Lower? Higher? Which is it?

The two sentences above contradict each other...he, he...

5.71 is what I run as a final drive on my XXX-S with the quad mag 19t. That should be a good starting point.

Wow! That is a torquer motor. How small/large and open/tight is the track?

Actually these statements are complementary.

A numerically lower ratio would be achieved by running a larger pinion gear.

I've ran that on a large track and a medium size track. Worked great on both.

Rubbish - the gear ratio gets higher as you increase the pinion gear size, lower if you increase the spur.

Eg

Going up 5 teeth from a 22 tooth pinion to a 27 tooth on a TC3 using a stock 72 tooth spur:

= 1:8.18 (with 22 pinion) to 1:6.67 (with 27 pinion)

1:6.67 being a higher ratio than 1:8.18

The statement was contradictary, as is your post also.

Why is it that even with all today's information available with modern instruction manuals, internet websites and forums that gear ratios still cause so much confusion?

Guess we'll never know......

I'm trying to decide which motor to get for our indoor winter championship.

I'm stuck between:

the Peak Racing Dynasty 19 turn spec (with V2 endbell, G13 magnets etc)

and the Orion Element 19 turn Revolution spec (with V2 endbell etc)

The motors seem very similar, but anyone here have anything to say about them? Is there a clear advantage with one over the other?

Any comments would be much appreciated.

Regards

Horatio

Last time I checked, 6.67 is NUMERICALY LOWER than 8.18.

Not sure where you are from, but due to your venacular, I would say outside of the US. Many people in the US deal with gearing at numericaly higher or lower.

Your interpretation is that a ratio of 2:1 versus 4:1, 4:1 is a lower ratio of the first part. This is more applied to fluids and batch mixing. For example, if you mix two liquids in ratios of 2:1 and 4:1, the 4:1 batch would have a lower ratio of the first fluid in relation to the second fluid.

This is the source of confusion you refer to, which is why many people refer to gear ratios numericaly. I would recomend that someone running a 7:1 final drive, to gear down to a 6.50:1 final drive. Refering to the numerical component, and not the relationship between the two numbers.

Numericaly yes, but when you're talking about gear ratios, the lower the number, the higher the gear ratio. That's why on a real car, 5th gear or HIGH gear is closer to 1:1 than first or LOW gear is.

Precisely my point.

And it makes no difference what part of Europe or the USA you're from either 1st gear = low gear 5th gear = high gear - infact it's the same the world over as far as I'm aware.

1:6.67 is lower numerically than 1:8.18.

But in terms of gear ratios, 1:8.18 will always be the lower ratio out of the 2.

any advice please.


final ratio for stock at my local track is 6.86
I run a V2 19 turns for a few weeks now with rubber tires on a carpet track .
I think 6.0 is a verry good ratio for this V2, i try also 5.7 5.8 5.9
but speed was better with 6.0 special comming out from a corner.
with mij normal 19 turn motors i use on the same track 5.6

RE: Horatio -motors are the same ,no difference at all

thanks for advice guys

didnt mean to start a discussion about gearing though lol

i gearded it 1 tooth higher than my stock (24tooth for stock and 25tooth for 19T) ran a treat.

my m8 who runs a hpi pro4 ran his 19T element 3 teeth higher and he was beating all the 12X1 motors, wicked fast

this V2 19T element revolution motor has fantastic torque and goes like th clappers

love it

I've run an old Orion Element stand up brush 19t super stock motor in my RS SD. It was a one off 1000 lap endurance race.

The track was fairly tight, technical and indoors on carpet. The motor seemed to like very similar gearing to the 27t stock motors we normally run. I think this is because we usually run fairly low ratios anyway due to the tightness of the track. 1:7.49 seemed to work pretty well.
