Default RE: Sophistcated Lady Re-Do

Hi,
A buddy and myself are building GLs with the AG 35... airfoils (same as the alegro lite) and I beam spars, moving the battery and servos forward of the LE. This allows for balast weight to be fastened at the CG (using the Hook threads left long and a wing nut). No wind restrictions for us!
