Hello,

AC3.3 TradHeli Release Discussion

WARNING to TradHeli users:

Do not attempt to fly AC3.3 until you hear otherwise from me.  I have not even bench tested it yet, let alone test flown it.  There are quite a lot of changes that have gone in that could be crash-o-matic for helicopters.

760uS Rudder Servo Support

Hey guys, 

I've seen the question asked several times over the years, about whether or not Arducopter could support high speed 760uS rudder servos.  I remember trying to help somebody with it a couple years ago, and at that time it seemed not possible

Helicopter Vibration Levels

I just wanted to make a post to specifically address the issue of vibrations on helicopters, as I am seeing quite a few logs which exhibit excessive vibrations. This not only affects Loiter, but can also affect Stabilize as the AHRS system loses trac

Warning about Helicopter Power Supply!

I've posted about this before, but I feel I must reinforce this:

You MUST use a completely independent power supply for your APM or Pixhawk than you use for the Servos.  DO NOT use one BEC to supply both the Servos, and the APM/Pixhawk.

Arducopter 3.2 Warning

Just wanted to put out a warning to everybody, that you should not be testing any of the 3.2 Release Candidates for Tradheli until I say so.

At this time, I have not flight tested 3.2rc1 or rc2. I have been doing bench testing, and they likely will no

Really Good CHDK Script for SX260?

Does anybody have a really good intervalometer script for an SX260?  I've got your basic "Ultra Intervalometer" script running, but would like more functionality.

I'd like something that will run as fast as the camera can. Using fixed focus and exposu

Warning: Flybar Acro Mode

Warning of an important bug.

Do not use "Flybar" mode with Acro mode.  When these are combined, the servos stop responding to cyclic input.  If you switch to acro mode in the air, you could crash.

Use of Acro mode with Flybarless selected is totally fi

Anybody flying PX4?

I'm trying to set up 2 machines using a PX4 FMU and IO Board, and using Arducopter 3.1 rc7, and I'm having a lot of problems with glitching that seems to be coming from the Rx input.  It shows up in the logs as blips in the roll/pitch/yaw inputs.  Th

Tandem Heli

I've had a dream for a while of building a tandem rotor heli.  And I think I finally figured out how to do it.  The reason for wanting a tandem is for a number of potential benefits.  Tandems are more efficient than single rotor helis, because they d

How to UDP Uplink/Downlink?

About 1-2 weeks ago, I tried to use the system to actually connect to my quad for the first time.

I have an SGS2, with an OTG cable and 3DR Radio, and an Asus TF700 pad that I wanted to use and don't have an OTG for.

I managed to get the phone to conne
