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

[Darin Jordan]

Darin,

What about the 4 and 6 pole versions of the new Dynamite 2000kv motors?

The 4-Pole version is a smaller motor, designed for their 2S/3S boats (Shockwave 26).

The new 2000KV 6-Pole could be considered for adding to the list. It fits the specs.

We're lined up here in Az to test this season, which starts in Oct. By the Winter Warmups I bet most/all of the Az contingent will have enough info to have a productive conversation about test results.

No offense, (and assuming the Dynamite motor just mentioned is a ProBoat motor), is anyone else concerned about their past production run history? It's spotty at best and I don't think I can support any more national rule ink just for them.

Hence why no additional RTR motors have been included on any of my proposed motor suggestion lists.

Guys who care:

Thus far, we've seemed to agree on considering TP, Leopard, and SSS motors.

Are there ANY OTHER MOTORS in the 3658 or 3660, 4-Pole sizes, with 1500, 1800, and 2000 Offerings, that should be considered? Brands?

I've looked around and these three seem to be a reasonable bunch.

Please list any others that should be looked at.

For the record, TFL makes the Pursuit, and I believe they supply HobbyKing with them, so I suspect that that Black motor in that kit is an SSS motor.

I would prefer not to have 4 brands..i think it needs to be limited to the current selection and maybe 2 more manufactures..but that's my opinion..at least to start with

[Darin Jordan]

Current list only has three new manufacturers.

[rayzerdesigns]

correct..im saying maybe start with 2..manufacturers that is

Awwww ... well, two, three, I'm not sure it's going to matter as long as the offerings are similar between them.

Picked 3 because that's what David N. Suggested.

I'd go with 4, given the option, but finding that brand seems to be tougher.

Given this path, you wouldn't have reason to revise or update the list for some time.

Imagine that? ;-)

More news...

TFL has added a 1500KV option to their 3660 SSS motor line. Monica sent me the specs this morning:

So, for the purposes of this discussion, assuming no one else has any suggestions for 36x60 sized motors to consider that 1) won't "break the bank", and 2) won't out-perform all those on this list, here is what an "Approved Motor List" might look like in it's entirety:

Guess the next steps would be to gather some real-world numbers?

"On the water testing" only goes so far with me. TOO many variables involved. I'd prefer to see actual controlled test data, measuring actual KV, Idle Currents, KV drop under load, etc., to get a measure of the motors actual performance and efficiency.

I will try to get a couple of the motors on the list, perhaps just one sample of each in the same KV range, and do some bench testing with my "home-grown" test bench. Similar to like what I've provided for the current crop of P-LTD motors. The data seems to fit the performance.

I'll see if I can get these samples here soon.

If anyone else has the ability to get some real-numbers, please feel free to join in.

haha Book it dano!

This is the lazy route I think but it would buy us another 5 years maybe and guys could stop whining about AQ this and Proboat that. All of course providing that the combination of all these work okay together.

I'm still not sure we even need the TFL motors on there. Currently they're hard to get as nobody stocks them and getting product from TFL can be .................clunky. Even for distributors. At times.

I'm not sure it would be Feng shui to just have two manufacturers... things look at work better in 3's... Triangles are stronger, after all...

Like I said above, I'd have 4 on the list if we could come up with one more that's on par. I'd hate to have it just two... That's what we have now, and as soon as ONE is missing, you have a mess.

At the very basics... it's not going to HURT having that additional manufacturer listed.

Seeing as the Leopard and the SSS motors are likely just copies of each other... I see minimal risk.

Not Lazy... you have to use the correct "Brian-ism"... BAND-AIDE...

BUT, you are right... this should solidify the power structure for quite some time.

[longballlumber]

Soooo.... All along the number one objective/intent of this conversation (future of P-Limited) was to put enough motors on a list so we don’t need to have this conversation anytime soon. Evidently 5-6 years wasn’t enough? Maybe a better statement would: 1# - Provide enough approved motor options in the case of manufacturing/quality flaws prevent constant motor performance from production batch to production batch.

#2 – Cost

#3 – Balance of performance – (I find this almost laughable) 17 different motors doesn’t promote “parity”

#4 – ease of entry – I don’t think options necessary help newcomers. They won’t know what to buy.

This is exactly why I kept asking what the intent was. Am I the only one that is seeing this????

[T.S.Davis]

Only 13 of those are available to purchase.

Show us the way. This is still an open conversation. There is no proposal or anything etched in stone. We were talking about having guys hunt down their own motors based on dims and weight a couple pages ago.

No attitude intended BTW. I would still be on board with a single motor.

On the topic of "parity"... Riddle me this... ONE motor...

You want to run your DF26... Someone else wants to run their 32" Pursuit...

Where is the "parity" with a single motor??

Single-Hull classes... is that what we want? (rhetorical... I sure don't)

The number of motors listed is simply trying to match the KVs we currently have available, which is a formula we all seemed to agree made for a good selection of motors.
