I have the Zerokan with the update working in Windows 10 and with mine the trolley animation works just like normal landing gear. I can actually take off from a runway and then hit the G key and the trolley will disappear but the plane immediately pitches up. If I hit the G key again the trolley reappears and the plane pitches down. However the trolley is not for takeoff/landing, it's there to let you taxi to the ramp or beach and then splash into the water, then you hit the G key to make the trolley disappear. If you can dump the trolley in the water, you're good to go.
