When I ordered the Pixhawk on Wednesday, it was out of stock. I called 3DR and they informed me that they expected new ones by the end of the week. I just received the email saying it had shipped. I’m happy with that!
I’ve also sent two questions into support since Wednesday and had responses the same day to both my questions.
So far I’m really impressed with the support from 3DR.
I wasn’t impressed when I found out that the Power Module for the Pixhawk would only support up to 6S batteries and they had no intention to update this anytime soon.
Thankfully you can purchase third party versions on Amazon that support up 7S batteries.
