Requests?

For personal reasons, I won't be bending metal or testing much over the next couple of months.   I will however have time to deskwork like posting to the blog.  I was wondering if anyone had any requests.  Design? Drawings?  Analyses?  Data? 

The video from this previous post was taken during testing of a bi-propellant engine I've been working on.   I've been testing various chamber lengths trying to get good combustion.  Here's a picture from a later test.  You can see the Swissflow flow meter bottom left.
