Test of the hover controller, in particular in yaw direction (multicopter frame, i.e. roll direction in airplane frame). The yaw is stabilized using the flaperons which are in the propeller wash. The flaperon deflections are visible when Chris pokes the kite with the broom. The controller quickly reacts and stabilizes smoothly the yaw angle back to zero. Note that differential propeller directions as used for small multicopter-drones do not offer nearly enough yaw moment for control authority of the kite's inertia or expected wind loads. In addition, such a control scheme greatly reduces the thrust for yaw stabilization. This is why this is not feasible for our system.

► Full test in Multihulls World 189: https://www.multihulls-world.com/review/motor/leopard-40-pc-maximum-comfort-in-compact-size ► A third powercat in the Leopard range. ► Following the launch of two large models - the 53 and 46PC - and the retirement of the very successful 43PC, it came as no surprise to discover a new compact model from Robertson & Caine, the 40PC. In terms of design, this powercat blends perfectly into the new range with very long hull windows and an immense flybridge. It features an imposing panoramic coachroof with a beautiful L-shaped galley and, despite being shorter in length, manages to house great cabins all equipped with island beds and bathrooms. But the real plus compared to the 43PC? Aboard this model, there’s a proper interior helm station. ► TECHNICAL SPECIFICATIONS Builder: Robertson & Caine Length: 40’ (12.19 m) Waterline length: 39’7” (12.07 m) Beam: 21’8” (6.61 m) Draft: 3’5” (1.04 m) Displacement: 28,819 lbs (13.07 t) Water: 170 US gal (640 l) Fuel: 370 US gal (1,400 l) Engines: 2 x 250 - 320 - 370 HP Cruising speed: 17 knots Top speed: over 20 knots ► Become a FREE SUBSCRIBER to Multihulls World's YouTube page now - https://www.youtube.com/c/MultihullsWorld ► Log on to our website to discover over 500 multihulls tests!
