Looks like its time to start the blog, going to post setups to start then add as things come up. I also want to greet the community officially and thank everyone for all the great ideas and help that have inspired and made these builds possible.

I got this on from Ebay when they first became available and was originally running this on 3s 2200mah 45c, 930kv 2212 Rctimer motors, 9x4.5 inch props, 30a Rctimer escs, Multiwii 2.2, 1100 grams.
