Skyline F/X .049

The Skyline F/X .049 is not your Mama's Cox Sure Start. It is the top of the line super modified Cox reed valve .049. Using all of it's go fast parts Halfa Works' has built a pure blooded screamer. Turning an APC 4.2x4 racing prop at 23,000rpm this is the engine to mount on your 1/2a racer. Using a modified backplate and crankshaft coupled with a shortened and lightened piston the Skyline F/X  really hauls the mail. We top off the Skyline F/X with our high compression 1/2a TurboHead. All parts are hand fit to ensure every last bit of power. We add one of our needle nose spinners and a crankcase that is custom anodized the color of your choice.
