I few of us may have noticed a post in Yard Sale section titled <Ukrainian R-360 Neptune 3D Printed Parts (Limited Run)> about a year ago, right after that missile had sunk Russian cruiser Moskva.
I ordered the 3D parts, must have received them soon after, but did not get around to building the kit until now.
Since then, one of our own, <BigMacDaddy>, had expanded his line of 3D printed scale and semi-scale offerings into a full fledged RadicalRocketry business with a portofolio of 9 rockets listed on the web site, and a few more on FB:
https://radicalrocketry.com/shop/https://www.facebook.com/Radical.Rocketry
I finally came around to building this kit, so lets see how that goes.
I've built kits with occasional 3D printed components (usually nose cones or some embellishments), but this is the first time where ALL of the key parts are 3D printed from ABS plastic. That may, or may not, require extra sanding and priming. We shall see.
For starters, here is what you get to work with, and the end result we are aiming for:
I ordered the kit with the optional precut 3-ply plywood fins, so that took care of sourcing material for the three (3) sets of fins that go into the kit.
In addition to that, the build calls for self-sourcing of the following tubes:
Otherwise, one can get all those tubes on the cheap from eRockets.

In addition to that, the build calls for self-sourcing of the following tubes:
- BT-60 (42mm OD) Sustainer (2nd stage) airframe: 336mm
- BT-80 (66mm OD) Booster (1st stage) airframe: 52.5mm
- BT-50 (24mm ID) Booster Motor Mount Tube: 80mm. I doubled the MMT tube requirement by adding another 80mm MMT for the 2nd stage (original build calls for a MMT only in the 1st stage, and using ABS centering rings to secure the 2nd stage motor w/o a MMT).
Otherwise, one can get all those tubes on the cheap from eRockets.
