Thanks to Frank Claunch (the mole), here are the instructions, templates and decals for the Sunward Aerospace Sukhoi SU-47.

Maybe if we ask nice Jack Hydrazine would design an STL file for a 3D Nose Cone with the canopy. PLEASE.

The original tube I believe was a BT-56 tube in the kit. Those tubes are hard to come by now so if one was to do a 3D STL file for this nose cone it would be good to do it so it would fit a BT-55 tube.

Question

Can a ST-13 tube be used in place of a BT-56 tube?

Yes, pretty sure they are the same tube.

My thinking is you can get BT-55 tubes from a few places but there are not that many places to get ST-13 tubes. Centering rings for engine mounts would be easier to get also. Just thinking about someone who would want to clone this rocket. This could be a parts ben clone with standard leftover parts that is if we had a nosecone.

I believe once the original .stl file is created it can be fairly easy to re-size it up or down. Jack may be able to offer both the original BT-56 size and a BT-55 size.

That would be great. One would have the best of both worlds cloning any or all of the Sunward jets.
