Quadcopters

I am completely new to Drones and have purchased all the components I require to build it but I am running into an issue binding my FlySky FS-T6 to the receiver, I have tried binding it externally with a ESC and it works fine that way but from what I can tell the board is getting power but the receiver pins are not, unsure why this is as I can not see any visual issues but I have noticed the PDB is getting quite hot but not smoking or making any signs of it short circuiting however I am still very new to this so it may be that I am just missing something obvious. Any help would be great!

I am using a Turnigy MultiStar 30A BLHeli_32 4-In-1 Race Spec ESC W/ F4 FC, OSD & BEC (2-4S) control board, if anymore information is required feel free to ask, as I said I am quite new to drones and so may not be providing the correct information.

I created a full mod to enable Flysky FS-i6 and FS-i6X to use almost any frsky module on the market from TBS crossfire to R9M and even the Multiprotocol Modules.

Check it out have a detailed video on the build process also.

I need a 12*6 size propeller ...

I modeled up the DALRC ESC and Flight control boards for anyone needing to use as reference in their quad designs. If you have any requests for other boards let me know.
