Well as my user name suggests I am a die-hard Ergo fan. And I can say from years of experience flying them, all the way from the lowly 30 to the 46, the 60, and the Z230. NONE, and I mean NONE of them have ever had any flutter, woof and poof, clutch problems, or anything that needed any expensive upgrades to fix. The only upgrade I ever did on my 30 was a 46 upgrade kit. The 60s(yes more than one) I have have been from bone stock, to a fully metal one that I bought that way, and to tell the truth the full metal one flew no different than my bone stock one. The only upgrade you need for a Ergo is a nice set of blades. Nothing against the woodies, but I just dont like the balancing part.

The best testimonial to date is my friend who has been flying his "Stock" Ergo 60 for three years now with all the origional parts, exceptfor the blades of course, and he is now playing around with a 90 in it, but all the origional parts are there, and he tears it up at the field.

Man I love the Ergo's
