The assumptions made in constructing this table are:
NOTE: these estimates do not apply to LDA models designed for 100m+ launches, which need much stronger wings. I had retired from the F1A game, become a glider pilot, and bought a Standard Libelle sailplane by the time LDA models arrived on the scene.
