Hi everyone,

I'm creating this thread to share your drone/copter information. I believe, this would help immensely for newbies like me during the initial build. For example, the Chris's blog on cheap Hobby King quad configuration is really a good resource.  

I don't want to burden anyone who is willing to share their info. Hence all fields are optional. Atleast the first 5 fields are ideal. Please find the list of fields to copy/paste at the end, so you can start filling :-). 

Here goes information about my quad.

That is a very impressive hexa. That 20 min flight time is superb for an amateur multicopter.

I have a few questions:
How heavy is your hexa including the two batteries?
Do you know how much payload capacity it has?
Also, do you happen to know around how much thrust each motor puts out at full power?

I'm trying to build a quadcopter for FPV with a decent flight time. I'm aiming for 15min+
Thank You

I haven't posted here often, but I thought it would be fun to share info on my quad.  First, the obligatory:

frame: My own quad frame + electronics enclosure.

controller/autopilot: APM1

motors: 880kv

esc: 18A (Turnigy Basic)

propellers: 10x4.7

battery:  3S 4000mAh

flying time: ~9Min

weight: 4.1 lbs

radio: Hitec Aurora

video/osd: GoPro, minimosd, 5.8Ghz Fatshark transmitter, Fatshark dominator goggles (All removed in the most recent pictures for basic testing)

other: Sonar, Xbee, GPS/Mag  (All removed in the most recent pictures for basic testing)

Front picture (that is a custom go-pro mount hanging from the front)

Rear:  Notice the sonar.



The arms and core structure (which fastens the arms) were milled out of 6061 alum.  After destroying several other frames, I wanted something sturdy that I could learn on.  This most recent one has survived 20+ *very* hard landings without issue.  

The electronics enclosure is the fourth enclosure, but only the third printed variation.  It holds the receiver, apm1, and gps.  The top is laser cut (so that I can see LEDs easily).  The holes that you see are there for fastening the xbee and video transmitter to the top.  I need a good enclosure for those, but haven't undertaken that yet.

The battery + sonar mount is PLA printed on my reprap.  After having an incident where the batter slipped out of the velcro straps in flight, this one has a 6mm lip that holds the battery from shifting while the velcro holds it snug.  There is a box that holds and protects the sonar itself from damage which is attached to the sonar mount.

The gopro mount is printed PLA as well.  It holds the go-pro very well and you can see in the videos how vibration free/smooth the it is.

All of the parts were designed in cad programs and milled/printed/lasercut on CNC machines.  I'm very pleased with the result.  If anyone would like to see some pictures of the previous frames, enclosures, or process I'd be happy to share in a reply.  See the video links below (and excuse the beginner flying).

You can visit my profile for some pics of a few of my quad designs. Didn't want to put too much on a post. So far they have all shared the same gear and weight range, or close enough. Designs are with sport flying in mind, being able to roll and flip. Although the thrust/weight should offer a decent payload, no tests or design accomidations have been made.

I have an APM2 on order and am looking forward to getting the latest version quad to maiden on my new controller!!!

more about specific versions here as well.


frame: my own designs

controller/autopilot: KK v5.5 (different "brands")

motors: eMax GT 2205 -1660kv

esc: Hobbywing 12A

propellers: 8 x4.3 SF

battery: 1800 2s 30c or 1800 3s 30c

weight: 14-16.5oz depending on frame and cell count

flying time: 14-18min depends on stunts or just flying



Can you give the weight sizing as well?  Thank.

That is a good idea, let me add it to the original post.

frame:  Personal monstrous design.  3/4 Aluminum tubing
controller/autopilot:  APM2
esc:  Turnigy Plush 60A
motors:  E-Flite Power 32 770kV
propellers:  APC 13x4 Electric
motor to motor distance: 36 inches

battery:  Turnigy 20-30C 4S 5000 mAh
total weight: ~8 lbs
flying time:  Wouldn't know.  Can't fly it for more than 30 secs before crashing

radio:  E-Flite LP5DSM

other:  Lots of Zip-Ties that seem to come off at the wrong times

Misc (hacks/mods):  Carefully crafted StarBucks Directional Indicator


I think I may have built this thing waaaay too big and heavy.  Can't seem to tune the PID to keep it steady.  Constantly have to fight it to keep it somewhat leveled, otherwise it draws blood.  Anyone have any ideas?

You might want to try two things to improve handling:
-Move the ESCs further away from the APM. They might give you some sensor interference in flight.
-Mount the APM directly to the frame, with Velcro or nylon stand-offs. It looks like the suspended mount might give you more vibration instead of dampening them.

Thanks Knut.  I have put the ESC's about half way on the arm.  Once more props arrive, I'll try that out.

If that doesn't, I work will try putting the APM2 on a more solid platform.

Here goes information about my octo.

Frame: Carbon Fiber Custom frame

Controller/autopilot: APM1

Esc: Redbrick 70A with simon FW (http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=...)

Motors: Turnigy L5055 400Kv (http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=...)

(Maybe a wrong selection, I don't know yet)

Propellers: 13x45 Slowfly Mikrocopter

Motor to motor distance: 100 CM

battery:  Turnigy 6S 5000mAh

total weight: -- Kg

flying time: Don't fly yet

Radio: Futaba FF9

Video/osd: Custom Camera Gimbal

Other: Sonar, 3DR Radio, GPS/Mag, Attopilot current sensor


Any suggestions or opinions?


Really Cool!

Wouldn't you need bigger propellers though?
