"@CrashPilot1000 - Delta planes turn by using a mixture of aileron and elevator functions.  When the pilot is flying straight and level and pulls front or back on the elevator control, the plane will move (pitch) both elevons in the same…"

"I can produce wings up to 110 cm from the foam blocks I have available, so a wingspan of 220 cm + midsection is possible... I will have to wait for the 32SWG nichrome wire to cut that kind of length with the power supplies I have available. The…"

"It's GoPro Hero, very nice camera, if you can stand fisheye effect ;P I think it should be even larger than 140cm, maybe 160-180cm and specialized flying wing airfoil (quite thick, more space to equipments), 500W+ motor. Ritewing II like.…"

"Tero, that is a nice wing! What camera was used for this video? My next project is to build a larger plane with more wingspan, I want something that flies well at slow speed, and with enough carry capacity to handle full autopilot and fpv setup."

"I have something similar: 140cm span, 10x6 prop, HK Donkey ST3007-1100kv,40A ESC, Rhino 3700mAh 3s, about 1kg, little bit underpowered. Airfoil NACA 2412 / 0012.  At the beginning of the video you see that plane with full size elevons…"

"Get yourself a proper electric prop performance will improve, an APC thin of some sort. Add some fins as well you will need them."

"The ESC on the bottom just fits nicely with the length of the wires and the CG. I might recess it more and add some padding, but I have a few of these ESC's around so I'm not too concerned about it.  It may be slightly…"

PeteD commented on Eirik Mikkelsen's blog post Self-built flying wing
"Why put the ESC on the bottom? I don't think it will last long there. Have you test flown yet? Prop should be ok, the only specs I could find are here: http://www.uberallmodel.cz/index.php?id=15&lang=en. How much does it weigh? I get…"

"Great tips, thank you! I had initially limited the range of the aileron servos on the radio, but placing the rods like you say will of course allow full movement and resolution of the servo and should be smoother. SaadTiwana: That is clear…"

"I always wonder how deltawing pilots give "rudder". I think they do a small roll and pull "elevator" - anyway it must be really fun to fly these tings! Rob"

"Hi. Nice wing, good job! Your wings have a shine. Did you coat them with something which gives the smooth surface/shine? -S "

"Great looking wing, very similar to mine although my wing section is thicker to carry extra weight at a slower speed.. I see 2 small issues as it is.:- 1, A flying wing will always need reflex in the rear of the wing to create drag and provide…"

Self-built flying wing

One of the glass fibre arms of my quad shattered after repeated hard landings on a hard-wood floor, so I have some carbon fibre replacement arms on order. Meanwhile I thought it would be fun to experiment with foam cutting and trying to build a plane from scratch. With inspiration from MyGeekShow I decided to build a flying wing design…See More

Eirik Mikkelsen commented on Eirik Mikkelsen's blog post Update on first APM 2 quad build
"I don't think the design of the legs is of importance, in fact the 3DR ArduCopter frame has the legs mounted closed to the center of the frame and tilted outwards. There are also frames with helicopter style landing skids."

Profile Information

About Me:
I used to be a programmer by trade (C, Fortran, Haskell, Common Lisp, Python, Ruby on Linux, *BSD and QNX RTOS). At the age of 32 I decided to go back to university, and now I have completed a BS in physics and is currently writing my master thesis in theoretical cosmology. I have loved flying machines since as long as I can remember.
Tell us a bit about your UAV interest
I'm building a quad copter based on APM2.5. The quad is now complete, and I have a stack of XPS foam which is waiting to be cut into a flying wing UAV.

This is an update to my previous post about bulding my first quad copter. Finally the most important packages from China & Hong Kong has arrived, containing the motors and the new Hobbywing Quattro 20A ESC / 3A BEC. 

I have also purchased the Turnigy 9x which was quickly updated to the ER9X…

Building my first quad UAV

Posted on August 18, 2012 at 6:00am 2 Comments

Just thought I'd write a post describing my first quad build.

Parts list:

  • Hobbywing (or clone?) X-450 glass fiber frame (205 g), x-configuration
  • APM 2.5 with U-BLOX GPS
  • Electron 6 channel 35 MHz receiver (Hitec Optic 6 transmitter)
  • Hobbywing Quattro 4x20A switching ESC (no power…
