I built this one yesterday and flew it this morning with an MMX engine.
Vertical flight and simple nose blow recovery
It's one of Greg Poehlein's downscales:

Scroll down to post #47 for Der Red Max.
I built his carded Cherokee D and thought I'd give the Red Max a try.
If you haven't tried Greg's carded downscales:
Instead of rolling your own tubes, you print out the PDF and roll the "skin" around a BT-5. They feel much sturdier than the rolled tube 110 lb. cardstock models.
Follow his advice and print out the wrap around skin on 35 lb. paper (or lighter weight paper) for the best fit. This time the body tube layer was printed on 24 lb. paper and the seam match was perfect.
I prefer printing the fins on 110 lb. cardstock and did a three layer ply. The inside layer was cereal box cardboard.
The nose cone was a plastic Estes Quark style.
The downscale is only 5 1/4" tall. In the picture, it's next to my full size Red Max - the first rocket I built when I got back into the hobby.
Thanks Greg for all the work you did on the downscales!
