While there are attempts being made to push the size limit of quadcopter to the maximum, the community of micro and nano drones is only getting bigger. With micro indoor FPV quadcopters being the flavour of the season, there are quite a lot of options to choose from. But if you’re a beginner and prefer building your own, choosing BNF versions is a good start. The GB104 X4 micro indoor FPV drone that’s on sale now is one such drone that’s extremely small and weighs just 37 grams.
The GB104 X4 features a 650 TVL camera for FPV. The video is streamed by a 5.8 GHz 16-channel 200mW FPV transmitter, thereby giving it a greater video range than typical brushed indoor FPV quads that offer 25mW VTX. Users can adjust the camera angle in three levels manually if required. The camera has a very usable 170-degree field of view as well. The FPV transmission range is between 500 to 800m depending on the flying conditions.
The drone has a carbon fibre base frame to add to its strength. The Naze32 flight controller sits firmly on top of this frame. While the exact version of the Naze32 hasn’t been specified, we believe its the basic 6 DOF one being used here. The drone is compatible with DSM2 remote controllers and the receiver is shipped with the drone.
The motors used are the 8520 brushed type, the ESCs to drive them are embedded on the board. You can, however, swap the receiver for another one (say, for example, a micro Flysky receiver).
GB104 X4 Indoor FPV Quad: Pricing
The drone is compatible with 1S 3.7V Li-Po batteries, none which sadly are included in the BNF package. A typical 700mAh battery can keep the drone flying for roughly 4 to 8 minutes. If the GB104 X4 has garnered your interest, it can be yours for $166.81 from here.
It does look a little pricey for now, to be honest. Something like a QX90 could be a better option, especially considering the wide array of transmitters it supports… or perhaps something like the classic Tiny Whoop.
