Horse Power per Pound?   Message List

Re: [NEDRA] Horse Power per Pound?

Hi again guys
 
 
Thanks again for the responses....I ran across this...and I must say I am amazed....and I thought you guys would be interested as well....
 
paragliders are not very efficient flying machines....the lift to drag ratio is probably only about half that of your typical cessna or piper cub...
 
And as we know, batteries arent exactly a light wieght way to store power...especially when compared to liquid fuels...
 
And when it comes to flying things wieght is everything !
 
But hey...the proof is in the pudding as they say...
 
here is the article link.....the video link is down near the bottom...kinda hiding under the bottom 3 pictures....video took awhile to load for me at least...
 
but still I am amazed!
