RE: Hobbico FlyZone Cessna 182 Skylane EP RTF
The last step of the Cessna assembly was to install the antennas by simply pushing them down into position. If preferred, you can also glue them with white glue or foam-safe CA.
My Cessna 182 was Ready-To-Fly at 37oz including the battery pack. I did not measure the power level because the supplied connectors did not match anything I had for my wattmeter. My full throttle testing, while holding the plane, felt that it has plenty of power.
