Hahaha, good to hear. I can already hear my wallet screaming.
What was that old saying, you won't break anything if you don't hit anything. Hopefully I can do that.


Not bloody likely.

What is your wallet screaming? Bloody murder from having so much money taken out of it? Or excitment?

Do you think 80mm is too much for the muggy?
Because I didn't want to wait for the larger motors, I got a 60mm 1300kv medusa for my muggy. Only had one run on 8s so far, but it did really well. I'm thinking the 70mm 1200kv might be just right for the muggy on 8s.

A bit of both, but swinging more towards the former.

Well I'll say this. Comparing a tekno NEU 1515/1/Y/F (2200kv) to the Medusa 36-60-2000kv. The Medusa's must not be very efficient motors. I had the NEU in an SC8, geared 13/46 on 5s and the NEU never got hot, 110 at best. I have the Medusa in my D8 buggy, geared 13/48 on 5s and it gets real hot real quick. The SC8 has diff gearing of 43/10, the D8 also uses 43/10. The D8 and the SC8 also had the same size tires, same set of tires for that matter.

So I went ahead and ordered a NEU 1512/2.5/D/F for the buggy and the Medusa will go in my basher/Corr truck project.

it gets real hot real quick.

Could you be a little more specific?Mine runs nice and cool in an Erevo,rarely tops 140.I run 4,5, and 6s,sometimes geared for 60+ mph.But I have heard of a few others whose ran hot,I have to wonder if there is a little inconsistency.

Undergeared? Running the numbers in the calc shows a top speed of only about 30mph. IMO an 18t pinion would be a better choice for about 40mph.

I like how it runs on 4s. It's very powerful and even with the soft start cranked up on my MGM it'll launch like a scalded dog. The 70mm would be fine, but I like that extra bit of power I've still got the massive stock tires on mine (and I actually like them a lot) so that needs more power to move around. If you are going to an MT (Revo, Savvy, etc.) sized tire the 70 should be fine.

I E-Mailed Mike about getting heatsink clamps made for these new motors and he said they will be coming out (didn't even give a hint at when though) but he said that with the motor plate on the front the 74mm XL one will fit the 70mm motor.

The Neu is 15mm longer and 4mm wider, that's where it gets it's torque. Compare a 70mm MedUsa to the Neu and it'll be closer.

I too have the stock tire/wheel combo. Only mods I did to the muggy are rcm batt.tray, rcm motor mount, steering mod, single servo tray, mud guards. I think there might me some power advantage when you run a hv setup. Also 4s 2000 kv =30.000rpm and 8s 1200kv = 35000 rpm.

Would it be safe to say that a 70mm on 8s has as much power as a 80mm on 4s?

The 80mm will have more torque provided that your ESC and batts are capable of putting out enough amperage. It would be interesting to put my 70mm (2000KV) motor in my Muggy with the same pinion and see what kind of difference there would be. I ran a 24T pinion at first just to see how insane it could get but I'm running a more conservative 16T now. If I can get a cameraman I'll try to get some video of it, it powerslides very nicely and busts through several inches of snow. As long as I don't high-center it on the snow it can blow through.

EDIT: Did you do anything to the Center Diff? The first thing I did after stripping the nitro crap off when I bought mine was pull the CD and put 30K fluid in it. I can still wheelie and it balloons the front wheels as it does it but it really helps to make it 4wd instead of FWD If you get the 80mm you'll probably also want to oil up the front diff, I can unload mine pretty easily and will probably get some 10K for it to hook up through on-power cornering.

I put 30k in the center, 10k in front an 7k in the rear. I also have a robinson racing 48spur in the center. I'm thinking of replacing that one with a 45t losi 8ight spur, or just the stock 46.

I was geard pretty conservative on my first run, 11/48. That's because I wasn't sure how the 60mm would handle the muggy. Larger pinions are on the way. Right now I have my muggy set up with a mega acn 22/45/2 and am wating for the outside temps to rise (freezing here right now, and already broke rear arms bc of that and my crappy driving).

EDIT: I also replaced the plastic diff housings with losi alu ones.

[Unsullied_Spy]

Why the RRP spur? The stock one is free and seems tough as nails so far. Your diff setup should handle the power nicely. It's freezing here too, but that has never stopped me before I finally managed to break my tricked-out Rustler the other night...-40 degrees and a full speed impact with a car trailer and all I broke was a camber link

As you can tell I wasn't burdened with an over-abundance of common sense, I love to run my RCs and I'm not letting mother nature tell me no

I bought a used muggy, and the spur looked pretty beat up. As I wanted to start conservatively, I got the RR spur. Wasn't sure how heavy the muggy would be after the conversion to brushless. But now I know, and am going back to stock as soon as I get a new spur.

I guess it's possible. I have a 16 tooth, will try 16/48 and play with the timing. If the company is suggesting 8-15 degree timing then I'll put the MMM at "Normal" and try that.

Maybe these motors are absolute beasts and can handle just about anything you throw at them, except undergearing.

[slash_48]

What kind of temp are you guy getting on the ecs. I have the medusa 36-50 4800 the motor hasn't got above 90 but my mamba max esc. gets 135 to 150. My max amp 2s 6500 battery only get about 85. This is in a slash geared 23/83. Very impressed with this motor.
