no it is not what their recommend. i have today 15/72. but i need moore speed.

i think emaxx original is 68t. and they recommend 12t. so i think i will try 12/70. anybody that have used that gearing??

[Arct1k]

12/70 is slower than 15/72 - The reason they choose the gearing is to avoid overheating - just gradually up the pinion and check for temp issues.

[Maxxrickard]

is that true?bigger pinion is the trick!
thats bad i hav allready order 12/70...

[Arct1k]

Well you said you wanted to go faster...

15/72 = 4.8 revs of motor for 1 rev of input shaft
12/70 = 5.8 revs of motor for 1 rev of input shaft

i,e, 4.8/5.8 i,e, 18% SLOWER!!!

Just think you can now run 15/70 = 4.666 revs of motor for 1 rev of input shaft

Should be about 3% faster if you can notice...

in Novaks test is 12/68 faster than 14/68 is.
can i get moor speed in an other gearing than 15/70?
the temp is not a problem because i the esc have samr sort of temp protection

[Arct1k]

They can still cook even with thermal protection - faster with lower gearing would imply over geared already i.e. motor can't spin faster.

A bit like driving in 5th gear up a hill if you drop down to 4th you can actually go quicker...

Basically you have too more options to try... 12/70 lower gearing to see if that was holding the car back or gear up and see if motor will take it with 15/70

i did send an email and change my spurgear to 66t
i will try 15/66
15/66=4.4

[Maxxrickard]

i need my car to get quick not high topp speed!!!

[Arct1k]

Gear DOWN for faster acceleration - gear UP for faster top speed...

when you said more speed I took as top end vs acceleration... 12/66 should still be ok...

[Maxxrickard]

okey but if i just need acceleration?
12/66 gets the best acceleration and gets okey topp speed?
i like when the car makes wheelis..

[Arct1k]

Try the 12/66 or buy a mmm and do backflips...

i will not buy a new motor yet.
it was not possible to change my order so i will try 12/72 or 12/70. wich gearing give me the best acceleration?

you told me "Gear DOWN for faster acceleration - gear UP for faster top speed..."
it that the spur och pinion?
will a smaller pinion help me get better acceleration?

[Arct1k]

Gear down means smaller pinion or bigger spur

Gear up mean bigger pinion or smaller spur
