@RahulVyas: Lightening fast Thank you

welcome
sometimes internet goes mad

Hello everyone, here is a video of maiden flight of my quad. Also, The doesn't seem to descend down gradually when i reduce the throttle, instead tends to fall.
I suffered a crash on the third take off. Again the esc in the arm one was burnt. I noticed that soon after the crash, one of the wires from esc to the motor was disconnected. Is that the cause for the esc to be burnt or was it the crash landing.
Could you please suggest a way to stabilize the quad for hovering and altitude hold. Thank you. I will be trying KK2 board when the replacement esc's arrive.
Thank you all

It flies nice mate. Keep it up. Just need bit practice and it will be handy.

Looks good Abhishek, little more practice and you are good with it

you quad is in + mode of x mode?

@Dharmik: Thank you sir

@Satyagupta: Thank you sir. The Quad is in X configuration sir.

Abhishek try to hover your quad at one place.. I can see its not in control and landing hard...

nice arun b bhaiya

Thanks rahul....

@Arun sir: Sir, thats pure serenity. Sir, which control board are you using ? Any suggestions for hovering ? And sir as i mentioned earlier, on one flight the quad crashed and i saw one lead was open, the esc was burnt again in arm one. Any idea about the defect

Abhishek cal me arun
And I am using the kk2 with v1.2 and some pid tuning...
Now hoverng is all depends upon the stability of the quad, As in my reptile i need to do more cg adjustments but yours is a cross frame and no need of that... Make sure there are no vibrations and the quad is placed parallel to the ground.
Now increase the throttle and slowly and trim untill the drifting is minimum...
Now lift up the quad and try to keep it hover in a spot by using all the three controls simultaneousl, You will succeed..
And about the esc, You sure This motor can handle a 8" prop and keep the A below 20? as it is 1800kv?
I doubt that

@Arun : I recently upgraded to 30 A esc and the props were adopted as per the results of the online calculator. I will incorporate the kk2 board.. and try to adjust the trims..

Never worry about the board.. KK2 is a good fc but still All others can also do the job just fine...
you just need to build it properly... An unbalanced prop will make massive drifts...
30A is just fine i think..

Abhishek your motor can use only 7x3 prop with 3s...
See the attached file... And using more than that may burn it...

@Arun Sir: Thank you again Thanks a lot.

Nice build.PID values seems to be the only culprit.

@The Hobbyshop: Thank you for the compliment. I will do good to stabilize it.

Hello everyone,
Since this quad build, I have been meaning to build one more, with a custom frame and if possible include altitude hold and provide hovering capability. I have a few spare esc's with me. 20 amp. Which motors do you all think will be suitable for giving thrust sufficient  to lift a GoPro and may be a 5000 mah lipo. Thanks in advance.

I think 1000kv 2836 will work okay.
or you can use 2212 920kv

Using 20A with 2836 is risky... it is rated Max amp as 18 but still 30A is the safe range for a 300+ w motor...
And as you are planning for a go pro also...
Still sticking with 20A then need to go for lower kv motors with 15A Max current or so..
May need to use 4s lipo...

Good to know that your quad now gets up in the air, Abhishek.
I suggest you use some foam/thermocole to protect the lipo as well as to serve as a good landing gear.
