Flying Model Rocket ESA Maxima with shuttle

This is my next rocket that I designed...I made two versions of this, one much large than the other. This is the SMALL one which can be printed on smaller printers. It is winter here, so I have not launched either rocket so if you launch it before me, give me some feedback.

Based off of the ESA Maxima rocket. The Lander is designed to glide down on its own with the bottom half coming down by chute....but I will see how it works when I launch it. I already know a couple modifications that I may have to make...right now I anticipate the lander will come down more like a dart. This was made off of some prototype pictures that I had found of rocket designs...

I use Polypropylene for my rockets, it is about 1/2 to 1/3rd the weight of PETG...I love it. This one is designed to fit a "D" size Estes engine in it. I'll post the larger one also which is designed for a "E" type engine. You just slide the engine in and screw in the tailcap to hold it in place.
