If you re talking about Cobra Aviation in Australia...I ve had a good look @ their low wing and believe the airframe is a low tail version of the old PolywagonMessage 1 of 59 , May 1, 2004View SourceIf you're talking about Cobra Aviation in Australia...I've had a good look @
their low wing and believe the airframe is a low tail version of the old
Polywagon design (the latter used to have a T tail).

I really don,t know the degree setting. I watch my takeoff rpm. if I flatten it out a half degree it will raise the takeoff rpm about 2 to 300 rpm. If I backMessage 59 of 59 , May 3, 2004View SourceI really don,t know the degree setting. I watch my takeoff rpm. if I flatten it out a half degree it will raise the takeoff rpm about 2 to 300 rpm. If I back it off a half or so it will drop to 44 or 4500 rpm which is good for cross country. I flew it from here to Oshkosh and back that way. ( 40 hrs total at a little less than 4 gal per hr. ).I have found that 4700 takeoff rpm is the ideal for middle or happy medium. At that setting I top full out 118 mph at 5200 rpm.If I set it for max cruise at it will go up to 130 mph or over that, depending on density. It will then cruise at 115 mph all day long at 4850- 4900 rpm.I hope i didn,t confuse you.Keith with the Az. toy----- Original Message -----From: John AndersonSent: Monday, May 03, 2004 1:06 PMSubject: Re: [AirSoob]props
What blade angle is your happy medium Keith?
