【シグナスx】空冷→油冷→最終水冷エンジン！

Good evening everyone. This is M4 Tube! Thank you for watching ^^ Although it's a bit late, congratulations to everyone on a successful KTC (Kyoto University Championship). There's quite a time lag, but this video is the first part of the process of converting a Cygnus to water-cooling in preparation for KTC. Please watch until the end if you have the time ^^ #m4 #m4tube #CygnusX #CygnusX #Type3 #WaterCooling
