Dis-Regard the reverse throttle issue as it has been solved .. but not the M1 issue ...

[parichya.gautam]

and yes , wire to the AUX  port too set-up . AUX value set at 0 along with the others at receiver test . What is the AUX port for BTW ? Ive set up with the ' SW A ' dial on the upper right of my Tx ...

I think im talking to myself here

Update : I tried flying it , but twice the prop holder flew away and the prop jumped ! ... after many tries finally changed the props and now there SEEM to be fixed ( lost one of the washer in the process and managed to get a minute cut in a prop )

The issue now is .. THE QUAD WONT FLY !!! it shows movement only after the throttle is at 70% ...

I NEED HELP !

Anyone ? ...

Ill  re-ask the query L


I'm in a dilemma here i started building a quad 20hrs ago ( My first quad ) . Initially had some issues but ironed them out now .. the only issue which doesn't seem to go is that when i give throttle to the quad :

1> Its starts moving only when he throttle reaches around 70% .

2> When it gets enough thrust and starts lifting , it tilts to the right side ( both the motors ) .. I have a KK 2.0 LCD Board and i haven't tweaked anything ( except for setting it to Quad X Mode ) , everything is the way it has come ( In sense of the PI Gain and other stuff i dont know what it means )


I need help here ...

I dont have experience with KK 2.0 board but here are few things you should take care.

1. Calibrate your ESCs. This is important so that all your motors behave in same way.
2. Set your prop direction as per manual.
3. Most of the time you have to control quad manually as it takes off the ground. It often have tendency to move in any of the direction and you will have to correct it manually using tx.
4. Try to balance your qaud at CG as perfectly as possible so that it wont deviate much as the time takoff.
5. Make sure your props are well balanced.


Even if after calibrating ESCs your qaud lifts of at 70% throttle, that means your qaud is bit heavy for your motors. It should still fly. But Ideally quad should lift off at aroudn 40-50% to have better control during flight. try to see if you can reduce weight of your frame.

1 - Done
2 - done
3 - even as hard as i try it just doesnt take off straight ..
4 - hmmm , mine is poorly balanced ill try this , but should the board be able do the counter balancing via the sensors ??
5 - Props .. on it

[parichya.gautam]

tried everything .. nothing seems to help .. does NO ONE has any idea !

[Dharmik]

Gautam can you post your complete setup?

[parichya.gautam]

i have a video i put here , one can see the stuff i have .. still , ill upload some pics too .

[parichya.gautam]

Something i would like to add :

I was reading on another forum that TILT is a thing and so is FLIP-OVER ..

Well , as suggested my another member , i gave my quad one good full throttle thinking perhaps it will overcome the tilt and get in the air ,,, well , it FLIPPED OVER and landed on the prop-adapters edge ...

Any help from this ?

If the FC mounted as shown in the above pics then it is wrong. Mount it properly on the frame and then calibrate sensors again. It will resolve your issue.

[parichya.gautam]

it wont fit properly in the frame ( the holes arent at the correct place ) ... what's the issue here ? I have a sponge like material under the M.Board ( gives support , acts as the insulator for the bottom solders and reduces vibrations ) plus by using velcro it is really sturdy ...

Shall i still try and mount it the other way ?

[Dharmik]

The reason is
It is not horizontally leveled with the frame.
To much foam will confuse sensors to understand and calculate small tilt angle as a result it will flip on the side.

[parichya.gautam]

ok...point noted...i'll do that.

[parichya.gautam]

Still happens .... Can NO ONE HELP ME ??

[arun.sreelakam]

What is your problem right now? Not getting armed.? Or is it flipping/ rotating while throttling

[parichya.gautam]

everything solved except for the FLIPPING of the quad ..

as VC said quads dont like to stay at ground so i gave one good full throttle and i just flipped and landed upside down on the prop adapter ...
but once it did start flying ( albeit was still tilting to the right side ) .. so i tried pushing it more and trimming so that teh tilt could be counter-acted ( the point where the battery slipped and the quad crashed 4 stories down )  ..


Thus is my issue ... Mainly FLIPPING .. but twice it was just tilting ...

I cant seem to solve this issue ...

Set all controls to ZERO in the RECEIVER TEST option everytime before you fly. This should stabilize your quad. Also make sure that you have the stability switched on and the PI values tuned. I flashed my kk2 with v1.5 firmware and my quad flew with the stock settings! Lastly, Don't forget to balance your props. Cheers! 

[parichya.gautam]

i recently balanced my props
all settings at 0
mine is running 1.2 firmware , shall i flash newer one ??
stability switched ON from where ? and what changes to make in the PI values ??

[parichya.gautam]

THE RECEIVER GOT BURNT TODAY !!!! ... FlySky FSC16b or something like that model ...

What do i do now   can i use any other receiver or same frequency

[parichya.gautam]

I have this one ..

Parichay, whenever you get back the system up, you might also want to check the following. This is basic stuff but it always helps to be double sure:

1. Your motor directions according to the layout (cw and ccw based on the layout shown on the kk)
2. Your prop rotations (RH and LH placed correctly and all throwing air down).
3. Are the props tight, and not slipping on the prop adapter
4. Ensure motor screws and frame screws are tight and there is no play.
5. Motor should speed up when dropping the arm it is mounted on
6. The motor layout, quad-x config
7. Use zip ties to mount battery etc *tight* so it does not slip again. Of course ensure best possible CG balancing. Ground effect should be gone about 6-8 feet with that quad size. Why were you flying at 4 stories height or were you on the terrace
8. Check for vibrations as well. since you've already balanced the props, *take them off* and place the quad on a smooth surface such as glazed floor tiles or a glass table and give full throttle. The quad should not skid a lot because of vibrations; A little here and there is alright.

Also, like Dharmik mentioned earlier, the FC does not seem axis aligned. This will cause yaw and orientation issues at a later point in time. You can use a spirit level indicator to check level. Pretty inexpensive and available at your local hardware shop. Also, does your quad flip in a split second or it starts tilting and ultimately flips over?

I am not an expert with quads, but here are just 20 cents (2 cents seem less for the rant above )
