The "gun it and hold on" approach works for some planes, but I always shudder a little when I see it done. You're trusting too much to luck, low wing loading and high power loading, IMHO.

Usually the plane leaves the ground too soon, but you get away with it because the stall is soft and the plane has so much power it can pull out of trouble.

However, there are a lot of planes out there which will bite you if you try that approach. Try that with a heavily loaded scale warbird and you'll snap in to the ground for sure.

And it just looks wrong to go from standing still to airborne in a couple of steps. just totally wrong.
