However, I believe = the ES has a higher L/D than the Legacy -- most of the other Lancair = products do, as the Legacy is basically the tiniest wing with the = biggest engine they could design. You can create a lot of induced drag = by spiralling a Legacy. The ES is probably a much better glider which = would equate well to the Mooney 252 I owned. Speed brakes were VERY = useful on that airplane, which even with the gear down, had too good a = glide ratio. Like Paul, I'd say -- since you've got the pockets, put in = the brakes.
