There are 2 screws holding each of the battery covers, one on each end. It takes a minute to remove them, but not too bad.

I just received an aluminum tranny case with hardened steel gears from Hot Racing. I have not installed it yet as I want to see how the stock one will last.

Sounds good! And maybe someday somebody will make an upgraded diff.

I didn't know the revo platform had a "downkick" to the rear suspension...

Yeah, I didn't either until I was getting ready to assemble. It is very subtle, but it is there. I have since read that the 1/10 version does as well.

I wonder what the purpose is.?? It kicks down toward the ground right? Pretty sure the Maxx doesn't have this feature.

kazuaki · 10.01.2009, 10:38 AM

Yeah, just a little. I'd say half as much as the front, or even less.

nitrostarter · 10.01.2009, 10:53 AM

That downkick has something to do with the suspsension geometry and optimizing the force that applies the tires to the ground. I can't remember the word exactly...

It gives you what is called "anti-squad" angle, I think.
On 1/8 RCs it's adjustable.

Sweet. For 1/8th scale is it dictated by the rear brace thingy? The brace that connects the top half of the bulkhead to the chassis?

nitrostarter · 10.01.2009, 11:04 AM

Its dictated by the plate bolted to the front of the REAR diff. The Plate bolted in the rear is for Toe adjustments.

Well damn that's a nice build!

Honestly the 16th's were really kind of boring me reading about until now. This has truly gone from just slap a big motor in there to something of much more inspiration.

I really like the look with the body and wing but agree with PBO on the changes. I think in your case he was saying that stabilization is more important at this point than downforce. As well too much down force on the rear can cause the front to lift as well.

On another note if I was you I would get some more of those chassis made and sell them. I am sure you could turn them over pretty quickly.

As far as the diffs go that will be interesting to watch. Maybe linc will find a way to fit LST2 diffs in the mini revo as well.

That would be something to see. The LST2 diffs are the size of the Mini Revo front end... lol

I do agree that they are rather boring. I have one. Its fun to go 50mph down the street. But it does flip rather easy and anything taller than dirt isn't fun to drive in...

kazuaki · 10.01.2009, 12:08 PM

My goal for this one is to approach triple-digit speeds. There will be nothing boring about that. I gave it a quick test run with the old EZRUN esc and some small 2S packs I had in series (4S). I made multiple passes at just over 70 mph and the chassis seems very stable so far. It is much more controllable than before. I can even make steering corrections at 70 mph without getting the truck all upset. Also, no issues with unintended wheelies so far. I need the new ESC so I can run this with the big packs on 6S.

nitrostarter · 10.01.2009, 12:09 PM

Can you fit a MMM in there? or a RX8?

And how's the pinion on pinion holding up?

kazuaki · 10.01.2009, 12:14 PM

I believe I can fit an MMM. I'd know for sure if the one I sent to Castle for repair would ever come back

I made the mistake of running aluminum on aluminum on the pinions. That did not last long, even on 4S. I have some RCM Mod1 pinions coming in the mail today. I got a 25t, 23t, and 21t. We'll have to see how well they mesh with each other.

Does anybody forsee and issue with using these?

PBO · 10.01.2009, 06:25 PM

I'm basing the aero theories on my own experience with my Rustler

Sorry, I'm being lazy by just posting pics but I think you get the idea. The rear wing is a BRP Super Wing & the forward splitter is a 1/10 TC rear wing...my initial issue was to stop wheelies, then blow overs, then straight line stability. My set up generates a lot of frontal downforce, which solves the first 2 issues & my rear wing is more for extending the cord length of the vehicle which smooths the airflow exit around the transmission & motor & it also provides a mounting position for the vertical stabilizers. These are important to help the vehicle track straight at all times

All that being said, aerodynamics is extremely complex & everyone has their own theories. I'm about to work on my truggy which has similar issues to the 1/16 revo. I'm hoping a small forward splitter with a low downforce rear wing incorporating vertical stabilizers will be a good starting point
