Quad still wont take off properly.

Hi Mate I would if you can get some that are flashed with simonk or BLheli they will work better watch this video
 
There all sold out right now and out of the country lol Ill have to wait on them.

So I've got some info that I need to get some input on.
I have successfully got the quad to fly in the air for about 20 seconds before I lose control and land it lol
(things aren't as Easy as i thought they were to fly lol)

SO here is my issue I'm having.
When I arm the FC and start giving it a little throttle I notice something odd. I just give it enough to start all the motors turning.
After about 15 seconds, its strange, but the #1 motor starts to rev up a lot higher while the other 3 stay the same.

Other issues I need to work out is when my quad is in the air, I cant seem to get a solid hover, also going forward and backwards is pretty smooth but going left or right, barely moves the quad.
I'm sure its some setting on the FC

Going to try and get video but need a friends help.
 
Hi mate sure your getting 100% travel on the sticks in the FCB if not use servo travel adjustment in the transmitter , as for motor one not sure but recheck zeros in the monitor screen see if the number keep jumping , if this is ok look at the min throttle setting in the KK ,menu/ misc/settings min throttle
 
(Using version 1.9S1 on KK)

My KK wont let me access the "Sensor Max Min"
If thats what you are talking about.

I have a couple pictures I took of the setting on the KK and one kinda stuck out.
It will be attached below.

On the menu called "output Sliders" it looks like this shows you how the motors are calibrated to each other or something.
But when I apply half throttle on my radio, the KK shows that they are not all staying the same.

 
Believe it or not, I got it to fly somehow! i tweaked with the setting somehow and its flying.
Ill go ahead and reflash the KK with the 18s1 so its correct though and report back with how it works

Very excited right now though!
 
Brakes are ON for two motors and for other two they aren't.
so you gotta reset the ESC settings and recalibrate it.
and also and I think YAW isn't stabilized..otherwise it would have resist rotation.
 
Hi stabilised does not work that way it's a gyro so if an input comes from the transmitter it allows the movement if from wind etc it will hold position
 
Im not sure what you guys talking about there with brakes on the motors and what not lol

Anyways. So I still need to get a video for you guys but yea its flying decent.
Im getting about 10 min flight time with a 5200mah battery. That sound about right?
Charges to about 11.1v and when it dies its at about 9.4v
Anyway to increase the flight time?

Can defiantly tell that the ESC are not correct for this type of quad. You can tell its a bit flaky. It is very jittery at times.
Looking at buying these ZTW spider 30a ESC

Also I cannot get a proper hover with this. When flying I can get close. Ill have it to a point where it slowly descends. I touch up on the throttle one click and it slowly ascends.
So it wont do a proper hover.

2 more questions.
Is there a way to set a warning beep on the FC to warn you about the battery dieing?
Also what is this setting on the FC about with the self hover?

EDIT: whats better, BLheli or SimonK

Some people prefer one some the other. Depends how your flying. The ESC braking function means that the magnets create resistance like FET drag to slow the motor down when you cut the throttle, on a racing quad controlled by a great pilot this is perfect, but for a beginner this will cause you more harm than help.
 
Its off hobbyking but Im going to get some different ESC's first before I reprogram anything.

But about the battery, how long of a flight time roughly should I get with a 5200mah battery?
Its a Multistar High Capacity 3S 5200mAh.

Also is there a way to have a warning on the radio of something on the quad to warn you when the battery is going to die?

be sure to get the 3S1P instead of the 3S2P (unless your getting 4S then get 4S1P).

The KK2.1.5 has a voltage buzzer, you'll have to get a lead off from the power distriution circuit and take the + to the + pin where it has red header and says batt + -.
 
I just checked the batteies i own and just bought.
The one ive been using is this one
https://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=66475

I just bought these as well, another one for this quadcopter and 2 smaller one for a 250 im gona build now.
https://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=57364
https://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=58955

There all 3s1P.

So take a + lead off the distribution board and attach it to the + side of the buzzer on the kk? and then just keep the ground attached to the kk board?

NOT the buzzer, there are two sets of headers, one black (buzzer) and the other red (voltage alarm). you also have to set the voltage alarm.
