Drone review from programmers point of view

Postive
- The frameworks are great, many functions can be easily controlled for Java (the language that I have used with us.
- There are acceptable for Android simulators that can mimic the flight behavior.
- Easily connected to existing software, are also REST clients.
- Setup done very quickly
- Price / quality OK, but keep in mind that several batteries and also a second indoor envelope needs to be purchased to work best sense to. For real presentations then another charger.

Negative
- The battery is incredibly weak. We bought for demonstrating equal to 4, otherwise you would have to 1-screenings again make an hour of rest.
- The drone
- Commands take a long time to execute. (Start command min. 5 seconds to execution)
- Indoor shell of polystyrene very easy beschädigbar, then of course affected flight behavior. Once ungücklich in the door edge and the fun may be over quickly
- Indoor deviation of simple launching and landing can be 50 cm, only moderately suitable for project status (in an emergency cord tie)
- Very noisy, so take in the company's own space, or develop home. But that may be me that occurs from a lack of previous experience only as drones.
- Resolution of the front camera is very low (is designed for video, but in my opinion this is a worthy point improvement)

Tips
- First Exception Handling integrate, as several had painful experiences that made the drone floating around uncontrollably.
- Come into the rotor with your finger stops it hurts but nothing from a tear. Reason that I know see a line above ... In between, I've got a fishing net ready laid for me.

Price performance is OK. Although happen many negative points in my list I want to emphasize that I have things like fun, ease of use, existing software (the mobile client are great and easy to optimally control) not mentioned. I have now written purely from my professional experience with it. For ordinary users, these points are partly of issues (eg deviation Start -. Landing command) - hence 4 stars because this product is actually a consumer product and I would love to fly with private now the drone. In my opinion, however, it is important to see the professional use, are probably even companies who would like to use a drone to spice up their booths at fairs. Here I would give 3 1/2 points, but must confess that my present in the same price range alternatives are known only by reviews.
