These guys from Regulators AirSoft built this prop to use in an arena in Springfield, MO. I wonder what’s inside this nice looking case…

The canister is made with red transparent .12 gram BB’s with two dozen strip red LED lights used for R/C Airplane night flying. Mock C-4 is made of clay. Power comes from a CPU power supply with a 11.1V Lipo battery. Blasting charges are made from .223 shells. Each switch has a function: power to cooling fan, power to canister, and power to all lights. The light around the power box is from a landing light kit from nitroplanes.com. What a fantastic build!
