The E-flite® UMX™ Pitts® S-1S airplane makes it possible to enjoy the aerobatic icon of the century in your own back yard. Even more remarkable is how predictable this beautiful bipe handles. That’s because its AS3X® system has been custom-tuned to deliver stability when you need it and agility when you want it. The result is a scale aerobatic flight experience similar to that of an expertly tuned giant-scale model. And the best news of all is that you can enjoy it right away because there’s no assembly required.
