Cord is the width of the wing

Bipe stands for Biplane

Spar is a structural part of the wing. Some wings have only one near the front of the wing, some have two, both at the front and rear of the wing.

I do not mean to sound rude. If you are that new to the hobby then a biplane is not want you want at this point in time. Some are great handlers (Ultimate, Stearman, Hog Bipe, and a few others) The Pup is kinda twitchy and can be hard to control on the ground.

Again, I am not trying to be rude here. Just pointing out some facts.
