btw here a pic of the inside of a plettenberg. looks kinda 'similar' to the neu.

Thanks, I figured the spec was unloaded. It required me to step up 2 teeth on the pinion from what i figured in the crt.5 to get the desired speed. It works well on 3s, and never even gets warm. So I figured more load would not bother it. Plus I want the c50 hacker 14l out of the max and in the hyper8 buggy for testing on 6s lipo.

I toasted a Kontronics FUN1800. The thing got hot faster than the feigaos. It got over 300 degrees F on its last run. Oops....

Amazingly it still runs, but the burning smell never went away.

Took it apart and it still looked OK, just smells funny. Its been sitting in the motor box for quite a while now. If anyone needs a pretty paperweight or good hard drive eraser I'll let it go cheap.

The only thing i don't like about those Plettenberg Maxximum/Bigmaxximum motors is their high KV. Those motors need good batteries and suck a lot of Amps (due to their high kv rating). But i red they can be wound differently at Plettenberg to get lower kvs. Other than that, they are one of the only motors truely built for offroad use.

i don't know how many A they really draw. your are right however on the very limited windings. but remember when those motors showed up. i can not date it exactly but when i made my first brushless savage in 2003 they were already there and quite common. so i guess they appeared around 2001 or 2002 or earlier? and what were the applications those times? mostly (3906) e maxxs running with 12 or 14 cells. a maxximum or bigmaxximum is perfect for such a setup of voltage and weight. by now things have developed and now converting truggies etc is common and the people have seen that high voltage setups are more efficient etc. especially due to the increasing use of lipos that made it more easily to go HV without too much weight. and so lower kv motors were needed and used. so plettenberg maybe should react to this with a lower kv bigbigmaxxium with around 1500rpmv.
when i started i got even recommendations of a C40 10L hacker for a savage.... and there were not few that used lehner basics in etc. of course there were also others like promod that already were with the big lehners and many cells. however it was not common to use HV setups with low kv motors at back then and i guess this is part of the reason why there are not more windings available.
