undergeared?

[RUSTY XL-5]

Yal were right...over geared lol (I figured so too). I went up to a 86 spur (too lazy to change the pinion lol) and noticed a dramatic decrease in temps.

Before on 17/83 gearing after 30 mins of hard bashing:

motor was 150-160
mm esc was 180 ish


Now on 17/86 gearing afer 30 mins of hard bashing:

motor was upper 120's and lower 130's
mm esc was upper 140's and lower 150's

Much better. Thanks for the help.

Forgot to mention what I found ironic. I havn't changed my gearing really at all over the last 2-3 years. All gearing set ups provided good speed while temps were in check.

on a brushed motor on 6s nimh gearing was 15-16/86
mm 5700 on 2s lipo 17/86
and now medusa motor and 3s lipo 17/86


Interesting lol.
