The Pichan launch site is located in Mantua Township, Portage County, Ohio, at 11919 Mantua Center Road, about one-half mile north of State Route 82. The range will be set up to the west of the property owner's garage/barn on the west side of Mantua Center Road. The launch and recovery areas are located in an area that was once a sod farm, but is now mostly in grass and weeds.
Including the neighboring land to the north and south,
the "clear" recovery area is about 1525' by 1600'. The neighbors are OK with
the goings-on and other than vegetable gardens, flower beds, a few isolated
trees, the occasional ditch, and a pole building, we are free to roam anywhere
in the entire area for recovery. The area to the south (separated by a very
deep drainage ditch) is covered with thistles and other thorny plants and has
come to be known as the "Field of Thorns"[tm]. If you will be retrieving
rockets, WEAR LONG PANTS! If your rocket lands in the "Field of Thorns"[tm]
and you are wearing shorts, MTMA will not be responsible for blood loss.
There is no high-power (Class 2 or higher) rocket waiver for this field. Rockets flown shall be limited to NFPA 1122 Model Rocket and FAA Class 1–Model Rocket. According to NFPA 1122, a model rocket weighs no more than 1,500 g with motors installed; is propelled by one or more model rocket motors having an installed total impulse of no more than 320 N-sec; and contains no more than 125 g of propellant weight. A model rocket motor has a total impulse of no greater than 160 N-sec, an average thrust of no greater than 80 N, and a propellant weight of no more than 62.5 g. A model rocket's structural parts, including the body, nose cone, and fins, shall be made of paper, wood, or plastic and shall contain no metal parts (metallic reloadable motor casings are permitted). According to FAR 101.22, Class 1–Model Rocket means an amateur rocket that (1) Uses no more than 125 grams (4.4 ounces) of propellant; (2) Uses a slow-burning propellant; (3) Is made of paper, wood, or breakable plastic; (4) Contains no substantial metal parts; and (5) Weighs no more than 1,500 grams (53 ounces), including the propellant. (This is a combination of the old "Model Rocket" and "Large Model Rocket" designations.)
All rockets to be launched are subject to approval by the Range Safety Officer (RSO) and the Launch Control Officer (LCO). For rockets weighing more than 16 ounces, the RSO will consult the "Waiver Table" from Rocketry Online's Info-Central (http://www.info-central.org/?article=114). If the predicted maximum altitude of any rocket / motor combination exceeds 1,000 feet in that table, a flight simulation shall be required. Flight simulations may be prepared using RockSim, wRASP, wRASP32, or ALTMARK - Model Rocket Altitude Predictor with an initial Cd of 0.35. A higher Cd will only be accepted if previously verified by altimeter-equipped flights.
