hey i just bought a tensor 4d and i have a question about the building of it. wat is a good way to keep the wings perfectly level when glueing in place.

Probably a little late but I use a plastic right angle triangle. Be gentle with it. It's a very fragile plane but works well. Mine was more glue than foam before I retired it.

its a fragile plane huh? wat is a flat foam plane that is not fragile then??? I just want a strong, durable flat foamy that i can do snaps with and not break it.
