Thanks..

6 amps per motor or by the entire drive of 4 motors??

Per motor ayush; not all ....entire drive is about just above 20 amp

thankyou for clearing the doubt 
really ,could you please share a link for that motor it would be great ,

I'd like to get those motors for my quad too.

Hey nice work hemanth bro. I found that just bit more throttle above hover position gives allmost double flight time so 36 minutes is possible. There is record on rcg '51 min in air' without payload you can achieve that and as you said overall current draw is 20Amp then you can push the limits. Keep it up.

Here is the link of the motor:

But please get ready to punch your pockets for those

Please read the specs of the motors; Then all the doubts about the fly time will be clarified.....

Woah! Amazing specs! Just went through the tech data.
Price is a pocket burner, though...

 

My new AD8 Heavy Lift clone ; 60% the cost but 96% carbon fiber






Motor mount




Belly of the beast


Center plate 5mm 3quill carbon fiber



Call me for pricing....

First of all congrats on your achievement ... your achievement is so great that its hard to believe.

 

I did some calculations and seems something is wrong …

Time = Battery capacity / Current drawn

Battery capacity (Ah) = Current drawn (I) x Time (H)
so, 2.7 = 2.7 * 1

It is said that given system needs 20 amps

Time = Battery capacity / Current drawn

Time = 2.7 / 20

Time = 0.135 (H)  = 8 minutes

this is considering that it will take 11.1 V all the time

Now If we consider it only take 5.5 V then also flight time will be about 16 minutes

Can Hemanth/anyone please explain where my calculation are wrong?

Sir for which MR did u do the calculation Quad or my new octa

Saw the motor link thanks for that..

Btw what are the lights that you have used. And where did you buy that frame from??

Exactly my view, he says 6 amp avg current draw ie 24amps for 4 motors. Not 20 amp like you calculated.
I have various quads and various motors including the said T motor, mine with a 1045 prop draws 9 amps at 75% throttle.

The lights are from HK and the frame custom made out carbon fiber

I will post the calculation please give some time,,,,,

Check the reply by Hemanth Reply #27 and that is why i consider 20 ...

We all are eagerly waiting to know the math behind this..

and if it works as you are saying then ... we can upgrade easystar with this motor and fly it for 2+ hours

Hemath, Please dont call me sir... I am not senior in this hobby.

I did it for your Quad  as you said in reply # 27 that it draw 20 amps and the link which you gave says motor will take avg 6 amps and battery capacity is given as 2650 (rounded to 2.7A)

Oct finally files



I tested it with WK-M

I will test with my INS system soon;

The gains need to be tuned its just first flight

sir what is the brand of your six sensor quadrotor contol board and what is the cost
please post the link for control board

@hemanthguru:
I wonder how I missed this thread.

1) You say the FC is 32-bit. Which CPU is used? STM32?
2) Is the code self-written?
3) Any GUI for configuring various parameters or do you just use those on-board pots?
4) Can you specify the IMU used or the names of the individual sensors?
5) Did you port any open-source multirotor platform like Multiwii onto your code, or is it completely different?
6) Do you plan to retail it? If yes, at what price?
7) Is your product open-source? Can anyone modify the code to their interest/requirement?

And I must say "GREAT JOB!" I am EXTREMELY proud to see this from INDIA.
