SwitchBack Sr

The SwitchBack is still refered to as "The Original Parkfyer" on the online groups. So, how do you make it even better? Scale it up 50%, update the construction, and slightly tweak the design for an even better performing model!

Paying attention to material selection and design, we've kept this 55" SwitchBack Senior down to a paltry 34 to 37 ounces! With a light wing loading and smooth flying characteristics, the SwitchBack Senior would make a great low wing aileron trainer. Open up the throttle and increase the rates on the controls and get ready for a barn burning, sky tearing aerobatic plane!

As with all of our kits, construction is simple with the interlocking parts. You you won't have to run to the hobby shop for hardware either, because we've included everything you need.
