During my ground tests, I found that the velocity measurement (in North-East-Down format) of UBlox GPS is not accurate as I expected. The experiment is like this:
1. fix a UBlox GPS unit on a trolley, which is initially stationery;

It seems that CH4 dead zone (YAW) is very large (1000) compared to other channels.
The problem is that this value is not substracted from the yaw output.
So when you push the Yaw stick, you need to push it a lot to get a Yaw action, and this action

I always thought the front was the side of the boards were the GPS connector is.
I'm not using that. I'm actually using Rusty's frame.
The pics in the manual show that the board is actually at a 45 degree angle when using the X frame.
Here is the pi

I've had a look at the simulation (HIL) capabilities described in the manual and that seems a really great way of improving one's flying skills safely. However, is it only applicable to aeroplanes at the moment?
I am still at the stage of lear

I mentioned in another post that I use a pre-flight checklist to help prevent avoidable accidents in the field (e.g. forgetting to put TX aerial up) , and Chris suggested I posted it, so here it is:

I think there is a typo inside first line of motor test output_motor_test() function :

Should be replaced by
