I want to see what this beast can do. Tested out my new recorder for a few minutes using my neu 1515/2.5D on 6S and it peaked at 107A. Eager to see the data on the 1100kV Medusa now. This is in my Hyper ST.

That thing is going to be insane. My 2000KV 80mm on 4s moves my ~14 pound Muggy around like it was nothing.

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?

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.

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 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.

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.

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?
