Castle 2200Kv or Medusa 80mm 2000Kv

[phibes]

Hi there,

im going to convert an 1/8-scaly truggy (Mantis). Since the 8s-ESCs are too expensive for me I decided to get the MMM. I wonder if the MMM-Set with 2200KV-motor or the MMM-ESC with a 80mm Medusa 2000Kv would be the better option. The Truggy will weight around 4.7kg and run on 6s. It will be used for bashing only.
I should rather be overpowered then underpowered.
I wonder if the larger diameter of the Castle means that it produces more torque than the longer and heavier Medusa. And how do they compare in terms of efficiancy?

many thanks

If you'd rather be overpowered than underpowered, go Castle.
If you want more torque, go Castle
If you want more efficiency, go Castle.

I believe that is all still opinion, and not based on facts. I would bet the Medusa would have better torque, perform better on 6s,and the efficiency would be very similar. I know that my 2 main bashing buddies each run the CC 2200 in E-revo's,I run a Medusa 60-2000,with a Medusa heatsink. We all vary our gearing,tires and cell counts depending on how we feel. But all said and done, performance, and temps are very close,whoever is geared for the fastest speed,wins. IMO if I was running the 80, my torque would be noticeably higher, and temps would drop. So, if I was just buying I would get the combo,for cost factor,but I think the Medusa is a very good choice if your looking for a single motor. But if your set on running 6s,I'd go with the 80-1600,probably the most efficient at that voltage.

Asheck - what cell count are you running the 36-60-2000 on in your e-REVO? What speed are you geared for and how are your temps? I'm trying to decide between the 60-1600 and 70-1600 for my e-REVO on 5s. I'm looking to get less torque than my 1515 neu 1650kv. The neu is awesome but I want something that isn't going to wheely the whole way around the track but I can still bash with!

I think Ascheck is right in that the efficiency and power between the Castle-Neu and Medusa 80mm will be probably very similar. The Medusa will have a *slightly* longer rotor, but the difference will be very small. All I know is that my Castle motor stays ice-cool (not literally lol...but hasn't hit over 130F).

However, the Castle motor is built much better for offroad use, IMO. Bigger bearings, and a much thicker/tougher casing. That the windings terminate inside the motor and are presoldered to nice, thick 10AWG wires makes things even easier. It's also sealed, so you won't get any rubbish inside. A word of warning though; The Castle motor on 6S will be utterly incredible! Good job you're bashing, as it'd be way too much for racing unless you have exceptional finger control.

Either of those motors can produce insane amounts of power and remain cool, but I'd go for the Castle personally. It's just built better.

I completely agree with these statements.

thanks for all the replys, i just thought the Medusa would be more powerful since it weights 60g more than the Castle-Neu.
So i think im going for the Castle-Set then and if it turns out as to aggressive i will use less cells or configure the throttle-response-curve. And if all that wont help i can still buy the Medusa later if i feel i need it, but i cannot get the Castle-Neu as cheap as i get it with the set ... so maybe i go that way.

Well darnint, my problem of not reading the posts rears its ugly head again. I didn't see the 80mm in there for some reason. Now that I see that, i'd have to say it would probably be a pretty close contest. I was thinking 70mm for some reason.

Asheck - what cell count are you running the 36-60-2000 on in your e-REVO? What speed are you geared for and how are your temps? I'm trying to decide between the 60-1600 and 70-1600 for my e-REVO on 5s. I'm looking to get less torque than my 1515 neu 1650kv. The neu is awesome but I want something that isn't going to wheely the whole way around the track but I can still bash with!

I run 4,5 and 6s.But I probably like 5s the best,but thats the hardest combo to come up with.Currently I'm geared 24/65 with Tamiya TNX5.2r tires.I try to keep gearing to low 40's on 4s,and high 40's on 5.My temps generally stay under 135, but are just a touch cooler on 5,then 4 ,I don't worry about temps to much unless I have it geared something silly. So IMO if your looking for lower torque,and plan on keeping gearing reasonable I think the 60 would be plenty.

I got a reply from Mike today. He has recomended the 70mm so that's what I'm gonna go with. He was running the 60-2000 in his but said that at the end of a 20 minute run he was at the high end of the safe temp zone. I have seen Mike race and as he said he is a very smooth driver and if he was on the edge I don't want to chance it. For helping to control wheelies he has recomended playing with the settings on the controller and my radio, specifically the throttle curve. Hopefully I be placing my order before the end of the week!!!

I'll second that, the 60mm isn't any good for racing.. I toasted one and I'm not a "bad" driver.. you need it geared really low to keep under temp in long mains. Holds up fine for a 3-5minute heat though. I'd say 70mm is the bottom of the scale, but you can snag Castle 2200kv motors for 150 why would you bother with the medusa? PS check the specs, the medusa 80mm will run hotter than the castle-neu, it cannot generate anywhere near as much torque.

Hard to find anything wrong with this post.

I've got an 80mm Medusa in my Muggy and it's an excellent motor but nothing compares to a Neu. The price difference between the 80mm and the CC Neu is negligible, you can get a CC Neu for $140-$150 and I got my 80mm for $135. Just get the CC Neu, they're a good motor.

I don't want the CC/Neu because it's a 2200kv motor! I'm running 5s and I don't want to gear down that much. Lower kv higher Voltage geared for the same speed is a more efficient setup. Also a small pinion and large spur that would be needed for the 2200kv on 5s isn't as efficient either. The closer the two gears are to the same size the less resistance there will be between the gears. My 1515 2.5D is 1650kv and I'm very happy with it, a little less power wouldn't be bad. A 1600kv Medusa is the closest I can get to this without shelling out another $260. I already have a 36-50-4800 in my crt.5 and the motor is awesome, I expect larger motors will be of the same quality.

[Raze ST Truggy]

I have both the CC2200 and a 80mm 1600kv Medusa and an MMM for both. I was thinking that the medusa was better suited for the muggy, but after reading this thread I'm not sure.

What do you guy's think is a better combo for a muggy, and since I'm asking which for my Raze ST Truggy? Thanks

Sorry if this is a hyjack.

I don't own any 1/8 scale motors yet BUT I feel the same way you do.

On paper 2200kv is too much, especially since I plan on running 6s. If CC/Neu offered a 1600kv or thereabouts then I think it'd be a stronger argument. But as it stands, on paper, the 1600kv Medusa seems like a much better fit for 6s.
