Auto Flaps

Hello everyone!

I'm working on setting up auto flaps for landing and takeoff on my aircraft. I followed this: http://ardupilot.org/plane/docs/automatic-flaps.html, but I can't seem to get the flaps to move on my benchtop when I put the Pixhawk into FB

PreArm error blank

We're trying to arm our plane with ONLY the PreArm check for INS turned on (16, bitmask 4). However, the Pixhawk fails to arm and returns the error:

"APM: PreArm: "

And:

"Got MAVLink msg: COMMAND_ACK {command : 400, result : 4}" When running on MavProxy

Lighter than Air Regulations in US

Hey guys - 

I'm new to lighter-than-air flight (been working on planes for a bit) so I don't know the regulations behind them. I'm looking to both fly a lighter-than-air drone just for fun - however I'm looking to bring it into my research in the futu

Pixhawk not controlling servos

Ok, this is an odd problem. Here goes:

I have the pixhawk armed without GPS (solid blue light, APM Planner says "armed").

Pixhawk is plugged into my computer over USB

BEC powering servos (well, one servo at the moment) by it's plugged into the AUX rail.

Lose all servos on takeoff - Pixhawk

Hello,

I've been using a Pixhawk for a while and I've never had this happen:

We calibrated the accel/compass and gyro when we arrived at the field

All sensors looked good after calibration.

On the ground all of the servos worked (tested throttle as well)

Pixhawk Servo Reversal Fixed Wing

Hey guys,

I'm currently running my Pixhawk with the PX4 autopilot project firmware (found here: https://github.com/PX4/Firmware), also the firmware that is loaded through QGroundControl. I need to reverse the servo output for my ailerons, and I can't

Brushless motor replacement?

Does anyone happen to know a good replacement for the HXT 2835 (380S) 2200kv Brushless Inrunner? (Can be found here: http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=5203) It has been out of stock for a while, and I do not know how

Mini telemaster

Has anyone used the mini telemaster before as a UAV platform? How did it perform? Are there any other planes within this price range ($150-240) that are better then the telemaster?

Helicopter UAV?

Hello,

Plane Designs/Good planes

I wanted to make a form where people could post their plans for airframe design, and planes that they used that worked well (we know about the easy star, telemaster, and easy glider) I've got one that I think would be really good.It's a giant gliderH

$150 UAV platform

I've been looking through the posts and I haven't been able to find a UAV platform (with batteries, motor, and motor controller, don't need RX/TX) for under $150. Even the Easystar without the RX/TX is still $192, with the higher powered motor. Does

GPS and Gyroscope boards

Ok this is my first UAV and I'm designing my own board (with a PICAXE 28x). Does anyone know of good GPS and gyroscope evaluation board or chip that is also inexpensive? I've looked at the Parallex GPS, but I haven't found a good gyroscope.Sam R.

VB.net

Any have an idea of how to use the USB port in VB.net? I want to make a ground station for my UAV (I would like to build it myself...), but I can't figure out the USB connection. I'VE SEARCHED EVERYWHERE!!! Any have ideas???Thanks a bunch!Sam R.

Piper Cub airplane design

I am a first to building my own airplane, and a first to UAV building. I found a cool RC plane that I would like to build, and I wanted to check it by everyone to see if it might work. All I need is room for my autopilot system and a little room for
