Pretty Armadillo flight
John Carmack to arocket, the Alternate/Amateur Rocketry list, August 31:
We had a nice test tonight.
You can see that we added the 25kg “payload” as barbell weights right above our landing shocks. Might as well move the CG a bit farther away from the gimbal point…
I think we are going to manually trim out the stable tilt, rather than adding another low frequency control loop for propellant balancing.
We are going to Oklahoma this weekend for a 90+ second run, I’ll do a full update after that. This engine doesn’t have quite enough performance for the level 2 prize, but we have another injector that is more than good enough, once we get it to stop melting…
Any updates from Masten?
