It seems that there are a lot of similar experiences but perhaps
what is needed is some common data on the flaps themselves. As a
guitar maker deflection testing is commonly done in my craft to find
the lightest/strongest wood and wouldn't something similar make
sense here? perhaps not the strongest per weight but most flexible
per weight??
Chris mentioned to me that he tests the flap by measuring on a gram
scale how many grams it takes to deflect the flap to zero degrees.
He feels that number should be one half of the glider weight.
Hopefully I have that right.
It would also seem that actual measuements of the flaps are only
somewhat useful given the above since the flexural strength of each
individual flap wood can differ.
Personally I prefer to develop a sense of this rather than measure
preferring things to be intuitive but in this case I don't really
have enough experience to do that.
Talking of times....I am envious of the times I see being mentioned
under Cat I sites where our own Cat II 37-39' site record stands at
less than 40 seconds. This 6500' altitude has quite an effect I
guess.
