The DroningON review of the new KingKong 90GT Brushless Micro FPV Racer.

KingKong 90GT Brushless Unboxing, Binding & Flight Test Review

The first micro brushless that we reviewed from KingKong was good, the Q90 impressed us as an entry-level mini FPV racer, but the new model, the 90GT is even better. We have now added our Part 2 Flight Test video, see below and enjoy!

Despite the slightly clunky design of the earlier KingKong Q90 model, it flew well and was pretty crash resistant, but the specification lacked elements which have since become the ‘norm’ on such FPV racers.

KingKong have since launched the new 90GT which is a far superior quad, with slim-line design, 4-in-1 ESC (speed controller) board which even runs BLHeli.  At 10g lighter than its predecessor it is also quicker and more agile.

KingKong 90GT ESC Calibration…

A few drone-fans have mentioned that they have had issues with the motors on KingKong 90GT, the symptoms include flipping when trying to take off and general instability.

There is a simple cure which should be performed even if you are not experiencing issues, as it will ensure that your motors and speed controllers are synchronised. This procedure is also shown within our Part 1 review video.

  1. Ensure that the battery is not connected to the quadcopter.
  2. Connect the USB from the flight controller to BetaFlight.
  3. Head to the ‘Motors’ tab and check the warning checkbox, now slide the ‘Master’ slider up to maximum throttle.
  4. Plug the battery into the quadcopter (don’t worry, the motors won’t fire up) and wait for the beeping to stop.
  5. Now slide the slider to its lowest setting and wait for the beeping to stop.
  6. Disconnect the battery and quadcopter from the USB cable.

And that’s it, the above steps will calibrate the quadcopter which can improve performance and stability.
