Yes, knowing the models will help. Some seem to defy their listed weights, and almost all of them end up heavier than what is listed in the specs.

105g is 3.7 oz. A Big Bertha's catalog weight is 2.2 oz. and is about all a B4-4 or B6-4 wants. I would want completely calm air to make sure it was a 100% vertical flight. An Estes Mercury Redstone is listed at 3.7 oz. and absolutely needs a C5-3 or C6-3. What is the kit that crashed?

I love sanding.
