Which 22xx/28xx motors are most efficient for 3S batteries and +/- 10"-11" props? There must be some that outperform the usual crop of cheap eastern outrunners that aren't too exorbitantly expensive?
I (like many others) want to maximize flight time w

Can the current offering of the APM: Plane accommodate a modification to use a camera (such as a Canon PowerShot) as a payload shooting straight down?
The pictures for this product appear to only show a forward looking camera, more suitable to FPV.

I am building my first 3DR Quadcopter and i am having trouble calibrating DX8 to APM 2.6. I have followed the "connecting the RC inputs" guide on APMcopter on how to wire the RC Receiver to APM and had no luck calibrating the radio in mission pla

Read more…Hi All,
We've taken a 3DR Quad and changed it a bit to try and get more payload and more flight time. Here are the current specs:
Motors: T-Motor MT3520-11 400KV
ESCs: Phoenix Edge Lite 50 Amp
Props: APC 13 x 4.7
Battery: Zippy 5S 5000mAH
RC: Spektrum DX8

My questions are around the "where is a firmware to my px4 for HIL"
I try to charge a firmware with mision planner (2.68, 2.69, 2........).

This is my third crash (repeating the 'exact' same scenario deliberately) in the past two days. I have found the core problem of the issue -> Using camera (RPi camera module) on-board the flight wipes out GPS signal 'entirely'.
