Hey Patrons! Okay... so it's been about a month or two since my last post regarding the rocket motor mount for Scout E. This thing is a beast and a work of art, and it's finally in a good place after lots and lots of testing. This video walks through most of that, with gratuitous amounts of high speed footage!

As for the first flight, we've cleared all the major tests so the last steps before we finally attempt a launch and landing are a few updates to flight software, a little more simulation, and vehicle assembly! Still feels like we can do it in October, we'll see :)

Blue Skies,

Joe

How do you plan on keeping the rocket more or less vertical between burnout and LM ignition? Ever consider using pop-out fins/panels/grids? Or do you think the TVC will be able right the rocket in time without losing deceleration do to side-force applied during the righting process?

Yessir! Pop out fins are on top of the vehicle, and we've got a really low CM so they've got lots of authority(plus a low CM is great for landing upright!)

Awesome! I knew you'd figure out something. Will they be actuated or just static?

Looks promising! Can't wait to see it in action.

Great Job Joe. Just a quick naive question: which kind of motor igniters are you using? Do you have a video which covers this topic? THKS.

BPS.space

Sure! I use little fireworks ignitors for these motors - you can buy them ultra cheap in packs of 100 or so. They work at very low current and voltage, so they're super easy to light, and quite fast!

BPS.space

Both! I suppose... They actuate in and out on a servo, so they're stored on ascent and fold out mid flight, but you can't change the angle of attack or pitch of the fins, so in that way they're static.

Cool and thanks. I‘m developing a process to make some myself, but in the meantime....

This was so fascinating to watch! I especially enjoyed the part where you threw the rocket up and had the ascent motor eject. It will be so legendary to watch this in slow motion on a real flight! One question/comment I have is, would you ever consider adding mini CO2 gas actuating system on the upper end of the rocket? Its an Idea I came up with just because I feel like you're gonna run into a lot of problems trying to straighten out the rocket on descent, specifically with the upper end of the rocket oscillating.

Hey Joe, Will you post the STL files for the new ejection motor mount?
