Tricopter chassis v0.3
After a month-long hiatus after the crash, I redesigned the tricopter chassis.
The aluminum arms are now foldable, and the motors are closer to the center of the chassis (I have yet to trim the arms to a shorter length). There is room for the new and bigger ESCs underneath the other electronics.
The Seeeduino/protoboard/sensor blob is bolted to a wooden plate, which, in turn, is attached to the center piece with bolts isolated by rubber grommets. This, combined with a rigid mounting of the battery to the center piece, seems to work much better than foam in isolating the sensors from vibration.
Total weight of the machine, with battery, is 2050 grams.
