hope nobody gets mad for these ?'s

1. should I delete my original subscription to 1st VTA thread?
2. I have a brand new Factory team TC4 double deck carbon fiber car, which is better for VTA? FT TC4 carbon fiber or TC4 Tub chassis?
3. any tips on either of these cars? Yes I know they are old! but wanted to try VTA to learn how to drive!
So, any mods, gearing, setups, etc... would be GREATLY APPRECIATED!

Since the C rating thing has come up so many times in the past, I bought one of these gizmos from HobbyPartz that measures wattage and current draw. I believe it is fairly accurate and I wanted to measure the actual peak draws of a VTA car. We've figured in the past that the average is about 10 - 12 amps but the peak draw is where the C rating comes in to play. So the results...

About 20 amps!

I started by doing several burnouts to simulate a race start or when you get going after a mishap. The meter actually maxed out at 29.9 amps for that.

Then I did 3 runs with smooth rolling starts to avoid a big draw and ran about 5 to 10 laps per run.

Run 1: 19.5 amps
Run 2: 20.4 amps
Run 3. 19.6 amps

This was on a big track using a Novak GTB speed control, a Ballistic 25.5 motor set to 45 degrees of timing and geared at 3.32 FDR.

This means you need a 6C 5000 mAh battery to cover those peak draws of hard acceleration and a little more than 4C everywhere else. Combine this with Darkside's recent test of his Reedy 25C Wolfpack outperforming a much higher rated pack, and it's a pretty strong argument that C ratings don't matter in VTA. 20 to 25 C packs are more than good enough for this class.
One key thing missing from your assessment is the voltage under load. Based on what you said, yes, a 6C pack would survive being run in a VTA car. However, a pack with a higher C rating (assuming the rating is accurate and not just marketing fluff)will maintain a higher voltage under the peak loads. The motors rpm is based on the voltage input to them. So the pack that can maintain the higher voltage under load will give faster acceleration and higher top speeds. It may be less noticeable if the amp draw is fairly low but there will still be a difference.

A pack with a higher true C rating will always have an advantage over a lesser pack. The gap narrows in the lower current applications like VTA but its still better to have a stronger pack.

It looks like that device you are using can measure peak watts as well as peak amps. Watts are V x A, so at the same amp draw a pack that holds better voltage would output more watts(power). Thus faster acceleration and higher top speeds. It would be interesting to compare and old 20C pack to one of the new 60+C packs. I'm sure you would be able to measure the difference.

i'm fairly certain, at from my sources at the event, he was touching up the orange paint on his RS, so that it passed for a GTB2

yeah, well, that's what happens when you have a life outside of racing - its gets in the freakin' way of racing

I mostly agree with you. I was really just after the peak draw of a VTA car and not trying to spark any new debate over this old topic. I would never advocate anyone using a 6C pack in a race, but I think that 25C packs are more than enough for VTA and any advantage of a higher rated pack would be negligible. Plus we have that whole "warming" theory that the lower rated pack warms up faster and delivers more current at the end of a run as Darkside's track test would suggest. I'll tinker with the device some more and next time I'll look at the wattage figures. I'll get hold of a newer 65C pack that I can compare to some older 25C packs I have. I'm curious to see those results as well.

Any Chinese 25c pack is way more than capable of handling the load from a VTA car. Voltage is about the last consideration. Internal resistance is what will be of greatest importance, considering if you use 1200mAh on a 4000 pack, it's barely more than 1/4 of rated capacity. You're still in a pretty flat part of the curve.

If this really concerns you, the real test would be 2 new packs. Same capacity, one 35c one 60c. As it has been mentioned before, some of the battery gurus/oval racers recommend lower C rated packs since they heat up and produce more voltage.....As usual, i recommend everybody make sure their cars are completely dialed in first so you're not wasting all that massive horsepower...

It doesn't really concern me.. But I am always curious about how theories play out in the real world, so understanding if the higher C rated batteries actually do put out more power (watts) in the same real world car/setup is interesting to me at least. I was only pointing out that just because he calculated that you only NEED a 6C pack to deliver the current required to supply a typical VTA setup and prevent the battery from being damaged, a pack rated that low would certainly perform noticeably poorer than a high C rated pack. I agree, all of this voltage holding/internal resistance discussion is splitting nano seconds. I still need to work on the full seconds with setup and skillz... LOL


But since you brought it up...
Internal resistance is what determines a cells capability of holding voltage under load. The lower the internal resistance, the higher the discharge capabilities, and the better the cell will hold higher voltage under load.

The full cycle discharge curve of a 4000mah pack (or the portion of the full discharge curve that actually gets used) has nothing to do with this. All we are talking about is ability of a lipo cell to hold voltage under a peak load. Yes a cells voltage/performance does drop off at the tail end of full pack discharge, but that is not the discussion since as you stated we barely use a quarter of the full discharge capability.

If you believe that the lower C cells "warm up" faster and then discharge better, why not store your higher C rated packs in a bag with one of those chemical hand warmer pouches and warm them up before using them? Then you wont have to wait for them to warm up. To me this whole train of logic doesn't make sense. If the cells are warming up then its because they are being stressed due to higher internal resistance and the system is asking for more power than the pack can deliver comfortably. When the cell warms up, the internal resistance drops a little and allows it to hold voltage under load a little better. The higher C rated packs can already hold that higher voltage so they aren't as stressed and they dont warm up as much..... because they don't need too! But, I honestly cant imagine really warming up any reasonably decent lipo in use for a VTA car. They just don't require that much power.


But hey.... whatever you believe makes you faster probably does, just from a confidence standpoint. So I say do whatever makes you comfortable.

Here's my two cents:

1. I would keep the subscription to the 1st VTA thread so that you could always go back to it for reference if needed.
2. If you already have the double carbon fiber deck installed on your TC4, keep it. The original TC4 tub chassis leaves you less room to install electronics. Plus the carbon fiber deck is more resilient to chassis tweak that may result from crashes during a VTA race.
3. The TC4 makes a great VTA car. To start off make sure that the number of teeth on your Spur gear is about 1.6 times the number of teeth on your Pinion gear (for example, a 90-tooth Spur and 56-tooth Pinion). That will give you an FDR of 4.0, which is the perfect starting point for any VTA racer.

A cells State of Charge (SOC) will determine its capability to hold voltage under load.

A cells overall State of Health (SOH) will also play a factor typically as well (effects due to number of charge cycles, rate of charge, number of deep discharges, cell temperatures, etc).

Power (Watts) does = V * I, but if the motor draws 20A the 5000mAH 25C and the 65C battery (of same voltage) will produce the same amount of overall power.

For racing (like VTA), the battery capacity is what I'm interested in most. I want to stay in the SOC sweet spot as long as possible. This means my average power throughout the 8 minute race will be greater and maybe help me win that drag race to the finish line (assuming I drove perfectly for 7:59) .

Hey guys, I was looking at the Novak GTB2 w/ x-drive earlier today. Was wondering if anybody uses it in USVTA? I'm using the Edge 2s. Seems to be working great, just curious to see if the GTB2 x-drive is a better performing ESC?

I'd like to hear fellow USVTA racers opinions on this.

Thanks
