Works for me. That's a beastly truck buzz.

I just came back inside from an approximate 10-12 minute run with the Rustler (I'm trying to limit runtime to about 10-15 minutes so I don't kill my lipos). Everything is the same as previous tests, except this time I loosened the slipper by about 1/6 of a turn, and geared up to a 27 tooth pinion (27/87 so about an 8.764 FDR) .

Conditions:
-Night
-about 84F out with a very warm breeze
-muggy/humid Florida summer night

Temperatures:
Motor- 115F
ESC- 110F
Battery- ~110F with case on, 135F without case on bare cells

So far the Medusa+Mamba setup is great! I wish I could have tested it today when my 1:1 truck's temperature display said 92F though... Took forever to balance charge this pack (I balance charge the pack at .75 amps now since I've been pushing it super hard).

Comments:

I tried everything I could think of to get the motor to heat up. Tons of wheelies, tons of WOT passes and 180 degree turns where I'd brake to spin and then jam the throttle down to get as much current drawing as possible. Motor seems to be quite "happy" at this gearing. The real test will come maybe tomorrow or Wednesday; my vista gadget says it'll be about 87F tomorrow for my area (probably hotter in the middle of the day I'm thinking).
