Nicholdime,
Are you sure that no other aerodynamic improvements were made to the old glider that you recovered.
If not, then you have provided the response to your question.

Thanks for all the info .I was looking for objective conformation rather than my subjective "I've put a lot of work into the model so it must be better" and the lift is beeter today than when I last flew it in its rough state.
I wonder whether it would be wort while setting up a crude wind tunnel out of some boxes and a fan and doing some simple experiments ?
