Grettings all.
After the loss of my last AQ I have been wandering the multi rotor wasteland.
Not quite but it sounds good
While this may not be the most efficient build I wanted to try it out after seeing the fuss in this thread.

Unfortunately the mfg has not given a firm release date.
The smaller one has been on preorder for months.
Their Facebook page shows the small ones arrived to them in feb.
The bigger one is being redesigned.

Weight has not been optimised
The only tuning so far has been to drop the Tilt Rate D from the default down to 2000.
It was saturating the motor outputs.
I forgot how smooth the AQ is compared to others controllers I have tried.
Excuse the mess, it is a experimental platform after all.

Also have a YS-X6-P coming back from an upgrade that I should be able to compare it to.
The frame is just big enough to install 15" props.
They will be rather close together though.
The frame is ridged as advertised.
I could potentially get a lighter weight rim, 250g? by going with 2mm CF vs 3mm on this one.
How does it compare to a regular arm type build?
I don't have one to directly compare it with.
In theory, if I made the center arms less rigid, the weight of the center place could act as a dampening mass for everything attached.
The plan was to build a heavy lift so upgraded planned fro the AQ were,
.Upgraded Recoms
.Change the voltage divider to handle 6s
.Feed the spare ADC (unused pressure sensor pad) with a current sensor
The tricky part will be modifying the source for the different voltage range.
Adding an extra logging parameter fro the current sensor.
How did I loose the last one?
Overconfident pilot and suspected broken prop.
It was being used in a MilSim War game, Airsoft.
After many successful missions during the day it went up at night.
This was the 3rd night flight.
While I had a working GCS link I did not cache the map of the area before I headed into the field.
A carbon prop had cracked earlier in the day after a hard landing.
I failed to bring any extras into the field.
A quick repair with some kapton tape and it worked good as new.
While in a hover it started to toilet bowl.
I managed to manoeuvre it away over a safe area.
This was easy as we were on a small peninsula, surrounded by swamp.
I went a bit too far into the swamp when I cut power.

At least it will be well preserved
Many lessons learned the hard way.
