I have the 60 size with a Saito 100... I just love the plane... When they lowered the price I had to get the little brother to mine. I know some people had a few problems with the 60. I was one of the first to get one and everything came out great... Just had to reenfoce the landing gear area on my 60 sz... I will go with a 40 fs on the 30. Did you guys do any other mods on yours? Inspected everything and all seems ok. Will be a while before I build this one... Finishing my Gee Bee
