"Hi Thanh, I think it is not such a good idea to use props that differ in any way, in pitch or diameter on the same copter. Although the APM code can probably make some allowance for that, it is optimized to treat all motors / props the same, so it…"

But there is a Huge - Seemingly Intractable Problem. At least in my estimation of things:

No the Iris isn't the problem, It's a really great 3DR copter, probably the best one available for the…

This copter has a lot of things right and is really a study in design excellence.

Hola que tal Gary sabes el hadware que necesito para hacer mi drone Cooperativo

Hi Gary,

Just a thing on shipping rates (from your comment). I was also mad because of high shipping. I sent support an email and they shipped the parts for free through standard mail! I got it in 2 days ( I live on the east coast). There is a size limit though, can't go above 13 oz, but for small parts its fine. Oh and btw, when you email them, ask for Lorena, it may take a day or 2 more because of her work hours, but she's been amazing with shipping like this.

 

Sorry this is the only way I could contact you!

 

Michael
