Re: HPR X Wing - T70

I ended up creating two plates to sit under the droid cockpit to hold captive nuts in place. I original planned for 8 nuts but those closest to the motor tube did not have enough room, so I redesigned it to use 6 instead. https://live.staticflickr.com/65535/49378116298_d5db27f4b7_z.jpg X Wing Droid ...

Re: Modular Rocket

Looks pretty nice. Kind of wish I had added a place to put nuts in the cockpit for my X Wing, but I didn't because I wanted to make sure it never fell out because there will be no access to the underside.

Re: HPR X Wing - T70

It’s a new year and I’ve finally managed to get my butt into gear and learn some CAD and 3D printing... So I started with this CAD model curtesy of Sean Lavallee at https://grabcad.com/library/star-wars-the-force-awakens-bb-8-droid-1 https://live.staticflickr.com/65535/49338705778_f4d93ca723_z.jpg B...

Re: Hoping everyone is safe

That’s why we don’t make our own motors, launch pad distances are critical, motors are not stored assembled and igniter only installed on the pad. Also helps that AP doesn’t easily ignite.

Re: Backup build for Havoc - 38mm MD

My preference is for the clipped delta, the reason is to get enough fin out in the clean air. You want to avoid turbulent airflow that is close to the body. If you make your span to small then I think OR will actually give you a warning as the calculations assume the span is larger than the body tub...

Re: Swirl injector for 4" hybird

Great result. Is it just instability or does this improve efficiency as well?

Nice, can you show us a flow test with water when it’s done? Would be nice to see how it in action.
