    James F.,

    Oh yeah forget to say. If you think that you have something to offer for this ArduCopter project, please contact me or Chris and we can look things more... My contact info is on title area and Chris's info you can find on bottom of this page on gray area :)

    Yes we have. Problem with rubber spacers between bars is that it create movement on bars and that way affects gyro/accelerometer calculations. We are even measuring vibrations from different aluminum and other materials along with shapes of them.

    Also now that whole ArduCopter is based on gyros of "new technology", we going to have a lot better resistance against vibrations and harmonic frequencies on our frame.

    For hobbyist who build their own frames we naturally cannot guarantee all this measurements. And like all other projects too, we are developing this step by step.

    Here goes a render with the spacers correction. Isn't the final look. When we finalize all modeling job of the pieces, then we can concentrate on doing some tests with different materials and color, by the Jani's orientation. For now, the object's finishing are the most simple as possible, for not losing the focus. First of all, we need all objects done, to test and find the better way to accommodate all parts. You will certainly be surprised by the great job that our team is doing.

    Design is rather varsatile, ESC can be mounted both ways on top/below center frame and also to the booms. I personaly don't want to mount them on booms close to the motors due high risk of destroying ESC on a crash. Also if you mount them close to the motors, you will add extra weight that needs to be turned and we all know that weight at end of long arms it never good, this wastes also a lot more mAh's turning multirotor. On booms close to center frame is better plase.

    But user can deside it while they build their multirotors.

    @Ravi, Thank you but we already have partners for producing all needed parts and a bit more.. :)

    Hopefully DIY members get first dibs on the first batch.. Really like the simplicity of the design... Is the plan for the ESC's to reside inside the booms? ... if so, does it make sense to add ventilation holes/slits?

    That looks very good. What about camera mountings as an optional extra? Surely some users would like to use it for Aerial Photography.

    @Ron: That was what the original AeroQuad design used, but it's too expensive for our price target. We're going to custom manufacture arms that are better and cheaper for this purpose.

    What about using off-the-shelf Heli tail booms for the motor booms? I've always thought the square Al tubing might be excessively heavy on a quadcopter. Just a thought...maybe it would not be durable enough?

    We are trying to keep it as simple as possible and easy to manufacture and that way keep cost of the frame as low as possible but without doing bargain on quality. In future we might come up with really high end frames.

    Flex is always a bit problem due material thickens has to be rather low. And if we need to add some extra blocks to middle it means that we need to add also some extra screws which again means extra weight and that is something that we do not want :)
