HI JBOY! If you have an engine mounted to a stick of wood, and the whole setup weighs a pound, the engine could put out 10 pounds of thrust and what would you have? If you put the same engine on a well designed plane that weighed 20 pounds, it could fly it, but the climb rate wouldn't be too hot. If you put the same engine on a plane that weighs 7 pounds, now you have a 3D plane that can hover, and explode out of a hover into a wild tumbling manuever. With 1/2A power, you can't afford to give any of it away, so it's good to know which prop works best for your application. It has become so easy to build a 240 sq. inch plane that is 4 channel, and weighs in the 12 to 16 oz range, that a reed 049 with 9ozs of thrust could fly it pretty well, and an 061 with 20 ozs of thrust could hover it.
combat,
what your saying is,you want a plane that weighs less than the amount of thurst an engine can produce...is that right???
i really like the way your meter works out to be very accurate...have you check any of the norvels yet...i'm wanting to see the difference between the TD.049 and the norvel.049...is the norvel really stronger than the TD???
