A Brace of Pibri


Slope racing pilot Richard Frawley writes:

"I had my first introduction to the Pibros in March of 1997 at the Spanish F3F at Arilla. The French F3F team brought five of these delightful craft to the event.

What is great about the Pibros is that there is no fear about handing the sticks to another pilot. There is little chance that irreparable damage can be sustained.

As far as flight performance goes, I wasn’t disappointed. The hardest part was handing back the controls. I was hooked, I wanted one and I wanted one now!"
