I do have a better video of its final moments with us, but I can't post it here as it would divulge the identity of the client.

How about you blur the client's face?

His face is not important, it is the rest of him that is distinctive. No go figure that out!

Blur the whole person out.

What was the maximum run time you got sir..?? What batteries did you use?? What is the material you used for the frame??

on the other hand you are saying you are human

I am a human who wants to see more footage of the hovercraft.I don't mind blurring people in videos.

Anam, Using a 1800mAh 3S Lipo for the Thrusters and a 2200mAh 3S Lipo for the Lifters. Getting a run time of 7 mins comfortably. Remember, each battery is powering 2 motors ( for lift and for thrust).

Construction is primarily Coro (reinforced with steel rods) and Styrofoam.

Cheers!

Gandhar, I am sorry I cannot discuss this point any further. I too am upset at not being able to post the final video. But I made a promise to the client and I will honour it.

No problems sir.Appreciate you keeping your promise to the man.

Thanks. The promise was made to an Organisation. An Organisation for which I have the highest respect.

Abhay, I just read your post. Yes, every morning I would get up and clean and dust her and check if anything was broken or damaged by my maid during her sweeping. There is a huge emptiness in my drawing / living room tonight. The emptiness also extends to my heart. She was a sight to behold, first thing in the morning. I do miss her now. Anyway, she has gone to a good home where she will be looked after well.

Its a sad moment..
"Even if a wild animal lives around a person for few days, a lovely bond and understanding automatically creates between two", She was VC sir's own creation,... i might have become a part of life..
Its really touching.. jst now i read the thread and came to know that its gone..

hi VC
that was surely a labour of love   
it must be hard to  put so much into a project when you know the end product will not be staying with you.
it looks superb and I am sure your customer should be well happy with it,
pity about the final video........maybe you will be able to see it being operated sometime.
regards
don

these are mind blowing work is these the real?

Hello VC sir...its my first day on this forum and i am glad to see your work.
Coincidentally ,i am working to make a surveillance hovercraft for my final year project(B.tech ,final year,Electronics and Communication branch).
I am running out of time and i REALLY NEED UR HELP...PROMPT HELP I should say.
PLEASE GIVE ME A CALL at 8882324282.
or leave me a mail at "" or give me your number via sms.
I SERIOUSLY NEED AN EXPERT ADVICE>>>
I have only a week left for submission of our project,,,,PLEASE PLEASE GIVE ME A CALL OR TEXT OR MAIL...
regards,
Saurabh Srivastava

Inspired by VC sir, I made a similar project for a group of final-year friends (ETC branch). Check it out, it might help:

And, don't worry, a week is enough time. I made it in two days!

Saurabh will get in touch soon. All the best!

sir, i would like to know if u cud assist me on this-
1.can a brushless dc motor be controlled(only on off mechanism required) WITHOUT using an ESC by any means ?
2.If an ESC is must to drive a BLDC motor then ,can we use 555 timer IC to generate pulse sequence which will be fed to the motor so as to turn it ON and OFF(needless to mention that we want to run the motor at a fixed(maximum) speed/RPM )...?
3.Can cellphone batteries(1300,950 and 1350 mAh respectively) be used to power the BLDC motor and ESC.
4.We are making our own RF based Tx Rx circuitry....will this work properly with the BLDC motor and ESC assembly?
Response awaited.:-)

A BLDC cannot be run without an appropriate ESC. I've studied both and can tell you that a 555 certainly can't be used.
Answers to 3 & 4 depend on which bldc and rf modules you have.

You are one of the rare person I have ever seen in this hobby, Who can put in so much love and passion in their builds while making such a beautiful craft for not even yourself, doesn't need any explanation that you particularly love "building" or in other word, "Crafting".

Real Scratchbuilder you are, VC sir.



I would never leave a chance to see you scratch building. Its kind of visiting Adrian Smith while he designs Burj Khalifa.

I thank God, we have you for our inspiration.

The Hovercraft is really brilliant.

I don't have a third of your electrical / electromechanical knowledge / acumen. I just follow the simple maxim - "If it feels right, its gotta be right!"

 

s I may have mentioned earlier, these three models - the Griffon 2000, Griffon 8100 TD and the LCAC - were made by us (Greatguns and VC) for a 'Client'. The clients identity has never been disclosed till date. I have now decided to come up and be bold about it. Here, have a look at the client's representatives who took delivery of the LCAC.

The person who is in civilian clothes is Greatguns.

Just went through the thread. This must be one of the best scratch built hovercrafts I've come across till date.

On behalf of Greatguns and myself - THANK YOU!
