3DR Y6 flight times

I'm curious what kind of flight times people are getting with a stock 3DR Y6?  We flew last week with a fairly light payload (Tarot T-2D and GoPro) with a 5400mAh battery (Thunder Power G8 Pro Lite), and only got about 12 minutes of flight time.

Help with Hex Crash

We we're doing an auto flight this past Friday with our 3DR Hex.  We noticed the altitude started climbing (all waypoints were set to 50ft) and transitioned to loiter to bring it back down slowly.  This worked fine and we got back down to around 50ft

Throttle Failsafe in Action

We tested the throttle failsafe and RTL function in 2.8.1 and posted this video of it for anyone curious as to how it works.  We were quite nervous about recovering the vehicle if it didn't work, and the momentary throttle cut was unnerving, but it r

Cumulative Current Usage

A while back Mission Planner gave a percent usage for the battery that I assumed was based off the current data.  More recently that display has switched to the live current data.  Is there a setting in Mission Planner to go back to that previous per

Long Duration Hex

We just completed the maiden flight of our 3DR hex.  We're trying to optimize flight time, hence the large quantity of batteries.  Here are our basic specs:

 

880kV Motors

12x3.8 SlowFly Props

APM 2.5 w/uBlox GPS

AttoPilot 180A voltage/current sensor

FTS s

Loss of RC inputs during flight

We had an unusual failure and need help analyzing the logs.  We were flying our 3DR Quad Frame with an APM 2.0 with MediaTek GPS and ArduCopter version 2.7.1.  After taking off in stabilize mode, we lost control from the RC (Spektrum DX6i & AR6115e)

GPS Data for Payload

I have an imaging board that needs to have GPS data to go along with the pictures it takes.  I'd like to not have 2 GPS units on my vehicle and instead somehow output the GPS data that the APM2 has to this imaging board.  Are there any available seri

Help solving sonar problem

I've been struggling trying to get reliable altitude data for my quad.  Whenever I try altitude hold, it'll continually rise or fall, but not hold any sort of steady altitude.  In testing I've let it get to the point where it landed and where it rose

Using 3DR frame with 8 motors

Is it possible to mount 8 motors on a 3DR frame?  This would be 2 per arm, 1 pushing and 1 pulling.  Could this be a realistic upgrade for increased payload and/or motor redundancy?  I realize the power board would have to be replaced as well, is the

3DR camera mount

I'm interested in a small camera mount that can mount under a ArduCopter 3DR frame.  Ideally I'd like 2 axis control and be able to mount either a GoPro HD Hero or a smaller canon or sony point n shoot to it.  Any suggestions?

QuadCopter Build for AP

I've been watching this site for several months and have decided to jump in.  I'm building a Quad for fun and for AP.  I want to use the more popular and tested parts since I'm interested in a Quad that works in its initial config.  Once I get some e
