http://blacksheepsquadron.com/generic_info.html?gclid=CP_n1LPLo54CFZ1h4wodGTDLmA

have a look and share your knowledge on this

Sandeep

here is the video of same

looks like it works similar to the air car( car running on compressed air) which is being  developed by MDI of France . Incidentally TATA which has a stake in MDI  is developing a similar system for the NANO

The title of the video gives a good hint. Its a compressed air or CO2 motor.

my son had an airhogs model like this. All plastic.
The fuselage had to be pumped up and the motor would run for about 45-50 seconds.
Free flight model.

I don't remember where but I had once seen this video of a liquid nitrogen motor.. They just put like a few drops of liquid nitrogen into it and the motor ran for a really long time.. Cause when liquid nitrogen is brought up to room temp it produces nitrogen gas which is like 600 something times the volume of liquid nitrogen used!!

interesting... reminds me of the old cox teedee and Cub engines...

I don't know about the mechanism inside it, but these CO2 cylinders looks a bit same what we have with Life Preserving Jackets (16 gms) provided by AIRINDIA.   

Doc, the airhogs is a compressed air system, this is CO2 system and very poular with specialist modellors especially in UK, absolutely clean technology too

May be you are right, I found 2 nos of small cylinders (written - 16 gms of CO2 packed) with a Life Preserving Jacket.

Thats similar to the cryogenic engine being tried on the GSLV
