FineScale 360 has began selling metal aluminum replacement frames for the Red Caboose O Scale GP9. The frames are intended to be used with the P&D hobbies repower kits and will not work with the stock motor set up that shipped with the original kits.
The frames are machined from 6061 aluminum alloy which ads quite a bit of weight to the plastic model. Additionally, two steal weights are provided to add even more weight if desired. Features include; Accessory wire channels machined into the top of the frame for ditch light or other wires, drilled speaker wire hole for fuel tank mounted speakers and prototype frame detail machined into the underside of the frame.
These frames look outstanding and I am looking forward to getting one (or two) for myself.
