Starting to build the rocket that launched Voyager 1 and 2. Titan III E. Didn't have a tube to fit the size required for the satellite fairing so I cut down a tube I had from an old Saturn V, sliced it lengthwise and down sized the diameter to 78mm OS. Constructed the nose cone transitions from cardstock and ran them around a BT 20 tube along with centering rings at the changes in angle of the nose cone. The top rounded portion of the nose cone is a 20mm round wooden ball. All interior card board is cut from tissue paper boxes. Centering rings are made from Premium Crackers boxes. Cardstock transitions have an extra layer of cardstock glued to the inside of the cones for added strength. They are glued on in sections to ensure good contact with the exterior cone.
I'm modifying an OR file from a Titan III C to design the new model. Presently it's showing a weight of 466 grams without a motor and a stability caliber of 1.61
The question I've got here is can I fly this on a 24mm Aerotech E30-4 and or F44-4.Max lift off weight on the package specifies only 454 grams and I'm assuming this includes the weight of the motor. The weight of this rocket with this motor is 509 grams. OR flight simulation shows an apogee of 145meters (475') and a velocity of 12.8m/s (42ft/sec) of the rod. I'm using a 3/16" rod 6' long of which 5' is used by the rocket. So OR says it works.
I may have to upsize my motor mount to 29mm for a greater motor lifting capacity. I can always insert a 24mm conversion kit. The problem there is I can't get a 29 mm motor mount tube from my local hobby shop and will have to order it in. The tube would cost 3.20 and the shipping is 25.00.
