I have a few experiences of the WhirlWind GA200L I would like to share… – The engine runs smoother – Fuel consumption appears to have decreased by 5-10% – Take off performance and climb performance is better, by appr. Whirlwind GA200L Propeller and Spinner Installation Video by Wasabi Air Racing The hub is CNC machined from aerospace aluminum, dimensionally certified and anodized. WhirlWind GA200L propellers come standard with electroformed Nickel leading edge for superior fit and abrasion protection. This advanced composite structure ensures high strength and blade accuracy in all flight environments. The blade structure is manufactured from theromoset epoxy/graphite composite matrix. Complete propeller, 13 in spinner and space kits available for easy assembly.The propeller is very durable with the Nickle leading edge from rain, sand and abrasion.With the 200GA propeller you can immediately take advantage of airframe/engine performance improvements simply by making a small pitch adjustment without the need of buying a new propeller or waiting to get the FP re-pitched. With a conventional fixed pitch (FP) propeller, small airframe clean up modifications and engine performance changes can necessitate a propeller change / re-pitch.Performance flexibility pitch to your performance preference, top end speed or super-efficient cruise.Why WhirlWind Ground Adjustable propeller? Even the cowl and fuse shape was taken into account when designing blade shape, twist and airfoils. Design features are optimized blade area, twist distribution and highly taped plan form for minimum induced drag. GA200L propeller is a purpose designed for RV airplanes with special attention to top end speed and cruise performance.
