Hi, I was hoping someone with experience with this car could help me.

how do you change the rear toe in?

the rear hubs i have seen come in 0 degree, 1 & 0.5

the car says in the back of the manual it has 2 degrees in kit form.


but the rear hub part that is standard on the kit when you look it up in the manual & on losis website says 0 degree?


so if i buy the .5 degree hubs will it make it add .5 degree to the standard 2 degree or take it off?


the manual is a bit confusing in this department.

The hubs will be marked left and right. So if you put the left .05 on the left you will add toe if you put the left .05 on the right side you take away toe.

I would start with the 0 degree hubs then go from there, i always end up going back to 0 degree hubs.

Generally speaking

Forward Drive Ratio = Pinion teeth / Spur Teeth x Internal Ratio (1.83 for XXX-S)

FDR DOWN --> top speed up, acceleration and run time down, motor temp up
FDR UP -->top speed down, acceleration and run time up, motor temp down

But note that these general relationships fall down when you have extremly high or low gear ratios.

The ratio plays a major part (along with good batteries) in getting speed in 540 class. Play around with your gear ratio's until you find a good balance of acceleration and speed for your track without getting the motor too hot (general rule of thumb is I think about 70-80 degrees so that you can put your finger on motor after a race for a few seconds without burning yourself)

Also since we know seem to have a few ppl running in 540.

How much brake do you guys use?

I'm finding I'm having to use brakes now since I upgraded to EP4200s. Problem is I'm finding it very hard to adjust manually the amount of braking using my finger throttle (always seems to go from nothing to too much). I've heard of the stock guys set up their ESC's for drag brake which is basically to have the ESC apply a touch of braking when your off throttle rather than letting motor freewheel. Experimented a little yesterday and car feels very different.

So wanted to check if you guys used brakes, or if you have a bit of drag brake set up?

I dont hardly use brakes at all, i race on a large / open asphelt track with ruber tyres.

I have a one way installed & 1 degree front toe out & losi red springs which are quite soft. so i have tons of turn in.


other wise if you dont want to set up the car different, you can use drag brake on esc if your esc has it. or on transmitter if you want. this is sometimes know as a lazy way to get a poor car handling good, but in some situations is the best option, for example if you change tracks or 540 to stock alot, and only have the one car. & it would be to painful to change setup almost every day.

unless you have the aftermarket spur adaptor, then you can not go smaller on the spur than 86 anyway. and if you go bigger than 40t on the pinion you will have to do some dremeling on the chassis internal motor hole & posibly the external chassis parts where the motor hits as well.

hey are you sure about that, as i thought the lower your ratio the more top speed you have and the higher the ratio the more acceleration

thats why when i ran a drift car i run around 7.5 with a 540 which it was able to keep up with a stock motor and still had resinable temps of 50 degrees cels

also when i run onroad i dont use any brakes, you dont need to unless to avoid a crash but i use a oneway so i dont anyway

correct about the gear ratio the lower the final drive ratio the more top end you have the higher final drive ratio the more tourqe you have im in the 6.5 range with my 19t motor runs really stout

My bad. Wasn't thinking properly when I wrote the post on gear ratios....Edited my original post it should read

FDR DOWN --> top speed up, acceleration and run time down, motor temp up
FDR UP -->top speed down, acceleration and run time up, motor temp down

Sorry for the confusion.

Will now try take off some of that drag brake and learn to coast earlier into a corner once it stops raining...
