iFlight SucceX Micro F4 V2.1 Flight Controller Stack 2-4S F4 FC + 4 in 1 15A ESC BLHeli_S + 5.8G Pit/25/100/200mW Transmitter VTX for FPV Micro Racing Drone Quadcopter

It's a solid little F4 and ESC with tiny solder pads as to be expected on a 16x16, but not much soldering needed and the pads have decent enough separation. But that VTX! Wow! I bought this thinking I'd definitely end up replacing the VTX for one with higher output power, but this 200mW surpasses all the mini 350mW's I use. Running on 3S with no cap and just the little whip antenna provided, and the picture is clean and clear where higher output ones turn snowy.Documentation claims the FC cannot run Frsky F-port with telemetry, but I've got everything working just fine with an inversion modded R-XSR.

This stack is very compact and looks quite nice but straight out of the box the vtx overheats in around 1 min. No video just static and will burn skin in contact. No help from seller and after doing some research it's apparently a known and common issue.

Holy cow I didn’t think it was that small. Pictures on the phone are bigger than real life lol hard for a beginner like me
