Burning questions provoked by Van's RV–15 tease

From the video and previous statements from Van's, here's what we know about the RV–15, what we think we know, and what we don't yet know.

What we know

• High-wing, metal, strut-braced, tailwheel, two side doors with room inside for up to four seats.
• Four-cylinder Lycoming engine with Hartzell constant-speed propeller and Beringer wheels and brakes.
• Wide-span Fowler flaps that are manually activated via an overhead handle.
• A "flying" horizontal stabilizer for elevator trim, and a large counterweighted rudder.
• Pushrod-actuated ailerons and elevator.
• Impressive short takeoff and landing performance with a roughly four-second takeoff roll (with flaps up).

What we think we know

• Lycoming IO-390 engine.
• The metal main landing gear are dampened by internal nitrogen/oil shock absorbers, as is the tailwheel.
• Control sticks, not yokes.
• Fuel stored in the wings (even though the prototype has a fuel tank in the fuselage).
• Forward-hinged transparent doors.

What we don't know

• Does the big vertical tail mean a seaplane version is in the works?
• Will there be a nosewheel version?
• When will kits be available? And how much will they cost?
• What are the biggest tires it can accommodate?
• Are handling qualities similar to the rest of the RV series?
• Performance?

We'll be among the first to check it out and report from EAA AirVenture Oshkosh.
