Good Point, however ("i just switched the red/blue wires from my motor to esc") wouldn't the stock brushed 480 have red/black wires).

So, all of my foregoing talk that I've spent an hour preparing/editing about an assumed stock setup still has some relevance. Now can understand better that's why he's possibly experimenting with another prop that will provide better performance if it's a brushless setup in his SC. What doesn't make sense is why he didn't buy a tractor/puller prop instead of a pusher when there are so many electric tractor/puller designs from which to choose for trying out on a brushless setup. And why he is bothering having to drill out the center shaft hole on the prop when you can both buy the proper size spinner or proper hole dia. prop. (However, I remember all the mistakes I made during my learning curve that made it harder on me than necessary instead of easier ... live and learn). Any way the following is what I prepared before seeing your recent post.

Here’s a quote from the following APC link: http://www.apcprop.com/v/html/Pusher.html

“The APC line of electric pusher propellers is designed for counter clockwise (CCW) rotating tractor applications. These propellers are intended for use on airplanes with twin tractor electric motors where a CCW rotating propeller may be desirable. These propellers can also be used in a true pusher application by mounting with the ‘APC’ lettering facing towards the front of the aircraft.”

That’s why they are called a ‘pusher’ because when mounted on a rear motor pusher aircraft the lettering is correctly facing inward (unseen) toward the motor housing or “towards the front of the aircraft” when the motor is now rotating CW when viewed from behind the plane. However, when used for CCW tractor application the prop is flipped with the ‘APC’ lettering now facing away from the motor. So, when used as a tractor application it is possible to paint over or otherwise remove the lettering if the pilot thinks others will think he has the prop mounted backwards. If you don’t flip the prop on the motor shaft when converting a CW pusher to a CCW tractor the prop will be spinning with the trailing edge now being the leading edge resulting in poorer performance.

Assuming both the leading edge and trailing edge of the pusher propeller he was trying was an identical mirror image of each other(which is highly unlikely) then it wouldn’t be necessary to flip the prop on the shaft. You would only need to change the motor’s rotation when converting such a prop of identical symmetry from a pusher to a tractor/puller. However, a poorer difference in his SC flying performance may still be noticeable even if the prop had perfect symmetry so it didn’t need to be flipped. The reason being that the pusher prop he was trying may not be as efficient a design for his SC as the thin blade stock prop specifically designed for a SC DSM or LP.

Because the motor’s rotation is reversed from CW to CCW, the affected motor torque to the planes central axis is reversed. In order to reestablish the correct the thrust angle it would need to be a mirror image or in other words any slant or shiming toward one side from center axis would now need to be reverse shimmed the same amount off center axis toward the other side.

The bottomline is to use the recommended stock propeller unless you have modified the SC with a different power plant that may now require a different propeller to achieve maximum performance.
