P-Limited Motors - Im going to jump on the hot seat.

[Darin Jordan]

Received a "care-package" from OSE and TFL Hobbies yesterday. I think I have all the motors I need for now.

Heading to the LA SAW event tomorrow morning and will be gone for about a week. Once I get back and get settled in again, I'll start testing these and get the results published.

Bench is about cleared off. Going to start dedicating some time to testing all these motors this week. Results should start getting posted shortly there-after.

Could you post a list of the motors,
???? KV
# of wind , "Y" or "D"

Would the Timing setting be #0 for "D" and #12 for "Y"

I say #12 for "Y" because on the UL1 the ESC came preset to 12 Degrees.

When I get everything organized, I'll list EVERYTHING, and document everything I do.

Not sure about the timing settings, but I believe all of these motors are Y Winds. Not sure of many RTR style motors, or even upgrade motors, that use "Delta" winds.

I'm NOT going to test each of these motors to it's ragged edge. I'm going to test them on a COMPARATIVE bases, as a couple or a few different load levels. You'll be able to see how they compare to current approved motors, and also how they compare to each other. You'll be able to see the better motors based on idle currents, etc..

The AquaCraft 60amp controller is set to 10 degrees.

Horizon says that the Dynamite 3650 2000kv 4 pole motor is a "D" wind.

The 4-Pole motor isn't the Dynamite 2000KV that comes standard in the BJ29, etc... That's a 6-Pole... And I don't really know what wind it is.

Nice find on the Info.
Sorry - I was told long ago that it was 12 degrees.

Pretty anxious to see how these pan out side by side

I recently heard about a club allowing a 4075 motor in P limited because the kv was within 10% of a 2030. Totally different animal. That's rated at 2400 watts. Think the 2030 is rated for 950 or something. Apples and cinder blocks. The 4075 motor wins of course. How could it not.

I get allowing other comparable motors at a club level but make sure they're comparable. Close at least. Or call your class something else like the Wisconsin guys did. No real confusion that way.

Just shows a clear and complete LACK of grasp on electrical motor understanding, and, frankly, the rules... ALL dimensions need to be considered for the motor to be allowed by the CD. It's pretty clear.


My "Thesis Statement" on what the outcome of this motor testing is going to show is: "The motors most appropriate to be included in the P-LTD Specifications are all 36-50 sized motors."

It is clear, when you get all thee side-by-side, that the TP3660-1950 and others in that size range are CONSIDERABLY more motor than any of the currently allowed P-LTD motors.

I didn't want to call them out specifically. I was hoping they would see this here.

Isn't the 2030 already 36-56?

Did you notice how small the rotor is inside the SSS can? Struck me as weird.

The CAN is that long... but when you actually take all these apart and measure, they are all around 30mm Stator length (that's 36-50 size).

Size DOES matter, but it's the size INSIDE the can, not the can itself, which should be obvious, but...

I recently tested a motor from a new company a 4082 1600kv, they said it was identical to a Leopard. After testing it didnt match up. I took it apart, less wire, lower weight. When asked they said oh, we will see what we can do. So I agree, whats on the outside is just that, only part of the equation.
