Don't be bummed Terry, every man has his price..... for you we all know two bags of gummy bears, and a bag of double bubble, and your bought and payed for.

Cheers, Jay.

I've bought Terry for even less...

Oh sure one doughnut and now you own me!? Yer not the boss of me.

Just got notification that the 36x50 TP motor I ordered is on the way.

Once it gets here I'll start testing on the motors I have here.

Hoping to get anot her Leopard or two and some SSS motors to try, but I'll proceed with what I have. That may establish some baseline parameters to help guide us.

any updates

We're hard at work prepping for the November SAWs at Legg. Probably not going to see a lot of effort on this until after the SAWs. Darin has more important things to do, breaking 80mph on 1 cell being the most important.

Hmmm... Doing some more searching...

Here is an interesting consideration from Neu that might fit.

It's 36mm x 57mm, 205g, 1850KV.

Will have to test to know:

http://neumotors.cartloom.com/shop/item/25324

Here is the description:

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.

I have one of these motors in my possession
was trying to test it last month but did not get around to it yet
the motor is a little smaller for most coolers but the Proboat 1500kv one fit perfectly

Thank you for your hard work Darin! Several times I almost bought one of the NEU's but, balked. I'll test the SK3-1900kv motor I have.

----

The SK3 can't be taken apart unless people know more than me. I can still measure the rotor length and field length.

Turnigy SK3-1900kv

Rotor length 39.6mm

Winding length 46mm

4 poles

D wind

35.8mm Can OD

60mm exterior Length

This motor is packed with copper compared to an AQ 2030, 1800 or PB motors I've had.

This motor I did get to test in my JAE last month and felt as though it did not have the same power or speed as the AQ 1800kv motor

pictures are a pain to upload or I would post some

Good find - me wants one. Hmmmm...

Outrunner only unfortunately. And 5 kg of thrust restricts the power level for FE motors. A Neu 1521/1.5D on 4S will develop 5.5 kg at 200 amps. A Neu 1527/1Y on 6S produces 6.4 kg at 150 amps. Cool idea for smaller motors and lower cell counts.

yep... ah well...

Darin has more important things to do, breaking 80mph on 1 cell being the most important.

I have been putting my test platform to work a bit, in this regard... You know, just to verify that it's going to be up to the task...

I'm thinking that pulling 385-Amps for 5-6 Second pulls on my 1-Cell setup pretty much proves the stand will hold up.

Should hold up to the P-LTD stuff.

In that regard, I got word that there are a few more motor options coming my way. After we get back from the November SAW event in LA, I'll put a solid effort into some testing of these motors and will provide all the data.

[Brushless55]

I have a few



Much more copper
