Contact me through inbox or PM

@taksh,
Which motor and Esc?
Please post a picture of the glider.
And a short video of how it flies without RC and motor.
What’s the weight of the bare glider?
What’s the weight of the proposed motor, prop, Esc, Lipo and Rx?

I can send you a small 1s lipo for Rs 5000!
If you answer the above questions and post a pic, price reduced to 500.
If you post a video, price reduced 100!

Actually free, once I find where it is. Just 500 for Blue Dart!

Other members please don’t get irritated, Taksh is a personal friend (though we’ve never met), ok?

48cm hand thrown glider from Aliexpress.

I have a coreless motor with propeller.
And wltoys F959 PCB board with inbuilt two mini servo.
And I have ordered a lipo but item will take time to reach its destination because it's international.
I can't wait for a month or more.

Though the foam is claimed will not broke, but I found one wing broken into two pieces, just for Discus launching.
Trimming foam with hand bending generates crack of joining bubbles.
It is sold on Amazon.in for Rs. 75/- and in road for less than Rs. 50/- (feedback from Amazon).
They use iron ball for weight, and trimming need sharp razor blade, as different foam side edge not proper. In one of my 5, I got one ball missing in one. The canopy sits only using press fitting, no magnet.

For LiPO, you need charging circuit as well as protection circuit against deep discharge. The circuit will give additional weight.
Better use Supercapacitor. 6 nos 10F Supercapacitor of 2.7 Volt are sold for Rs. 500/- including postage.

If you still want to use lithium battery, go to nearest cellphone repair shop. Ask them for Bluetooth lithium battery. And for motor, use 6x16 /7x16 motor with 55mm prop.

I did RC conversion to such chuck model for one of my friend.

Some pictures to give you some ideas Taksh.

Do not have a flying video. .

Thanks for KALYANPRODHAN and rastsaurabh for the information.
I have Wltoys pcb board with inbuilt two servo, receiver and with coreless motor  output

This may help with the video of flight.
