I have a friend that said people would drive across three states to see someone TRY to fly a Nosen plane with the Dubro reduction unit. He also said that you had to have the needle set perfect, good fuel,and even the weather had to be just right in order for one of them to STRUGGLE into the air...You might get a kick over this adapted Dubro reduction unit my buddy modified for me.. it has yet to be mounted in an air frame or flown on anything yet ...
I don' t think I have ever seen a video of a plane flying using the Dubro reduction ..
