How to set up a SCISKY FC and get it in the air
CF = Cleanflight, don´t forget to press save in each tab after making changes and before switching to another tab. In CLI type: save and then press enter.
DO NOT PLUG IN USB AND BATTERY POWER AT SAME TIME, YOU WILL FRY YOUR BOARD (MAYBE).
TRIPLE CHECK POLARITY BEFORE PLUGGING IN A BATTERY, YOU WILL FRY YOUR BOARD IF POLARITY IS REVERSED!!
solder on motor plugs and battery lead. Check for correct polarity of both.
Plug in via usb (no battery at same time) and connect to CF.
After 10 sec. red led is flashing fast (=bind mode).
Bind with tx (before set tx to dsm2).
I just turn around to bring my body between fc and tx. Then power on tx while holding bind button. Always works 1st time.
Binding could also be done without connected to CF. Just power FC via usb or battery and wait for fast flasing red led.
Go to CF configuration tab.
Mixer: Quad X
Enable motor stop.
Set minimum throttle 1000, mid throttle 1500, maximum throttle 2000, minimum command 1000.
Failsafe throttle should be lower than your min. throttle (lowest throttle stick input, see receiver tab ( me using 990-995) to make sure motors stop when signal is lost, this avoids flyaway. (Failsafe has an seperate tab now).
Receiver mode should be RX_Serial, serial receiver provider should be SPEKTRUM1024.
Go to CF receiver tab.
Look if stick inputs work in correct directions, if not revers channels on tx.
Set min./max. stick inputs that each channel shows about min. 1000 / max. 2000 and centered 1500.
You have to raise travel adjustment in tx for each channel/stick. On my dx6 I raised each channel to -/+ 147 to get the above mentioned min/max values.
Set rc rate and rc expo how you like it. Stock Scisky is 0,9 and 0,65.
Go to CF modes tab.
Press add range to assign a switch and channel (aux1 or aux2) to enable angle and horizon mode by setting the grey bars to the range where the green thing moves when toggling selected switch.
If no mode is set it’s in rate/acro mode. Say if green thing isn’t in the range of angle or horizon it’s in acro mode.
Go to CF CLI tab.
Type: set motor_pwm_rate=32000 (others use 23200 for 8.5mm motors, 22000 for 7mm); press enter.
Not necessary, but good to counteract jittering of channels in receiver tab:
type: set deadband=6; press enter and type: set yaw_deadband=6; press enter.
After those mentioned changes don`t forget to type: save; press enter.
Go to CF PID tuning tab and choose PID controller you want (read here in forum about these) and adjust values and rates (on left side) to your likings.
You can set up 3 different profiles (don’t forget to set up rc rate and rc expo in receiver tab and set up modes for each profile). Profiles can be changed by using stick commands, no connection to CF necessary.
Calibrate acc in setup tab if you have installed Scisky onto frame.
Frame and Scisky have to be level. (It’s also possible to calibrate acc with stick command when not connected to PC but powered with battery; for stick commands see picture below).
Disconnect Scisky and plug in Battery (TRIPLE CHECK POLARITY BEFORE PLUGGING IN A BATTERY!!!).
Wait till green led stops flashing and turns off (gyro calibration).
Arm it by stick command, fly it.
Side note: motors only spin with battery power not while powered via usb.
Don’t trim via tx. Trim FC by using stick commands.
red: fast flashing = bind mode; solid = bound and ready to fly
green: solid = armed; off = disarmed; flashing = gyro calibration, moron threshold
blue: on = acc active (angle and horizon mode); off = acc inactive (rate/acro mode)
If you reversed polarity and had a magic smoke encounter see here to fix it.
