what gear ratio do you usually use. for me i use 7.23:1 gear ratio since it has longer running time and more acceleration. but i love drifting and there is a web site that stated 4.97:1 gear ratio perfect for drift.

how about you all, which gear ratio do you use.

I'm currently using 5.971:1 gear ratio for drifting. 17 tooth pinion and 29 tooth spur gear.

haven't touched the gears... so mine is stock... don't know what the gear ratio for stock is...

Stock gear ratio is 7.233; 15t pinion, 31t spur.

So if I was going to use PN Speedy AD motor which is a 39 Turn,
is 19/27T gear too low? The reason I asked is I was using Atomic Standard motor to play with and just for the heck of it, I changed it to a spare
Speedy AD. It did ran faster top end so did not think much of it for days.
Suddenily out of no where, it started to run slower and battery life shorten.
Worst case senario happened was that the motor got so hot, it actually melted the chassis! Now I replaced entire chassis and stick back in the Atomic Standard. Did I screwed up big time in gear ratio?:(

Some older model motors run hotter than others; try their new ones. Atomic Stock R motor is a good choice for AWD. You will notice the cooling effect since it was specifically designed for this chassis. You may also consider Chili or Atomic Stock motors. Gearing aside make sure your drivetrain is free from any resistance. Check motor temp. frequently to prevent costly mistake. I have run all of the above motors with 19/27 gearing and never had a problem with heat buildup. The Chili motor may draw more amps so be careful when running long mains. Home made cooling duct also works. You may also remove plastic material above the motor for better cooling. A lot of the stock chassis material can be removed without compromising durability.

I drive 16/29 in my standard ASF Awd
