BIGGER ROCKETS
A high powered rocket is classified as a rocket that exceeds the total weight, total propellant, or single motor total impulse restrictions of a model rocket. HPR allows the use of metal structural components. High powered rockets have no total weight limit, but do have a single motor limit of more than O power (40,960ns maximum total impulse) and have a total power limitation of 81,920ns. Anything above that is classified as Amateur rocketry, where 101mm P class motors and up come into play and every part is made from scratch. I don't know much about amatuer rocketry so I won't try to explain it. Anyway, back to HPR. Unfortunately, with bigger rockets there bigger price tags. One thing you must also take into consideration, is the flying price of the rocket. The flying price is how much it costs you to launch once (the price of one engine, wadding and any other miscellaneous things). So, lets say you buy this really great rocket for $130.00. You want RMS so you need a casing, a rocket costing that much would be pretty big and would proabably take a 54mm casing and I or J reloads. A 54mm casing will cost about $100.00 and a J reload will be about $55.00 more. So in all, this rocket will cost you about $285.00 to launch the first time and $55.00 every other time. So you need to be able to afford to fly the rocket. A saying I go by is "make sure you can fly before you can buy" which basically means like a car, you have to be able to afford to maintain it and keep it running.
