DIMU with very short full calibration results
Posted: Tue Dec 10, 2013 2:30 pmHi Guys,
This is a short demo vid i shot this morning with the upcoming DIMU (and full CAN enabled ESC32 communication). The DIMU has a new simple calibration option that I tried last week with very good results.
In this demo I wanted to see the results from a full calibration (freezing, warming up, dance and calculations) and if possible within one morning. I started around 7:00 am and took the vid around 10:30am the same morning.
Hours spend: freezing, warming up: ~75 min (1 file)
Dynamic dance: 7 min (1 file)
Dynamic calibrations:
Step 1-3: ~15 min
Step 4a & 4b both 50 loops ~10 min
Step 5 150 loops ~30 min
Step 6 3500 loops ~30 min
As you can see very short loops:
In total just under 3 hours on a core i5 (first gen) notebook.
I'm very very pleased with the result: it is a quad with slow turning motors and large 15" props so mind you that in mild wind like in this vid it can be less stable than fast turning props.
The alt hold is impressive and during the RTH or forward DHV flight it did not change altitude at all.
It proofs that full calibration is still very useful for the temperature compensation (-5 degrees during vid) and magneto offset based on your electromagnetic profile but it does not have to be a long session. I am very curious about the other results when the DIMU will hit the market.
