 UMX

 Pitts

®

 S-1S ultra micro airplane. Despite its size, this model 

has been engineered to deliver a potent scale model that handles great. Molded lightweight foam 

construction makes it possible for the high-output brushless power system installed to provide quick 
acceleration and strong vertical climbs. Four performance linear long-throw servos provide precision 
control. But what truly makes this go-anywhere biplane special is the remarkable AS3X

®

 system that’s been 

specially tuned to give you the feeling of fl ying a much larger model. AS3X stability works especially hard so 
even when wind conditions are moderate, you experience the kind of smooth fl ight that makes you want to 
fl y more often. 

A thorough read of this manual will help assure that you’re well equipped to successfully enjoy all the 
benefi ts this outstanding ultra micro model has to offer.
