My e-revo brushless edition build

[mistercrash]

Whatever you say kid.

I ran the second pair of Turnigys 2S1P 5000 mah tonight and got 15 full minutes of hard running. More like a race simulation than bashing. Not bad and the power was very very good. I'll let them cool down and recharge them later tonight. Right now, I'm very happy with these batteries that I bought for $19.99 each.

That CF holder I made for the MMM did very well. The MMM didn't move. And by the way, that MMM I accidently ran on 10S a couple weeks back is still running like a champ. Go figure.

Cool MC, I'm adding these pics to the collection that I allready have of mine and yours....I also had a PM today about the CD as well.... for parts info...ect., it seems there is becoming a interest in this diff design, I have sent the info to Mike twice and have yet to hear anything from him...maybe at the bash, I could talk to him....

It would be cool to have someone market an 8th CD for the ERevo. But keeping the selling price under let's say $60 is quite the challenge IMHO.

One thing that I haven't discussed in this thread is weight. The total weight of the truck. Many of the parts used on the ERBE are from the nitro 3.3 version. So originally, those parts were designed for a truck that weighs 10 pounds or less. A RTR ERBE with beadlocks and a couple 4S lipos in parallel can weigh much more than 10 pounds which I think can put a lot of strain on many components that came from the 3.3. So how much does your ERBE or conversion weigh? It would be cool to see if there is a big difference between conversions and ERBEs, or if there are big differences between ERBEs and ERBEs or conversions and conversions. To seriously compare the weight of different trucks, I say to weight them without tires/wheels and without batteries because there are huge differences in weights of tires, wheels and batteries. So take off the batteries, the wheels, put back the nuts, body and body clips on and weigh the truck.

Here's the weight of my ERBE:

3352 grams or 7.39 pounds.

I got a couple LST2 diffs on ebay for cheap because I thought it would be nice to build a couple spares for my ERevo. So in the process of shaving a little off the thickness of the diff cases to have them fit in the ERevo's bulkheads, I ruined one set of cases by taking off too much. So now I have one complete spare diff built and one diff without a case. No big deal.
Looking At that case less diff I thought, I bet I could make a center diff out of it. So I did, but instead of going with threaded holes in the ring gear, I made three holes, counter sunk from the inside of the gear to secure threaded stand offs with flat head screws, the output gear will be screwed on the other end of the stand offs on the outside of the ring gear. I saw this idea somewhere but I can't find where exactly. I wish I could because I would mention the name of the person who came up with the idea of the stand offs. It was much easier to just make holes in the ring gear and not have to put M3 threads in them. Another thing I like about it is that it is actually smaller from end to end than the stock Traxxas center diff so it will be easy to position it perfectly with shims inside the tranny. And it is thin enough to use the output gear to it's full thickness, no need to sand it down on the belt sander to make it fit.

did you use revo output shafts? is the gear you are using from a e-revo center diff or the gear that the e-revo comes stock with?

[mistercrash]

I used the TRA5415 and TRA5416 shafts from the nitro Revo center diff. I cut them to the right length and put a hole for the pin. The gear is TRA3984X so yes it is the output gear that came with my ERevo Brushless Edition.

Sweet. I think Mike sell something very similar as an upgrade to the stock unit, a sister product to the slipperential

Really, I didn't know that, never saw it in the RCM products. If you have a link that would be swell.

One of my bearings felt very notchy in a rear axle carrier so I decided to change it and check the other ones too. My carriers were starting to show signs of wear so I decided to change them. Instead of going to the same Traxxas carriers, which I like very much, I reinstalled my RD Racing carriers I had lying around and I will run those for a while. I forgot how great they are, the suspension moves very freely but it feels really tight, by that I mean there is no slop at all. Just for the heck of it, I took the metal rings off the Traxxas carriers and press fitted them on to the RD Racing ones. They don't really need it but I wanted to see if the rings would fit and they do.

This is news to me as well

[suicideneil]

Best.
Typo.
Ever.

That ment to say "should sell"...

[mistercrash]

Yes I forget to type words also, it happens me all time. It would be very cool to have a RC Monster 8th scale CD for the ERevo. We already have the hybrid diffs (been eyeing those recently) so an 8th scale center diff would be awsome for a complete 8th scale drive train. It could even be ordered with the gear you need for either the ERevo or 3.3 nitro Revo.

I had this Duratrax Pit Tech car stand I wasn't using so I modified it to use with my truck. It just needed a stronger base and to be a bit taller. It is sturdy and swivles on a bearing.

I got this VW Baja body. I have a simple theme for it that should be cool. Now that it is trimmed, I am wondering if I should use the wing or not. With no wing, I think it looks good, the body is very strong and the top is high above the motor so I bet it will protect the inside of the truck. Also without a wing, the truck would be a little lighter. But since this truck is mainly used for racing, I wonder if it will affect it's jumping characteristics if there is no wing. With the wing, I would have to loose the body's engine compartment completely.

I don't know

[mopar1994]

i think you should not use the wing with the bug body. do you have any video of ur truck in action?

use the wing it will look like its very competitive but your still there to have fun lol
