Yeap, I was told, these motors are hard on bearings however, Boca has some ceramic bearings that may be the answer. We will cross that bridge later.

I came to a decision, I will attempt to purchase some of the 16" Carbon Fiber blades or similar verse trying to adapt any of the standard props used now. May as well go for the gusto.

Mounting prop 15"


What do you think of this why of mounting a 15" prop??

I think that is a great way of doing it. Question, where did you purchase your props?

So do you have some props on the way then?

OK... what makes this thing attractive?
Beyond the larger moment arm provided by it's large diameter.
The windings certainly look to be as crappy as any I've yet seen

It's probably the lowest kv we know of in this size of motor. usually low kv motors are awfully big, but this one is a good size for a multirotor. Low kv lets you use direct drive on a large prop. It also drives required current down for a given power (while driving required voltage up). A larger prop has a higher g/W for a given thrust, as long as you have the right motor spinning it. With this we might be able to break a flight duration record.

Where are 16 in carbon props sold?

What is the height of the motor from base to the top of the bell where the props mount?

Question number one, I have no answer to that, but for question number two, it is about 7MM from the base to the bell.

I did some basic testing today with one of the RCTimer 5010 motors in connection with a 16x6 wooden prop I purchased off of Ebay. The prop was purchased for this reason only and was never intended to be used on a flight copter. Well, I am less then happy with the results and extremely happy I did not purchase those very expensive Carbon Fiber props now being sold by RCTimer. For the life of me, unless the CF props are extremely efficient and the copter is abnormally light, I just do not see getting the extended flight times now being reported.

In this test (not the most accurate), the amperage was about 8 amps on a 3S battery. This yield about 15.8 ounces of thrust at about 1.5ms PWM. I like using 1.5ms because that is about mid-stick and where I like to have my copters hover at. So for the sake of conversation, lets use a typical quad, so that would be four times 8 amps or 32 amps to yield about four pounds of thrust. Using a 5000mah battery (Assuming we would run it completely dead), that would net a flight time of about 9.375 minutes. I just don't get it.
