Default RE: KMP Beaver: Just started, looking for feedback

I am just about finished with the Beaver. Thanks to Morromaxx et al for the feedback, and to AKflyer and PaulGC for comments in an earlier thread.

Just one more thing before I put it up in the air... is the CG at 80mm appropriate, or have some of you (akflyer, PaulG-RC) modified this for better flight? Once I set this I'll be ready for wheeled flight, then on to the floats.

As most of you have, I set the wing-float incidence at 2.5 degrees by remaking the float struts from flat-stock aluminum bar. I also placed the step just behind (1.5cm) the CG (at 80mm, hopefully that CG value holds or I'll have to rework the float struts a bit more). Lastly, I remade the wire gear so I could spin a bigger prop (using a ZDZ 40, and I determined that a 20" prop would scrape when the tail lifts on take-off if I used the stock wire gear).

Looking forward to hearing someoneconfirm 80 mm.

Thanks
