Thanks again Maynardrupp for reporting in on the gear again. That outfit in Swanton,Ohio is TnT?
I measured 3.6mm or 9/64" on the gear that came with my Extra. So this 1/8" gear should be 1/2oz lighter than factory by my calcs.
8/9 x 4.15 factory wt.= ~0.5 oz. Not bad, especially considering that your 1/8" gear should be stronger than the factory gear.
Looking forward to your next report: the test flight!

PS didja see the video link on Graphtec's site where the guy just POUNDS his gear?

Now THAT'S a hard landing (attempt). Almost what we affectionately refer to as a Pancake landing!
