well its been forever since i posted a gun. i have 4 more that i need to post ( i have advanced combustion MUCH bigger than this). but any way on to the gun. its all 1" it has one spark and a fan to mix the fuel and air. i use MAP gas for the fuel and .20 air soft bbs for the ammo. it has more power than any other mini that I have made i think its the fan. now for the pics i have one just for JSR to

the gun with all its tape.

just for you JSR

this is whats keeps my bbs from rolling out.

the fan,switch and 9v battery.

the fan blades i had to cut them so it would fit.

thats from 15ft.
