Pete, Got, it, both responses. Gonna fly BIG BIRDS Friday, but the EZE is going to go along and may make the big jump... Will post results if it happens. One more question... I noticed that there are at least two cowls... one with scoops on the side and like mine, no scoops. Do you fly cowled or not. If so how about engine cooling ? I'm going to fly first few without cowl, should not make any aerodynamic difference. I'm flying with a TT.46 Pro and APC 11-7.5, that's what I use on the other pusher with good results. Cliff
