The videos of the last flights were posted to youtube weeks ago….

I mentioned it in comments, but I guess I need to mention it here:

Crashing into the crane….

and a good but short flight…

and a long flight with a vane falire at early on…

Its good to have the links on the site. Better to embed the links or if not then add Target attribute so a new page opens up.

The videos are great. Its most interesting watching the stability as Armadillo is rock solid. Your very very close and this is good news for sure. The length of flight two is also encouraging - not sure if its ready for off the tether flights though - that's the big (set of) tests.

BTW: The second link it to the third flight not the second. May be a quick edit is in order.

The videos look fantastic. Thanks for sharing. Building on David's comment that the rocket is looking stable, I'd like to know if you're using accelerometers, gyroscopes, or both? It would be great if you could share the exact parts you are using. I am thinking about building a quadcopter and am looking for some real world experience people have with sensors used in these types of control systems.

I'm using a 10Hz GPS and a microstrain IMU.
I'm using the vertical component of the IMU accelerometer, but not the horizontal accelerometers.
This is a MEMS based IMU. Most of the other hovering rockets I know of use fiber optic gyro imu's.
(I think true zeros was also mems, but I'm not sure)

Thanks for the link. I didn't see it before.

FYI, TrueZer0's rocket also used MEMs. Great flights sir.Look forward to your next test...I'll probably try to make it as I live in Lancaster.
