Hello everyone,   

I have built a micro quad. My primary intention was to make the quad flyable indoors. While searching for the frames, I found that the frames available online are mostly heavier than 40g, since the primary intention was to keep the weight minimum, hence I made the frame myself.
I used carbon fiber rods for the frame, and used Avionic 3500kv motors. These motors are primarily made for small planes (They come with prop savers, one can not fix a prop adapter on these). But since I didn't have a lot of options for a cheap micro motor, I went for these.
Here are the materials of the frame, I have fixed four carbon fiber rods by araldite, and used zip ties to strengthen them. Previously, I made a similar model without using zipties, but this time those tiny ties have made the frame rock solid.

Note: I used Bengali Newspaper, it shouldn't be a problem, and many people from West Bengal visit this forum regularly.

One thing to mention here (Can't resist myself marvel at micro motors) I also bought DYS 4000kv motors sometimes back. Oh Man, you'll be amazed by the size of this one. I have taken some pictures. the DYS motors are only 5g compared to the 10g Avionics. Look at the size.  But the DYS motors get quite warm, I don't know if that is a problem with such a high kv motor.

I am using the SimonK 12A ESC's with avionic 3500kv motors for the quad.

OK, then I soldered all the motors and ESC's together. I reversed two wires of two motor-esc combination. I didn't use any PDB, I soldered all the ESC wires together to a JST connector to connect to my battery.

Fixing the motor and electronics to the frame. The props were set only for reference of the size..

testing the motor orientation...

I made the baseplate using a small PCB, and used some rubber vibration isolators I got from DVD drives to fix the Flight controller onto the baseplate using hot glue.

fixed the FC and the RCB 6i receiver to the base plate. I have a small Rz4 receiver, but am saving that for a small micro (perhaps) plane that I am going to build. I thought of making the quad FPV supported, so tried to fix small Tx and camera on it too. But I think I will first sharpen my skills without the FPV. then I might make another frame suitable for that.

Well, the video is taken without the fpv gear on it. I must say the motors are fine, as they come down only a little warm. But I had problems with the prop savers. Using the normal prop saver bands, the props were flyign ayaw and there was also heavy vibration. But I have used regular rubber bands to tighten the props to the motors, and since then, no problem. I have used Turnigy 1000mAh 3S battery. With a 2S, it becomes quite underpowered. 3S is the most suitable battery for this.

What I have learnt is that you can not make a true indoor quad without prop guards.

Superb sir

Nicely built sir...... .

thanks Aruz and Pranav.

Hey! Nice build man. Will you be putting the action cam on the quad

I am not going to put an Action Camera on the quadcopter. I will put a light weight FPV camera on the quad, right now preparing for that.

In home Nice indoor flying.. Sir..
