Solid Rust Twotter
I know a lot of people have some very unscientific ideas about downwind turns, to say the least. However, Sir C is correct that a downwind turn shortly after TO near the ground is not a clever idea. Remember that close to the ground in a CLIMBING downwind turn the aircraft will be turning into an INCREASING tailwind component due to wind gradient effect. Thus there will be a bleed off of airspeed while the aircrafts accelerates - the greater the windspeed and the steeper the climb out the more pronounced the effect. Pulling up the gear in a 210 at the same time is definitely not a particularly clever thing to do - plenty of 210 s have had propstrikes due to pilots pulling up the gear just after rotation.
