Nighthawk 250, Skyline32 FC and Cleanflight giving me issue with ESC calibration

G'day, I'm at my wits end trying to get my nighthawk 250 off the ground. I can't seem to calibrate the ESC's. Have tried cleanflight method but only get motor 3 to power up and the other 3 start but drop down to min. Another strange thing is that motor 3 throttles to max even if the throttle is 1/4. Have calibrated using the transmitter per ESC but result is the same. Am I not plugging into receiver correctly? When looking at receiver in cleanflight everything works perfect and motor spin and throttle correctly for pitch, yaw and roll ( even though they don't sit at same speed I assume because I can't calibrate them). Would really appreciate any input as I just want to get this thing in the air please help out a drone bro......

 

Does that mean you have tried this?

 

Hey mate
Thanks for the response.
Yep, have tried that on all 4 but no change. In cleanflight I can use the throttle all motors and they are all in sync. When I use the transmitter I get this
If you can think of anything else to try I'll be happy to do it as I just wanna get started.
Thanks

 

Don't know what to tell you. Do note having the quad just sitting there with no props and the motors running is always going to result in some bizarre behavior.

You seen this?
