Welcome to the forum, Tanmay.

Please give some more information about your set up.
Which flight control board are you using ?
and which radio ?

Are you following this procedure?

If you are using a Mode 2 Transmitter:
1) Power up your Model and Tx
2) Keep throttle at 0 (Left Stick at bottom position)
3) Then move the same stick to the right and hold for 2-3 seconds and the board would get armed. (You will hear a beep from the KK Board Buzzer and the LCD will show "Armed" on it.)
4) If it doesn't works then try moving and holding the same stick to Left (instead of right) for 2-3 seconds.

Let us know the results.

If these procedure fails, you should do a Receiver calibration on your KKK 2.1

Yes sir I tried that many times for both sides it it doesn't work.  How to do receiver calibration?

Post by: SK1701 on February 08, 2015, 01:34:22 PM
Does the kk board say OK or ERROR? Go to the kk 2.1 menu called "receiver test". All the values should initially be 0 (except AUX). When you move your Tx sticks, it should show the correct direction e.g. front, right and "Idle" or "Full" for throttle. Reverse any necessary channels to achieve this effect. Set end points on your Tx so that the max receiver test values are 90-100 and the minimum -90-100. Have you also done the ESC calibration and loaded the correct motor layout?

follow the steps,( After all the motor directions, props etc are correct )
 
1) Place the quad in level surface, Means pitch and roll angle should be zero, If not calibrate Accelerometer, by placing in level surface.

2) enter the receiver test menu, Here you can see the Interpreted value from each receiver channels.

3) Hold the elevator stick to down, the value against elevator should be b/w -100 to -90, If it is higher (>-90) or Lower (-100) Then change your elevator channel lower end position (in Tx) to adjust this to the needed range. Also while you move the elevator stick to down, 'Back' should be displayed against this channel (in LCD), If it is displayed 'Front' Instead of Back, Just reverse your elevator channel.
Now Move elevator stick to High end, and change endpoints to adjust max. value in bet ween 90 - 100 range. (Also it should display Front against this value) .
Now the configuration for your elevator channel is completed

4) Follow the above step for Aileron(Roll) and Rudder (Yaw) channels , But in this case it will be displayed Left or Right according to stick movement instead of front or back as for the elevator channel. Also adjust the min, and max. stick values to fit in the same range as set in elevator. Reverse  the required channels.

5) Now for throttle channel the min. stick value should be higher than -90 and max. value less than +90 . On throttle max, it should display 'full'.

6) Now your accelerometer and receiver are calibrated and set up.

7) Apply 20 - 30 % throttle, quad should not lift from ground .

8 ) Move elevator stick a little forward, back motors should speed up, and hence quad starts tilting to f/w , on moving elevator b/w ,  the quad should tilt b/w .

9) Check aileron and rudder channels also in this way.

10) Now every thing is fine and LIFT OFF  to the skies,  try to hover at one place and apply necessary trims to make it stable.

        If you don't understand any thing, Feel free to ask out before breaking any props ;D

Happy landing :)
 

P.S : Was too lazy to type these again, hence quoted from an old thread ;D

Before going to receiver calibration, Trim your rudder channel, to left side step by step (While holding left stick to downleft corner)

Dose the Propler size matters for lifting the tricopter?


Title: Re: I am unable to armed my tricopter. what to ddo??
Post by: sooraj.palakkad on February 16, 2015, 04:40:04 PM
The propeller size matters dude :banghead:
Which is your motor and battery ? I can recommend optimum propeller size to go for :)


Title: Re: I am unable to armed my tricopter. what to ddo??
Post by: tanmaymh on February 17, 2015, 07:24:45 AM
Motor 1400 kw
Battery 4200 mAh.
My tricopter is not lifting.  Is this happens due to propeller size or the self weight?


Title: Re: I am unable to armed my tricopter. what to ddo??
Post by: sooraj.palakkad on February 17, 2015, 08:37:02 AM
Kv rating only is not enough data to chose propeller . We need to know it's power, if you don't have that information, please post the make and model number of the motor, if you're unable to find that, just post some clear pics of your motor here .
     
               From your first post, I can see you haven't described your problem and set up in detail . One small request, If you are asking for help in any topic, you should make sure to post all the relevant Information that you found is associated with the topic - If you're not sure of something, it doesn't even matter to post the complete details of your build .
     
               I won't blame you for your non-informative posts, as you are a beginner to the hobby, and to the forum .
Now Please post the details of all the things that you are using in your copter, and some pics too

 Consider these : Frame size ,Material , weight .
                        Motor size , Power , Kv rating ,
                        ESC specifications ,
                        Flight controller (You already told it is KK2)
                        Battery  (You told it is 4200mAh, please say what cell configuration, C rating, and Weight )
                        Radio (CT6B)
                        Propeller Size and Pitch

               If you don't understand, any technical terms, and you think you're unable to explain some details, you can take a Picture of that part including labels or wrappers if it is there .

Frame size is 38 38 40 and 2×2 cm block on 40 cm arm for servo tilting.  Material used is wood.
Weight with whole setup is about 900-1000 gms.
Motor of 1400kv 10T. 30 A ESC. Flight controller KK 2.1 .
Battery 4200 mAh 3 cell 11.1 v it is about 300-400 gms.
Transmitter is TS- CT6B. And propeller is of 8×4E. Give me the solution.

Post by: sooraj.palakkad on February 17, 2015, 03:15:27 PM
For a AUW of 1Kg, each of your motor should at least provide up to 700Gm thrust.

