Have no idea. It's been a while...

I don't know if I've resolved any issues, but I've re-designed my chassis layout.

- flipped diff (positions motor to front and left)
- Moved battery to back right
- Make aluminum battery tray/holder (doubles as rear chassis stiffener)
- Move radio box to back left

The battery tray / chassis brace worked out great. I'm very pleased :). Finally, an effective way to stiffen the rear after losing the upper deck on the hellfire. I'll get some pics up later tonight. Just need to finish up some touches on the tray, and I have to run a few errands first :|.

I had the front and rear diffs opened up. There is indeed a good bit of wear on the crown/pinion. It looks like unusual wear. As if they were run for a time with bad mesh. I will probably need to replace them sooner than later. It seems there is more drag in the front and rears than I would like. These are my first 8th scale diffs though, so I have no basis for comparison.


That's it, wait for pics!

I'm really looking forward to getting mine converted now. Its been sitting in a box for almost a year. Now that I have the Gmaxx and ERevo up and running, I should have some time for it.

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.

I hope you're using velcro under the battery as well so it doesn't slide forward and back. but looks really clean.

Well, when I got it, the diffs were pretty bad. I just got some new "pulled from new Hellfire" diffs from eBay, but never checked them...

I guess none of the pics show the bracing front and back for the battery. There's a standoff bolted to the chassis that rests against the front of the pack, and a chassis brace in the back that rests against the back of the pack. There's no movement or wiggle room at all. I do plan on some sticky backed felt to protect the bottom of the pack from the chassis and mount, but it's not going anywhere ;).


They're not so bad. I noticed though that the crown gear was shimmed in such a way as to push it further away from the pinion, and no shims on the pinion gear itself. Strange, since there was too much play already with the shims removed. I moved the shims to the opposite side, and put one on the pinion gear as well. Both diffs are smoother and more solid now. I think they'll do for quite a while.

I'm so happy with the build all together. This thing handles insane. I can't wait to get another run with the components moved around like they are. I REALLY can't wait to run it with a higher quality motor, lol. In the end, I think I would like to do 5s on a MM and Neu combo.

I have a question - why did you put that AL plate under the center diff? Was that to raise the diff up to the height that LSP motor mount put the motor at?

..love this...I will be putting my E-Helly back together soon too...

video? i would like to see this in action:intello:

he used a LSP motor mount and the accompanying LSP front bulkhead, which had mounting holes that didn't line up with the hellfire chassis, so he bolted the LSP parts to the plate, and the plate to the chassis
