Title: Scratchbuilt Quad - Maiden/Test Flight.
Post by: VC on January 06, 2013, 11:58:57 PM
She seems stable, I need more practice and guts (lots of it) to let her rip. Wish me luck.

Camera purchased and tested but not yet installed.

Thanks all for the encouragement.

:thumbsup:
Quality build VC sir!

Veloci, my friend, I will disagree with here. By any means this is NOT a Quality build. In fact, I wanted to prove a point with this rough shod / slap dash construction. I did not go in for any complex calculations nor did I use slide callipers or vernier scales while taking measurements. A simple foot ruler was used.

What I am trying to say is, the construction of a basic Quad is EASY. Some people will tell you that it involves a lot of complexity and calculations - here is proof that even an idiot like me can build and fly a Quad with ease. The KK board with the LCD is all forgiving and takes up a lot of slack.

My advice to all out there (and I probably speak for the Maestro Ashta Sir) Go for it - it's EASY! You just need some good advisors to guide you through the build. I had a solid team backing me up - Ashta Sir, Gusty, Sandy, V.K. Singh, Adiboy and Subhash Reddy. :bow:

A few queries VC Sir
1. Why is that your are launching it from your hands?
I feel its dangerous

2. The tuning seems to be perfect as I'm not able to notice any considerable vibrations.
What is the control board used?

Sai:

1. That is just the way I am. I know it is dangerous and that is why I have posted a warning about it on Youtube. Yet again I do it as I am comfortable with it.

2. The board is the HK KK 2.0 Board with an LCD panel:

Satya: I agree, but then again, every time I hold a fully charged LiPo in my hand, I am asking for trouble............

If it flies well, there's nothing better. Agree now VC sir?   ;D

 :thumbsup: Thank you, Veloci, my friend.

All items procured and ready for the Hexacopter. Much bigger with more powerful motors. Should start work on it soon. In the meanwhile, I will keep practising with this baby.

Better videos to follow, soon, I hope.

Common Sir, You need to be safe today to fly tomorrow again.

Thanks for your concern Sai, howver, I reiterate - that is the way I am. Learnt how to ride a motorcycle when I was 40+, that too on a beast (Yamaha RD 350 HT) that I have grown to treasure and love. Did a Paragliding stint without a helmet at the age of 45. Crashed my Opel Corsa at 150 K.p.h. the same year. Lived through it. What is a small plastic prop going to do to me that hasn't already happened? But then again, that is my philosophy and I don't force others to follow the same. It is my way of life. Living each moment as it comes peppered with a wee bit of danger. I am about to complete my half century in a few years. Let me take my chances while I can. Stop preaching to me, I am not listening.

What is life without a little bit of spontaneity and a dash of insanity? After all, I am the Enfant Terrible. ;)

Perhaps I am setting a bad example to the youngsters reading this........sorry about that. ;D

DON'T TRY THIS TILL YOU ARE 47 YEARS OLD - THEREAFTER IT'S YOUR CALL......................

Very nice ;D
I tried what you did(prior to reading this post) and received a scar that I can cherish for life :P Wasn't even flying, was just checking the frame..
Can you post some close up pics of the frame please? :)

What's a man without a few scars?

If only my mum would agree :P Are those coro tubes triangular with the flutes running along the lengths? A very clean build!


Title: Re: Scratchbuilt Quad - Maiden/Test Flight.
Post by: VC on January 09, 2013, 01:05:30 AM
Nope. The Coro tubes are not triangular (They are not tubes, just flat pieces of Coro) . The main strength comes from the aluminium arms.

Nice Build VC sir,

I would suggest putting both Green props at the bottom or at the top of the X


Title: Re: Scratchbuilt Quad - Maiden/Test Flight.
Post by: VC on January 10, 2013, 12:06:17 AM
I have oriented them as suggested by the LCD display readout of the KK V2 Board. What is the advantage of doing it your way?


Title: Re: Scratchbuilt Quad - Maiden/Test Flight.
Post by: veloci on January 10, 2013, 12:46:51 AM
VC sir, Sry to gate-crash. I think wat he really meant was to use two diff coloured props in the front n the rear. This helps in knowing the xact orientation of the quad in-flite. Right hellyflier?


Title: Re: Scratchbuilt Quad - Maiden/Test Flight.
Post by: VC on January 10, 2013, 01:30:05 AM
That makes sense. Must try it the next time I fly. Thanks Guys!


Title: Re: Scratchbuilt Quad - Maiden/Test Flight.
Post by: Hellyflyer on January 10, 2013, 05:29:23 PM
Yup that's exactly what I meant  :)

Hey Guys, overwhelmed by the fact that a 30 sec video has elicited so much of support and encouragement from all of you. Grateful.

quite stable, and very tentative flying. V2 should be good

'Tentative' is an understatement...................
