I don't have an official answer for you, but I think it has to do with manufacturing time / costs.

I personally never was looking for a waterproof ESC, but I know that some guys do like that feature.

Now it makes more sense. it was suggested I drop down 2 sizes, I told him I had a 92. Well that is what I have in the Slash. So he suggested I drop down to the smallest spur, that would be a 75. Well once we both were talking about the same sizes, it makes more sense now.

I am running a punch level of 2. It still over powers the rear end and gets it side ways. I might try a 21 pinion? When I have the traction, this thing launches like it is shot from a canon. Maybe I just need to soften the trigger finger some.

So I have the correct gearing. 84/20.


Buzz.

What do you mean a punch level of 2? Punch is measured in percentage from 0 to 100%. You have a VTX10, correct?

I was about to ask the same thing. Punch is a % from 1-100 as he stated. Profile level 2 maybe?

Best thing you can do is go through and list all your settings, no matter how insignificant. That way we may be able to point out any other stuff that doesn't sound right and get you straight.

Dang key board. It is 20. The zero key did not work and I am a very poor proof reader

So yes, profile #2, punch is 20%

I need one of those self correcting key boards. They type what you mean, not what you type.

I even confused myself on this one. Need more sleep.

Personally I never like anything under 75% punch, no matter what class or motor. I always get that feeling like I have negative Exp in the radio... everything is really smooth and then ramps up fast. I know it's just a preference thing, but that's just how I feel.

If you have too much power at 75% punch, then maybe think about motoring down a turn. I did that in 2wd buggy (down to 9.5) last winter and it really helped my consistency

+1 on the 9.5t in 2 wheel! Viper 9.5t is a great cool running motor for that setup.

And very efficient I may add-I average 1600mah used in 8 minute qualifiers.

That's with 30 timing in the can and nothing in the ESC.

What timing on the can? Try 0 timing ESC and start at 15-30 on the can.

Can anyone give me a pinion suggestion for a xb4 4x4?
17.5 motor, 72spur.

Also everyone recons I need to run a fan?

I'm in Australia & it's hard packed clay with 2 big straights (50meters)

yeah, for the tracks out here where they water, they can get a bit liberal on the application and the first vehicles up for that are usually 1/10 scale, so you have the chance of getting stuff wet. the good thing at least is that I run it in 1/10 2wd buggy so its pretty well sealed. I do wish we would run it dry personally, easier to kick off the dust than to de-mud the car.

But 1/8 though, waterproof VTX8 is where its at especially for 1/10 4wd SCT.

Sorry guys been away from the site for a few days....

Orange and Black Edition ESC's are basically the same units - with different color faceplates. 2 - 2 1/2 years ago when the Black Edition came out we did some upgrades (hence the Black edition), but since then, we just put all those upgrades into the Orange. They are the same except the Orange has a longer 2 capacitor pigtail, and the Black has a little smaller, 3 capacitor pigtail. The pigtail design of the capacitor helped improve the efficiency of the circuit - the reason we still use the 2 caps on the Orange edition - we bought a lot to use up.

Their operation is the same. If you didn't know what color you had, you wouldn't tell the difference. The only differences are between the 10 and 10R sizes and motor limits. But a 10R and a 10R BE, are the same. And they are the same cost, unless an end seller is doing something different.

All our units are replaced if something happens. The circuit boards are integrated, so if one part is bad, typically more could be bad, so its a better operation to replace with a new unit than take a chance.

Now, for those who do things like have the Vport wires ripped off or wire harness ripped off -- yes, because of the waterproofing, its not so simple to just "replace" the wires. But if you have had something like that happen its outside warranty protocol already.

On another note, An advantage of the VTX8 and the way we epoxy dip the circuit board to water proof it. - helps to further separate the internal circuit boards - something other units suffer from failure when there is a hard crash boards tend to touch and short out.

so in short, are the black editions not waterproof and the "reds" are?

thinking of picking up another for my daughters vehicle, but I can see benefit to the red if thats the case versus a black to get her driving more.

BTW, the Black Edition is waterproofed, we just didn't worry about advertising it, because we found most didn't care for racing applications. Those who worry more about waterproof, are generally not shopping for this type of speed control. If fact some racers tell us that they won't buy our speedos because they are waterproofed. They say it ads weight (it does), and it makes speedos run hotter (it does not).

Edit - answered your next post and didn't even see it!!

LOL.

The waterproofing to me personally was one of the factors that lead me towards your ESC, mainly due to how they water out here at times but I can see the other side of things too.

need to sit down with it and get used to all the features, so much there that until I delv into it more kind of get lost lol. But I love having the options for sure.
