wingload

What wingload on stiletto 120 will be equal to 1.4 on Stiletto 170 ( no I don't mean 1.4 that's too easy)
What wingload will give the same preformance, response, diving and turn speed

Well, no matter the same wingloading, no 2 sizes of the smae make of canopy perform the same. Larger ones have longer lines and dive longer and steeper. Smaller ones are way more twitchy, turn faster and don't dive near as long at the same loading due to thier shorter lines. Best guess.... like 1.3~1.35... but thats just a guess.

You're really asking two different questions!

Sounds like you're either poor (to put it mildly) at math or just plain lazy.However, here goes:
L is for wingload in pounds per square foot
W is for the suspended weight in pounds
A is for the area of the canopy (*) in square feet
The formula is: L=W/A
First, consider the Stiletto 170.
The only unknown variable is the weight. Isolating W from the formula for wingloading yields W=L*A.
L = 1.4 psf and A = 170 sqf hence W = 238 lbs.
Then, consider the Stiletto 120.
For the sake of simplicity, let's assume that the suspended weight remains the same. Then just fill in the formula:
W = 238 lbs and A = 120 sqf hence L = 1.98 psf.
Or, alternatively, you could say
For the Stiletto 170: L(170)=W/170
For the Stiletto 120: L(120)=W/120
Then isolate W from the first formula: W=170*L(170)
And substitute that into the second formula:
L(120)=170*L(170)/120=1.42*L(170) hence L(120) = 1.98 psf
(this way you don't need to explicitly calculate the weight first)
Conclusion: you'll be loading the 120 at 1.98:1, which is very agressive and quite a difference compared to your current wingload.

That's a totally different thing. Note Phreezone's reply. I couldn't tell since I don't jump an elliptical. I'm just a stupid novice. All I can do is point out that wingload is only one of many factors influencing the performance of a canopy.
(*): I'd rather write "the canopy's area" instead of "the area of the canopy", but I've once been taught that the former is really ugly (i.e. bad style) English when a lifeless object (as opposed to a person) is involved.

I'm backwards here... A larger canopy dives shallower then a smaller canopy. The shorter lines allowyou toswing out furtherand hold it longer.

I'm not stupid , my English may not be perfect but with math I don't have any problems .
just as Freezone understood my and had reply .So don't be a smart ass ( meer nuker)
thank's Amir
