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.

To try to give you an idea of how much weight you can save by building your own design, I'll give the following as a reference.  It's for an Octa V, so it has 33% more weight than a Hexa.  No camera stuff yet or FPV.  Just APM, telemetry, and external GPS.

  • 330g Structure/platform
  • 399g Electronics (mostly savings in using the right gauge wire)
  • 729g Motors/Props/Mounts

From dealing with commercial products, it's relatively easy to eliminate 450 grams if you build it yourself.  If you are interested in trying it, the best build-to-remove-weight feed on this is:

Oh believe me, I know all about the weight advantages of building my own frame.  Especially with access to the proper materials :)

I'm sure there's more projects in my future and I will definitely be building my own frames.  The goals with my hex were to focus on other aspects, namely programming.  I won't have as easy access to the shop this summer so it was quicker to just buy a frame and get to work.

Thanks for the link to your article.  I've read it before but had it stashed away in the back of my mind :)

Possibly in the fall I'll get time to design and build a new frame using some aerospace composites.  The nice part is that drones are small compared to what I use at work, so I can just use the scrap bits of material!

Did you connect the RCTimer gimbal to the gimbal outputs on the APM controller, or did you purchase the external controller board that RCTimer sells for the gimbal.  ??

I'm looking at the RCTimer gimbal, but I'd like to know if it can be directly connected to the gimbal pins (10 & 11) on the APM2.5.

You can not connect the gimbal directly to the APM's output pins.  A10 and A11 are for servos only, not brushless motors (technically you shouldn't even power servos directly from the APM).  You'll need the brushless control board.  I have the RCTimer one (Martinez-based, I think?) and it works fine.

You might be able to connect just the signal wires from the APM to the gimbal controller (bypassing the controller's IMU) but I'm not sure why you'd bother.  Seems to add more complexity for very little gain.

If you have any questions about the RCTimer gimbal, I highly recommend reading this thread on RC Groups:

http://www.rcgroups.com/forums/showthread.php?t=1856876

Any possible question has been asked and answered in that thread.

Perfect..  That's exactly what I wanted to know.    Thanks!

I had similar landing skids like you do. They catch a lot of wind! Is it going to be a quad, hex or octo?

I'm starting to live your story :P here in Portugal i have lots of problems in finding parts and electronics! And i was not a programer in my 20's i'll just have to excell myself in the design, since i'm an architect and an artist. But i'm starting to feel that i love quadcopters, not so much the hex or the octo!  Keep improving and if you dont mind share the rctimer tuning process, i them too.

Hugs

Tiago Santos
