There are basicaly 3 "trainer" SPAD's the Debonair, BUHOR and SPADet they fly like any typical trainer wether its SPAD, balsa or composite (are there andy composite trainers?) the material a plane is made from has nothing to do with the way it flies providing the design is right (yes i know you cant make a plane from jello or other non suitable materials).

So Yes the SPAD trainers fly the same as any other trainer they are just tougher, so yes you heard wrong.

Oh and NO plane is unbreakable, it dosent matter what it's made from, some are just tougher.
