New 90GT and GB90 Sub-100mm FPV Racers With Brushless Motors at GearBest

There was once a time when all sub-100mm FPV racers came with brushed motors. They were inexpensive to purchase but the brushed motors left much to be desired. Now things are getting a lot more exciting in the sub-100mm segment especially for Tiny Whoop fans now that some manufacturers have started introducing micro FPV racers with more powerful and durable brushless motors.

Two such models are the KingKong 90GT and GB90 which are now available at GearBest. Both are powered by the popular F3 flight controller. Let’s take a look first at the KingKong 90GT.

KingKong 90GT
  • Diagonal size: 90mm
  • F3 flight controller (6DOF)
  • 4-in-1 BLHeli-S 3A integrated ESCs
  • 1103 7800kV brushless motors
  • 3-blade propellers
  • 7.4V 370mAh 2S battery
  • Built-in 5.8G FPV camera (800TVL / 150 degrees FOV)
  • 16-channel / 25mW video transmitter

The 90GT features an open carbon fiber frame and a supplied surround prop-guard that is similar to what you’d get from toy drones such as the Syma X11. Due to its tiny size, the designers have chosen to equip it with an integrated 4-in-1 ESC to make changing ESCs easier. Imagine trying to replace a damaged micro ESC on a tiny drone such as this and you’ll understand why they decided to go the integrated way.

The 90GT weighs only 42.9g (without battery) and is small enough to fit into the palm of your hand. It is currently available in three versions — with FrSky receiver, with DSM2 receiver and without receiver. All three versions cost $130.90 and do not include a transmitter.

  • Diagonal size: 90mm
  • F3 flight controller (6DOF)
  • LittleBee 12A Opto Pro ESCs
  • 4000kV brushless motors
  • 2-blade propellers
  • 11.1V 500mAh 3S battery (recommended)
  • Built-in FX798T 5.8G FPV camera (600TVL) with cloverleaf antenna
  • 40-channel (including RaceBand) / 25mW video transmitter

Unlike the 90GT, the GB90 is available only in PNP (Plug and Play) form which means it doesn’t come with a transmitter, receiver and battery. The GB90 also features a carbon fiber frame with integrated prop guards that cannot be removed and separate 12A LittleBee ESCs for each brushless motor.

The GB90 is available for $187.84 at GearBest.
