This is my scratch built rigger built out of 2mm ply and .5mm carbon fibre sheet. I think i'll call it the scorpion because it kinda looks like one. I don't know if it works yet, and whether my calculations for the angles and distances were ok....but i did check to see that it floats and doesn't leak. Hardware is home-made (rudder needs to be changed because i tried to clean it with acetone, and this melted the plastic.

I might need to take the strut up a little - we'll see about that after the first run.

It's powered by a 3000kv outrunner that i took out of my iceberg (she deserves better i think) and a 2s lipo pack. All up weight is 410 grams.

Here are the pics:
