Update from Sebastian:  "I've been flying since September 2006, and I'm finally getting some flying pictures to you!  Just got them this weekend. You can add them to your customer collection. The engine is running great, love the Silver Hawk!"

John says: "I installed the Fuel servo on my Van's RV-6A with a Lycoming O-360-A3A, turning a Harzell CS prop. After a slight idle mixture and speed adjustment, it runs perfectly. The engine has been completely overhauled, with high compression pistons, polished ports, and an electronic ignition. The plane is flight ready. The maiden flight should be in the next few days."

This set of pictures shows John's workaround for resolving the issue of the mixture control lever interfering with the airbox in certain installations. As you can see in the pictures, John did a masterful job. However, this situation can be avoided by ordering the Silver Hawk with the alternate rotation mixture configuration. See the Kits & Applications page for details, or contact Product Support if you have any questions.

Ordinarily, the throat of the servo would be in the middle of the airbox mounting plate. Here, the plate is positioned off-center relative to the servo to prevent the mixture control lever from coming into contact with the airbox. In the alternate rotation mixture configuration, the mixture lever points toward the top of the servo, so that lever-airbox contact isn't an issue.

Airbox Modification

Fully-assembled airbox in place on the servo, seen from above and from the right side of the aircraft. Note the position of the mixture control lever on the right side of the picture, partially obscured by the airbox.

Airbox seen from the front of the aircraft. Again, the airbox is positioned off-center to accommodate the mixture control lever.

Airbox seen from the left side of the aircraft, with a close-up view of the mixture control lever.  Note how the lever protrudes into the space that the airbox would ordinarily occupy.

Silver Hawk EX with the alternate rotation mixture configuration, photographed at our shipping desk on its way out the door.  (It was a busy day in Shipping, which explains why someone's arm is in the picture.)  There are two main differences from the standard configuration.  First, the fuel line connects on the opposite side of the servo from the mixture control lever.  Second, the mixture control lever's range of motion is toward the top of the servo, not the bottom.  This solves the problem of lever-airbox contact that can occur in certain installations with the standard configuration of the Silver Hawk EX.

Again, if you have any questions about Silver Hawk EX configurations, please contact Product Support.

Alternate Configuration

John, thank you for sharing your pictures and for giving others the opportunity to benefit from your experience.  Very nicely done!

Scott's plane is a few months away from completion.  He'll share more pictures as he makes more progress.  We look forward to seeing what it looks like when it's all done!
