Falcon 9 model rocket add on's

Project Update 8/3/16:
I am currently focusing on the design of the MHE (mini hybrid engine) I will return to the other design work after the final engine configuration is determined.
All the engine tests can be found here http://atgdynamics.blogspot.com/ and my youtube channel https://www.youtube.com/channel/UCo6xj2n2NLAi2J3u42D0g6w
