Which Medusa motor for E-Revo?
 

I am going to get a E-revo and a medusa motor. (Got a MM ESC)
But which medusa ?

3300 ?
2200 ?
2000 ?

And should I get a 3s 8000mah lipo or two 2s 8000mah lipos?

Thats my only question before I order everything, and are ready to go electric monster!

the 3300kv should not be considered, it depends on what voltage you will be running...with both the 2200 and 2000 you could run both on 4 and 5s and if you run 6s the 1600kv model

RCM Mike had the 60mm 2000kv in his Erevo this weekend and it looked pretty good. Stayed cool until it broke the revo's driveshaft. Too bad as I wanted to get a better view of it. Not sure if he had on 4 or 5s tho. It was on a MM as well.

So which medusa should I go with then ?
2200kv and 2 x 2s lipos ?

if you are running 4s

the 2200 will give you more speed but less runtime and potentially a hotter motor...if you plan on ever going higher in voltage I would get the 2000

so which motor will give me the longer runtimes ?

as a rule a lower KV gives you longer the run times and slower speeds, but you can make up the slower speeds by running more voltage

I like to run a higher voltage/lower KV in my setups but that becomes more expensive

when you run higher voltage you get less of an amp draw from the motor and this increases runtime and decreases heat

Then I should get the 2000kv motor and 2 x 2s lipos ?

that would be good and if you feel it is too slow you can gear up but that would put extra resistance against the motor and this can cause heat buildup and reduced run time, but with a decent motor like a Medusa it may not be an issue...there is a give and take with BL setups

so what runtime will I get with that setup ?

with my setup on 6s I get 30 mins, so my guess would be 15 mins if your packs have a 5000 mah capacity

I have 8000 mah and I was expecting an hour!!

Depends on driving style and motor used and how you have your truck geared. I tried the medusa on my maxx but the motor got too hot for my liking bordering on 175-180. I ran 6s with the 36-60-1500 medusa. They are good motors and have worked for some in an MT but if you are in a hot climate like me I do not recommend using them. Now when the 70mm version comes out all should be fine.

with the medusa 2200, MM esc and 2 x TrueRC 15c 2s 8000mah lipos, what speed and runtime will I get ?

with stock gearing expect speeds 40-45 mph and runtime around 30 mins and as TeaxasSP said it also depends on driving style, you wont go wrong with either of the setups...(2000,2200)
