HED

Basically DD with no payload tube, right? Main is in NC, drogue in booster, NC coupler is the AV bay. Am I understanding that correctly?

Was thinking about getting a Formula 75 to stand up next to my Formula 200. Newer ones from Madcow are HED. Would be fun.

You are correct.
Just building a Wildman 98mm Interceptor AAD now that is also HED. I think I will complete as HED but separate for the drogue at the body midpoint. I haven't seen a HED rocket fly and I'm a little concerned about the whole body being one piece and separated at the Avbay which is essentially the nose cone. That is a lot of rocket to come down together! I have read that a 9-12" drogue will keep the whole body from orientating so as to become ballistic and maybe so, I'm just not comfortable with that yet.
I will be attaching the upper body to the avbay with flathead screws and the tube will be shear pinned at the body midpoint coupler. So in the future I will be able to configure it as it was originally was designed to be flown as HED

I guess you didn't see my Formula 75 fly Sunday, HED with an Top Flight 18" X-Form drogue and a 54" Spherachute main. Three 2-56 shear pins hold the nose on.
