EagleTree Systems in the Yakk 34'' What went wrong?

 

Although it was a short lived flight it was fun. I always enjoy flying with my Pops, what makes it better is that I have both video from the ground and onboard the aircraft.  This helps identify what mistakes I made and why I had an unsecessful fight.

 

  1. Over wieght .........aircraft not me LOL!!
  2. I was flying to LOW
  3. I was flying to SLOW
  4. I was facing the…

This is a true FPV plane thats easy to build and comes packed with common sense FPV must-haves such as rear mounted servos for the elevator and rudder to help counter balance the additional radio gear. Other practical features include the large internal ply mounting trays for attaching large amounts of equipment in the desired…

MatrixPilot 3.0 released!



The MatrixPilot dev team is happy to announce that version 3.0 is finally out the door! This update includes a hefty code reorganization into modular, reusable libraries, along with some important new features, and refinements to our dead reckoning and wind estimation algorithms. The code should also now be much easier to hack on as a basis for using the UAVDevBoard for other purposes.

Thanks to all the developers and testers who helped out with this…

My PROJET MQ-9 Reaper 98" Build

Control Diagram finished 4/28/11

I know these servos are cheap but have some pretty good reviews, I hope they can handle well.  The reason I chose to use 8 mini servos as apposed to the recommended 4 mini and 2 standard is to try to make space.  How you wonder?  Well being able to eliminate the linkage cables in the plane I plan to build an access panel under the plane…

HEXA frame continues: Anti Vibration Motor Mounts

step by step, the HEXA frame is being constructed.

haven't worked on it for a while, but now i'm done with an interesting part:

 

 

 

I used the original arducopter motor mounts (the plates that come with the motors, which are not used on the official arducopter frame)

to be tied on the square arms, and between the mount and the motor,…

Nice!

"You ready to rock and roll, man?” I still didn’t believe what was about to happen. I looked up through the clear glass cabin roof, knowing that the next time I looked up, I’d be staring at the ground below.…

Easy camera roll stabilizer to APM

 

This is easy camera roll stabilizer to ArduPilotMega (I used code version 2.012). Camera mount was easy to build. Camera angle can be adjusted during flight with RC controller. Stabilization needs only one line code to program! Of course also pitch can be stabilized in the same time, but I have not yet tested this.

Camera stabilizer is normal mount with… Continue

Turnigy 9c Transmitter Burned Up!!!

   As we all know the Turnigy 9c is a great radio for the $54 price @ Hobby King and is very user friendly. I want to warn everyone about acidently connecting the battery backwards, BE VERY CAREFUL if you connect the battery backward and turn on the Tx you will destroy it immediately. This Radio Tx does not have a fuse that can be replaced.

I had my radio 4 days.  I wanted to use a LiPo battery pack instead of the "AA" holder that came with it.  I some…

Deciphering bird flight, scientific way

There was a lot or rumor about the Festo Smartbird in the last weeks. They actually built a nice bird, mainly by simulating and trial and error (see the movie posted lately Video).

Now scientist go to the roots, letting an owl fly through a bunch of cameras measuring the movement.…

APM flying a search pattern with a SkyWalker

After yesterdays transmitter failure, we flew the SkyWalker again today with Jacks Spektrum transmitter. This time everything went very well, and we successfully flew a search pattern over the CMAC field.

The flight we did was:



 - takeoff in fly-by-wire-A mode

 - switched to GPS loiter, worked well

 - switched to full auto, and flew a "mow the lawn" 18…

Another quad in the sky

I've been working on this quad for about three weeks. I based some of the frame design on the arducopter. The flight was done with the ardupilot mega+gps+compass in stable mode. The start was a bit disappointing at first, but it was soon resolved and possibly caused by a faulty RSSI indicator. As can be expected, it's way more stable than the tricopter. The only required nudges are throttle and where the quad is going. Soon, I'll test GPS Hold mode and a mode for navigation that I put in…

Yet Another Build Log (YABL) - Part 4 - Sonarrific





I've originally meant to write about propeller mounting, tracking, tightening and about my first flight (which ended up with a stripped spinner nut), but since my sonar arrived and, since installation wasn't exactly 100% straightforward, that's today's subject. So, here it is, in the photo above - the Maxbotix LV-EZ4 sonar, freshly taken out of it's zip-lock baggy, along with a 5 pin header. Which is not included. That's from my own header stash. NOBODY TOUCHES MY… Continue

"Team Zyzzyx" SparkFun AVC 2011 Ground Entry

First off, a big thank you to the hardware and software developers of the APM autopilot. Without it I wouldn't have been able to pull off a working autonomous system in such a short time. Thanks as well to Jack Dunkle for helping me out with a late encoder addition.

 

A couple months ago I saw the SparkFun AVC announcements and decided to enter. I bought parts early, but didn't get it all working right until…

Foamaroo First Flight

 

We had a very successful flight on the Foamaroo prototype yesterday.  The Finished airframe came out at 2 lb 11 oz complete with 2200 mAH battery.  It was windy yesterday with 15 know winds and the Foamaroo handled the conditions very well. 

 

After a short trim flight I was able to launch the plane with a single handed toss and was happy to see…
