    Hey guys! To start, here is a quick list of my parts:

    Blackwidow V2 Frame from TMDRONES (sick looking frame)
    Hobbywing Xrotor Micro 4 in 1 ESC/PDB
    SP Racing F3 FC
    TBS Unify Pro (Race)
    FrSky XM+ SBUS Mini Receiver

    So the problem I'm having right now is that I can't fit my FC on my frame! It's like the holes are too small for the 30.5mm bolts that is supposed to hold everything in. The ESC fits right in no problem but the FC won't. Should I try reaming out the holes on the FC so it could fit on or will that damage it? Of course I'll be careful not to ream it out too big but that shouldn't be a problem right? Here is a video of what I am dealing with.

    Next question is after I hook up the ESC to the motors and figure out how to mount the FC, all I have to do to connect them is wire up the S1, S2, S3, S4, +, and - to the FC right?
    Like this:


    Then all I need to do is mount my Radio Receiver like this but without the blue wire:


    But how do I wire my VTX? Anything else I'm missing?

    Also how do I display my voltage on my Fat Shark?

    I don't know about your other questions, but I've seen a couple guys that do build videos that ream out the holes a little on the FCB. They just used a small round needle file.

    Hi mate you should not mount it with metal bolts use plastic bolts so nothing can short out and in crash the plastic bolts will snap not the FCB

    There is no vtx input on an spf3, you will have to run off a 5v or 12v bec.
    Does your vtx output 5v for the camera.
    If so plug the camera in & supply 12v to the vtx & good to go. I wouldn't use anything other than these to mount the fcb 8-pcs-m5-air-compressor-rubber-vibration-mount-isolator-15mm-x-15mm-1024x1024.jpg
    They come in 2.5mm & 3mm.
