Nearly five months have past since I took up this hobby, and after Sky surfers, Shikras and Flying wings, a multirotor was my next choice.
FPV was on my mind as well, and due to lack of proper flying space, FPV with a Quadcopter seemed logical.
So my research began, and after hours of searching on the forums and countless Youtube videos, I fell in love with the 250 size mini quads. There are many to choose from, but the "Blackout mini" appealed to me the most.
Then I saw the price of just the frame and the proverbial "hawa nikal gayi".
9000/-  + shipping for just the frame.
So my new mission was to make a high end mini Quad on a low end budget.
My first step was to get the frame fabricated, and Quadkopters.com came to my rescue.
I downloaded plans from -http: //untestedprototype.com/  and give full credit to them.
Plans were sent to Quadkopters.com for pricing. I chose carbon fiber for materiel and to my surprise the total cost worked out to below 1600/- delivered to my door.
1mm CF was used for the center plates and 2mm for the arms. The quality of work done by Satya and team was excellent.

Good going ashimda. What power system are you planning to use on this quad?

Next came the electronics. For the best performance T-motors are recommended, particularly the MN1806 2300kv Motor, but they are over 2500/- X 4= 10K for
4 motors. So a little more research led me to some cheap alternatives.
SunnySky X2204S 2300kv are a favorite among the mini quad community, but they are practically impossible to find in stock. Another favorite  are the
RCX 1804 2400kv. The RCX are available and 4 motors work out to 2160/-
All the above motors support 3 cell, so 3 blade props are not required.  

From where did you buy RCX motors?

RCX motors are available at both banggood.com and rcmart.hk.

Superb Build ashimda..the website is a good find...subscribed..suggest you update the first post with links to the parts as well.

Thank you Ankur. Done.

My motors and speed controllers arrived today.   So now the build can commence. The RCX motors come with cw and ccw thread and are good quality and weigh only 16g. The 10A RCX esc weighs in at 12g. I had originally settled for the KK 2.1 board as my first FC, but found the mounting screws did not match the Frame holes. Two holes lined up but the opposite two did not. I had also ordered the Crius MultiWii as a backup, but that too did not match the mounting holes.
For those planning something like this, remember to measure everything.
Fitting the motors required a little filing so the screws line up, not a problem. I decided to fit all the Speed controllers on the dirty plate instead of the arms. More protection that way. I also fitted a power distribution board, but might solder the connections together.

Very good work mate. I am planning to build on same blackout mini h concept.

Thank you Dharmik.

Some more photos and do upload flight video really interested to see it fly high

Another great build very neat

Thank you Roshan and Rahul. Will upload video soon. Could the experienced lot tell me which FC is better for this quad, the KK 2.1 or the Crius MultiWii.

Go with KK2.1. you can tune your quad on the field and there are so many topics available on the internet on various rc forums.

Thanks for the suggestion Darmik. The KK is a little easier to configure as well. 

Yeah for ease of use KK 2.xx, least amount of tuning required in terms of setup. If you want something little more complicated with ability to add sensors later on then Multiwii.

Multiwii boards with exceptions can be equipped with lcd screen to program them on field without any computers and they can also be programmed via radio Tx .They can be hooked up with Bluetooth to change setting wirelessly.And there is an active community for support.

What about auto level, which one has better stability?

Well frankly for a general user, stability and auto level would be the same and you wont find much difference if you have properly tuned PID's on both boards. And tuning multiwii is a task in itself if this is your first attempt with multirotors. I faced a couple of problems with my first multiwii due to PID tuning which I never had attempted in kk 2.0 since defaults usually worked well for me.

I would suggest KK 2.1 or 2.1.5. You can move on to any other FC's later when you are comfortable and you will always have KK to fall back on

Cheers mate.

Finally managed to get my Mini Quad in the air. I broke the limited number of props I had, trying to tune the FC. Props arrived yesterday and took it for a test flight.
My first time flying a Quad, the only rotor experience was the V911.
The AUW w/o battery is 273g.
A few more pics and the test flight.

NIce Quad Ashmid Sir, I really Loved it. Which FCB did u used finally.

Thank you miginstrument, I used the KK 2.1 board.

Welcome Sir. I ve recently built a quad using Rotorbits Frame, its a mix carbon Frame. n I ve used Naza m Lite with GPS. ll post some pics soon Sir.

Looks good

Thank you Satya, major credit to you and your team.
