Sorry if this topic already exists I did a search but couldn't find one.
Is it better to fly at the top, middle or bottom of the manufacturer weight ranges. For example, Apco Force sizing:
Small=75-140 Medium=100-165 Large= 125-185
Pilot naked weight: 95kg.
Motor etc: 30kg
wing: 7Kg
fuel: 8kg
All up +/- 140kg
That puts the choice highish in the Medium and lowish in the Large. Lose some body weight/smaller motor and you have a top end of the Small. What considerations or other criteria should be applied to the choice?
My instinct would be Large for better glide, reduced motor noise, etc but also recognizing that I would lose some speed and agility (is this true?). Does this affect collapse resistance?
