Comparing the Matrice 200 Series and the Matrice 300 RTK 

Where is your shop?....can I use my smart controller with the 300?....I have original smart controller not the enterprise

how much it cost the whole setup. matrice 300 rtk + 2 extra battry + h20T

Can you mount a camera on the top of it?

Who offers the radar payload? I heard it mentioned here aswell as during one of the dji webinars but cant find any info on it.

any suggestions on the SD memory cards - size - speed - brand?

How much does the M300 cost? It is strange/shady that no one lists the price on their Websites.

Honestly the M300 arms aren't that difficult to unfold. Just do the Forwards arms first, then the back arms!
