That a nice custom Arducopter build!, Looking forward to seeing some videos of it in the air!

You are the man Matt another cracking build. Right result today as well. I suspect you may be having a beer.

ok, so it is just another example of what I like in your build, a little detail that does not speak for all the things I like... but I never considered using an i2c connector-to-pins adaptor like you have for the magnetometer. I think I am gong to adopt that going forward for all my compasses. I always use an i2c splitter, because I am doing other things with the i2c bus, but by soldering the cable directly to the board, I have a fixed i2c cable length, and cannot swap magnetometers between all aircraft. Thanks for the photo!!

What about autonomy / efficiency ? 5kg with this small 54gr motor .... hmmm

my octo with similar motor have a poor efficiency.

@ gary - thanks for that, and yes great win, just france stands in our way......

@ eduardo -  simple maths and 4S lipos , a standard RCtimer on motor on 4S and a 10 by 4.5 prop is good for 1300 grams thrust, multiplied by 8 is 10.4 kg thrust. these microdans are special, large diameter stator and better cooling than an average motor allows them to work well beyond their size (I have a 2510 microdan 2100 kv motor that sits at 700 watts in a flying wing, and a 38 gram one that handles 350 watts) www.gobrushless.com

 

@mike - thanks :)

 

@UT - nice way to post a link to your shop :)

Microdans rock, I have one on a wing

Comment by Mathew Wellington on October 16, 2011 at 10:08pm

only one ? i have lots of microdan flavours - guessing you run a 2345 kv ? bent 1 shaft in 2 years of super hard flying

 

Ardu has come along way,impressed with how everything came together,sonar/mag/gps and telemetry all  worked out of the box
