I had to add some weight on the battery side on both chassis.

(I like the Ni-MH Batteries!)

Which Nimh did you use ??? The best nimh by far was the green smc 4600mah side by side pack, and you need to individually discharge each cell to 0.9volts before you individually charge them with the Spintec ICC charger: nimh is pain compared to lipo, but it can be just as fast, if not faster(no voltage limits)....Did you also run both cars at the same weight???

For 48 pitch, either 55/35 or 60/38. Robinson for the spurs, pinions will be aluminum above 35T.

Any recommendation for 64 pitch? I have both, but I know the pinion size is limited with the way the motor is mounted.

If you know the tooth count for the 48p gear you want to convert to 64p, just multiply by 64/48. So a 55T 48p spur would be a 73T 64p spur. I know Robinson Racing does 48p gears of that size, I don't know of any 64p spurs in that range.

The lowest I've gone in FDR in my TC3 was 3.2 using 52/41 (48p)

You can go 49t spur with 41t pinion for 2.98fdr in a tc3, but there will not be much gearing flexibility and not much infield punch either.....

Hey bertrandsv87.

The Ni-MH battery I run/use is the Duratrax 3600mah (they run strong with a higher charge rate. . . . . . .so-far).
(I charge my Ni-MH batteries with the Graupner EX1400. . . . . . .my son charged my Li-Po batteries with the HiTec X1 Pro)

I added weight (11 grams - front and rear) to the chassis when the Li-Po batteries were installed until I had the ride height (6mm); compared to when Ni-MH batteries are installed.

I haven't weighed the Tamiya Evolution 5 or HPI Pro 4; with all electronics.

The duratrax 3600mah are perfect for nitro starter box, but can't come close to competing with Smc 4600mah Energ cells with side by side configuration and charged/discharged individually.....Too bad they don't make them anymore....

This thead was started in 2011.

Many cars that were new then are now old.

Would it be worth talking about to wonder if a 1st gen XRAY T3 is still competitive with the lastest gen XRAY T4?

On asphalt the T3 is probably a decent runner, on carpet I think you will find it a bit more difficult than the new chassis.

Here you go, a 2010 Sakura with cheap electronics winning against a fully loaded BD8.

Porsha driving a cheap 8 year old Sakura Zero (2010) wins and beats Yokomo BD8 2018, Xray 2018, Awesomatix 2018 and Team Magic. She is driving the white Protoform LTCR that has been in use since 2011. She ran cheap motor (surpass 17.5 @ $30) cheap esc (Tsky @ $15), and cheap servo (bluebird @ $20).

Thanks for that.

However, I only used Xray as an example.

My point was more about anything that was new in 2011 like a Yokomo BD6 vs the latest version or Associated TC6 vs the latest version of the TC7 etc.....

Nice video, but what would happen if you instead had the best electronics/motor/battery in a cheap chassis ???

The gap will lessen, but will not really equal a modern car that is much lighter (and can put weights where needed for better balance) and stiffer parts. Xray diff is 17grms, no old cheap car can overcome that.
No point running a cheap chassis if the servo alone is more expensive than the chassis. Upgrade! hahaha
