Best motor fit for 6s

[TexasSP]

I think the medusa's have different characteristics than the neus and will need higher RPM's to run efficiently. I ran the 1500 in my maxx and couldn't keep the heat down. I had to gear for around 35 to keep temps on the motor under 180. Asheck on the other hand has had great results with the 2000 so who knows. I do think the ambient temps are a major factor as it is always in the high 90's in Houston from April until October.

I run a 1500 medusa 60mm in my hyper8 on 6s. It does get a bit warm. Currently geared 14/46 with the 43/13 diffs and crimefighters. Plenty of power, and very smooth, but the heat does worry me a bit. I may try gearing up a bit, and changing the timing on the quark. I also have a 1600kv 60mm medusa to try. Not sure if the added rpm will help...
