While it may be true that running a higher FDR will "reduce" the impact of low corner speed (or simply not being able to get on the power early enough in the corner, or whatever) by allowing you to punch out of the corner a bit quicker, i think it also slows down the learning curve to becoming a better driver, because you have less reason to learn to negotiate the corner correctly; whereas if you blow a corner repeatedly and see your car lag there every lap, you're more likely to learn to try a different line and get through that corner better.

With that said, you still have to find a balance in having fun while you're learning; and everyones balance will be a bit different.

At my local track, we have a 3.7:1 limit and almost all of us run between 3.7 and 3.8:1. Our straight is 170ft, followed by a shorter 70ft straight followed by another 60ft straight, and the whole thing can be taken flat out in a 25.5 VTA car and treated like a sweeper. On our track, Passing is determined by who takes the better line through a corner, not who has straight ahead punch out of the corner.

not what my turbodyno tells me. optimal eff is not always max power and in some cases max power is not full timing.

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.
I have my car generally geared around 3.6-3.8, sometimes as low as 3.4. Although I am rarely ever off the throttle. I do see your point though being in the 3.9 - 4.2 range. It all depends on your driving style. I was able to hold off Jimmy once in Indy, just barely.

Ah the off the plane from the UK, into the truck with no sleep, and drive to Indy race . Good times. A good example of two cars setup different, but running nose to tail for 6 minutes ( dam jet lag lol).

Default Novak Mongoose

You guys that are running or have tested the Novak Mongoose. I have a few questions.

How hot does it get especially when you do a lot of braking or reversing?

Does it get hotter with very low (3.8:1) FDR?

I'm thinking of a scenario where I run one in my Tamiya Mini with the silver can 540 and eventually a 25.5 or 21.5 brushless. The gearing is basically fixed at 5.8:1 FDR, so I can't get too crazy there. Novak intends these for 380 sized motors, but the small size and efficiency makes it tempting to look for other uses, just as in VTA.
