The VS4-10 Phoenix features the Vanquish Products VFD Twin transmission (patent pending) and new F10 straight Axles. This combination provides performance advantages never before offered in a scale kit of its kind. The VFD Twin incorporates Selectable Overdrive Shifting and a 3-position dig unit into one compact package. The molded F10 Straight Axles utilize a high clearance design which minimizes the size of the pumpkin and maximizes strength around the C-hub and knuckle. Connecting the VFD Twin to the F10 Straight Axles are the ISD10 driveshafts. The ISD10 Driveshafts have machined CV style joints at each end with molded splined shafts between them for smooth and efficient performance.
