Thanks for that.


Do you know what the ratios are for the 2 speed tranny?

Thanks for that.

The high ratio is 2.27.

I can't recall off the top of my head but i'll get another chart together and post here.

 

[M1tch]

Thanks. It would be useful just to work out wheel speed difference.

I'm not understanding the "rollout" chart... 86t spur divided by a 14t pinion gives a 6.14 ratio. How do you get the 7.86 ratio?

I think Rich is using rollout to define how many mm the truck rolls forward for 1 rev of the motor.

7.86 mm per rev on a 115 mm tire.

A little concerned about that ring/pinion ratio...

On the roll out ratio question you gotta remember it includes the axle ratio not just the pinion and spur..thats the difference your not seeing...

 

[Jaketheone46]

I do wish they would have gave us a better axle ratio even if they had to make the center of the housing just a tad larger...even if a tad larger they would still be the best looking plastic rtr housings on the market...right up there with the t rex 60's I think.. and definitely better than the ar60 due to the ar60 width...if the ar60's was in scx width they would kick ass too...I so hope aftermarket makes a super hard spiral ring and pinion with a super small pinion and as large as possible ring... maybe get closer to a 3 to 1 ratio if possible.but I do love these housings..

Gear chart updated to show the Twin Hammers ratios.

I am still a bit confused. If i go for the 2-speed option the first gear is just like the original ratio and the second adds an go-faster-ratio?
I am currently thinking about which motor to buy and if my thoughts above are right i'll go for a slow high-torque one for powerfull crawling and shift into second for fast passages and drifting in the snow.

Hey rich, what's the buggest linion you can fit in the Ascender with the stock spur?
