A sleek and powerful plane engine that supports counter-rotating propellers, or a single larger propeller.
This engine doesn't overheat while under load, but it will overheat if left at max throttle with zero prop collective.
The coolant pumps are controlled by a microcontroller that turns them on shortly after the engine starts, the green throttle levers, dial and buttons are a control / debug panel for the engine.
This engine doesn't have any sort of safety systems, nor does it have a kill switch or power boost option. Those are available on the larger engines.
This engine is compatible with central and/or under wing mounting configurations and is relatively lightweight.
The propeller clutch pack is controlled by a combination of the prop collective (pitch) lever, engine RPS and generator output.
You may use this as you see fit, enjoy.
