Sprit of Spec Wing™ Racing: All airframes will be competitively equal in order to provide an even competition base for all Pilots.

**** ALL Spec Wing™ airframes should conform to the Spirit of Spec-Wing Racing.

**** ALL Spec Wings are subject to prerace and postrace inspections. (See Spec inspection process)

The following is a list of Manufacturers who have submitted Spec Wing™ Kits for inspection and have been granted Official FPVWRA® approval and will be permitted to race at FPVWRA® Officially sanctioned events. Kits that have been "Spec Approved" are designed to and meet the Spec Class design and standards. These kits have passed FPVWRA® scrutiny, and as such should have zero issues passing tech inspections on race day. Spec Wings purchased through the FPVWRA® Store will include a "Spec Approved" sticker that should be applied to the completed airframe, allowing the operator to breeze through inspections in seconds rather than minutes.

*Must be able to race for a minimum of 4 minutes.

*Novice Class is intended to be a beginner only class. The Class' intent is to allow anyone who has never raced in an FPVWRA event the opportunity to get try racing without building an aircraft that fits into any specific class. It is up to the Event/Race Director to manage the pilots in this class. Our Recommendation is anyone who participates in any of the Regulated Classes on a regular basis should not race in the Novice class. Event/Race directors have discretion to allow anyone to participate in an effort to place as many pilots in the Novice class races as possible.
