In previous launches, we’ve had issues when some of the kids did not glue their fins on properly or their fins were not dry. Can you recommend any type of flash-curing glue so we can help prevent this in the future?

 

If the rocket has wooden fins, the best glue is Titebond Original Wood Glue #5062. It dries much quicker and stronger than white glue. Flash-curing glue (super glue) doesn’t have the shear strength for gluing fins onto the rocket tube and shouldn’t be used. If you need quick repair emergency glue for fins, then a very small amount of 2-part epoxy glue can be used. Be aware that this glue is heavy, and can change the weight balance of the rocket, causing an unstable flight.
