He he...I know EXACTLY what you mean!

I had OS .91s and Dynamax fans in both of them. weight was close to 50 pounds wet! One even flew at 64 pounds. Look at one of Bogo's latest version. He has done a very good job of engineering the lay-up process to lighten it up and maintain strength....proper materials in proper places. One of my Buds has one and is going to put two 200's in it! Amazing, as mine could maintin altitude with ONE Dynamax!
