OK, I will ask. What is the purpose?

do you have any pictures of the premix tank? Thanks!!

It hasn't been prototyped yet, but he's drawing it up in CAD and should be able to post some pics of the math pretty soon.

This is by far the best solution I've seen yet, and was dreading the thought of finding a good spot to mount one of the off-the-shelf tanks.

I'm sure if this was posted on some of the other forums, there would be a lot more interest. This site doesn't seem to have the traffic----yet.

When you get a real prototype i would recommend bringing it up to howard coleman. He will likely purchase one and people have a strong tendency to follow his lead. I hear he is going to possibly be running a rotary aviation adapter some time in the future. I am totally interested.

See GB for Protoype CAD views.
