perjar,
That's a classic too much elevator, not enough airspeed take-off. It's amazing how many "experienced" guys do this every time they take off.

As it was very well said above, just let the plane roll a big longer and get going a bit faster, and don't pull up nearly as quickly and use a much more gradual climbout, and you'll be fine. It's a matter of fine adjustment, not radical changes to what you are doing.

I loved that story about the guy in the 182. Classic.

Even with my acrobatic planes, I like to go tearing down the runway, lift off real slow, so it's hard to tell just when the wheels leave the ground, then zoom down the runway about a foot up, slowly climb to a few feet. Then, once I've done that, I can pull vertical, or roll, or do a hard bank around the field or whatever show off things I want with out worrying about stalling. Makes you look good, but is really just being safe
