The Widgeon is a beautiful plane. Grumman aircraft in general are fabulous!

I am going to try and save as much weight as I can on my build, I don't want to end up with an airboat! I go down to Lake Hood sometimes just to watch the float planes take-off. Some of those guys get so much weight in their planes they have a heck of a time breaking the suction of the water. I am sure the same principle applys to a model.

Since I am doing my week out of town at work, I have some time to re-read these threads and get my head full of ideas to take back to the build. After looking at reviews on lots of transmitters, I've decided to get a Futaba 7C.

Electrify PBY specs

Wingspan: 53.5 in (1360 mm)
Wing Area: 395 inē (25.5 dmē)
Weight: 3-3.25 lb (1.36-1.47 kg)
Wing Loading: 18-19 oz/ftē (55-58 g/dmē)
Length: 34.25 in (870 mm)
Requires: 4+ channel radio w/4 micro servos, two 950kV brushless outrunner motors, two 25A brushless ESCs, 11.1V 2100-3200mAh LiPo battery

Looking at the specs for your plane gives me optimisim as I am shooting for around 32oz. with a wing area of 306 sq. in.. I am curious where the CG is on your plane. I think Phil ended up with his real close to the LE with his Guillows PBY. Phil's plane flys very good, but I do not know if he ever had a successful ROW, even though I think he proved the plane was definitely capable of it. I am wondering if a compromise needs to be made between best fly-ability vs. ability to ROW, or if the two can go hand in hand?

So many questions,...sorry!
