e-maxx 3905 motor question

[Jason]

do you think this motor would fit the stock e-maxx motor mount ? since it has large diameters ..

Well, all 1500 series have a Dia. of 1.53". Yes, it will fit with the stock motor mount. You will find that a number of people here have Neu 1500 series in their emaxx's.

finaly im going to use a 20t pinion I forget the maxx are 32p.

and for the e-maxx does the driveshaft diff and tranny last a long time ? on my slash @ 3s I will destroy driveshaft and yokes so much fast

Yes, the emaxx is brushless ready. The drive shafts occasionally brake and that is normal unless you have steel ones. I am putting together a VXL slash right now, how often does yours break?

[Jason]

the driveshaft and yokes on the slash are not so durable @ 3s ... you will need spares for sure im currently using the stampede steel yokes still going strong and I tried too jato driveshaft plastic on the slash and still the same then the stock nothing would work better them the FLM CVD for the slash is the way to go for 3s & more ...

I changed my mind I bought a e-revo instead of e-maxx the wheel hex are 14mm right what about the stock tire diameters ? do you think the neu 1509 2.5d 2700kv would push it without any troubles on 4s with mamba max esc also ? and does it fit on the stock revo motor mount since its larger .. ?

The stock revo mount is the same size as the emaxx's. I would suggest getting a single motor plate @ cover for it. Again, yes it will be able to roll it forward but a MM and a 1509 are not a good choice for large trucks like these. If you have the $$$ then I would purchase a MMM combo or with a Tekno Nue then it will fly with no problems. If you do chose the MM with a 1509, watch the temps carefully. Since you are interested in the MM esc in a revo, take a look at this:
