RE: TAKING OFF WITH FLAPS
Yes, but full flaps is not necessary. 10-20 degrees of flaps will increase mostly lift while going further than that will increase mostly drag which you don't necessarily want on take-off. Next time you fly on an airliner you can observe that they only use about 10 degrees for take-off. Only planes with ground clearance limitations on the tail, such as the Dornier DO-335 Pfeil use full flaps because they cannot rotate enough on take-off. I hope this helps...
