Gee Bee Y
The Pacific Aero ARF airframe weighs only 10 lbs without an engine. Granted, a G-23 will fly it, but the ZDZ40 is WAY too much for this light airframe. More like a Saito 150 or a YS 120, OS 120, Moki 180 may be too much.
Mine is going to use an RCS 140.
BTW, my NW Hobbies Gee Bee Y with a US41 weighed 20 lbs RTF dry. Their weight numbers have been (or are being) revised. They estimated quite low.
