I suffered, choosing between the base and the Combo set, and in the end I chose the Combo. This is the right choice - a handy bag and everything you need to work outside where there are electrical outlets. The software is up and running correctly on Blackberry DTEK 60. Pros: Combination of characteristics close to the Phantom, with a very compact size when folded. If you need a device to shoot on large enough ranges, combined with the mobility of the device, then this is what you need. Significantly more stable than Spark in gusty wind conditions. Has cons: The main disadvantage for all DJI products, and more specifically for the DJI Go 4 application, is to marry the quadcopter and phone. In short, this is a scribe . Outcome is this: 1. Samsung - either a blinking default usage confirmation window, and a mustache (Tab s2), or a reboot on S7. 2. Nexus - freezing during the flight. 3. HTC one 10 - does not connect and that's it . But the remote control turns out an excellent charge . for a mobile phone . And suddenly! I got married with a Blackberry DTEK 60, but even here the length of the standard USB type-C cable is not enough to reach the connector on the phone. For a product at this price, this is a shame! So get ready - when buying a DJI product, you will have to enjoy the exciting process of finding a gadget that can pull the load and marry the program. And this, to be honest, + 20-40 tyrov to the price of the device.
