Help Needed

[halfpint]

I live in north devon in Barnstaple.
Is there anybody who lives in or around this area upto about a 50 mile radius.
Willing to help me set up PROPERLY my hexacopter.
Its a hobbyking h.a.l turnigy 775mm
with a KK2.1.5 Multi-rotor Flight Control Board With LCD, 6050MPU, Atmel 644PA
I cannot fly at all and when i get it working so all the props start at the same time and speed up or slow down as they should.
When i do start to get it to take off, it just flips on its back to the left or the right.
What is taking me ages to do via watching youtube sites or looking on here
someone who can fly and knows how to set up the flight control board will have it in the air in no time.
I want to learn how to do this but there is so many variations on the settings its getting to be a mine field.
Obviously i will come to you and a drink or 2 will be given for your help.

Thanks    Paul........ or text me on  07902951460

Hi Paul,

The first thing I would check is that your motors are spinning the right way, and you have the right props on each motor. The I would check that your channels are set correctly. Once you';ve done that, check back 

[halfpint]

Yes this is how the fc board told me to set it up.
and to make sure you use the right prop i found a youtube vid with a m&m.
and if you have a cw prop, you will have the back part of the prop touching the table and a part inclined this part should scope up the m&m.
and obviously the same principal on the ccw.
sorry if im not explaining it in the right terms but you get my drift.

Now also regarding the channels i have put the corrisponding cable from the fc to the receiver.
But just checking that i still put motor 1 into m1 on the fc board and 2 into 2
and so on?
it sounds stupid asking but sometimes the way we all think its got to be right we find out after hours of pulling out the hair it was wrong all the time.

                                            6ccw       1cw   
                                              +    +
                                 5cw    +           +    2ccw
                                              +    +
                                             4ccw    3cw

also i am assuming that in the fc settings under loading model there is a

hexacopter +  and a
hexacopter *

I am right in saying it is the hexacopter *
that i have to set it to

as they say never ASSUME
as you will make a ASS out of U and ME

Ok, sounds like you';ve got those bits right. Raised part of the prop should go in the direction of the spin. (thats how i remeember it!) Motors in the correct order. What about channels from receiver to flight controller, are you using a single cable or several??

From my honest opinion, I would triple check that the motors are numbered correctly, spinning correctly, and the props. My last build kept flipping till I realised that I had motors 3 & 4 connected the wrong way round even though they were spinning the right way.

[tupoar]

Also, have you calibrated you esc';s?

[halfpint]

I am using a
10 Way Ribbon Cable for Receiver to Flight Controller
so once you connect cables to throttle receiver on fc board you only use 1 cable per channel for your ailerons/rubber/yaw
i also have the 3 motor cables going into the receiver as some have the red lead disconnected.

[tupoar]

Ok, if you try powering up, with just throttle, does it try and flip then? Or is it when you try and use any other movement?

[halfpint]

Yes the way i read this was.
with tx off put thr to full then turn tx on
then this is the fun bit, plug in the battery and then press the outside 2 buttons on the fc board and it should beep.
whilst holding these down put the thr to idle or down and the fc board should beep again.
then let the buttons go.
or i read that you can use 2 cloths pegs which i have tried and its so much easier.
does anybody have any good working fc board settings that they use that i could try.

[halfpint]

I had to think about that one then as im still learning.
I think that it is when im powering up that it suddenly goes into hooker mode and lay';s flat on its back.
obviously being a novice my right hand is also playing with the stick a little bit to try and keep it balanced,

And then its all over in a flash and its start again.

[tupoar]

I would try just throttle, nothing else. If it';s ok then it';s probably your channels in the wrong order ie rudder and yaw is mixed up. Otherwise, it sounds like the motor order is incorrect. I';m hoping someone else will jump in with some ideas...

[halfpint]

thanks for help and advice so far.
im just home from one job and starting another at 5.30 till 00.30
so I will pull it about abit and check the channel settings and motor firing order.

As you are a novice flyer, and you';re using a KK2 board, can you tell me if you';re flying in Auto Level mode or in full Manual.

It may just be as simple as you';re not yet used to the muscle control required. In Manual mode it is up to you to control the aircraft';s attitude. So any kind of drift will need to be compensated by you on the sticks.

