Finally, the tight little FPV LKTR120 Frame Kit came out! It is a strong opponent in the micro custom built quad class. It comes with a frame and a outrunner motor. The frame is built firm enough being made of fiberglass, without power distribution board. The frame alone only weighs 14.1g, allocating a camera mounting space in the front with crash proof structure.
The whole quad is extremely mini as large as a lighter. To finish this kit off, you’ll need four 3A-6A ESCs (MultiStar 6A or MU-3A or MX-3A ) , a mini flight controller( OpenPilot CC3D Atom or AfroMini 32), battery( 2S 450 mAh or similar speced LiPos), propellers( Ladybird propeller or other 56mm propellers) and transmitter. For the FPV set-up, the optional HD 720p recording cams will fit this quad perfectly( Hubsan X4 H107C RC Quadcopter Spare Parts Camera Module 2MP). Motors are included, so you don’t need to prepare additionally.
The adopted motor is the brushless DP03 6500KV motor with a 1.5mm pitch white connector, it is also the smallest motor in the world that can drive 5030 propeller directly at high efficiency. But by changing propeller size, it can be also used both on 1S and 2S. As it is very small motor, propeller saver is not recommended because the propeller saver will be too heavy.
Prepare a screwdriver, insert the black bolts into the holes on the body, and stabilize using the screwdriver. Very simple.
Size comparison, we can see that FPV LKTR120 Frame Kit is really mini.
