Tbh I've been really busy, not had much time to fly anything and with conditions being crap, hopefully in the new year I'll have some new projects on the go, mostly to do with HAM radio, will certainly fly again soon. FTR I hate FB too   :D Merry Christmas

SK450 KK2.2 v1.6 Won't take off.

Hello, I';m new to the RC world so I';m sorry if I make a fool of myself (won';t be the first time) :embarrassed

I bought the SK450 quad from HK with the KK2.1 and Turnigy 5X controller plus two Zippy compact 2200mAh 25Cs in december.

I flew it the first time and experienced the wobbles/ oscillations so I bought the flash tool and flashed my ESCs with SimonK firmware which solved the problem.
My quad flew nicely and I was getting the hang of it so I fitted the FPV gear (Predator V2 kit from HK) but didn';t use it due to no spotter. It still flew nicely despite the pilot.

I recently tried to fly it again and I had a problem with the controls (I thought it was the transmitter';s trims which I had moved during transit which I struggled to reset to 0)
The quad was still very hard to control, veering off to the right and forwards with self level both on and off. Props were on correctly as I had labelled them 1-4 along with the arms.

I then did a factory reset to try and resolve the issue and followed a couple of youtube videos to correct the settings.
I also performed an Accelerometer calibration using a level across the motor mounts around all four sides.

Now when I do the receiver test the max throttle is at 59 and it won';t lift off the ground.

Here are my settings at the moment-

Mixer Editor

Thank you for any help, I just want to fly again  :embarrassed

For a start, get rid of v1.6 original crashware (as it is known) Get Stevis firmware before you do anything else. If your quad won';t take off it is generally because you have the props on wrong or it is not wired correctly. OR, maybe you haven';t calibrated the ESCs?

I can';t remember my 450 settings off-hand but yours don';t look too bad, however I can check against mine if you wish. It would be later in the day though.

Sounds like the esc need calibrating again do this through the kk board
hold down buttons 1 and 4 when powering to get to the esc calibration




hope it helps

Carbon Tricopter with KK2 mini because you have to own a Tri and Falcon Evo FPV (rebuild again) with fatshark 600mw vtx & pz2040 cam. New addition (hidden from the missus!) 250 quad.

As panther said, flash it with Stevies, once you have done that, things will be so much better.

How will that increase the throttle range above 56 ???? agreed the firmware update is a good idea and will improve the overall flight characteristics when the current problem is resolved!
