4″ Little John

Madcow Rocketry 4" Little John

Length: 47.5″

Diameter: 4″

Weight: 45oz without nose weight

Motor Mount: 38mm

I built Madcow Rocketry’s sport-scale version of the Army’s Little John artillery rocket to use it for my NAR Jr. Level 1 certification flight. At WAC’s 2010 March launch, my cert. flight on an AeroTech H148 went perfectly. Every one of the Little John’s subsequent flights has been successful as well.

  1. Yes. I made the nose weight in mine modular using the method shown HERE. 4oz of nose weight (not including the eye bolt) works for most 29mm motors and 2-grain 38mm motors. I have put up to six ounces in it for a flight on an AeroTech I154 (38mm 4-grain).
