Building Tandem Rotor Helicopter with OpenPilot

Posted by chinlin0924 in RC DIY Blog, 15 June 2013 · 66 views

Hello friends,



I am trying to build a tandem mixer with openpilot.
This is my tandem helicopter frame for testing.
The mixer is still under development & testing.
The idea is simple, but still needs take much time to put into practice in openpilot.
I am new to ARM microcontroller. I took spare time in weekend to develop my hobby.

900 MHz pepperbox. OMFG!

Posted by thefokker in thefokker aka Dave's Blog, 05 June 2013 · 247 views

So... I got myself a new antenna. I like going far and low through the trees using 900 MHz. Some may think I'm crazy for sticking with 900. When it works, its soooooooo much better than 1280 or 5.8

I've used a 900 crosshair. Works great!! It's big

900 5 turn helical. Works great!! It's bigger

900 MHz pepperbox. Works unbelievable!! It's monstrous lmgda...

H - Quad * A build log *

H-Quad - a build log  


One thing that I discovered while building and tuning my brushless gimbal for the Tricopter was that I wanted and needed something else to fly. For me, there is not much point going out with something like a gimbal that you can’t use because it is not working. I have been threatening to build an H-quad for awhile now and since th...

Parts needed:

2x Servo plugs (or 1x 2x3 Pin (2.54mm) Crim...

18/05/2013 La soudure ... ma passion !
Après avoir bien galéré à souder les prises sur la CC3D (Journal #2 ), cette fois-ci c'est pour connecter les ESCs à la carte CC3D que je me fais violence.

Les fournitures pour l'opération :

HRLV-MaxSonar MB1003 High Resolution Ultrasonic Range Finder

Posted by Jurek in Jurek's Blog, 15 May 2013 · 145 views

Hello Friends,

Today i had a chance to test the HRLV-MaxSonar MB1003 High Resolution Ultrasonic Range Finder. Got it for 25GBP from a local supplier.



The interest in this component comes from a very nice specification and some good (astroturfed) reviews of it on the web. It is specified to 1mm accuracy when the 2Hz filter is enabled, and 2-5mm accura...

so, my little home baked quad  has taken a real beating the last few months while i've been learning to fly FPV, been a really good little flyer but it's not as precise as i want it to be any more, everything's bent and hanging in there with cable ties, really sloppy.

i wanted a new frame, but, i'm a real tight ass, my haircut will tell you that(kitchen...

Building a Backpack Groundstation for FPV

Posted by friesianflyer in friesianflyer's Blog, 09 May 2013 · 265 views
groundstation, FPV, 2.4GHz

After being inspired by many other backpack groundstations, I abandoned my plan for a tripod mounted, or flightcase mounted groundstation, and decided to [s]blatantly copy  draw on other's experience....... ;)

I decided to use 5mm foamboard for the backplate, due to:

1. It is lightweight
2. It is easy to cut and drill
3. I had some in the garage.........

CC3D FLIP FPV

I finally had time to build a quad based on my kickstarter cc3d that I received last December. I selected the Hoverthings Flip FPV because I wanted a sturdy frame that could accommodate a FPV setup.

The current configuration uses the following components

No! Tri not. Do, or do not. There is no tri!

Posted by PeteTheRanger in PeteTheRanger's Blog, 06 May 2013 · 160 views

....with apologies to Master Yoda...


It flies! Woooot!



I will install a CC3D as soon as I can extract it from my Bixler.

Mostly happy with it - I did meet most of the design goals - namely that she'd carry the GoPro on it's case and also a reasonable flight time (10 minutes achieved).



She's kind of fat - 1539 grams!



A few LEDs so that my...

Hexacopter CC

Posted by martin in martin's Blog, 05 May 2013 · 87 views

Not in english. Excuse me.

Основными идеями при проектировании нового коптера были:
1. Ноги и крылья должны складываться. (ибо предыдущая гекса с трудом влезала в машину).
2. Избавиться, насколько это возможно, от высокочастотной тряски коптерного мозга. (Используя демпфирующие резинки в креплениях крыльев, и креплением мозгов к площадке аккумуляторов. П...

FPV Backpack Groundstation v3.0 #2

Posted by The RevKev in The RevKev's Blog, 18 April 2013 · 292 views

So progress is slow as I am working with my engineer brother-in-law on the design.  He is drawing it up for me in SolidWorks and we are working on a first modeling of the station.

Included are some pics of what it will look like with 2D scale cutouts of the components that will go in the station.  I need time to cut out more foam to make them 3D so we ca...

Posted by muralha in muralha's Blog, 30 March 2013 · 348 views

Finally tried FPV.

Test 1  - FPV with TX
Test 2  - FPV with Joystick (OPLink connection)



Info:
Quad with CC3D
Default PIDs
Unbalanced props... (do the harlem shake)
3.5" LCD with 16:9 cropped... (something missing up and down…)
[s]2.6mm  3.6mm lens... (very narrow view to fly a quad...)
and I think the camera is out of focus...

Step 5 - Make a Few Mods...

Posted by YouMadeMeDoIt in Second Quadcopter Build - Jago's Heavy Lift, 23 March 2013 · 298 views

Just made a few mods on the Jago Heavy Lifter!

I re-attached the front servo arms via heavy rubberized mounts, and scratch designed some new landing gear that will hold the copter precisely 4" off the ground to make room for my lowered camera mount.

If anyone wants the landing gear, they were 3D printed by Polakium Engineering  and ran me around $42 shi...
