A Fresh rookie, just bought my X racer F4 FC, can anyone tell me the process of FC installation? I have martian3, 4xESC, 4xEMAX(CW & CCW), Matek HUBOSD, i know how to soldering these parts except for FC. Is there any parts i missed? Please share your precious opinion to me,thanks.

Welcome to the forum. I don't see a receiver on your list. What radio system do you have?

I recommend you watch Joshua Bardwell video series how to wire a FC. Too much information for any of us to convey in a forum setting.

Hi, RENOV8R thanks for the help,

Well, I can show you my full list(somebody's list):

FC: Xracer F4
Body: Martian3
ESC: DYS XS20A
Motor:EMAX(CW & CCW)
PDB:Matek HUBOSD
Propellers:10 sets 2 wings
FPV transmitter: TS5823S 5.8G/200MW
FPV Camera: Foxeer Arrow HS1190
FPV Glass: n/A
Radio transmitter: Taranis(not buying yet)
Radio receiver: Fs ia6b 2.4G(not buying yet)

I want to have a stable transmit flight on my own, which parts do I miss?(I assume alot XD)

Your radio receiver is a Flysky and not compatible with a Taranis. As Voodoo said, there is much research to do before you build your quad. Youtube is your friend.

I would consider an AIO FC (FC, OSD, and PDB). Cost will be the same because you will not need PDB. Built-in OSD through BFC is very easy.

Also brushless motors can spin in either direction, and most people just buy standard threaded (CW) motors and use nylock nuts (often included). The most important info for your motors are size and KV. For example I have some EFAW 2407 2550 KV motors, 24mm wide, 7mm tall, and the (max theoretical) rpm would be 2550 x battery voltage.

Thanks, dudes.

Mr. Bardwell is my friend now.

FC: Xracer F4
Body: Martian3
ESC: DYS XS20A BLS
Motor:EMAX RS2205 2300KV(CW & CCW) brushless
PDB:Matek HUBOSD eco H
Propellers:10 sets 2 wings
FPV transmitter: TS5823S 5.8G/200MW
FPV Camera: Foxeer Arrow HS1190 600tvl
FPV Glass: n/A
Radio transmitter: TBD
Radio receiver: Fs ia6b 2.4G(not buying yet)

If my receiver is FS ia6b, how would you guys suggest my transmitter? well, I found FS i6s, cheaper one, don't know its reliability...

Those ESCs aren't DShot ready and I'd go 30A as those Emax motors draw a fair amount of current. These have worked well for me

Well, 20A w/o Dshot would be unstable? or my motors wouldnt have good performance? if so, maybe another order.

Those Emax motors can easily pull over 30 amps

DSHOT will allow you to do things like crash flip, where if your ESC is not DSHOT you can't.  Also you won't need to calibrate the ESCs with DSHOT.

I would suggest going with Frsky instead of the RX you're listing.  Since you haven't bought a TX yet, think about getting a Taranis Q7 and an R-XSR or XM+ receiver.
