What I have found to be the best technique in the Helio at about 3100lbs is
to slow way down to about 45kts. This will yeild about 500fpm with 11"MP
which is a steep descent. When I am about 200AGL, I increase speed to 55kts
to provide energy for the flair. You can brake as hard as possible with the
Helio and there is no chance of it nosing over because the gear is so far
forward.

What I found last week is that these speeds and power setting do not work
well at 3400lb. I need quite a bit more speed. I will have to figure out
what the numbers should be. I was quite surprised at the difference.

Try 50 initial, accelerate to 60 at 3400 lbs.
(that's a guess using math formula based on what you posted)

To be accurate, I need max gross weight and stall speed at max gross.
