I posted about this elsewhere but wanted to get some feedback on the design before I print larger.
Thanks to @lakeroadster for posting the video that made me aware of this tank round. Cool looking model that was not too complex (and seemed aerodynamic rocketry-wise). My first version is made w/ a BT-80 + BT-50 tubes + 3D printed parts + plywood fins (my MO). Should be launchable on C5-3 or D12-5 engines and I guess I will load an 18" or 24" chute in there (could also use an E12-6 but I setup the motor mount for shorter engines).
I am planning to make a 1:1 scale version with a 4C ice tea canister so wanted to get feedback before doing so (will be 129mm so bit larger than 1:1).
Here is my 1.0 design and 1.1 build as well as latest design (just fins have changed I think). Last picture also shows the 4C canister version vs. the BT-80 version::
Thanks in advance for any feedback!!!

- What do you guys think of the design? Any changes / improvements / suggestions? I did modify the fins for a new version (the flight part of the video seems to show more streamlined fins than the static close-up picture I grabbed from the video).
- Do you think I need a launch lug near the rear / fins? I currently just have the rail-lug in the middle.
- Any thoughts on mechanism to make fins open automatically if someone was doing a tube launch?
