Two months after finding out that the Zenmuse H3-3D is NOT a standalone device, i opted for the official version, and bought a NAZA M V-2 flight controller.
expensive flight controller in a RC-car doesn’t really make sense at first, but considering the massive amount of functions it hosts, it does make sense after all.
With the NAZA-MV2 fully integrated i could use the following functions:
- GPS waypoints, means i can set waypoints on google maps and the car drives autonomous.
- Steering stabilisation, means it countersteers on slippery ground or while excellerating.
- The NAZA can host a seperate servo driven Gimbal, probably for a second fpv cam etc
- Active (probably servo driven) Suspension, as i can read out the sensor data of the gyros
- Return-to-home function
- On-Screen-Display, artificial horizon, speed, altitude etc in my fpv set.
BUT it also means, that i have to “translate” the flight controllers servo signals to a servo signal that makes sense for a cars steering servo, with an arduino.
The good thing is, that the NAZA M-V2 operates completely standalone, and does not need any servosignals from the Rx to start-up and run. Therefore it just needs power and thats it. There is one channel reserved for H3-3D functions, i will integrate this one of course.
As you can see on the closeup i tried to keep everything clean, and drilled holes in the chassis to ziplock all cables to the car.
The NAZA manual says to keep everything cool, i stapled them on top of each other anyway, but made a small nuzzle in the body that sucks in air. It’s hard to find a flat surface in this car, so that the controller can set itself up on startup, so i had to staple them.
Staying at the shocks, i gotta have to say, my waterballoon shocks-covers dematerialized themself, because of the shocks oil.
So this is not a good idea because the sticky yellow balloon is all over the shocks now.
I added a small plastic mirror which works great.
