Multiwii 2.2 (gimbal only, 0 motors, no R/C) on an 1/10 R/C gas car. WinGUI (distinguisable at 1920x1080) captured on laptop.
Arduino with MPU6050 (default filtering) and HMC5883 sensors, oriented as in Crius SE V2.5.
I2C GPS also installed, but moreless symbolic.
Data transmission with 3DR at 57600 bps.
Aditionally, beautiful gas car noise for free.
Shortly, the same on an 1/5 R/C bike, after having discovered how to change scaling on WinGUI.
Hopefully, bike inclination will be clearly seen (here are seen accelerations and brakings on the horizon line).

Changes from above version on car:
Changes from above version on car:

The Camera stab works really god..
Telemetry seems a bit slow.

Apparently. There is an inherent limitation, since the bike swings around 120° (60° to each side from vertical) and the servo does 90°.

I forgot to refresh at 10 Hz (Win GUI), so it was captured at default 5 Hz. I'll try to remember this next time.

Same with GPS trajectory on Google Maps captured.

that is awesome!

Battery current, voltage and power graphs in real time.
Current is sensed with a Pololu ±75A ACS709 Hall effect-based linear current sensor. Voltage is sensed with a resistor divider. Power is the product (shown inverted for clarity).
As expected, current is always positive (no energy recovery when braking).
Although MultiWii mw-wingui can graph debug variables (see attachment and MultiWii.cpp) graphs captured were obtained with Starlino's Serial Chart (http://starlino.com), and a special program on the Arduino which simply samples, filters and sends values in ascii, according to Serial Chart required format (simply CSV).
