I just had a good look at your web site, very interesting idea, I would be worried the ship would be blown away. How often do you find it too windy to fly ?

I want to your website and I am very impressed. Did I see the motors reverse?

There must also be a best balance point. Where it that?

Also: the balloonkits.com seems to only show metalized Mylar. Did you get your Mylar there? If so, what thickness is it?

Seriously... I showed your site to my wife. She instantly wanted me to build one, so expect a flood of questions!

Thanks...

Motors are not yet reversing but they will be.

One motor is turning left, one is turning right (it is contra-rotation) for a zero torque.

The best balance point is from 30 to 48% from the nose (depending of the size of the fins).

The best film for this size of blimp would be 30 microns.

I will make a test with balloonkits.com's Mylar.

I would like to find Polyurethane film, but it is very hard.

Heptax can be used.

I think it is not stretchy enough.

I would prefer polyurethane.

By the way, I am looking for 30 micron polyurethane!

Do you really mean polyurethane or do you mean polyethylene like the clear bags that everything comes in these days?

Polyethylene is good for testing but is not good for helium.

Polyurethane is Helium proof.

I will soon have a big roll of it (2/3 months) (140 kg)

I will then manage to resale small quantities by meter or by Kg.

I might be interested in buying some. From your videos it looks like shipping might be expensive. Please keep my in mind!
