proportional Throttle and Software RPM)
	• TEL (Speak Telemetry)	SF (Switch towards user speaks used capacity and voltage once)
	• RSQ (Rescue Mode)	SH (Switch towards user triggers Rescue Mode auto-sequence)

Enjoy!
