Our aircraft was designed with 655 sq inches of wing area while keeping the total weight to a 
minimum. Whether you want an aircraft precise enough to compete in IMAC or 3D until you’re 
airsick, the PAU Extra fits the bill. Its light weight gives you the stability in high-alpha to take it to 
the extremes of the flight envelope. If tumbling maneuvers are your thing, our Extra 300sp will 
deliver with picture perfect waterfalls and blistering tip spins that are not for the faint of heart. 

We believe you will find this to be one of the finest flying aircraft on the market.  Most modelers 
will find assembly of this aircraft simple and straightforward.  We recommend the builder follow 
the step-by-step instructions to achieve the best performance and to ensure nothing was over 
looked.  This manual also includes tip sections throughout that may help you in key areas during 
assembly.  Please familiarize yourself with this manual before assembly.
