motor recommendations

[08gtrking]

EMS was $26 for 2 motors delivered to me. Guy's,...........be carefull here on these topics referencing other motor vendors. Steve/OSE is a business. He is going to carry these motors soon. PM info to others asking motor costs. Its not fair for OSE to provide and pay for this forum and then advertise who under cuts him on his very own pages.

I know it would piss me off if I ran a free web site and business was being redirected in public view for all to see. Have some sensitivity at least.

i only posted the other site because he didn`t have that motor yet he only had the smaller version that was the only one i found if not i would have posted his motor.

I knew the price that was given me 6 weeks ago was to much
My guess was $130s or so

[forescott]

The 56xx series motors are more than 80bucks
I've seen them priced at $180-$210

I think he said 80-bucks cheaper, not 80-bucks sale price.

[08gtrking]

how would i make water cooling jaket for this motor?

OSE should have some shortly if you can wait.

BTW, here you go. http://www.offshoreelectrics.com/pro...?prod=leo-5692

John

Yep.............and $149, plus a very minimal shipping price and to your door in 3 days

OR............$136, higher shipping price for standard shipping..........WAY longer to get it..........or Higher dollar EMS and still longer to get it.............

No brainer..........................and he backs up his product better than anyone..........responds to e-mails...........etc..............

You guys think 1340kv on 6s will get him 60mph? I think thats a good combo and would power the boat well but I think he might need to up the cell count a bit to get that kind of speed out of a 36" boat...

go 60+ ,what cell count you thinkin about

[keithbradley]

I think others would be a lot more qualified to answer what would be correct. I am just thinking that everything I've ever got that kind of speed out of Ive had to turn more rpm than that, but I could be wrong.

[forescott]

That motor doesn't need more rpm, because it should have enough torque to spin a huuge prop! That is where you're speed will come from.

[08gtrking]

Ok thanks so thats going to be my set up now i need to know esc and hardware
i was thinking 180amp esc and this hardware http://www.offshoreelectrics.com/pro...prod=ose-80085

Not on 6S right off the bat. On 7S he has more rpm and thats most likely where he might have to settle. 8S is just about suicide with that motor as amp spikes would almost certainly get over 300 no problem. But on 6S, and taking the time to dial in the hull, perfect a prop, there is no reason 60's is not possible. The gas/nitro folks are doing it with 23 to 27k rpm motors. No reason us FE types cannot duplicate such on 29k.

So if I was to get a 1090KV version, 6S would be enough with 24,200 rpm... 22.2 x1090 = 24,198 rpm...

Or would I be better with 7S?

Please let me know, it is for the 40" DF clone mono. ... Using Monster 2000 esc....

[forescott]

It seems like that would be enough rpm with a big prop. Remember that these motors claim to be 90% efficient, so you have to subtract 10% right away plus anywhere from 10-20% for slip. Also remember that that number is unloaded rpm. Without knowing how this motor will perform, I would stay on the higher rpm side. Either 7s or the 1340kv version on 6s.

Here is a link for the ose top speed page where you can play with the numbers to get a good speed estimate for you're build. http://www.offshoreelectrics.com/conversion.htm

[ray schrauwen]

O.k., thanks! What prop can you suggest to start with and beyond...?

[ray schrauwen]

My gut is telling me to go 8S on 1090Kv for some reason?, thats alot of power though...

Need to do allot of thinking because I don't want to get the wrong batch of cells...

9s on my 1020kv in my DF40 runs well.

[ray schrauwen]

What props can you turn?

[Brushless55]

9s on my 1020kv in my DF40 runs well.

Wow, that's got to be a monster!

[08gtrking]

What do you think of the 1340 kv on8s

[ray schrauwen]

Steve's 1090kv's are selling faster so far.

[forescott]

The 1090 is a more 8s friendly motor.

[forescott]

I would run the 1090 on 6s with 1/4" drive components and a monster prop.

[ray schrauwen]

Thats odd, is one post somewhat contradictory to the other?

I've got 1/4" hardware, step down stub to3/16", (thanks Steve!)

Just can't decide.... 6,7 or, 8S ?

[forescott]

I meant 8s is better suited for the 1090 as opposed to the 1340. I like 4 to 6s setups myself. That statement was in response to 08gtrking. Guess I shoulda quoted him.

[ray schrauwen]

Thats more like it.

Yes but, I want to nip at some other more expensive Open Mono's heels.

i don`t get it if i run 8s on the 1090kv motor it going torun as fast as the 1340 on 6s?
