When trying to takeoff in Alt-Hold, sometimes my motors surge, and the heli jumps about a foot in the air very fast. This has not been a problem, as I usually just handle it by continuing to gain altitude and the heli settles out and flies normal. I'

Read more…はじめまして、UAVによる空撮の研究をしているEndoと申します。
初歩的な質問で大変恐縮ですが、xbeeとレシーバーの使用についてご教授願いたいと思います。
今回missionplannerとpixhawkをxbee経由で通信しつつ、UAVの操作を試みたのですがプロポの電源を入れた途端、xbeeの強度が激減してしまいます。PCとUAVを10mほど離すと完全に切断されてしまうほどで、tlogといったデータを取るのが困難になっています。
おそらくxbeeとレシーバーの周波数2.4GHzが干渉しあっている
I know that sounds strange. My receiver (Orange R910) is all PWM. I just got some LEDs from Flytron. These LEDs can use a PPM signal to sync the flashing. Is there a way to:
A) Get the APM to send PPM instead of PWM out one of the outputs?
B) Someth

I have a MinimOSD (original 3DR) running OSD Version 2.0 connected to a Pixhawk, running Arducopter 3.1.3
I get a video link - but no overlay from the OSD.
The OSD is powered from both sides (Pixhawk and Camera).
I have tested the OSD to work fine on

I see the the notices that in the USA to use the 3DRadio 900 MHz link, you need a ham radio license.
Ok, I have that (Extra class licensee for many years)!
But I don't see any place in the software to allow my Amateur radi
I would just want to know if there is ayn recommended altitude to test the failsafe in the field? The reason I'm asking this is because the last time I field tested the failsafe my hexacopter rolled to left and crashed. Two broken arms and a couple o

Total newbie here with PixHawk, etc.
I have my new hardware today (Pixhawk, GPS, 3DR Radios, etc). So I decide to connect it to my computer and start learning the software.
I have the PixHawk connected via the USB cable. It seems to work. Get

Really like the look of the airframe, but want to do my own build.

I did build a quad 350 size and I would need some 'default' Arducopter PIDs for this 350 size (Phantom or QR X350) or similar. I have installed the latest FW for Arducopter.
The quad is flying OK, but is too aggressive. Next step for me would

I've been flying my heli for a while but I came across a problem, which doesn't happen quite often but it may be important for safety. It's the power failure and autorotation.
