When have I EVER been guilty of being balanced!?! I forgot, some of you guys are fairly new to the scene. Back in the 60s Renwal
released the 1/4 scale Visible V8, obviously based on the Chevy small block. Note the tranny is a 4-speed, dual range hydro! There was an electric motor in the starter motor that turned the engine. All the parts moved including the valves and distributor that 'fired' grain of wheat red light bulbs in the cylinders. Worked super until the camshaft snapped in half, or the flimsy distributor bracket snapped off, or one of the crank journals snapped off or . . .
picked up the molds and has re-released it several times over the years. None of the releases have structural improvements so they all self destruct within a few minutes of running.
