So I have never used one of these longer burning motors before, but have always wanted to do so. I have an SBR 3" Nike smoke that is a reasonable candidate. It has a 54 mm MMT, and has an ebay with altimeter (egg timer apogee) in the nosecone for electronic deployment. Fully loaded the rocket weights 1400 g, with an I65 it would be 2150g (so like 4.75 lbs).
Open rocket says thrust:weight is 4.15: 1 (which I presume is based on the average thrust), but since this has a 'kick' off the pad with higher thrust for a few seconds before tapering off (and open rocket sims at 71 fps rail exit velocity), is this a reasonable rocket and motor combination? Would love to try this out at LDRS, but I want to make sure I am not thinking about this wrong.
