Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !

Optimum effectiveness of the parachute, use shroud lines 1.5 times the diameter of the chute....A hole in the top of the parachute helps to keep the rocket from spinning on it's way down (trapped air doesn't "spill" out the side but instead goes thru the "spill hole". How heavy is the rocket (with empty motor casings)? A spill hole will speed the descent.

Hi Don and thanks 4 reply. I'm going to say this bird is about 6-8 ounces. Glad u told me "shroud line ref. I think mine r too short. First shut I ever used on this thing was an old handkerchief and pretty heavy. Launched it from "Lake Hopatcong", when it was frozen 25 years ago. Weather not looking to promising for Saturday. We'll have to see. Thanks, Glenn

These web site has a program to help calculate the size parachute you need for a given rocket...
