Received mine from Hobbylinc yesterday, This thing is massive! I Already own the Executioner, and Leviathan (Both built to instructions) but this thing being the first 4" rocket Ive ever owned is Huge! I have already started to amass the parts to build it. I, like alot of people will be using rail buttons and an Aeropack retainer, and looking into a baffle system.
Was wondering, for stability, I've been reading to set the baffles farther forward, or build it into the coupler. The MDRM not having a coupler, whats the best way to figure out the placement of the baffle? Or do I incorprate it into the MMT? I still have to buy a scale to check the weight. I am also undecided wether I want to upgrade to 38mm or stick with the 29mm.

Oh and I also received the MiniDRM, so now have the whole family as I had already built the DRM! Cant wait to see them all assembled together!

I don't know if it would work for you, but I usually put half moon baffles in the motor tube, and build the rocket with a zipperless design.

That looks easy and economical, Still gathering parts and placing another order with Apogee, going to draw up a few options and see what I come up with.
Thanks Quake, Awesome builds by the way!

I am also finishing a custom MDRM! I have reversed the color scheme to make "der HARLEY MAX" ! Sandman is making my custom decals and the proofs ROCK! Here is pic of masked paint before clear coat. Motor mount is "bored and stroked" from 29mm X 8inches to 38mm X 12 inches... MWWWHAHAHAHA! LOKI 38X120 ready and 38 X 240 bought in anticipation of LVL 1 attempt! =)
