[Alternative model] 42109 B model-Futuristic speed demon

[msk6003]

42109 Top gear rally car is TO MUCH expensive. Same price with 42039 24hr race car, 42052 heavy lift heli, 21309 saturn, 70425 newbury high school.

And evan low part count all of set above! Slow as basic! No B model!

So I trying solve of 2 problem. Slow speed and no B model. And this is resault.

The Futuristic speed demon.

Ok. This is my best design. All you know, this set has low part count.

And I sacrifice differencial and gear powerd steering for get lot of gear. Steering now working with some crank-like mechanism.

Gear ratio is 3:1 acceleration from motor and I don't use lot of part so this car is much lighter and faster than original rally car.

Unfortunately, I don't have another phone or camera to take video. So don't have video yet.

Instruction in rebrickable soon....

I think you can still keep the differential and remove just one 12z half gear to mesh with it. The differential should still work fine with 4 12z half gears.

But this set don't have axle joiner. just ONLY one #2 connector. I first tried 36t->12t bevel like you saying but it is neally impossable without axle joiner.

And even if it is successful, considering the 36t->12t 12t->28t gear combination, it will eventually be the same as the existing model.

And I tried it before. new diff is still working even 3 gear inside.

Interesting design, reminds me of some old car from the 40ies maybe? A singular wheel at the rear would also be cool, but maybe not that easy from the existing parts and the propulsion motor would have to be placed higher. So good as it is.

It definitely looks quick in your room and can also drift. If the original 42109 could be as quick as that, that would be something.
