Seems like if the prop was stalled, you would not get nearly the

expected

static thrust. Do you need lots of brake to hold it?

Chuck Dunlap

Good idea Chuck. Get a large spring scale and measure the static thrust.
A garage door spring will work if it is calibrated. Tie it to a large

tree.

Paul Lamar

Well, you could be correct, Chuck.  I had always hear that a "stalled" prop
would turn faster than a "loaded - unstalled" prop, but I have no personal
experience with one.  I have chocks on each main gear, one in front of the
nose wheel and stand on the brakes when at 5800 rpm.  The plane shudders,
bounces and shakes, but has not lifted straight up {:>).

>From what I read about a "Stalled" prop, one way of telling if your prop was
stalled is if during takeoff roll or shortly after lift off the rpm drops
several hundred rpm then your prop just "unstalled" and loaded the engine
causing the decrease in rpm.  I would rather not have that happen during
take off (causes for heart palpitations {{:>).
