Silver Hawk EX®

The Silver Hawk EX®, non-certified fuel injection system is proven technology drawn from decades of fuel metering engineering by Precision Airmotive® LLC. Manufactured as experimental, this Silver Hawk EX kit provides experimental aircraft with precise, dependable, and reliable fuel metering.

All Silver Hawk EX® Kits include:

New Servo
New Flow Divider*
New Nozzles*

* (Except EX235-2, single point injection and do not require or use a flow divider & nozzles)

There are no core charges with any experimental (“EX”) kits.
