A few years ago I participated in a pumpkin dropping contest at Courtland AL.
I needed some sort of external launch mechanism and came up with the following device.
It worked on the flat tips of my rocket by using a "spear" mounted on a pivot at the front of the wing. An electrically operated solenoid, (rear door window of old jeep cherokee), allowed the spear to rotate and drop the pumpkin.
On the first attempt I had premature pumpkulation and totally missed the airport.
My next pass, after landing and loading, at least hit in the area of the target, old outhouse.
As far as my research could determine there are no ballistic profile charts for pumpkins.
