This is my 2nd ZMR250 build, with this one I decided to try the Diatone ZMR250 Power Distribution Board Ver1 (Ver 2.1 has issues) so I can use both 3s and 4s Lipo’s and DYS SN20a Opto Esc using the PDB to power the flight controller as well as handling the voltage requirement for my FPV System. The BL20’s come flashed with BLHeli so I can run one shot with active braking which should improve the performance of this quad.

The ZMR250 frame is one of the best low cost frames on the market and has more accessories made for it than any other frame out there so you will have almost infinite options to customize it the way you want.

My  CLEANFLIGHT Setup 1.10.0 + PID Controller = 1

 

Some of my Initial setup commands and settings.

feature vbat (only if you us a buzzer for voltage alarm)
feature motor_stop (I don’t like motor spinning after arming, so I enable it)
set looptime = 2500 (~400Hz)
set feature ppm (only if you use ppm receiver, 1 servo lead)
set align_board_yaw = 90 (only if board is rotated to the right for easier USB cable reach on mini  quads)
set telemetry_inversion = 1 (required if you want Frsky telemetry)
set frsky_vfas_precision = 1
set deadband=6
set yaw_deadband = 6
set emf_avoidance = 1 (increases processor speed)
set acc_hardware=1 (disables your Accelerometer sensor use if you fly Acro only it disables horizon/angle modes)
set auto_disarm_delay = 10
set pid_controller = 1 
set gyro_cut_hz=75
set pterm_cut_hz=45
set dterm_cut_hz=14

Don’t forget to SAVE or your changes will be lost!!!!

That’s all my personal preference, change it according to your liking.

For a more detail CLI command list, check here.

Calibrate ESC

As these are flashed with BLHeli I didn’t calibrate these using cleanflight all calibration was done using the blheli settings.

BLheli

If your not using BLheli flashed ESC’s

TAKE YOUR PROPELLERS OFF while working with the quadcopter.

You’ve been warned!!!

Open Cleanflight and select the motor testing tab then select the box next to the master slider to allow motor control.

Raise the slider to the top before plugging in your lipo. Plug in your lipo and wait for the calibration tones once you hear these lower the master slider all the way. You should hear the calibration finished tones.

Check if the calibration is successfully by checking if each motor spins to the same input. (Remember do not mount your props when doing the testing.)

FrSky Telemetry Setup

1 Connect your FrSky receiver (like the d4r-II) to your Flip32/Naze32. Connect the External analog telemetry Rx port of your FrSky receiver to RC input pin 6 on your Flip32/ Naze32

Connect to your board using Configurator and select the configuration tab. Select Softserial & Telemetry then hit SAVE.

3 Select the ports tab on Configurator and then under Softserial1 set Telemetry to Frsky & Auto

Select the cli tab on Configurator and type the following commands

set telemetry_inversion = 1
set frsky_vfas_precision = 1

then type save

Select the Settings Tab and plug in your Lipo, if you have done everything correctly your voltage should be displayed. Adjust your voltages on the config page to line up with what your actual voltage is.

That’s it for now will add to this post as I have time and am able to Maiden .
