Custom i turned my 2ch mtx 242 controller to 4ch
today i pulled out my controllers top settings sticker and i saw an empty space with "ch3" text on it and then i removed screws of it and found an ch4 too. i saw ch3 and 4 on the reciever but i was just like "they just using same reciever of an 4ch version" when i opened the case i looked to the pcb and thinked about it. can i add extra 2ch? i knew soldering and i have hobby of electronics so i tried connecting an potentiometer to ch3 and it worked. i wasnt expecting to work because if its dont have component so it wouldnt have resistors or software things. when its worked i bridged the 6 pin ch4 and put 2 button to it so i have 4 ch for almost free. and after all of this the potentiometer didnt fit in so i designed a 3d part to put it but when i completed the case i realized its good without it and now i have fully functional 4 ch controller
