Mike, I normally accelerate in something close to ground effect to a minimum
of 60kts and then progressively over about 2 secs pull up gear and flap.
Never noticed any tendency to sink, simply accelerates and starts to climb
nicely. If the engine goes I don't care too much whether I have got round to
putting the wheel down again. If you have runway to land on the damage is
negligible. If not you have much more serious things to worry about!
Regards, David Joyce
