First of all, Hello elenasgrumpy, Have not seen you around here for some time. Hope your doing better.

Anyway Dave you never mentioned which Chipmunk you were looking at. I have seen good ones and not so good ones. There is a no name el' cheepo out there in the 40 size selling for anywhere between $69 and $89 that has a fiberglass fuse that my buddy got and it was absolute junk. Knowing what we know now we could have modified it and made it work but it was still over weight for a .46 then he tried to put a Tower .75 in it and it nearly fluttered it's self to death. Warning... you get what you pay for.