With Auto Level mode a lot of that is done for you, allowing you to gain control and confidence. Later switching to Manual it will be easier to handle.

From your replies it sounds like you';ve done everything right in setting up so far. So my thinking is it could just be as simple as this.

My 1st ever tbs disco was flipping on take off. Took me all night to find out what it was. Turned out I was powering up quad before turning my transmitter on. Could this be your issue? If you have the balls you could power hex up whilst holding it see if you feel quad trying to self level when tilting quad or if it tries to tip further in that direct. Other than that check you have right motors plugged into correct ports on kk2. Motor directions and correct prop on each motor. Make sure kk2 is facing forward and close to COG

Funny you saying that,  that';s exactly what I was going to say!
From the rear of your model the screen and buttons should be towards you - if it';s not like that it will be interesting to try and fly to say the least!

[halfpint]

This is one thing I haven';t got my head round yet. It say';s to arm self level you put the right stick across to 3 o';clock and hold then the throttle down to the left.
then it goes on about setting it up in aux to one of the spare channels.

whoosh over my head. Sorry but complete brain fart.

can anybody put it in laymans terms please.

Props:

';R'; props go CW.

Or another way to remember is that motor 1 takes an ';R'; prop and you can work from there.

(Just making sure!)

I did something similar last week in my head the voices were saying no don';t do it and from experiance I new not to do it, but for some dumb reason I turned off the transmitter whilst the hex receiver was still powered on and nearly got a facefull of spinning props.  Ouch big time.

Okay, so it sounds like you';re trying to fly in Manual mode, without any auto-level assist.  Doing this all by yourself is not going to be easy, the voice of experience here.

I';ve forgotten a ton of stuff about the KK2, but there are loads of folk on here who know the FC very well indeed who can advise.

If possible, I';d suggest setting it up to Auto Level by default for now - if that is possible.

[xxpitt]

i';m sureit tells you on the screen what mode you are in when you arm it, has been a while since i';ve flown kk2 though. i never selected modes with stick commands always used the aux channel, set up a switch on your tx and plug the corresponding receiver channel into the aux pin on kk2.

[halfpint]

Well just to let you all know i pulled all the wiring off and the fc
and rec.
and started again.
all rewired and started it up and my first ever fly of an aircraft and I got it
hoovering all but about 3 inches but its a start.
I brought 1 3 200mah hi-energy extreme battery.
but it doesn';t last long at all.
and I know im learning so dithering more than whoosh get up there
but can I run 2 or even more to get me more air time.
or how about a car battery and a long flex just for training purposes though.

[halfpint]

I have also gone and got meself a hubsan x4 quad
with the camera built in to it.
now lets get some flying minutes in.  Hahaha

[Hands0n]

Re your battery - do you mean you have one 3200mAh battery?? Is it a 2S, 3S or 4S (the number of physical cells)?

You can double up batteries, but the flight time gain is not linear because you';re carrying more weight and that eats into the power capacity. 

@xxpitt - The KK2 board does indeed show on its LCD display whether or not auto-Level mode is on or not.  And, like you, I set it to use the Aux channel via a switch on the TX.  In Steveis software you can set Auto-Level to be permanently on if you have zero intention of ever using the full Manual (Acro) mode.  I think thats a nice touch also.

[halfpint]

Yes sorry forgot to say that.
im using a 3cell battery.
as that is what hobbyking said to use on there box.
can I run 2 batteries as there is another connection to plug pos and neg lead into.
also if they say use a 3s battery do I have to or can I stick 1 or 2 4cell batteries in it and run these I stead?

[Hands0n]

You can run less than a 3S battery, but that would result in a rather under-powered multi-rotor. 

Before you attempt to run a 4S you absolutely have to make sure that your Motors and ESC are capable of handling the voltage.  Check each discretely, don';t take it that the components will until you';ve checked.

It is very unusual for a second battery input socket to be fitted to a multi-rotor, unless by specific design.  Usually you';d build one in or fit a Y-cable (parallel, not series) to link up a pair of batteries.

[kilby]

To get the machine 3 inches off the ground how far do you have to raise the throttle (is it around 50%) ?

You haven';t mentioned what motors, ESCS or props you are using.

One thing that will cause a lack of power is then props being fitted upside down.

What frame is it?
