Spare propeller screws/bolts?

Does anyone know where to buy spare bolts for the propellers? I broke the screw shaft on one. It doesn't look like APC ships propellers with these bolts.ThanksContinue

I'm not so interested in building the multirotor copter to fly it manually with an RC controller. My interest is in programming it. Ideally using an XBee, or other non-RF communications, I'd like…Continue

Jimmy Thostenson replied to Lee's discussion Maple Seed UAV"Waaaaaaaay, novel! I wonder how precise everything is mounted since the design relies extensively on a strictly held center of rotation. I am also curious to know how they program the banking, yawing, climbing, etc. to work independently of…"

jazztech replied to Lee's discussion Batteries - Extended Flight Time"Lots of interesting infos on this rcgroups thread : 51min in the air
From my experience, good efficiency require big props turning at a slow pace. That's why Trad Helis are more energy efficient than multirotors, even with losses induced by…"
Lee replied to Lee's discussion Batteries - Extended Flight Time"I appreciate the info emile. I have some research to do on power supplies :)"
emile replied to Lee's discussion Batteries - Extended Flight Time"You cannot use 6s lipos. Even 4s could be a little too much for those motors.
Regarding the video you should pay attention to the specs:
2 x 11000 4s batteries @ 820g each!
14x4" props
and 530kV motors.....
there is almost 1.7Kg only…"
Jean-Marc Gendreau replied to Lee's discussion Batteries - Extended Flight Time"If you are using standard 3DR or JDrones ESCs and motors, you can't use a 6-cell battery pack. The voltage would be out of specs. Use 3 cells or 4 cells battery packs only."

Lee replied to Lee's discussion Motor and Prop Assembly for 3D Robotics Hexa?"@Martin Thanks for the info about reaming the spacer. I did have to drill out the holes on the arms to make room for the "e" clip. I haven't run the motors on a servo tester yet, but they did appear to spin freely by…"

"Hello Lee,
The grey ring should sit down over the non-threaded part on the prop adaptor, the ring is used as an insert into the prop itself, this takes up any play on the shaft, there normally is a number of adaptors supplier with props to fit all…"
Michael Krader replied to Lee's discussion Motor and Prop Assembly for 3D Robotics Hexa?"the step locates the prop. when i switched to the ones i found its so much better. sometimes the spacer can cause probs. one less thing to worry about."
