Title: Quad- DHRUV Post by: RcBharat on April 23, 2013, 08:19:35 PM Hello folks,
It has been very long since I posted something very interesting. Working very busy these on some projects mainly multi rotors. Was actually very lucky to work on some huge ones too. This quad DHRUV was also made for one of my clients for aerial photography with an SLR camera. Couldn't find enough time to click pictures while building it but I have got permission from my client to share its design and build details if anyone finds it interesting. It's a 40 inch quad with AUW almost 4kgs A few more details: Motor to Motor : 40inches Frame Composition: Aluminium and fiber glass Motors: 730Kv http://www.rcbharat.com/brushless-motors/190-a3250-6-730kv-brushless-motor.html ESC : cloud 80Amps ESC http://www.rcbharat.com/escubecvr/206-mystery-pentium-80a-brushless-esc-w-o-bec.html Battery: 2500mah 4cell 40C liposx2 Props: 12x4.5 SF Controller: DJI Naza with GPS Flight time recorded: 18min Test Flight 01 http://www.youtube.com/watch?v=RzSp5qxD2Q0 Test Flight 02 http://www.youtube.com/watch?v=t7nL0hRYOOc&feature=youtu.be Sai Krishna 9989120724 www.rcbharat.com Title: Quad- DHRUV Post by: RcBharat on April 23, 2013, 08:50:15 PM 2nd video link fixed :thumbsup:

This isn't my first project with Naza. Already finished a dozen. Go for gps, it's cool. I always prefer flying in place which aren't much crowded when using gps and use a proper tx with two 3 position switches.

You can trust DJI. Good luck. Sphere Hobbies DJI Distributor, India +91-99251-20630 Title: Re: Re: Quad- DHRUV Post by: RcBharat on April 24, 2013, 08:24:38 AM Yes.
I always feel that failsafe is something which should be used when you really feel you cannot get the machine back. I always setup failsale by turning the tranamitter off.

Do you have more details on payload capacity of the craft?

Anyways could you please let us know what is the reason for asking? If you need one please write to us at rcbharat@gmail.com, can pass you the complete details.

Please let me know if you guys are the official distributors/dealers for dji in India, as I searched for dji indian delears couple of months back to buy a few naza's and couldn't find any official distributor in India on dji website.

Yes, we are officially dealer for DJI in India (if you write DJI, they would confirm). Per DJI policy, it would take some time before they publish Sphere Hobbies on their web site as dealer/distributor. However, they always transfer us all the queries of Southeast Asia.

Wishing you good luck. THANKS Sai Krishna 9989120724 Www.rcbharat.com Title: Re: Quad- DHRUV Post by: Rahulvyas on April 24, 2013, 08:10:55 PM Cool build.
What material did you use to build the landing skids? I suppose its a kind of plastic? Is it good enough for hard landings? I am building a hex and need help with building the landing gear. Title: Re: Quad- DHRUV Post by: Rahulvyas on April 24, 2013, 08:13:57 PM if you land hard, your aluminium booms will bend. I think its dangerous. Why did you choose this type of landing skid?
Title: Re: Re: Quad- DHRUV Post by: RcBharat on April 24, 2013, 08:32:50 PM Rahul
The landing gear is made out of 4mm fiber glass. Which is hard enough if the quad falls from 15-20 feet also. Anyways I don't land hard, so no worry of aluminium bending/breaking.;D Sent from my GT-N7100 using Tapatalk 2 Title: Re: Quad- DHRUV Post by: Rahulvyas on April 24, 2013, 08:40:01 PM haha cool.
What is the center plate made from? Title: Re: Re: Quad- DHRUV Post by: RcBharat on April 24, 2013, 08:41:57 PM There are 3 center plates all made from 2mm fiber glass, laser cut.
