MMM + 2650 combo vs MMM + medusa combo

[shaunjohnson]

which is better/cheaper?

i know the 2650 is just a machine would NEU and that neu's kick nuts.
but can i get the same or similar performance for the same price with a medusa?

running 4s lipo btw.

Well you can get the MMM combos for ~$280 USD at most places. If you bought a MMM from Mike ($165 USD) and a medusa 80mm from Medusa ($145 USD) That's $300 vs $300. So, same price, but I'd opt for the medusa because the Kv options seem better to me. The 2000kv would be a monster on 4s!

the 70 or 80mm cans??
it's a revo conversion and i want power to push around weight if it gets heavier (i hope not) as it gets covered in mud at the track

1) The MMM motors are hand wound, neu-based designs; they are somewhat different inside though, so no direct comparison can be drawn.

2) The 2650kv motor is equal to a 1512 in terms of size, and the 2200kv motor is equal to a 1515 1y, though it is smaller diamter I believe.

3) The 70mm Medusas would be equal to something around a 1512-1515 , and the 80mm Medusa are roughly 1515-1521 equivelants.

4) For a ~9-10lb truck, I'd go for the 2200kv MMM or the 80mm Medusa for best results and to save having to upgrade if your truck puts on weight in the future.

I would strongly suggest reading the threads in the BL section on the Medusa motors, and the CC section that talks about their motor combos; much info to be had.

I am very excited about the new motors that are coming out now.

Both the Castle Motors AND the new Medusa Motors promise to deliver loads of power.

I do intend to get one of the new Castle Motors, but I already have the MMM. I will probably wait until I can just get the motor. Money's kinda tight with Christmas here.

On the Medusa subject, I am VERY impressed with their motors.

I am running a 36-60-1500kv in an E Revo geared 18/40 with Mod 1 gears. It can handle whatever I want to throw at it in terms of voltage. Anywhere from 4S to 6S is fine. 4S is what I run most of the time, but 5S is alot of fun with 6S just being insane.

I have just acquired a 36-60-2000kv Medusa and can't wait to install it. I'm waiting on a Monster GT spur from the bay that is 52 tooth Mod 1. This will give me lots of gearing options.

The 70mm and 80mm cans from Medusa have yet to hit the market. If Medusa Quality remains the same as their shorter versions, I see them as being VERY Competitive with Castle, and even with Neu.

More on this later, as I intend to get the 70mm and 80mm Medusa Motors also.

They are all kicking in my opinion though.

80mm.

thanks guys

just to double check...
i wanna run 4s (my charger can do 5s but it's a chinese copy charger so i dont wanna push it (a good copy though)) so is 2200kv medusa (80mm) gonna be high enough kv's?

my friend had a revo conversion, he hwas running a feigao 9XL on only 3s and cooked it when he geared it up to get some decent speed out of it.

now i dont wanna have to gear up due to a motor with too little RPM's.
i have my rustler for uber speed so this revo has to be around 45-50mph speed wize.

heat is BAD and the last thing i wanna do is use fans (i have a CC bec but i don wanna load it up too much with all of the revo's break servo's etc)
so i wanna keep the heat down (happy to use non-fan assisted heatsinks) and the speed around 45-50mph on 4s.

i have access to a couple of 8k 3s packs so on the rare occasion i may hit the 6s but not for long.


i was gonna go with hte 2650 from castle but now i'm kinda leaning towards a 2200kv 80mm medusa, you guys either have to push me over to medusa or stop me leaning and push me to castle-neu motors.
thanks guys,

Yes, 2200 will be good for 4s. Make sure you get some good batteries though, most likely your setup will pull a lot of amps.

thanks again guys.
i was looking at running rhino-zippy lipo's.
4900mah
http://www.hobbycity.com/hobbycity/s...idProduct=7299
was planning to run them in parrelel to get 9800mah (i think they are 5000mah cells though but u cant use the last few mah anyway otherwie the voltage drops too low)

so that gives me 196A continuous.
i know it cant draw this much before something goes poof so i should be right with that setup?
and i also get HUGE long runtime to boot
and i was also thinking that i could pissibly run them as a single pack to keep weight down in the 5 min heats.
will this setup (MMM + medusa 2200kv 80mm, revo 3.3 w/ stock shifting tranny) run on a mere 98A continuous?
the nitro guys already took a look at my rustler in hte 1 hour mains (i was racing it in hte 1/8th MT class as that's the only way it can fit in lol)

and the looks on their faces were kinda like...
lets hope my setup comes together

thanks again guys,

I like it when people try to correct me, but Im the one who was right to begin with, lol. In addition, there was nothing wrong with my diction, punctuation or terminology (A & B at GCSE level English).

[BL_RV0]

Showoff.

[suicideneil]

You say that like its a bad thing...
