I swapped the W72GK46 prop on the Cub today. I haven't weighed the Cub since purchase so I'm using the info given.
EW 752lb
With pilot and full fuel: 1009 TOW
OAT about 72 to 77 degrees
Wind: about 9kts right on the nose
I didn't measure the ground roll but did "spot it" and plane to measure later. Large runways can be misleading but it looked like 150 to 200 feet(three to four seconds), what are you guys seeing with the 85hp engines under similar conditions? Don't have to break out the wizwheels, just general numbers.
I would like to get some actual measurements someday.
