The E-flite® UMX™ Pitts® S-1S aircraft makes it possible to enjoy the aerobatic icon of the century in your very own backyard. Even more amazing is how foreseeable this stunning bipe manages. That’s due to the fact that its AS3X® system has actually been custom-tuned to provide stability when you need it and dexterity when you desire it. The outcome is a scale aerobatic flight experience just like that of an expertly tuned giant-scale design. And the very best news of all is that you can enjoy it right away due to the fact that there’s no assembly needed.

The UMX™ Pitts® S-1S is designed so that the distinctive scale character comes through without sacrificing the efficiency benefits of a light wing loading. Not only is detail like rib and stringer detents evident, even the landing gear and tail wheel represent the celebrated functions of an aerobatic platform lots of full-blown pilots still utilize to this day for aerobatic competition.

The high-output brushless power system installed consists of an 180BL, 3000Kv outrunner motor and an E-flite® 5 x 2.75 propeller. Together they provide ample thrust for realistic scale aerobatic efficiency.

From the strong control of AS3X® system innovation, to the crisp response of efficiency linear long-throw servos, everything about the UMX Pitts S-1S is about delivering a strong scale aerobatic experience. Although it’s sized to fly just about anywhere, you get the accuracy and efficiency to fly like you’re in an air show.

The Artificial Stability – 3 aXis (AS3X®) system established by Horizon Hobby is an electronic development that makes the RC flight experience much better than ever. By establishing a unique combination of multi-axis sensors and exclusive software application, the AS3X system in the UMX™ Pitts® S-1S ultra micro biplane works behind the scenes while flying to provide immediate attitude corrections when turbulence, torque and idea stalls haphazardly disrupt the way you want to fly. The evident benefit is a plane that flies extremely smooth but likewise provides control that feels natural and entirely accurate. The outcome is an experience just like that of flying a much bigger, well-tuned scale design that’s remarkably convenient to fly.
