RC India

Hello,
This is my first quad. Received all the items excluding battery and GPS. Unfortunately Malaysia Post lost the parcel. Hobbyking has started an investigation. Hope it'll come very soon.
Thank you Chintal sir for the radio and ESC.
If I've made any mistake please help me.  :help:

Ready for first flight.

Weather is good today, good luck.

Bad morning for me.
cannot understand the reason it flipped over during the take off.
Checked the things before take off:

1) GPS 3D lock
2) Armed
3) motors started spinning at same time

But one thing i want to mention  there was a lot of vibration when the motors were spinning.  I think the this is because of the long legs and little heavy setup(apprx 1kg).

Nope, that's not the reason.
It's because all Props are not mounted the correct way.
I see 3CW and 1CCW props in the image!

Please make sure that you mount the props the correct way and that the motors are spinning the correct way.
Take help of some YouTube videos here.

Sir the prop are in correct orientation. 2 R marked and 2 L  marked in opposite direction.

may be i have done something terribly wrong. i was testing the quad in my room. i found that the motor no. 4 (motor numbers are according to APM wiki i.e. 1-4-2-3 clockwise) started spinning first then 1, 3 respectively with slight raising the throttle. after 2-3 sec 1 and  4 motors started spinning faster without any throttle movement. motor 2 remained static until i raised the throttle little more.  :help:
 

The 6th image from the 1st post have props mounted the wrong way.
Can you post a latest image showing the current setup?
BTW,  have you calibrated the ESC's yet?

Sir those are not for purpose.
Uploaded the latest snaps.

i have done all the calibrations again including APM. still no result.
Compass data ( 260.851, 22.171, 202 )
Accelerometer ( -0.07 0.09 0.36 )

Please check the video:
https://www.youtube.com/watch?v=e4ki_yYyjCk&list=UUWMAkYgQ-vDGIVZ6E9tMepw (https://www.youtube.com/watch?v=e4ki_yYyjCk&list=UUWMAkYgQ-vDGIVZ6E9tMepw)

You can see motor 1 and 4 rotate faster after 2 seconds.
I am using a clone APM (HKPilot 2.7) from hobbyking.

Looks like an Esc calibration problem. The props are correctly fitted.

ESC/Throttle calibration dude.

Sir i have already done that.
Steps:
ESC receiver connected.
turn on transmitter and throttle to maximum
connect the power module
then disconnect after 5sec and then reconnect.

After connecting power with full throttle, you should here a beep, then You throttle down, wait another beep/beeps, then the calibration is done.

Tried everything. reassembled all the components. but no result. it flips everytime during take off. i think the APM is faulty.
i am going to put it on my 450 frame to confirm.

This happened to me when I was assembling my first quad. As soon as I applied throttle it would flip over. My fault was that I had connected the motor inputs incorrectly. I think motor 1 and 3 were crossed by mistake. After reconnecting properly it flew like a charm.
Check all connections, even if you think you did it correctly.

Sir i have attached the pics.
motor orientation:  front left: M4 (CW), front right: M3(CCW), rear left: M1(CCW), rear right: M2(CW).
Please help me if i have made mistake.

Thank you.

The motor connection is in correct. Check here:
http://copter.ardupilot.com/wiki/motor-setup/ (http://copter.ardupilot.com/wiki/motor-setup/)

Front Left is M3
Front Right is M1
Rear Left is M2
Rear Right is M4

yesssssssssssssssssss.
it is flying.

thank you everyone.
thank you rcindia.


i am sooooooo much happy today. what a terrific mistake i hd done.

thank you again.

Congratulations linked.

Happy to help :hatsoff: :hatsoff:

You ahve learned a big thing today, so which ever controller that you use you should always refer its wiki or documentation for all details like

Motor connectors, RC connections etc etc.

thank you sir.
i really really was so much worried.
thank you.

 :hatsoff: :hatsoff:
yes sir.

thank you.

Well done, and happy flying.

have same frame S500 from HK with Turnigy D2830-11, 30A BlueSeries ESC + prog-Card, APM 2.6 + GPS-Comp and 10x4.5 SF Props..
everything is assembled nicely now just need 12 female bullet connectors for ESCs ASAP..but its look like its not possible to get connectors by tomorrow. so i need suggestion that should i wait for connectors or just solder ESCs directly?
i need up and flying this quad for AF for 'NAVRATRI' festival.

regards,
Bhumin

i think that'ld not be a good idea.
contact satya sir (quadkopters.com).

I cannot ship it today, you can talk with Sphere Hobbies they are based in Gujarat they might be able to do so.

Actually many people suggest to directly solder esc to motor as the bullets may stop working.

thanks..
i asked Mr.satya only for connectors.. but its not possible for him to ship it today... any ways its look like i have no other option then wait for 1 day more.. :(
placing order right now..  :thumbsup:

sir, then the motor rotation must be checked first. right?

good luck.
in my experience LHSs are the best options. sometimes prices offered by HK are better, but you have to prepare yourself to face some problems as well. i placed 3 orders on HK. one parcel was lost in transit and for another one i received a show cause letter from customs commissioner.

Why do you need to do it linked sir i dont understand

sir, if i want to change the direction, two joinings between esc and motor must be interchanged.

i placed order at quardcoptors.com only..
also i am a frequent buyer of overseas online shop and has never face any notice or duty from customs. you just need to consider some basic regulation rules during placing overseas orders and have some PATIENCE... as example. my order of "Frsky TARANIS" from HK came through without any duty. ;) ;) :thumbsup:

DT700 motors are great. today i put a digicam on my quad. just 50% throttle and the quad is up.

The video isn't good. lot of vibration as i mounted it directly on the frame. next time i'll use vibration damping balls.
