Vehicle Sketch Pad Open Release

Hey everyone,

NASA has just unveiled there Vehicle Sketch Pad open source product. I don't know how many designers there are out on diydrones but this should be fun to play with for anyone interested in flying things.  http://www.openvsp.org/

The Relevance of Propellers

Hi again. Latelly I've been testing some different propellers on my quad and checking the main differences between them. For my emax gt 2218 930kv , my 3S batt and the 1500 / 1600 weight, I was using those cheap 12x4.5 props. I even bought 12 pairs for $25 or so, and one thing I can tell you about them... FORGET ABOUT IT. After 2 crashes from wich I could not tell if it was a motor or prop problem, I decided to test other props. I started thinking that too much flexibility would have a…

Backup system for BEC

So after much reading and research into the whole "backup" BEC saga. I think I've found a solution!

My first idea was just to run a 5.5v backup lipo in parallel with the 5v UBEC output.

This idea has been vitoed by most. Too many unknowns apparently.

The other was to parallel all the BECs up, but this would cause harmonics due to all…

Quadcopters team up as construction bots

More coolness from the Vicon motion capture room of U Penn's GRASP Lab. Quads work together to assemble a structure faster.

Additional Details for the USA Trip I'm Planning

I've had a lot of questions recently about the USA trip I'm planning, and thought I'd provide some additional details about what plane, FPV, AP, RTH, etc system I'll be using for the journey.

Basically, I'm planning on scratch building a twin engine airplane with a 6 -7 ft. wing span. It will fly at 60 - 80 MPH for as long as possible (hope to get an hour or more at that speed). I'll land it, replace the batteries, service the airplane, and…

Reliable takeoffs

This continues to move forward.  Decided attitude sensing is required for what we need.

After some complicated math problems, finally derived an empirical method for determining attitude from video.  It most definitely isn't…

Parrot AR.Drone 2 announced, adds HD vid, baro

At CES today, Parrot announced the latest updates to its AR.Drone. The most interesting bits are higher resolution video and an onboard baro sensor that will allow it to fly higher than sonar range outside. The phone/tablet app also has a better FPV mode. 

Here's the full text of the…

Start of my laser-cut truss QuadCopter

Well, I decided to start seriously designing and building my quad-copter frame.  I recently build a CNC laser and can use that to cut all the parts I need for the frame.  I plan to use polycarbonate because it is strong, tough, and fairly light.  I've been exploring ultra light design principles.  The idea is that you can use very thin materials to make truss structures that may be quite flexible out of the truss plane but you add enough trusses in the out of plane direction to stiffen up…

Perhaps not the best news for UAS in the NAS, in the USA well private ones anyway.

Its no wonder AV have been making lots of noise in the press about UAS in the NAS soon.

Their man has just been put in charge of the ASTM F-38 committee.

The rules might well be changing and it would seem almost certain that military standards will form the backbone. Best dust off your STANAGs…

Custom Prop spinner for Turnigy G10 810kv motor (with threaded prop shaft)

Thanks to hobbyking for sending POS prop spinners with 8mm prop shafts!

Below are custom ones turned from solid aluminium.

Much stronger and with tighter tolerances. Also I decided to thread the shaft (as in video) and props,

so the props thread on :)

Gonna do some prop thrust test tomorrow.…

Easy Star brushless outrunner mod.

Since I've had such problems with buying a brushless in-runner, I've got brushless outrunner instaed.

To mount it in the plane, I've used motor mount (that was a problem to find in my country too) from the twinstar,

slightly modified.

Pictures will tell the story.…
