Hi All,
I am starting this thread for a "UAV" .
Fahad wants to build one as a project, please can the experts out there give suggestions..... Thanks... Deepak
Hi every one
This will give u enough insight of what we plan to do but we want more flight time so we can cover more area,
for indian farmers it will be a super cheap if its made in india.
We are trying to build a glider which can carry a camera with PTZ setup of 1kg, the reason of glider is it can carry this for the longest amount of time, As compared to a quad and powered model .
Once the model is ready in flying condition we intend to make it autonomous Robosoft Systems which is a registered company in India under companies acts 1956 is partnering with an institute and plan to make it commercial over the yrs .we have strong background in robotics, embedded systems and have done various projects for different clients.
We lack domain experience in aero modeling and are looking for advice from experts like you over the subject.
For more information and authenticity of our back ground you can Google about me and Robosoft systems.

This is Fahad,
"Dont you think a petrol engine will be better suited for this. Can you imagine the number of batteries and cells required to fly for 3 hours?"
we had given a thought over it and concluded electric would be clean n simple which will have no issue of engine cuts ,vibrations, noise which comes with ic engine.
Also the payload you want to carry is 1 KG so why does the plane have to weigh 10 KG??
no it need not be 10kg if payload is 1kg, it was a ballpark figure I used for finding the kind of setup which will e needed.i was searching on the net parallel to this query and learned that all up wt would be not more than 5 to 6kg.
we plan to use fiber glass which is a heavy material and just did a basic surface area calculation and arrived at 8.9kg , I rounded of to 10kg to be on the safe side.
I am not an expert but you do need to talk to the experts;
Rishi, Sai, Ismail, Vivek, Manjeev and eshwar
Comments from Rishi (Aurora ...Calcutta); Hi Baggu.
........... 15kg ALW in 7ft wingspan. a glider that size , just the glider made of wood, styrafoam, corrugated plastic, whatever will weigh 1.5 kgs
Am I missing a decimal ? or is he carrying BRICKS.
Wing Chord of 6 to 7" Wont carry more than 2 kg even after beefin up with carbon fibre rods.
He should consider this project next year after visiting some sunday flyouts. Build the plane first then we will worry about the motor and battery. Ive yet to see an electric 15kgs in weight. He wl need a double Hacker with gearbox to lift that weight. Price 50000 only for the Hacker ! Cheers,
Rishi
Hi rishi
Yes you are right I got the number all wrong, what we want to make a electric glider which can carry 1kg of payload for 3 hours. So I was wondering what kind of electric set would be required for it
In one place its mentioned 10kg all up weight. and way below its mentioned 1 kg payload !
Okay 15 is out.........................10kg is also impossible too on 7ft wingspan. its fine if he wants a powered glider, but in 7ft he can lift 2 kg max max. That too without a 2G turn otherwise Namaste to the wings.
And if its 1kg payload in a glider then Empty Glider, no engine, wl weigh 3kgs max ! so why are you looking at 10kgs.

Naughty naughty !
BTW, IIT kharagpurs aerospace dept is 4 yrs ahead. Drop the project if its on a national interest scheme. Your own hobby club fine as you have the greenbacks. IIT have made evrything which you intend to do. Even a 12 footer SOLAR POWERED electric glider which has flown continuously for 8 hrs many times. Theyre going for 24hrs soon. All panels imported from uSA cost 5 lacs.....ultra lite. Special efficisnt motors to work on solar energy direct etc etc.( Boeing Project and subsidies). and ofcourse Pilot from Indias Hobby Centre Kolkata.
I
I will be happy if you can pass me the info so I can get in touch with them or their website
That would be great help
Hobby club..................plenty of stuff around. Stick closest toy uor city. I can help you out if i know where your based. I have friends in evry city. Mode 1 and 2.
