This is in response to VTA racing at R/Car (Indianapolis) on Sunday.
I was TQ in VTA and my car was turning the fastest laps through round 2. In round 3 there were other local VTA drivers that had better top 5 & top 10 lap-times, but I drove more consistently to secure TQ. I didn't notice any VTA car that seemed to be faster than any other in a straight line during qualifying. I led most of the main (finished 2nd), and also didn't notice any cars that seemed faster down the straight than my car. That is not to say that other racers didn't notice/experience a situation where another VTA car seemed to be going faster.
Without knowing all the variables involved, it is hard to say why one car was faster (actual or perceived). Assuming that the driver(s)/car(s) in question were running a VTA legal speed control & motor, there really shouldn't be a huge difference in straight speeds. Since the switch to the 2010-2011 VTA rules, I've seen the closest racing in VTA ever. I've raced with some of the best VTA driver's in the Midwest over the past several years, and setup (not speed) normally wins the race.

Here is what I'm currently running in VTA:
- FT TC4 (basic setup is front diff, silver springs front/rear with 50wt front/35 rear and rear sway bar)
- Novak GTB without lipo cut-off (I use drag brake)
- Novak 25.5 Ballistic (converted from a 17.5 Ballistic that was used in RCGT. Purchased 25.5 stator directly from Novak, but reused the rotor)
- 3.87 FDR (82/53 x 2.5)
- Thunderpower 5000 50c (that is 1+ years old)
- HPI Cuda (replaced a Pegaus Mustang. Sits a bit higher so I may need to slightly adjust roll-centers)
On Sunday, I was using tires that are 3 months old. The fronts are starting to lose their tread pattern and the rears are starting to swell. Traction was high for normal club racing, so I adjusted by using less traction compound.
Other than fine tuning setup, I've run the same basic setup when I race on carpet. Some days I'm better than others, but the car is normally competitive.

I'm looking for a set of the HPI '66 Mustang decals with the white hood and roof stripes. Does anyone know where I can find them. HPI does not sell them separately it seems.

I want a re-match...Im not use to being a lap down...I like Thunder Jam when this pic was taken...lol...the black and white is yours...

Example, my GTB/17.5 X12 with optimal gearing for my track was slow in straight line speed compared to the rest of my field, and ran at the 180F mark. Simple switch to an RS(no boost!) with no gearing change brought that temp down to the 130s...allowing me to gear up radically and get my car's speed competative with everyone else while still maintaining safe temps.
This mirrors every other persons experience that I've ever talked to or even heard of with the Tekin/X12 combo.
That temp model, though, does not hold true for every motor out there when paired with a Tekin.

we know...but Im more of what the USVTA esc list is more fair so it doesnt even come into question....just keep from second guessing and keeps tech real easy...where you guys racing this weekend?

well maby maby not.jgram was running a 4.9 frd on #2 line
i was running 5.2fdr and timing 3/16" past the sticker and would eat him up anywhere on the track for the first 4min after that mine got spungy and i had to role thru the corners better to stay in the powerband of the motor but even 7min into the main i had more strait speed but it equaled out in the infield

So you geared down for more off the line and balanced it with timing for top end. ???
