I'll give the 69/30 a try thanks for the help
If you are already having motor temperature issues with 76/30, then 69/30 combo will make it worse.
Formula for calculating Final Drive Ratio for the RB6,
(Spur Gear / Pinion Gear) x Internal Ratio = Final Drive Ratio
Example:
(76/30) x 2.6 = 6.586
For a blinky 17.5, that ratio above is already considered pretty safe and suits very technical twisty tracks. FYI, i don't run LRP X20 motors so i'm not too sure about their typical temperature range.
When you say "too hot", what is the exact temperature with a temperature gun?
