Here's my prangster... almost indestructible and flies great, can do more aerobatics than me....

So far loops, rolls, spins, inverted(tricky) squareish loops, stall turns, cuban and some more I invented by accident (the half stall turn anyone?).

Two trees and two straight down crashes, and no airframe damage at all.

Heartily recommended. If you want to learn to fly rather than to repair...
