i have one of these as well and its 4 pole

I generally agree with you... but what you said about gearing lower for 2 pole motors to get the torque advantage. Not true, when you have 3 times the torque you 'need' from these motors as it is. :wink::whistle:

Then you might be able to use a smaller motor and save yourself some weight. :)

hey, I never said we don't 'want' all that power! :mdr::yipi:

Plettenbergs quality is second to none and are easily the same quality as Neu's or Lehners if not even a little better , I have all three in a variety of sizes . The pletts are enormously powerful and have huge torque for there size . the big maximum is based on the plett 220 frame, Neu's on the other hand are probably the most efficient out of the three............:yes:

hi

yes the quality of the plettenberg is above reproach. we run severeal of those motors here only in very dirty offroad applications. i have one here that is used all-season since autumn 2003 with zero issues. still no play on the bearings or anything. it runs like on the first day. they are designed for offroad applications and need no modifications for that like others do.

so i'm still considering either a BM or a 1515/1y. Which would be a better choice if i was to run on 6s??

I know that the BM's max rpm is upto 70,000, whereas the Neu's is only 60,000. Would that play much of a part?

thanks

I doubt many gear trains would take that level of beating for any length of time

true, but i think mine would hold up for a bit longer than most :whistle:

so, any input on the motor situation?

thanks
jordan

the two motors are both like 2200 rpmv.
maybe with 6s you want to go with a lower rpm/v motor ( in the range of 1500 rpmv). btw the missing availability of many different windings is the biggest (and maybe only) drawback of the plettenberg.
but i may be wrong and that NEU and/or the bigmaxx run good on 6s. it seems to me you go in a rather high rpm range. i guess correct gearing would be important.

Why not just run 4s?

yeh 4s will be pretty fast, i guess :lol: nah, i'm just going for super insane crazy!!

I think i'll go with the pletty, primarily because on the website it says that the motor can handle 6s in a savage. Whereas i'm not to sure if the 1515/1y will be able to handle 6s for long amounts of time without something going wrong.

How well do the pletts run on the quark monster pro? Anyone know? How does the BigMaxximum compare to the Neu 1521 series?

where did you see that statement?

plettenberg runs good on the quark.

I guess it doesn't directly 'state' it. But check out the table down the bottom of the page.

I'm looking at various 'bigger' brushless motors now, similar to a lehner 2240, but not that exact motor as its WAY to expensive, 300 euros :gasp: What Neu's are the equivalent of such motors, would it be the 1521 or 1527 series?

Looking at it, probably the best to run on 6s would be the 1521/1y or the 1521/1.5D. I know these motors produce bucketloads of torque, but do they still give good top end speed? On Brian's calculator the 1521/1y on 6s would only hit 37mph, is that accurate?

Enter Front/Rear Differential Gear Ratio: UE 1/8 scale
Enter Transmission Gear Ratio: E-maxx 2nd gear

sorry for all the questions, i'm a newb at these larger motors :oops:
