It’s best not to risk using a too-cramped capsule.ĭual Egg Extension.
Eggs tend to vary significantly in diameter, so Easter Egg capsules are somewhat risky. However, Easter Egg capsules that small can be hard for the eggs to fit in and be safely cushioned. The faster the model boosts, the more strongly it needs to be built, to avoid shredding the fins at high speed.Įgg Capsule. Apogee offers a vac-formed egg capsule.Īnother capsule sometimes used is a plastic Easter Egg, of a size that is just a little bigger than an egg. Such capsules use two “long halves” from two 1.75″ diameter Easter eggs, rather than one plastic egg due to the short half with a flange sticking out, as the flange limits the inside diameter too much. This should translate to a straight boost, with minimal wobbling that would hurt the altitude. Work towards attaching all of the fins so they are straight and parallel to the body. A key to any event is building the model to fly straight and true. But they cannot be too heavy or they just will not fly safely enough with the added weight of an egg.īuild Well. Some regular models you might already have can be adapted to fly as an eggloft altitude model by replacing the nose cone with a capsule. The model will be draggier and usually heavier and therefore at a competitive disadvantage. A straight body tube with a larger diameter, such as 1.3″ to 1.65″ diameter (BT-55, 35mm, BT-60) can be used. Straight bodies have simplicity going for them, while shrouded bodies have lower drag and also have reliability in their favor due to the larger recovery system storage space. There are two general design approaches: an egglofter with a long tapered conical shroud such as the Two Minute Egg (see plan below) (Aerospace Specialty Products (ASP) has a similar kit) or a straight body-tubed model with capsule on top. The score is the best SINGLE qualified flight’s performance (altitude or duration) of the two flights allowed, if both are returned. The contestant may make one or two flights.
#Bottle rocket with egg and parachute full#
This is typically a “Large” grade of egg.įor the full rules for this event, please see the Egglofting Altitude rules, Dual Egglofting Altitude rules, Egglofting Duration rules, and Dual Egglofting Duration rules in the Model Rocket Sporting Code. Eggs must be 57 to 63 grams in weight, no more than 45 millimeters in diameter. You may NOT catch the egglofter it must be allowed to land naturally.
#Bottle rocket with egg and parachute cracked#
If any egg is cracked or broken, the flight is disqualified.
Eggloft combines the challenge of flying a model containing one or (for “Dual” Eggloft) two eggs while trying to reach the highest altitude (Eggloft Altitude) or longest duration (Eggloft Duration) possible.
