Couple comments/questions
I think the controller is about perfect on the P3. Weight is ideal for me and really like the button layout.
Well I think you only gain a little with the Solo/GoPro I think it will only randomly shoot pictures while you are doing video. You don't get to push the shutter button on when.
What do you mean? USB connection to device. I have not heard of anyone having issues with connection.
I am having a hard time figuring out your needs. Seems like you want the best of the best but are happy flying a blade which even with the GoPro mod you made has to be considerably substandard to the P3.
But there is no excusing the poor service you have received.
I hear you, I do want the best of the best.. after spending almost $2300.00! And I really thought the Solo was the one... I felt the P3 controller with my Nexus 7 tablet on it was very heavy. The solo controller is much lighter than the P3. Once connected to the app and got the live view, I had like one "bar" and lost connection ( plugged in to the Nexus 7 ) happned a couple of times, no big deal. As far as the shooting of pics "while " u video at the same time the Solo will do this once you get their Gimbal! P3 was NOT capable of doing this at all , ( which was important to me ) So yes the Blade is kind of old school now but it works flawlessly compared to all the Solo and after reading all the problems here on this forum I am happy its not JUST me.. The people at 3DR should of staffed their phone lines better and had more replacement Solos to give out when they sent you DEAD ones! Simple 2 things to do when you are putting out a new product! JMO
