Hellfire conversion

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.

Here's how she sits now. At least you get the idea of the basic layout. Quite a big change from what was there in the earlier pics. I think the balance will be better, and certainly some strengthening of the chassis is added. The battery tray is attached with M5 screws which are tapped into the chassis. You may notice the battery will sit much lower now, and there's some more weight up front. The motor mount is the lightning mount from RCM. The chassis holes did not line up, so I got the matching bulkhead from tower, and mounted the pair to an aluminum plate which I then bolted to the chassis.

I also put some 300k oil in the center. Perhaps that will help with my pizza cutters up front :D. I'm gonna give it another shot with the 8xl and BK and just be easy on it. I'm trying my best to hold out until I can grab up a castle built NEU.
