I have looked in several locations, but I have not been able to determine how much black powder to use for ejection. Is their an equation? I'm going to use a Madcow Squat for my Level 1 and it has a very small cavity for the parachute.
Problem With the 1 gram to 1 inch formula is it really doesn't make any allowance for total volume. Guess there should be a multiplication factor for length to be pressurized.
Well,, a lot of folks use a down and dirty way to calculate ejection charges, 1gr for each inch of airframe diameter. 1" diameter = 1gr bp, 4" diameter = 4gr. ect ect ect.
