This is a mini patrol boat. It took me three days to build it. The operation method is as follows: AG-1: machine gun, use Trim to control the angle of the machine gun up/down, use VTOL to control the muzzle towards AG-2: put away / DOWNLOAD ENGINE (VTOL) AG-3: Lighting AG-8: Main Engine Note: Please do not use machine gun shooting hull S.P.F.
