NEWS: Racerstar Crazybee F3

Want to build you own brushless tinywhoop easily without spending hours in microsoldering jobs ?. Here is maybe the solution with the Crazybee F3 4-in-1 board: https://www.banggood.com/Racerstar-Crazybee-F3-Flight-Controller-4-IN-1-5A-1S-Blheli_S-ESC-Compatible-Frsky-D8-Receiver-p-1262972.html

In the same board fully integraded in 29mmx29mm size, we have a F3 MCU + a builtin OSD, a 5A ESC BLheli_S/Dshot 600, a FrSky D8 with telemetry & RSSI and a BEC up to 0.8A enough to power an external small 25mW AIO module. The board weights only 3.5g. Brushless motors can be directly connected via 3 positions microJST connector (seems to be 1.25mm model). The board can only works in 1S for LiPo or LiHv batteries. Sounds to be a pretty interesting model. Ideal motors are 0603 or 0703 models. For example the HB68 or HB64 quadcopters comes with such kind of motors with plug.
