Engine Run - OS Max 46SF

The seconds of my pair of OS Max SF engines - this 46SF is almost as well worn as the 40SF - both have a ring gaps of around eight times what they'd be from the factory. nevertheless, they both start first flick and run great - amazing! Destined for a control line scale model in the future - possibly a Hawker Typhoon of around 1:12 to 1:10 scale.
