When it came to the engine choice our main priority was reliability. Of course the available power was an issue as well - the Corsair should have minimum 30 hp.
Therefore we selected the Verner Scarlett 3 V - a 4-stroke, 3-cylinder radial engine. The engine is purposefully designed as a light aircraft engine and produces 42 bhp at 2500 rpm. This power and a displacement of 1,6 liter already shows that this is a robust engine and not one of those highly tuned cart-, lawn mower- or scooter engines.
The high engine torque allows the use of a rather big and efficient propeller. We have two standard options: either a ground adjustable 3-blade 1,60 m carbon prop which can produce - depending on the blade pitch - up to 100 kg of static thrust. Or we offer the 1,75 m Helix 2- or 3-blade props which both even deliver more than 100 kg thrust. More than enough for 120 kg empty weight!
And as a side effect the sound of this engine is just fantastic!

Whatever your choice - either we build it or help you to install it on your kit and provide you with drawings, parts and recommendations for installation and a good propeller selection.
