Meesh -

Go with the pull-pull! I believe the original intent was to have the elevator servo in the rear, however, unless you are using a heavy gas burner it will only make your aircraft tail heavy! The pull-pull is much more efficient anyway. I installed an Enya 155 in mine and it balances perfect. Just waiting for the weather to turn better and the holiday season to pass before I start burning fuel! By the way, isn't that one sweet airplane!
