Installed the firewall and motor/prop. Sounds really awesome when turned on. This is the 1450kv motor they recommend on the flitetest.com build. 7/4 prop. One problem i did have was that my 2200mah battery was a little too tall. I had to cut a hole in the top door to make it work. I decided to build a little cage around the battery so it could not move around in flight. This is reinforced on the bottom with 4 Popsicle sticks. The CG on this thing is premarked by the flitetest team so i know where to balance. Issue now is figuring out how much weight i need to put in the nose. Even with a gopro it is going to need a bunch more weight to be slightly nose heavy.
