We are a first year ARC team. We designed a rocket with a BT-70 top and BT-80 bottom section that is 29 in long. We estimated with open rocket that our design will be 305 g without motor (but with egg and payload) and using Openrocket are surprised how big of a motor we need. Two questions:
It seems really tough to find a motor that gets us really close to our desired altitude of 820 ft; I guess we'll need a bigger one and add weight?
To do that we seem to need an F size motor, which is the largest the competition allows. We thought we were making efficient design choices with the rocket and are surprised that we need the largest motor. Is this expected? Is our rocket heavy or poorly designed? Could we be doing something wrong in OpenRocket?
