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.

Hello together,
I bought a GAUI330xs 2 years ago and was quite happy with it.
Then, in October this year, I read an article about using an APM2.0 in a model airplane in the German magazine FMT.
This was so interesting, that I just ordered the APM 2.5 with an uBlox GPS and the EZL0 Sonar Sensor. This arrived in October and two days later, my old Gaui330 was airbone again with the APM.

Now I come to the point, what I really wanted to tell:
I want to thank all the members of the develompement team, the authors of the Wiki documentation and the very helpfull entries in the DIY Drones Forum.
Nearly all problems, which I had during setup, tuning parameters etc. I could solve with this extensive package of informations.
Today, the GAUI made at least 20 waypoint flights with a video cam and I have already that much trust in it, that we made flights without having real eye contact.
There was only one little crash during sitching to the Sonar Sensor. Without the Power filter and electrical noise shielding the data of the Sensor was a bit instable. Except above little trees and scrubs, it works fine today. Even automated landings are lookunig nearly professional.

So again many thanks to all of you and I'm looking foreward to upgrade the Robot, may be to an Octocopter with FPV and Telemetry.
The APM is in my opinion a far better product than some Japanese or Taiwan Systems wich are in price regions of mor the 1.000 USd in Europe.

With best regards, Roland.


Here is mine, far from complete but I will slowly get there.

propellers: Not decided yet - 10x45 or 11x3 to start with and later CF props

motor to motor distance: - 680mm

battery: Possibly 3S 5000mAh

Here's my latest APM2.5 equipped Quad. It is a Reptile500 Frame which is a TBS Discovery inspired design.

REPTILE500 Frame from Himodel.com
Motors - AX-2810Q-750KV - Hobbyking
Props - GemFan Carbon Nylon 11x4.7
ESCs - Hobbyking 30A UBEC SimonK'd from sgdrone.com
Flight Controller - APM2.5 (2.81 quad firmware) with Ublox GPS from sgdrone.com
Battery - HK 2200 Turnigy 20-30c Lipo
AUW - 1.4kg with GoPro

Since I'm using old batteries with many cycles in them, the flight time is estimated to be around 7-8 minutes, with new batteries, I reckon a flight time of close to 10 minutes.

I've got a more detailed overview at this link.

Here goes information about my quad.

First post...

I just picked up a 3DR Hex with the Ardupilot 2.5 Mega controller...  I've assembled it, but right now it's just sitting here by my computer.  I don't have a battery that will run it..  I'm waiting for a pair of 4S 35C 5000mAh batteries to make their way here from Asia. 

I upgraded the 3DR Hex package and went with the uBlox GPS card, and the 880 Kv motors with the 30A ESC's.   I'm hoping it will lift my Canon 7D DSLR.  The photo below shows it sitting on top of the DSLR...  I don't have any sort of camera mount as yet, but I plan to fab one up after I get the bird airborne..


Very nice build. Just a suggestion in case you haven't already but you may want to tie down your ESC's because if they are left to move around the connectors may become loose and you can loose power to a motor in flight.

Thanks..   The picture I attached was an early pre-test shot.  It was good that I didn't tie down the ESC's because one was bad right out of the box.  It got hot to the touch seconds after powering up and wouldn't turn any of the motors I attached it to..  The rest of the ESC's worked fine.   I'm still waiting for a replacement in the mail...  

Everything will be snug and tight before it takes flight :)

Hello everyone...

One of my first posts so I guess I'll introduce myself first.  My name is Andrew and I currently reside in the Daytona Beach, FL area.  I have been flying RC for many years and recently got into FPV with a skywalker X8 running a full Eagle Tree OSD/Diversity/Telemetry setup.


As I'm also into photography, I got interested in building a camera platform that would eventually be able to carry my Canon T4I.  


So this is what I came up with:


*S6 hex air frame from www.sto.org.tw

*S6-Pro Gimbal from www.sto.org.tw
*STO 530KV motors
*Generic 40A esc
*APM 2.5 with GPS, 3DR data radio and 3DR current sensor for flight control
*Paris Sirrus multiwii board for gimbal control
*DX8 and AR8000 TX/RX combo

*Turnigy Nano-Tech 4S2P  10000 MAh


I didn't find much info on STO but they had a lot of videos of their products and they seemed to be of pretty good quality.  I took the risk and ordered the air frame, motors and gimbal.  For the most part, I am happy.  I can see that I will probably have to modify the gimbal if I'm going to get truly professional results... It has a bit of slop that could be taken out with some better components.  I will probably upgrade the MultiWii controller as it doesn't seem to want to hold the horizon level no matter how much tweeking I do.  I learn something new every day tho so it might just be something I'm overlooking.  The MultiWii board leaves a little to be desired in the area of documentation (esp. documentation regarding using it as a stand alone 3 axis gimbal controller).  The pitch axis is locked in pretty well, but with the roll axis the servo keeps up fine but when it settles the mount isn't level.  For example: from a level position roll the gimbal 5 degrees, the servo tracks fine with proper speed but when they stop the gimbal settles at say 4 degrees.  I'm not sure what to do to improve this.  Overall, im pretty happy with it but I havent started messing around with the yaw axis or added manual control to the system.  So we shall see...

The only other gripe I have about this setup is the motors from STO.  They only have a single grub screw securing the bell to the shaft.  After just one tip over, the grub screw on both front motors stripped so now the props slip a little.  This is evident in the copter always wanting to be in forward motion.  I'm guessing this is due to less power being transferred to the front two motors because of the slip.  I ordered a set of bolt on prop shafts that will hopefully alleviate this problem.  In the mean time, I just tuned up the APM for a good, stabilized hover.  This was very easy and required very little tweaking.  It flew almost perfect right out of the box (See the first video)...


Anyway, thanks for reading and if anyone has any tips I'm all ears!



Really boring video of me hovering.  Hopefully I'll have something better soon.
