4 Channel PicooZ : Micro Stunts
 
Its realy fun testing the limits of a 10 gram 4Ch helicopter in your house. And here she is with a couple of videos on some of the stunts;

here is a more challenging task, passing through a 'smaller' opening;

here is the final leg of the sub micro 4 channel stunts. The heli is getting over exposed already on youtube :D. But i did finally add a "body" into to it. :)

This time its a test of the aileron response, that is flying "sideways" plus a little spot landing at the end;

Sideways through the loop and back;

And then through a smaller loop while still flying sideways;

And a quick "spot landing" on a small platform;

Thats too cool EQMOD. do you have some more close ups of how you did it?

I am using the "slide pin" approach as the mechanics is pretty much simple than using commutators, floating magnets, cyclic motors, etc. etc.

http://i263.photobucket.com/albums/i...cyclic_00a.jpg

One thing the delayed the completion of the project is the late arrival of this;

http://i263.photobucket.com/albums/i...co_4ch_001.jpg

Its the 2nd magnetic actuator which i will use for the aileron channel.
To complete the circuit, i added a 2nd walkera 4#3 servo controller board that will drive the aileron magnetic actuator. Here she is with the trim pot added. I used thin wires to make it light.

Adding the rest of the wires that will connect this controller to the aileron channel of the 4#3 2.4Ghz 4-in-1

http://i263.photobucket.com/albums/i...co_4ch_003.jpg

Now for the slide pin, instead of metal, i used thin hard plastics. Specifically a tail fin from an X-twin plane;

Using a knife cutter, i made two "plastic slide pins" for the aileron and elevator channel. I used a thin solid copper wire as poles so that i could easily bend them when the time comes in "fine-tuning" the cyclics;

and here she is with the 2nd magnetic actuator, 2nd servo controller and the two plastic slide pins mounted on the picooZ frame;

Close up of the cyclic mechanics from the front;

and close up of the cyclic mechanics from the rear. Take note of the two overlapping plastic pins;


http://i263.photobucket.com/albums/i...co_4ch_008.jpg


To keep the cyclic controls precise, i added centering magnets at the side of the actuators;

and here is a tracking test video;

and its maiden tail-in hover video;
