Tekno Neu 2200kv vs Castle Neu 2200kv

This is a neat discussion and I think it all comes down to what the end user is willing to trade in return for desired performance.

I have a Neu 1515 2.5d, a Tekno Neu 1515 2d, and a Medussa 36-60-1600.

They all seem very stout on 6s and will only run hot if I decide to use gearing that's way too high. I'm sure we all know that the Neu's 15xx series are a bit larger (more torque as well) than the Medussa 36-60-xx series motors. This extra "umph" gives more range for gearing selection before the motor runs too hot.

I use the 1515 2.5d in my heaviest car (Muggy), 15152d in my converted Revo, and the 36-60-1600 in my Hyper 8. After fooling around with MMM esc and radio throttle curve settings to my liking, takeoff's are brisk without being too violent on drivetrain parts. Even when bashing in wide open spaces, I've found that gearing them too high only results in speeds that are near un-controllable and a motor that heats up quickly.

So.. I although I haven't tried a Castle Motor yet, from what I'm reading it sounds like it falls along the lines of the motors I have now. In a proper set-up, I think all would do just fine and run cool.

Since I don't have any heat issues with 6s 5000mah packs, I don't have to mount my Tekno Neu to the chassis and risk pinion/spurr misalignment due to chassis flex. I use Mike's mounts instead and call it a day.

Higher voltage, lower kv-rated motors will draw less current for the same power output.
If I were to custom order a set-up, I'd go with something along the lines of 10s or even 12s with a 1000kv motor. Yes, the batteries would cost more but hopefully those expenses will decrease the more battery technology increases. Imagine being able to run a 45-minute main without changing batts and having no heat issues.

Well, I don't have a Tekno Neu, but I just received my Castle Neu and wow I'm impressed! :D Running the same 4s2p A123 packs in my ST-RR with 15/50 gearing, the CC Neu doesn't even get above ambient temp.

In comparison to my 2084kv Feigao 8XL which was getting up to 60 degrees Celcius in about 2 minutes at this setup.

I expected the CC Neu to be better, but this was really unexpected :D

the 2200kv is a 90% efficient motor. that means energy produces power, not heat. they are great motors. other, less efficient, motors waste more energy on heat that never turns into power. Neus are just the best that money can buy it seems.
