I call it marvellous, wonderful and beautiful . Master J calls it a discus launch glider and says it doesn't fly that well, that next time he'll add ailerons in addition to the rudder and elevators of this plane. Next time he says he'll increase the dihedral so it will be more responsive.
I still declare it excellent and amazing. You see Master J designed and built this one from scratch, totally unassisted for his Design and Technology subject at school.
What's not to love about that!
