Super Sportster 72" Biplane 90 - 120 Size

The Super Sportster was originally produced in sizes from 20 to 60 size, and they quickly became popular models due to their outstanding flying characteristics.

We all know the bigger they are, the nicer they fly, so for those who like their aircraft with a 120 four stroke up the front, there's a 72" Super Sportster designed by Jim Feldmann that will be just perfect for 75 to 108 two stroke, or 90 to 120 four stroke power.

This version is the Super Sportster 72" in Biplane version. This is an exciting model to fly and easy to build, as the upper wing is attached using just centre struts. The controls are only on the lower wing, theoretically you can fly the model either as Bipe or as Low wing model.

If you've soloed anything more than a basic trainer, you can fly this model. With an OS 120 up front it will fly almost any sport aerobatic manoeuvre you can throw at it, and it will still slow right down for landing.

Our kitset includes a vacuum formed clear canopy.
