I crashed. First crash with 3.0.1. The quad was flying nicely in loiter... and then just fell off the sky. I looked into the logs and I can't see anything wrong. Can someone else take a look please? I'm not sure if this has any connection with the…

I was looking at this product:http://www.adafruit.com/products/1452$110. Would those goggles be enough for FPV or should I just save some more money and get something like fatshark?

I can't find it, can someone point me in the right direction?Thanks.

On my quad, one of the motors starts just a little later than the other 3.First I thought that the problem is the motor, so I changed it with a brand new one, but the problem didn't go away. Now I see that the ESC connected to that motor get warm -…

I'm building a pair of antennas for 5.8Ghz FPV, and I'm wondering if the length of the coaxial cable between the connector and the clover matter. A second question I have, for the TX I don't have a right angle connector, so it would be a problem if…

Does "flip" work in 2.9.1 firmware?

Last night I was playing with my quad with the fpv gear on and I could see that the Turnigy rx is losing the signal from the tx after less than 100 meters (going in RTL failsafe), when the FPV transmiter is on. My FPV tx is broadcasting on 1200MHz…

When I'm high up in the air, and I want to bring the copter down, I never know how fast is descending. It would be nice to have a flight mode in which the user controls just the Yaw, Pitch and Roll and the auto pilot controls the descending…

What value should I use for LOW_VOLT parameter for a 3S battery?The default value it's 9.6, but that seems way too low.Every time I try to search "lipo low voltage" I find hundreds of contradictory articles. What do you guys use?Thanks!

Anyone knows the reason why the Optical Flow sensor is not available anymore?Is some replacement hardware on the way?

Before trying the Auto mode for the first time, I want to make sure I know this detail :-)Are all the values in meters or is the application taking the windows defaults, example in US feet and the rest of the world in meters? 

I had my quad working pretty well with the default values, but last night I was playing with the Mission Planer and I think I messed up some values and now the quad is not arming anymore.Is there an option to get all the defaults back, or just a…
