This is the flight controller, it has and does most of those things.
Controller was mistakenly set to hold liftoff orientation rather than
reorient to upright from the accel/gravity readings - operator error.

USB would be nice. Bluetooth is possible as well. It’s got much higher
latency (10ms), but not so much that well-written software cannot work.
That makes the physical fit easier, and also allow placing the android and
the servo/control model on opposite sides of a parachute compartment if
that is beneficial.

Didn't watch the entire video so don't know exactly what you did, but it
was great. But, while sitting on the launch pad your flight software should
be integrating errors out of the accelerators while motionless, figure out
where gravity is, calibrating and aligning . After liftoff, the errors
should be integrated to re-trim the Thrust Vector through the C.G. so the
Rocket fly's straight instead of at an offset.
Have you thought about using an Android Phone for your On-Board Computer
and Sensors? It could reduce your overall mass of the individual
components. Most phones have a fairly complete suite of sensors including
dual cameras, multiple radios, 3-axis accelerometers, 3-axis gyroscope,
3-axis Magnetometer, barometer, usb interface, fast multi-core
processors... The phone would still need an interface board (usb) to read
(sensors) and write (commands) to the rocket hardware.

Hey that’s mine! More luck than anything, the thrust curve matched the
prop mass loss really well. TVC setpoints were a little off which is why
you see the slide to the right.
