SCARLETT 5 SERIES
The Verner Scarlett 5Si is a modern radial that brings real power in a minimal package at a great price. With specs and performance that put it right next to other 80HP engines, the Scarlett 5Si is still lighter than the other direct drive options and without the cost and complexity of the higher revving redrive engines of similar output. Verner makes this engine using the same cylinders and heads and systems as their already successful 7 cylinder engines, but reducing the weight and cost while keeping the power in a useful range. This motor would be a great fit for many aircraft that are out there today, and for those yet to come.
The Scarlett 5Si uses a throttle-body fuel injector with 2 main ports and 1 backup, distributing fual-air to all 5 cylinders. The engine will happily take both auto & aviation fuels. The electric starter is mounted direct to the back of the case. As with all Scarlett engines, the oil is a dry-sump system with return from the lower cylinders and the bottom of the case, and ignition is controlled by computer and fired by individual ignition coils.
The Verner Scarlett 5V is an ideal nexus of power and weight for a direct drive, air-cooled radial. There really isn't much trade-off comparing it to a traditional boxer VW: you save serious weight while making about the same horsepower, gaining the torque that 2640cc of displacement gets you. No bored and stroked 4 cylinder can match that. By taking the lightweight design of the 3V and adding an extra 2 cylinders, Verner has filled a vital niche for many aircraft, and in a form factor that looks irresistible, and sounds like a classic airplane should.
The Scarlett 5V uses a Walbro diaphragm type carburetor, distributing to all 5 cylinders and will take both auto & aviation fuels. The electric starter is optional, and easily installed or removed. As with all Scarlett engines, the oil is a dry-sump system with return from the lower cylinders and the bottom of the case, and ignition is controlled by computer and fired by individual ignition coils.
