in a quest for weight reduction
its now key to remove unnecessary bits and pieces from a quad frame that is just to overly complex
if anyone remember my last post of
http://diydrones.com/profiles/blogs/flight-of-the-external-hdd
the 2kg AUW
its like putting a multirotor on a weight loss program in some sense.
this call for a complete design change.
size 450
AUW 1.35Kg
frame only 410g
the only screws/bolts used are the ones holding the motors in. the rest of the frame is one solid piece
landing gear clearance is enough to put a small camera under
nice hard shell contains electronics and battery sits on the upper deck.
at least I don't have to worry about a few loose screws on the frame.
just update video
no problem at all , its even more stable with this layout. the arms act like leaf-springs dampening vibrations

pics as posted , should there be enough interest this, would plan to produce some.
Very cool, Cliff...any chance of more detailed photos or maybe even a drawing? Thanks! Stan
Rjc: not bad with yours too. it just needs a bit more power thought.
Wow! looking good CliffN! I like the idea of your landing gear..
Jay: its a Light Tank in comparison to Reggie's design
maiden flight video will soon follow .
no problem angle bars are not necessary . the aluminum used is difficult to bend in the first place so its pointless to do so and the flex is minimal along the whole span plus I needed leaf-springs to reduce vibration anyway , the AUW is just 1.35Kg nearly comparable to CF frame of its class size.
this design relies heavily on the material strength. than of form thus the name simplistic uni-frame
I think I would have angled the bars that connect to where the motor is mounted.. flat aluminum like that seems like it would flex a lot where just mounting the bars at a angle or up and down instead of side to side would help. Pretty cool frame... does it fly well? what does the vibrations look like with those flat bars ?
that's nice frame CliffN!
