I love my viper vtx8 and I am now in the process of building a sworkz s104 ek1 any recomondations on what to install thinking one of the copperhead combos.

Or a link to setups?

What is your current setup you are using right now?

That may be helpful to see if you need to turn up something, etc.


As for my question about the loss of power, I woudl like to know what causes this?

To me it seems almost like a "Rev Limiter".

As for the throttle punch raising suggestion, my only concern however is that on the loose conditions I run on, having the punch set (I have to see what its at) is useful for wheel spin issues, etc. If I have to raise it that high to elimiinate the issue, I run into other ones on the track itself. I am hopeful that maybe something else can be done due to the conditions I run on. I appreciate the advise though!

Nick@Jet - its a tough comparison between the two. 1st set up runs sensorless, which will fell more abrupt (on/off switch) also at 4700kv to 4300 kv, is about 10% more power available. Same gearing similar set up -- yep, its doing to feel quite different. Being sensored only the VTX8 is going to have a smoother overall operation. its also going to have some more setting to try and fine tune. Doesn't mean its going to make a v6 run like a v8, but you can tune what you have. As for settings. Profile 5, is a good base point to start with. Might want to lower throttle freq slightly (to get little more throttle response for the jumping). There are a bunch of factors that go into that as well (chassis, diffs, body, motor). The lower kv motor will provide less power to "maneuver in the air. And as Cain said, see the whole of the set up helps other than making guesses. You can PM it to me if you want.

Neverstop - the sworks you listed is a 1/10 scale. I would recommend the VTX10R Black Edition and probably a 6.5 or 7.5 motor depending on what you feel you can handle driving wise.

figured I'd ask this to get a current opinion, when using Viper gear in a Truggy do you void the motor warranty with this usage (assuming regular usage, not nuts stuff).

Saw a recent post by Tekin about buggy motors in truggies that gave me a bit of pause, so curious about your motors as well.

If you gear it correctly, monitor the temps and use it correctly == there shouldn't be any issues.

Other than saying its a different KV, don't really see what would make a difference between a buggy and a truggy motor. If they are both operating correctly, they would used correctly by the racer, they should work. Are there little things that could be done to "fine tune" it for a certain style of vehicle. Yes, majority of people wouldn't feel the difference. Most that say they do - its psychological.

Okay thanks. I know Tekin mentioned that they see the truggy motor should be used with truggies, but in general the power delivery and performance on the buggy stuff feels fine in the truggy, especially as the truggies aren't that much more in weight (the ET48 at least as reported) than a buggy.

Do you have any more info on the issue I mentioned about loosing throttle input mid air? let me know if you need anything to diagnose this. As it sits right now, it really only happens in 4x4 SCT on 2S. Never had that happen on my 1/8 buggy.

Hello guys.
I have in my 22-4 the VTX10 8.5 combo.
I just up graded to the new A64 softwear.
I used my EZ Link to verify that it is up dated to A64.
My new problem is that now my Viper ESC fan doesn't come on any more.
Is this normal with the new A64 softwear or is there a setting for it now in the EZ Link somewhere?

Thanks
Tom

Tom,

Yes, if you have an older unit and updated to A64, it cuts off the power to the fan mount on the bottom of the speed control. Updated models have a mount that is between the capacitor mounts on top of the board. This way the fan runs straight off the battery.

Its a more efficient way for the speed control to work, previously it ran the fan through the BEC, which really wasn't an issue but it did limit voltage as BEC voltage is lower. you can actually take the wires from the fan and solder them right to the positive and negative battery posts on the speed control and get the same effect.

Cain, last time I heard of an issue with anything like that was over 2 years ago with the original a59 software - that was the issue we had with Tekin motors the sensors didn't seem to be able to keep up with inputs, so we had to re-write the software (they were the established motor, we were the "new guy" speed control). Make sure you esc has latest software, check sensor in motor? PM me what your throttle settings are.

Thanks, I'll get some info and post.

why no setups for the vtx8 on the website?

Because no one sends us one!!!

In all seriousness - majority of the setups that we have gotten were stock profile with little change in brake and/or change in throttle punch.

The baseline settings have been really good for the VTX8.

alright I sat down and looked at my throttle settings here they are:

Frequency: 12000Hz
Punch Control: 60%
Curve Linear
Deadband middle

I have been thinking about getting some new esc's and been considering viper. It would be for 1/10 scale and needs to run lower turn motors like 5.5, 6.5, 7.5. I've been looking at the vtx10r and the r black edition. What are the differences and how good are these esc's? Thanks in advance.
