Just found these videos. Has this German gentleman posted anywhere here? No links to any tech info other than that found in the text comments in his videos:

Gyro Chip: MPU6050 with DMP
Prozessor: Atmega328 on 8MHz (possibly a 3.3V Arduino Pro Mini)
Servos for Motor Gimbal: DYMOND DS37 (Weight: 3.7 g; Torque: 4 Ncm)
Battery : LiPo 3.7V 130mAh
Rocket Motor: Klimas
Stabilization loop runs at 100Hz
Diameter : 57mm
Length : 220mm
Takeoff weight: 128g

Short (and darkly lit) video segment of his operating gimbal mechanism shown in this one:

His last of four videos. System appeared to work very well:

I sincerely hope not. This hobby doesn't need a reason for the alphabet organizations to look our way. We don't need this.
 
So what happens when the motor burns out? With no thrust to vector, it better be aerodynamically stable at that point, or you've only succeeded in raised the altitude at which it will start skywriting.

I have seen threads here before with technical details about successful thrust vectored rocket efforts. This is one I haven't seen covered here. Besides, it's going to take one HELL of a lot more than what he or anyone else has done in our hobby to make our rockets a threat. There is absolutely no comparison with the FPV RC hobby where there is cheap and highly capable off-the-shelf technology which might be misused.

A few thrust vectoring threads I can find right now although I thought I saw another one here by a female who had specifically used an Arduino just as this German gent did. Maybe I'm thinking of a NARAM tech report from NARTS?

Attitude control thrusters! LOL.

Actually, rubber band loaded pop-out fins controlled by the same vectoring electronics would be useful although the whole point of the thrust vectoring, at least in this case, is not to create a low drag altitude model but a more accurate scale model and, of course, just for the sake of doing it because it's so cool.
 
I think that vector control is great as long as the goal is to have a rocket flying like the real one without additional fins. I am glad to see that more and more people are trying to improve it and maybe one day I will have a go at it. I have been looking at BPS

and that guy is doing a very good job.
However even with long burn solid motors your power flight duration is less than 10 seconds. It would be cool to have liquid motors or something that last longer.

My only concern is that whenever you fly one of those at a public launch it better work well.... our rockets are quite safe because unlike planes or drones they fly vertical.
So it is great but you better know what you are doing, it is not like any other rocket electronics, it is not plug and play and it needs to be adjusted depending of the shape of your rocket.
For those who have built their own drone, same goes for the rocket , it also has a control loop system, you need to adjust your PID's. But unlike a drone where you can do auto-tune with a 5 minutes flight, with a rocket you have 10 seconds max so it is a lot harder to get right.

Yes, the hobby has problems even with finned rockets with bad CG/CP issues. However, at least from what I've seen so far, anyone with enough knowledge to tackle a vectored thrust system is smart enough to realize the hazards.
