It is?

Where can one find a new rotor for a Plett?

Sorry to hear...a sad day. One of the icons is dead.

Contact bl-power, he offered to get me one since he is in Germany, and ship it over. Much cheaper than trying to buy directly from plett while you are in the US.

I hope my big maxx stays together, plan to run 5s with it in something...

Candyman is oldschool, he'll be old and grey before he goes lipo

If the magnet is shot, chances are the windings may be a little bit toasted too- open her up and take a peak inside (it'll smell like an ashtray if the insulation on the windings is done for).

If by some miracle the windings are still okay, then a new rotor would be worth while.

Curious as to the esc settings you were using that cooked the PLett- timing, punch and start power can make a big difference to the temps...

If your thought is that the motor is toast, then why not send it back to Plettenberg and let them do an estimate of referbishing it for you. At least you can give it a try. If the cost is too much for you, then let em keep it.

you'll be ok as your running the schulze, I was running 18 cells, so equivalent of 6s, the speedo used to overheat and shutdown after 3/4 minutes if I was pushing it. I got the MMM which didnt shutdown, however I didnt notice the motor temperature, didnt occur to me really.......... i suck. Anyway, im trawling the internet for a 2nd hand Nue failing that i'll have to buy a new nue.

Those would have to be very very poor lipos, and some miracle NiMHs.

Under load, 18 cells is like 5S, if you're lucky.

Darn that does suck! I just sold my Bigmaxximum for a new Neu motor and no complaints at all!

ANGRY-ALIEN · 08.01.2009, 10:47 AM

I think the truck deserves a new Bigmaxximum or the new rotor... I just can imagine it with another motor in there. Both the looks and the sound that thing made won't be the same with Neu...
I'm not dissing Neu, but that truck is an icon, which saw many changes and improvements that were made to it over the years and that pletts motor made it look even better.

If the windings are toasted too, a new rotor wont do much good on its own, but then the cost to replace both would probably be more than its worth.

I have a question though, what the inside diameter of the can, and the wall thickness (rear endbell area once the fan unit is removed)? It might be possible to bore out the PLett on a lathe and turn it into a heatsink for a 36mm motor, like a neu 1415, lehner or my medusa perhaps...

What a killer idea! Then you could maintain the look like Alien said.

LOL, I was thinking the same thing...

To be honest with the bigmaxximum at 2150kv it was always a little over geared, I fitted a 56 spur with a 13 pinion but any lower and it tore the teeth off the spur. It will be good to go to a 1515 2.5D 1650kv and have a bit more scope to gear it.

Candyman2 · 08.03.2009, 04:09 AM

Some NIMH's are crap, i agree, I got some LRP 4600's recently and they didnt hold any sort of voltage under load, but the IB4200's are still the best by miles, they give out huge amps under load. My rule of thumb is, if it'll flip the truck on its roof, it has enough punch.
