lol, yeah, about 5 minutes worth of fun!

I had the same powertrain on my Revo conversion, and was able to run through most of the pack before needing to stop for a cooldown. I'm not quite sure why it's running so much hotter in the hellfire. Perhaps the CD is unloading too much ?

I'm sort of holding off on a new motor purchase until the Monster Max combo shows to be stable enough for me to spend money on. I'm thinking the castle neu should be pretty good for my application on 4s. I would love to spend the money on a 1515 right now, but I just can't.

This is not my first RC, or my first conversion. I have 2 revo's that I've converted, a heavily modded e-savage, and a heavily modded emaxx. that's just a few of them. I have quite a collection of tamiya's as well.

I'm just still a bit baffled by the hellfire heating things up so quickly. I was scared of burning up the 9920, so I switched it out for the 125b that was running on the emaxx. I expected the 125b to run a bit cooler than the 9920 on the same setup, but it seems that is not the case. Does anyone feel the 13/52 gearing is incorrect for this setup ? I know I need to tape the tires and such, maybe that will help. Also I'm sure heavier diff fluid in the center couldn't hurt.
