Looking for motor ideas

[DPeterson]

Looking for motor ideas to replace the current approved P-Limited motors.

We got a Midwest contingent of racers that run Electric, Nitro and Gas. Primarily Nitro and Gas. The ELectric is showing a little growth. The sore spot is the motor. We'll call it LSH, LSO and LS OPC.

Not looking for a debate. Not looking to race sanctions, nationals or for records. Decision to go this direction is final. Just carmalized my last 2 bran new 2030's.

So - looking for a quality motor to replace. Not looking to increase speed. We are thinking a 1900 KV. Along with this we are looking at a max prop diameter of say 46mm.

An American made or designed motor would be a plus. Same can size and bolt pattern would be good so we have little retrofitting to do, but not a deal breaker. Cost is relevent based on quality.

What's out there?

Doug, are you looking to replace the current motors, or add new ones that can be used as well?

[tlandauer]

Please forgive me as I know my place and I should not be making any comments here, but I have had good experience with the TP 3630 10D, 2100kv, I think anything above 2000kv, this might be a good alternative. The 11D is 1900kv btw. Motor is 36x60, bolt pattern is the same as current sactioned motor.
Just my $.02.

Hi Doby - Just looking for a good quality 1900 kv +/- motor to run in our spec boats. We are exiting the P-Limited arena.

tlandauer - the TP 11D 1900 sounds interesting, same bolt pattern is great. Is the 36x60 the same can size too?

Yes, the TP11D is the same size: 36x60

Doug, I'm with ya actually. We should consider talking about this as district since we tend to run in the same circles.

If we drop the 6 poles and go to 4 pole the wires from the can that are always the point of failure every single time will be larger and less prone to failure.

If we stayed around the 2000kv mark in a similar sized can to the existing spec we should/could be in good shape.

Tom and I are working on something but it's not American made. It will take us some time too. The motors we're looking at are inexpensive and the quality is pretty good. Similar to a TP. Retail is about the same as an AQ. Same size cans but only 4 pole and heavier wire. Don't have them in our mitts yet.

Why not the NEU 1410/2Y/SE
$99.00

The 1410/2Y/SE is designed as a lower cost version of our popular 14XX series motors. It has a little smaller rotor diameter rotor but to makeup for that the stator is a bit longer. The Kv for this motor is 1850 with a no-load current of 1.4 amps. Weight is 205 grams. Diameter is 36.5mm and is 58mm in length. The output shaft is 5mm. We are offering a limited time special on these motors of $99. This motor is a good match for the MidiFan running 6 or 7S and drawing 60-80 amps with thrust in the 70-90oz range. The 1410/2Y also will make a prop plane move right along too with a 8x5 prop and a 3S battery it will draw 50 amps and with 7x7 prop 45 amps.

Limited time my butt. If they knew we wanted them on a regular basis the price would most likely stay at $99 as it has been for over 9 months. Just sayin'

tlandauer - where do I find the TP11D?

The TFL SSS 3660 5.5D 1950kv motor might be worth a look.
They are on the TFL motor list but check with Monica as to whether they are still available.
Their 5D is 2140kv.
Although the SSS motors are 4 pole windings the rotors are 6 pole which adds about 20% more torque.
I use a few SSS motors & they certainly are good little powerhouses.

[T.S.Davis]

I know Doug isn't caring about the existing motor spec and for sure isn't willing to fight about that but I will..................... if TFL started selling their RTR boats with the 1950 motor then NAMBA would be forced to accommodate it. A club or district can write their own spec should they so choose.

SSS has a 2050kv too I believe. Somewhere in there. That's the avenue we were exploring. Realtively inexpensive. Tom has been running a couple all summer but not the wind we would want for a spec type thing.

Because I've heard every argument I'll save us one of them.

How do you know there wont just be manufacturing fluctuations in this new brand of motors that will be failures just like we've experienced to date? The answer is we don't. It's manufacturing. Crap happens. But if we choose a motor that's less impacted by those fluctuations their wont be as many failures. All theory of course. Those itty bitty wires on the AQ motors are the point of failure. We don't throw magnets. No spun bearings. It's always the same failure. Choose a motor that wont detonate if you pick up a weed or clip a turtle and have your sporty turn fin kicked up.

The trouble with my idea is that I've not got my hands on the motors I want to test so I don't know for sure what the wires would look like. The wires on the motors we've seen are larger but that may not be the case on the smaller SSS motors.

Where did you find this information? I've been looking for it everywhere.

[785boats]

I did read it in a spec sheet somewhere, but I can't find it. But it is also on the box that the motors are packaged in.

My apologies for not giving the links!

[DPeterson]

Thanks tlandauer.

You just might have kept some of us racing electrics.

What is your opinion on KV? 1900 or 2100? Not looking to increase speeds. Just want durability. I am under the impression the 2030's really only put out a kv closer to 1900. I am leaning 2100. Will probably pull the trigger on a few for testing. If they look promising I'll purchase a large quantity to get a volume discount and pass this along in my district.

USA, USA....

I threw a magnet in a 2030 AQ motor 2 years ago, nasty...
