Horsepower required for level flight question...
Hi all...
Was reading about a glider the other day.... It has something like a sink rate of 125 feet per minute at a 400 pound total wieght when its going about 35 mph... Now given that 1foot pound/sec = .00182 HP and the glider is being powered by gravity.... 125 * 400 / 60 = 833 833 * 0.00182 = 1.5 So, are those calcs right and it would only take 1.5 horsepower to keep that glider going in level flight at 35 mph? If thats the case..it makes me wanna get a glider, a weed wacker with a prop on it and do some CHEAP, long, slow flights  take care Blll
