Joe I tried an 18.1x10w and it pulled the rpm's down so far (7200) I was afraid to try it.
Rereading Akiba's email I believe the translation was bad. He stated Zero right and 3.5 degrees of down. I think he meant 3.5 right and zero down. I agree on the cg when I went from 195 to 175 I didn't see that much difference.
I've gotten the second kit yesterday. I'll weigh this one tonight and see how it compares to the 1st. I plan on doing a build thread on this one if anyone is interested.
I did bolt the wing down last night and one of the front wing bolts wouldn't align. A few minutes with a drill and bit and all is well. Going through all the stuff I ordered from Central I got everything for the build but the right mount. I ordered an AR-80 mount and they sent me a YS63 mount.

I need to figure out how to add pic's to posts.
