Hi. Ive been building quadcopters for a few monthS now. I have always used aluminium for the arms and plywood for the centerplates. Ive modified some off the shelf sponge toys to use as landing gear.

Veteran Quad builders seem to be using quite a lot of other materials, from carbon fibre to glass epoxy etc.

Has anyone built quads (arms, center plates, landing gear) with other materials (non aluminium and plywood) sourced from within India? Where were they bought from? How did they perform in crashes?

Good question. I would like to know too. Btw subhash bro do you have videos of your quad? It would be great if you share your knowledge with us.

Hi Dharmik, I am new to RC. Used to fly cessna's and then some paragliding. Just looking to get to FPV as a means to get back into the sky. Not sure anyone cam learn much from my build notes.

I built the first one (posthumously named the "Titanic") and lost it when it flew out of radio range. It was built with 1 inch aluminium U section for arms (8 inch long) and anchored with 3bolts to a single center plate 8 inch dia and made of 6mm plywood. 2822 motors, 8inch props, turnigy ss18 esc. Hk 2.1 control board. Found it easier to fly it than to hover it. Had to crash land it every time 

The second one "Queen Mary" has been built (with a Naza FC) and am building a third with provision for FPV. This time built with square aluminium sections and 6mm plywood sandwiching the arms. Using DT700 from HK and turnigy plush 25A.

Its a bit windy here in Bangalore and am waiting for "ideal" conditions to fly "Queen Mary". Will post pictures IF and when I can get it to hover.

I just built one with coro (I call it the corrocopter).

Being new to quads and helis in general, finding it a bit difficult to get it to hover

What is coro? Is it a dense plastic like material?

Its sign board material and is the core ingredient used for cooking SPAD (Simple Plastic Aircraft Design) planes

If I remember correctly, we're already introduced at DFI... welcome to RCI, btw.
