I did Pre Order one Roller with Alu chassis. I need help with Motor-Lipos-Gearing Please
Car is:


Rlaarlo AK-917 1/10 4wd onroad car.

Rlaarlo says they made it to be able drive 100mph+ hmmm

I did Pre Order the Alu Roller Version. Because i am afraid Carbon fiber dont like bumpy Tarmac so well
I wish topspeed around 65-75mph
I have 4s 120a ESC Brushless , rebranded Hobbywing
I like to use 2s or 3s Lipo pack, 4s will be too Heavy bashing in this little 1/10 car i think ?


Info is awaible at rlaarlo . com

im new member and not allowed to give links and pictures yet.


Anyone know how to Calculate the Final Gear Ratio in this Car ?
I Like to use Speed Calculator to see what speeds i can get with my different 3660-3670 motors i have. They are different KV. I just need know the Gear Ratio. Everything else i have info about already.
Please help.

I have many motors and couple ESC brushless i dont use . ESC Are 60a and one is 120a 3-4s both Unsensored brushless
Motors i have many different 36 size brushless

Rlaarlo will start send these cars 20/4 . They are at Pre Order now.
