Carl Goldberg Piper Cub
OS .46LA
APC 10X6
idle RPM 2500 pitch speed 14.77 MPH static thrust 0.20lbs
MAX RPM 12100 pitch speed 68.75 MPH static thrust 4.39lbs
WING AREA 744 SQ IN
MODEL WEIGHT 7.5lbs
wing loading 23.21oz.

I read an article in sport aviator mag about selecting a prop to match the model. if I understood it correctly,
the wingloading of a model is equal to the stall speed.giving this plane a stall speed of 23 MPH. acording to the
article the cruise speed is equal to twice the stall speed giving this plane a cruise speed of 46 MPH. for a
plane of this type they recommend a 1/3 thrust to weight ratio (vs a sport model like an extra which is recommended
a 1/1 ratio or greater) if I understand this right the idle pitch speed being 1/2 of the stall speed will act as an
effective brake which should allow a nice slow landing, the max pitch speed is actually much greater then the required
cruise speed so maybe a 10X5 prop would be a better selection.

does this make since?
following this theory,using a 10x5 prop, if I was able to keep the same idle RPM the pitch speed would be 12.31 MPH
and should slow the plane more, even adding 1000 RPM to the max RPM the pitch speed would be 61.55 MPH still more then
necessary for cruise speed and the static thrust would slightly increase to 5.07lbs still more then enough at .7/1 ratio

what do you think?
