BOLT: Very small, fast + agile Y6 hexacopter

Posted by W. Thielicke on May 18, 2011 at 11:40pm



Once in a while a need a new copter, this time it had to be a very small Y6 copter. It is meant for FPV flying, and that really works very good! It fits through really small holes, and it flies very precisely. It is my first Y6, and I am pretty much convinced by this concept. Ok, well, flight time is an issue.. I get 6:30 min with 1000mAh, but that is still reasonable for such an aerodynamic disaster.

    @michel - It looks like the props are "Air Ace Propeller Set (L&R)" Part No. 5504955

    Where do you buy those I²C->PWM micro converters ?
    I developed them myself and I still have some PCBs here.
    why not the 3 of each side in the same direction and both side in opposite direction?
    well i think that would also work fine. Every combination will have its advantages.

    I have some basic questions ( I am currently not in tri-quad copters at all ). how do you rotate around the vertical axis of the copter. it seems that you have 2 props turning in one direction and the third one turning in the other direction on both sides( I assume to compensate for the gyroscopic effect) . why not the 3 of each side in the same direction and both side in opposite direction?

    thanks a lot mr.W.Where do you buy those I²C->PWM micro converters ?

    W.T

    Can you confurm the thickness of carbon fibre sheet you use?

    Thanks

    Incidentally, where do you source adxrs 610's?
    Well I borrowed them from another copter that I didn't use at that moment... Now I buy ADXRS620 breakout boards at watterott.com

    Would a two blade not be more efficient?
    Yes it would be more efficient I think, but I don't know of any 2-blade props (CW+CCW) that would fit my motors.
    Looking forward to see the next good copter and movie - until then you have a small gift in a donation box :-)
    Thank you very much! That will be invested in two gyroscopes for a stand-alone roll/ pitch compensated GoPro mount that I am developing at the moment :-D

    Do you have any kind of active altitude feedback?
    No, at the moment that is just the ground effect, which is very prominent for this type of copter. But I am working on a five IR distance sensors that hopefully stabilize the position of the copter with respect to walls and the ground.
