RE: GP Waco?
Mine does not have the choke servo but does have 2 elevator servos. It weighs about 14 1/2 #'s without fuel. It has the Dle 20 so has a little less weight there but has some alluminum motor mounts that add some ounces. It flies awesome and floats in on landings like it weighs 8#'s. I set the controls like the manual stated and it is right on. You're going to love it. Skillit's is set up like yours so ask him to compare with you.
Thanks,
Eddie
