Hey Everyone! After all this time I'm finally jumping in and building a 38mm MD. For a while there, It seemed like everyone was building one of these and being the self proclaimed hipster/oblivious person I am I've decided to start one after that hype has dropped off some. So without further adieu here is my design for a 38mm MD. I've had this design bouncing around in my hard drive for at least a year now and I'm finally getting close to building it. Before I started though I wanted to run it by you guys first. Nothing super special but I'm exited to start building it!
Airframe: I'm planning to use the cardboard-composite method that I've used quite a bit and found to be very reliable. This time my plan is to make the tube out of a 38mm motor mount tube with two wraps of carbon fiber.
Fins: These will be made from 1/16" Carbon fiber plate. I'll be making these from scratch as well. I used the same thickness on my recent 29mm MD and I believe the same thickness should work. This is an area where my skill is quite limited so any help is greatly appreciated.
E-bay and Recovery: Due to the airframe being carbon fiber I'll be putting the electronics in the nose cone. For tracking and dual-deploy I'll be using my telemetrum flight computer with a cable cutter for drogue and main. One thing's for sure, I'll have much more space to "stretch out" so to speak in this E-bay than in my 29mm MD.
Motor Retention: friction fit
Planned Motors: The rocket is designed around Loki's 38/1200 case, so it'll be able to launch on pretty much anything.
Predicted Altitude: My current design is simmed to reach an altitude of around 12700 feet with the Loki 38mm K

So what do you guys think? Questions? Comments? Concerns?
P.S. Oh! And a name! I'm about the worst you can get when it comes to naming rockets. If you need proof, go look at the first few posts on my "Querty" thread.
