Hi William,

You can get a tubesat both with or without electronics/radio. I think  
you can even use your own structure as long as it fits into the  
envelope specs.

Max OD = 8.94 cm (3.52 in), ID= 8.56 cm (3.37 in), Length = 12.7 cm (5.0 in)
So it is slightly smaller than a cubesat in one dimension, but longer  
in length.
You can get the full specs on their website:

There is a PDF/word file

Indeed!


> Anyone already have experience with these tube-sats ?

I do not have any practical experience with them, but I know they have  
been working on their launcher for many years. If I had 8000$ I would  
buy a tubesat.
Of course, since their launcher does not have any track record, it  
should be considered as high risk. But who cares? I mean if you  
compare it to the price of a cubesat launch today, which is how much?  
80000$?
