Did you already try this on your copter or is it just a SIM implementation?

This is a Hybrid implementation using Quaternions and DCM.

Add a backup battery on the MTK GPS module.
Posted on May 31, 2012 at 2:28am 36 Comments 3 Likes
Hello Everyone, we all know our GPS board (the one that comes with the APM1) has no battery to backup data.
This has the disadvantage to make the GPS not very precise in the first minutes after power up and that every startup is a cold startup (at least one minute to get a 3D fix).
This is because the GPS needs find the satellites without a…

I can finally post a video of my quad. This is my 2nd FPV flight ever.
I was a bit nervous, but the latest AC2 firmware 2.0.39 proved to be rock solid!
Weather conditions were the best ever so I couldn't miss a 7 o'clock flight... :)
Nothing special in the footage apart the stability of the quad that needed only little…
5 flying modes with a Spektrum DX6i
Posted on June 30, 2011 at 9:56am 11 Comments 3 Likes
This is my little help to those who want to fly 5 modes with their 6 Channel TX.
Unfortunately the DX6i has only 2 Pos Switches. If it had a 3 pos on the 6th channel, the we could use 6 modes.
But anyway this is How I did it:
In the SetUp menu go to MIX1 and set:
GEAR --> GEAR ACT
RATE D -50% U 0%
SW ELE D/R
Then go to MIX2 and set:
GEAR --> GEAR ACT
RATE D -100% U 0%
