[saugumas]

Hello,
I am interested in aviation and found few pretty impressive homebuilt mico jet application examples.
Simple construcion homebuild flying jet, about 5-10 pounds of thrust, http://www.youtube.com/watch?v=pztUJRzOaNs, http://www.youtube.com/watch?v=5XbTzfAFNgE.
And another ultralight aircraft powered by two micro jets(5 pounds each) : http://www.youtube.com/watch?v=R9bzQQl8Y_w

also cool video with jet powred hangglider: http://www.youtube.com/watch?v=_AXuy2-Y ... re=related

Maybe anyone else is interested in small homebuilt jet engines application in homebuilt ultralight aircrafts?
