@DanInvents More of a road dart. :)

Sometimes you hit the shutter button at the right time...

@kegrocket Bolt on a piece of round bar on the end with 3 bolts. Then grip the round bar.

Our club does a few outreach events every year and having something interactive for kids is always fun. I've made a controller they can use to "launch" rockets. It plugs into a USB port and runs a local webapp. The controller is made from the guts of a cheap $5 USB number keypad.

@joebarnard Next challenge, vary the grain and core geometry so that when the motor burns the thrust curve writes out https://t.co/hV3ce9SVNa in cursive. (or at least in Morse code)

@kegrocket @TurbulentSphere In Australia an M1297 reload will set you back about AUD$1,067 (~USD$700) and a M1939W costs $2,435 (USD$1,585)

Many model rockets have a fairly empty airframe. Why not fill that space with compressed air and augment the thrust of your solid motor for more performance? The proof-of-concept AirHawk successfully flew twice today! Video coming soon. (100psi + C6-3 motor).

@BenKrasnow Awesome video Ben. I've never seen the process of welding in such detail. Keep up the great work!

[George Katz @AirCommand]

This is AirHawk. Looks innocent enough. We'll be testing 5 new concepts with it tomorrow. Lots of unknowns. The bottom end looks strange. Can't show the launcher as it may give clues to what we are testing. If all goes well, we'll scale it up!

@joebarnard Joe looking to set up a 'Math' Lab in the desert :)

Here is the full length video of our World Record flight from last year. It goes into details of launch day operations, the launch, and flight data analysis. Includes special announcement at the end of the video. https://t.co/OK0z58oZsX

@joebarnard @parkerjwaugh Here is one coming in hot ... https://t.co/fGCMZP169g

New Horizon video is now out! https://t.co/46E8vATO55 I thought I'd try a different intro/outro this time. It sure got plenty of looks at the beach. :)

[George Katz @AirCommand]

Almost finished Part #42 of the Horizon series video. It took a bit of time to edit this one, it will be about 24 minutes long. This video covers us finishing the rocket to get it ready for flight. The next video after this will be the full length launch day operations.

[George Katz @AirCommand]

Part 40 of the Horizon series is now out. https://t.co/mO51SoDayJ We cover the booster's parachute deployment, it's twin camera package, and the upgrades to the sustainer deployment. We also perform booster electronics flight tests.

[George Katz @AirCommand]

Happy New Year! I'm finally getting around to finishing the next video in the Horizon series. This one covers details of the parachute deployment mechanisms. I'm hoping to have that done in the next few days.

[George Katz @AirCommand]

@CodysLab Perhaps the missing anti matter ended up inside of early black holes alongside regular matter? It's not like it is getting out but we will still feel it's gravitational effects.

[George Katz @AirCommand]

@joebarnard Good luck Joe! The main question is... BBQ sauce or not?
