The race for second is pretty impressive given that it was so close after 576 laps.

To add to what Monkey said, Thank you guys for coming down. You made the race day. I guess you know that. I hope that we can get a bigger turn out in the future and offer you guys more competition.

With a 25.5 I'd aim between a 3.75-3.80 FDR and temp it to make sure that gear ratio isn't getting anything too warm. Nice car by the way. A number of guys and one gal run that chassis in VTA locally and they all handle really well.

I'm having a hard time adjusting to these super low FDRs. The first day racing at Leisure Hours this season (big track, long straight), I ran a 4.12:1 FDR. I think some of the less experienced VTA racers thought I was cheating because I was passing guys exiting the turns like they were standing still. Some of them were running as low as 3.6:1 FDR. By the time they got up to speed on the straight away, I was so far ahead that they couldn't make up the ground. The shorter gear ratio is far more forgiving after a wreck as well. The tall gearing is "no mistakes allowed."
Two weeks later, a couple more fast guys showed up. I geared 3.96:1 to keep up. I had the fastest lap but couldn't do it consistently and wound up with a second place finish. But the car felt absolutely flat out of the turns and trying to get going on that uphill straight away. I guess its just a matter of personal preference, but I don't like my car when it is geared anything below 4:1 FDR.

I didnt ask the question but I like the sound of that. Our straight is 103ft. Doest that make a differrence?

The track I was racing on has a 220 ft. straight away that had the last 50 ft or so cut down and turning into a gradual sweeper. It is exactly the type of track where a very low (3.6:1 or so) gear ratio should work to your advantage. But I've been able to stay in front of most of the field running between 3:96 - 4:12. On shorter parking lot tracks with straights around 100 ft., I do very well between 4:12 - 4:20 which is expected on a shorter track with more turns. That's why I just don't get it when guys come on here talking about their 3.8 gear ratios. If you think about it, most passing is done while exiting a corner. Very little ever happens in the straight away. Full scale road coarse racers tend to care less about top end than they do mid range power. It's the same situation. Gearing a car at 3.6:1 is like driving around in 5th gear all the time. Any sport bike riders out there? When is the last time you took a corner in 5th or 6th gear? You hear your engine knock and struggle for more power, so you down shift. With our single speed transmissions, we have to make a choice. Brushless motors provide a ton of torque throughout the RPM range, but the effects of gearing too tall are still there.

If you have a car that maintains excellent corner speed then the 3.8-4.0 FDR range along with the right amount of motor timing works very well. At least over the winter on the shorter carpet tracks, I had great success with this range of operation.
