New motor in a emaxx questions

[Oldblue72]

So I was putting a emaxx together off of spare parts and the only motor I have is a 1/10 scale 4600 toro and esc. Runs great on a 3 cell doing back flips and still under 100 degrees. My question is besides heat what kills brushless motors. As long as temps are good is there anything else I have to worry about?

Over reving a motor and bearing failure are two more

[Oldblue72]

So not a good idea to run 3 cell ?

[50togo]

Its a mid size kv motor on 3s shouldn't max out the motor but I would want to.know its max rpm because you will turn just over 50k

[Oldblue72]

Where can I find its Max rpm? Have it geared at 11/68 do you think it will hit 50000 rpm geared that low

[50togo]

That is geared way too low! Depending on your tires you will hit 50000 quite quickly
Sometimes from the specs of the motor
Now is see! 3s is not recommended http://www.ckhobby.com/shop/?control...product_id=386
Short course motor

I have series 40 trenchers that's why I went so low but will defiantly gear it up thanks for all the help

[50togo]

Yep.
Some taller gearing will wake it up!

Finally quit being cheap and got a 2200 Kv toro motor and esc went from not having enough power to stupid power lol

[50togo]

glad it worked out!
what batteries are you using

[Oldblue72]

One 4 cell 30 c pack
