Pro Flight time
The 3DR Solo can fly up to 20 minutes or 15 minutes with payload (camera)
It packs some good range, 6 miles (9.5km). Makes it suitable for almost anything you want to do with it.
Pro Really fast
It is really fast, the maximum that the Solo can do is 55 mph (89 km/h). Made possible by its design and four 880 kV motors.
Portable, weighting in 3.3 lbs. (1.5 kg) or 3.9 lbs. (1.8 kg) with GoPro® and Solo Gimbal.
Con Frequency of operation
Operates on 2.4GHz frequency, which is not ideal for drones if you fly it in a city where there is a lot of interference. Normal wifi networks use the 2.4GHz so interference occurs where there are many wifi networks.
Con GPS problems
Users have reported that they had GPS problems. The GPS problem is likely due to the positioning of the module. Instead of having a small mast on top of the drone for GPS and dual GPS modules (One for US satellites and the other for Russian satellites) the single GPS is located under the battery, blocking signals from some angles
Con Stability problems
Other users have reported that the drone may drift away even if you hit the stop button. This appears to be linked with the GPS problem
Con DOESN'T COME WITH A GIMBAL OR CAMERA
The basic pack of the drone doesn't come with a camera or gimbal. The one i linked comes with the gimbal and you need to provide the GoPro.
