It reduces ground roll by 20%.

It might get me into ground effect a bit earlier, but the end result
would take more distance to clear thatl 50 foot obstical.




One interesting characteristic of a soft field take off is if the up
elevator pressure is not eased off as the nose gear comes off the
plane will rotate into ground effect early and then settle back down
to never lift off again unless back pressure is eased off considerably
to allow the place to accelerate.


Uh, what? That has not been my experience. I have done numerous touch
and go's of this sort where I let it settle back on the runway as I was
accelerating on takeoff due to poor technique on my part. No doubt I

Yes, it would be due to poor technique, but unless the back pressure
is reduced the Deb will just go on down the runway, riding on the
mains, nose high.

slightly increased my takeoff distance but just leaving the controls
where they are the plane will takeoff just fine.

Even with 260 HP and a 3-blade prop, I have to let the nose down after
it settles or it won't acellerate enough to get back up.
