Neu vs Medusa motor temps

[ilpufxit]

I finally got a chance to run a side by side comparison of motors.

My local track opened yesterday. I ran a full pack in my 8ight-T with a 70mm 2000 kv Medusa. It came off the track at 190F, the MMM was about 110F and the Zippy FlightMax 5000 pack was about 100F.

Same everything, swap in the identical but charged pack, now with Neu 1515 2.5d. The run was longer by several laps but I wasn't timing it. Came off the track at 110F, MMM was about 80F and the Zippy was 100F.

The Medusa gives more torque and higher top speeds (based on my impression only) but clearly sacrifices a lot of efficiency to heat. So far, it seems to handle the heat though, I've run it up to 190F, even 200F a few times with no perceptible loss of performance.

Now that I've seen the difference for myself, I'm fully sold on the value of the Neu motors. Not cheap, but worth the extra. One thing I would mention is that if you're running a steel spur gear, you can expect to need a new front armature bearing periodically. Do yourself a favour and order a couple before you need them.

I'm going to get back to work now.