Check whether your motor provided that much thrust with a 8x4 prop ?

I assume your motor rotation directions, and Propeller directions are correct .

Post by: K K Iyer on February 17, 2015, 03:48:23 PM
@tanmaymh,
As suggested earlier by Sooraj,
Could you post a pic or specs of your motors?
Are they Turnigy D2826/10 1400kv?
If so, attached Bruce Abbot test data may help you.


Title: Re: I am unable to armed my tricopter. what to ddo??
Post by: tanmaymh on February 23, 2015, 12:13:15 PM
Does the battery voltage matters for the thrust of the motors?
My battery is 4200 mah 3s 20c and motor is A2212 10T 1400KV. And also in kk 2.1 the valuas of aileron,  elevator rudder and throttle are not adjusting to -100 to 100. I try it in pi editor bt doesn't work nothing changes in that value.  Is this also happens due to battery? ??? My tricopter is not lifting is this due to low thrust or weight of itself? ?? Its total weight is 1385gm and body is of wood. Tell me the solution.

Is too heavy for these motors, please reduce weight of tricoptor or change motors.


Title: Re: I am unable to armed my tricopter. what to ddo??
Post by: tanmaymh on February 23, 2015, 01:35:30 PM
How I reduce??? Does change of battery can work????


Title: Re: I am unable to armed my tricopter. what to ddo??
Post by: akhilzid on February 23, 2015, 01:53:31 PM
before that please specify your props here.

for reducing weight:
try with less weighed battery(can be 2200mah 3S 25C or greater)
reduce frame weight (your frame looks too heavy with too lengthy arms ),


Please never ever try to fly with non-insulated wires like shown in the previous post.


Title: Re: I am unable to armed my tricopter. what to ddo??
Post by: tanmaymh on February 23, 2015, 02:16:59 PM
but only frame weight is 225 gms. only frame
not any thing on it


Title: Re: I am unable to armed my tricopter. what to ddo??
Post by: sooraj.palakkad on February 23, 2015, 06:03:58 PM
If the frame weight is only 225 gms, how come the total weight to 1385 gm ???

Check weight of your battery individually . Three of your motors cannot provide the sufficient lift to your Tricopter.

You should consider reducing the AUW to less than 1Kg .

Avoid unnecessary wooden pieces,  decrease the arm lengths, and find some alternatives for that landing skids . you may also consider using aluminum hollow square tubes for arms.


Title: Re: I am unable to armed my tricopter. what to ddo??
Post by: tanmaymh on February 23, 2015, 10:26:32 PM
Actually the the frame weight means only wooden frame without motors esc or wiring.
battery is of 385gms. is there someone who want 4200mah  3 cell 20c 11.1 V battery pls contact 9833536857.

Does the 2200mah 3cell 11.1 v 35 C battery is suitable for the tricopter?


Title: Re: I am unable to armed my tricopter. what to ddo??
Post by: tanmaymh on February 26, 2015, 05:15:20 PM
Does the 2200mah 3cell 11.1 v 35 C battery is suitable for the tricopter?  Or the "C" rating affect for the flight?


Title: Re: I am unable to armed my tricopter. what to ddo??
Post by: Himadri Roy on February 26, 2015, 05:32:26 PM
Depends on your style of flying....if you want to fly aggressively(high speed passes,etc) not sufficient and if you wan to hover then ok....
More C rating means you can withdraw more amps without puffing the battery!  :hatsoff:

I have the similar setup, wooden frames and these nameless motors, the auw with 2200mah is 750gms,  and the copter works just fine, so for your copter to lift or to work properly, you have to reducuce weight to atleast 800gms, and the prop should be 10x4 size. Btw, what lipo and how old is it.


Title: Re: I am unable to armed my tricopter. what to ddo??
Post by: sooraj.palakkad on February 26, 2015, 09:09:32 PM
Tanmay, a 2200 maH 3S 25C or higher is Enough for your setup - But you should really consider decreasing the weight to around 800 gm incl. everything .


Title: Re: I am unable to armed my tricopter. what to ddo??
Post by: tanmaymh on February 26, 2015, 09:10:20 PM
Ohh are you want to buy it? If you want then check out my another post "I want to sell my battery" on that I had given all details. If you want to buy pls contact immediately on 9833536857


Title: Re:
Post by: v2 eagle on February 27, 2015, 08:32:37 AM
No i am not intrested in the lipo as i knew my tri cannot lift that weight. Am getting around 13mins with this setup which i am verymuch okay with. Just want to know the life of battery since my old turnigy 2200mah which holds charge good and voltage as good as a new one failed to give beyond 6mins. So a degraged lipo wont show itself explicitly but you will see a drastic loss in performance, sometimes deadly. Btw whats your auw except lipo. Pics please..and why thismuch heavy, what wood is the arms made of and what about the center plate, my previous versions of tricopter has centerplate that weighs close to 200gms, now my fiberglass centerplate weighs just 40gms, these are the checkpoints that you need to look out for.


Title: Re:
Post by: v2 eagle on February 27, 2015, 08:43:46 AM
Just saw the tricopter pics again, are you using a electric switch? I can see lot of plywood which is not necessary, my arm lengths are so short that the props are just 3inch away from the fc, center board seems okay, sleeve up all the wires, are you using different brand esc on one arm, those motors aint capable of lifting this weight. Are the props rotating in correct dorection. Instead of using ply to lock those legs, just use single screw.
