Thanks everyone for helping me understand. Now when my wife points out to me that I am gaining weight and getting fatter, I can just reply that I am actually working on flying faster. Love this sport.

Assuming they are using the same engine, of course :-)

Climbing is a function of excess power (over what is required for level
flight). The more excess power you have, the faster your rate of climb.

In level flight, your lift vector has only a vertical component (well,
there is a horizontal as well, but it is zero for all intents and
purposes of simple discussion). Pitch the wing up in a climb attitude
and the lift vector now has a measurable vertical and horizontal
component (since lift is perpendicular to the wing).

You aren't confused David.

The heavier the payload, the faster the wing flies. More HP only
creates more lift so you can ascend even quicker.

Now, if you do apply more power, it changes the angle of attack,
which changes the vertical lift vector and the horizontal speed. I
remember reading that discussion, but as I recall, it was a very
small percentage and at our speeds, wasn't a significant effect. As
I recall, almost not measureable, and definitely not with a
speedometer.

You put two pilots on the same wing side by side, the pilot with the
heaviest weight will fly faster. The lighter pilot on the other hand
will be able to climb faster. The heavier pilot needs to run at a
higher rpm to maintain the same level flight path as the lighter
pilot.

Arraignment Set For Ultralight Pilot Who Crashed Near Football Game
November 07, 2005

> "Flying under the influence" is one of the charges pending against a
man whose ultralight aircraft crashed just short of the field at a high
school football game in Blue Hill.
Dan VanBoening was also charged with two counts of assault, criminal
mischief and refusal to submit to a blood-alcohol test. Arraignment was
scheduled for Monday in Webster County Court.
Kathy Seeman of Blue Hill suffered a broken shoulder blade when the
plane hit her last Wednesday. The ultralight also damaged two motor
vehicles. <
