The Madcow Rocketry Honest John Style M31 is a mid to high power fiberglass scale model of the 1950's vintage US Army Artillery Rocket. This Honest John uses a 29mm engine mount and a 2.6" diameter fiberglass main body tube.

  • Length: 38" (97 cm)
  • Diameter: 2.6" (3.4" at Nose)
  • Weight: 28 oz. (790 g)
  • Motor Mount: 29 mm.
  • Pre-Slotted FG Airframe. Scale Fiberglass Nose Cone. G10 Fins and Centering Rings
  • Recovery System: None included. 30" recommended
  • Scale: 1:8.5
  • CG: 29.5" from the nose tip.

This is an advanced kit.
You may need to adjust CG and either friction-fit your motor or use the retainer. Epoxy can cause an allergic reaction in some people. Adult supervision and wearing rubber gloves is recommended when working with epoxy. You need to sand the fiberglass nose cone and other fiberglass parts. Watch out for the fiberglass strands sticking up inside the nose cone - they are glass. Wear a particle mask to avoid breathing in the fiberglass dust. This kit is a big rocket, which requires extra safety precautions when flown. Patience and acquired flying skills to know when NOT to fly are just as important as quality construction techniques.

Since this is an advanced kit, we expect you to have launch equipment and experience building and launching mid-power rockets, therefore we do not provide the list of all required tools and materials for this rocket kit.
