I got the yeah racing setup to go on, you just open it up a bit and it all bolts on. But, i just ordered some juicy 12v fans so i might put the yeah racing on the castle 1520, buy x2 Alza-Racing 40mm mounts and put 2 of the big fans on (27,000rpm 36CFM 12VDC ).
Just got to work out how to power them lol, i know i only need the red and black but i assume i dont plug this into the receive box, maybe make something to connect it to balance port or a small 3s lipo
