Default Kyosho V-ONE RRR gear ratio

Hey, Can anyone tell me what would be the best gear ratio to use on a high speed, 200ft straight track on a "Kyosho V-ONE RRR"?

Unfortunately I don't know the transmission ratio off the top of my head or your engine but if you run 60/58mm tires then you want to use the 17 and 23 pinions and the 60 and 55 spur gears. Possibly the 56 2nd gear if your engine can't lug the big gears. Try moving the 2nd gear shift point around as well to take advantage infield if your motor can pull it but if it is shifting just before your braking zone shift later for the straight.

If you are running full size 64mm sized tires, then you could get away with 16/22 and 60/55 still.

Picco based engines can pull tall gears so you can basically run 17/23 and 55/60 on every track. you could get away with using the 61/56's and just put the larger pinions on since your track is only 200'

I would invest in some calipers to read the tire size (digital can be had for $30 or so) or at least a metal ruler that reads mm (6" is fine) that can double as a ride height gauge.

It is most common to run a 2mm split because of tire wear and front/rear ratios, 60mm in the rear and 58mm in the front lets say as well as running a softer tire in front (40 shore) and a harder tire in rear (42) shore is a good starting point as well.

Why softer in the front I always thought it was the other way around. Is that just your personal preference or have I just been adapting my driving style to an incorrect settings all these years Can you elaborate please?

It is a preference thing for me on most tracks. 2mm split (60mm rears, 58mm fronts) usually wear evenly with say 40sh in the front and 42sh in the rear. Some tracks require a larger difference like 37sh front and 42sh rear. Not really for traction, but to keep the tire wear the same during longer races.

I mostly drive with off power steering (and a spool) so I expect my car to dive in when I let off to scrub speed instead of braking and then I roll on the power on exit (left over style from electric touring)

Same here.....so why softer in the front and not the rear to keep the tail from coming around so easily?

Oh...I went back and read the whole thing....

So more for tire wear and not so much for traction.....hmmm never looked at like that.
