^I want to do my lighting like that.
It bothers me seeing red and green used to mean front and back and such. Green is starboard and red is port!

I also really like your landing gear. Ive been thinkig of building something like that, Never thought of just using a helicopter part.

Thanks! I very much agree about the position of colors. It's easier for me to tell the orientation when it is all proper and standard.

I keep the landing skids on with zip ties and the frame can slide around on them a bit. It takes some hard landings well, and I've been really impressed with the flexibility of them.

That was my thought too, and i added red and green lights to my first quad for port and starboard. After flying the thing for a while i realised that i almost never confuse left and right, it's almost always front and back.

Since flying a few different quads with different LED colour schemes i now think that a 2 colour scheme that shows the front and the back of the quad in different colours is the simplest and helps the most with orientation.

If you don't like red and green then red and blue works too; but if you fly around twilight when the sky is blue then green LEDs show up better.

Most people choose to put red at the back because it reminds them of car brake lights.

This is my HexaCopter. Everything built from scratch. Also the camera gimbal. The two are built for each other (literally).
Its constructed in Inventor 2012.

A video shot this saturday:
"Ved Jens" (8 min 49 sec)

This makes sense to me. I guess if you know which is front and back, then left and right is easy to figure out.

I'm also planning on adding something small top and bottom f the center plate since it will be easier to judge angle at a distance.

Disturbed, but in a good way.

Mine has all the same color lights on the arms. I just put a plate with a bunch of lights facing forward on the front of my centre plate. Its VERY obvious when it is facing you just like headlights.

I've got 2 small patches of a third colour on the bottom of my two stunt copters on the front arms - when they are the right way up i can see the third colour and when upside down i can't, which definitely helps with orientation at a distance.

well looks possible if the goal is to hang it in one spot for extremely long periods

I think perspectives for the multirotor copters are changing from sport (acrobatics) flying to a role of Observation.

To strive against the stream, here is my little funquad, 200mm M2M, ~100g without battery.

Cut from 2mm CF-sheet, asymetrical shape which helps a lot in terms of visibility in acrobatic flight. Equipped with 2000kv 10g motors, 6a plush esc with SimonK (the old ones when thex were still using atmega) , FrSky RX, 5x3 GF props and 3s 800mAh battery.

The flight controller is a small and compact box where pro mini, WMP with ITG3205 and RX where soldered and shrinked together.

Here is the Vid, make sure you watch it on Vimeo in HD:

Mini Multiwii Quadrocopter Funflying (6 min 36 sec)


To be honest, it is used for "observation" as well, check my other vids, there is a FPV-video, too ;-)

Helicopters and other flying platforms have always been used for observation, but the growing popularity has provided for a range of advancements that are bring the tech to the masses, tethers could represent a huge boost.

I could see a "cart" design that plugged into a standard news van system for on the spot reporting of breaking news. Long airtime, high current, and highspeed downlink allows for HD cameras and with some of the newer autonomous tech could be piloted into position by someone with limited training. No ladder, boom, or helicopter needed.
