Thanks again Eric.
That's what is so great about these forums. Where else are you going to get this kind of stuff! A great racer with gobs of experience running through the list of approved USVTA ESC's. That's information to print and save.

Don't be discouraged about not finding a VTA ride as ARTR. It's not difficult or expensive to build your own ground up with all new stuff that you can beat up your self.

I am pretty much ready to buy a VTA ARTR setup and as soon as I'm ready ALL the current adds on here and hobbytalk have dried up. That was something I pretty much expected though. I have 1 possible lead but I won't know anything about that till after the weekend.

Thanks again Eric.
Mike- we have a HPI Pro 4 that is in the middle of a rebuild prior to sale if your interested. It has a JRxr3i 75mhz radio and JR270 servo. Heather just started the tear down for inspection and replacement, it should be ready early next week for electronics.

Anyone else?
It should play the whole hr or so although i have had issues with youtube doing that sometimes
There are quite a few vids of TCM that might work for ya .

Default Temp/Voltage/Mah vs. Timing/Gearing

One of these random thoughts that occasionaly pops into my head.

How many of us use the information provided to us after a run to evaluate our overall performance, car and driver?

Fast lap vs Last Lap over the course of a run in regards to battery performance and gearing/timing?

Motor Temp vs gearing/timing, I know we all look at this, but have you factored in the voltage of the battery after your run and how much we are putting back?

Heat race gearing vs 8 minute main gearing?? How many change gearing for each?

The car whose tires are "squerking" vs the faster car that doesn't make a sound in the corner?

Is your car a touch "pushy" loose in the front side of the run and get better later, or is it on rails up front and tighten up and slow down later?

I know we have all experienced a "soft feel" to the car somewhere in the run, but have you used the above to help diagnose the issue, or just adressed gearing timing?

On our current layout, I will typically use around 950 mah on a 6 minute run and about 1200 on an 8 minute run, with battery voltage at 8.1V after 6 and 8v after 8.

Just a random question to think about

If anything, I would think this would help. Instead of being a struggling company - now they have solid backing with a company that has long supported the R/C hobby. Sounds like good news to me.

This has been in the works for awhile.

Don't think it will be the S2, maybe wrong. The S2 is a budget belt drive, the Apex Series (Associated) and Thunder Tiger are a direct and a shafty (2Se and 4Se).

I hope you're right...
Some S2 specific parts are scarce as hen's teeth and have been for a while...

New owners of HPI could view the S2 as too "problematic" with the belt issues alone that are experienced by street users...

Yep... my thoughts exactly. I work on it on the bench and tweak in practice, but for the most part it's all about the racin'.

Sounds like the stuff we did in the 80's where we geared are cars to last 4 minutes, no hot laps and nobody was woried about motor temps, just runtime.

Any VTA should easily run 20+ minuts on a 5000 lipo.

drop it and drive it like you stole it
