Finally some useful guidance! Hardcore 3dr supporters should be ready to embrace clones. The broader the support base the more secure 3dr will be. Ask yourselves have clones harmed or been a benefit to Intel and Microsoft? Bare in mind that in an open community support is a two way effort. Just because I've ordered an Arduflyer does not mean I'm boycotting all or any products available through the DIY Store. Thus support for further development by 3dr remains intact even though I'm trying something slightly different.

However if the DIY community closes ranks and 3dr locks down their products, like Apple corp, I will abandon DIY and support some other truely open source efforts. The old addage, "You attract more flies with honey..." was never truer.

Another difference between the ArduFlyer and the APM 2.5 seems to be in the mystery port which connects to the power module.  Using the 3DR power module with the ArduFlyer it only gets about 4.7V to the board.  Using APM2.5 gets the expected 5V.  Calibration and voltage/current detection seems to be a bit off as well due to that, but I haven't played with it extensively yet.

Thieves of R&D with forum sock puppets posting on the original's forum. Welcome to the modern world.

they call it smart business... survival of the fittest. LOL

if you are good in R&D you should be smart enough to protect your investment as well ... :)

take it with a pinch of salt buddy.... it happens...

You are very correct that you need to protect your investment, especially from the biggest thieves in the world. This is why all major technology corporations have counter-intelligence branches now... thank you China (and a few others). 

Yes, you can take it with a grain of salt and accept it as daily business because it will always happen, but don't excuse it as an appropriate practice.

"Call it whatever you want if it makes you feel better but the bottom line is, it is stealing." 

Lets examine the Creative Commons licensing together shal we? 

The license that ArduPilot gear falls under

http://creativecommons.org/licenses/by-sa/3.0/

The license that 3drobotics perhaps *wants* the ArduPilot gear to fall under

http://creativecommons.org/licenses/by-nc-sa/3.0/

The key lays in the two little letters N and C - "Noncommercial — You may not use this work for commercial purposes." 

Now lets go and browse the Eagle Files - http://stuff.storediydrones.com/APM_v252_RELEASE.zip

(not to mention they are usually *broken* outdated Eagle files, to help prevent cloning in the first place) Please note the words "Released under the Creative Commons Attribution Share Alike 3.0 license"

What do you do when you offer your work under CC but you don't like the way someone uses your work? http://wiki.creativecommons.org/Frequently_Asked_Questions#What_can...

 

3Dr made their bed when they picked CC-BY-SA... they should lay in it until they change to CC-BY-SA-NC. It really is that simple. 

I really encourage you to read the Creative Commons mailing list http://lists.ibiblio.org/pipermail/cc-community/ and search for the word "stealing". You'll likely run across this thread http://lists.ibiblio.org/pipermail/cc-community/2010-November/00573... it is a fun one!

Looks like I trolled the troll:)

lol if your goal was to help folks get a better understanding of Creative Commons licensing then hats off to you sir. Jolly good show. ;) #TrollAchievementUnlocked.

I'll give it to you though, you bring up some good points which pertain specifically to this case.

Thx for this! So to sum it up: In refusing to answer clone questions or at least obfuscating, confusing and alarming by using vailed language, 3dr violates the spirit of SA component of the CC license. I would say that in light of DS's excellent post this thread is pretty much done.

You keep bringing up the licensing that the ardupilot is made under, and you say that 3DR "perhaps" wants it to fall under another.

The thing is, no one from 3DR is complaining. Your just assuming they feel a certain way and are running with it, but all evidence suggests that they are perfectly happy with the way things are. As long as they keep innovating, they don't have a problem.

Likewise they don't have a problem "...if they only clone the products and sell them at lower prices, that’s okay, too" - http://www.adafruit.com/blog/2011/05/19/cloned-open-source-hardware...

come on man... everyone knows you don't have to *complain* directly about licensing when you can send a takedown notice or simply shun both vendors and users of clones alike. ;)
