Hiya,

Where do you race? Which track I mean?

Hiya,

Down at crystal palace ( London ).....what about yourself ?

Seisick

Ecuador, Southamerica, running on a new race track. rear tires end up 6mm smaller than front when using stock belts and one way. if using the same compound. such as 42. any suggestions on truing at least the front ones, i was thinking about 3-4mm split. so the handling will not differ too much as the tires wear out.
if using the front diff with stock pulleys, the wear is the same?

Here in the USA a lot of guys run 40 fronts with 42 rears. If the rears are wearing 6mm , are you talking about starting them as new? Have you tried to true them down first?
When I was a the Nats. in Ohio, I started the tires at 58mm and could run practice, 4 qual. and the warm ups for the qual`s.

For 1 hour mains, the racers started the tires out at 60mm, and still had tire when the race was over.

I've never heard of anyone running softer fronts than rears......

generally F & R are run the same with the front's possibly slightly harder- ie. 40 rear/42 or 45 fronts.

seriously there r guys who does, which bring us to driving style & setup preference . i myself did try but was more comfortable with the same shore all round

hi guys. i am new to mtx3 and 1/10 scale.

what is the correct way to setup brakes with the oe-way up front.

cheers??

I will often run softer fronts than rears, it helps even out the tyre wear and is by far the easiest way to get steering. On my home track I run one front 35 and the rest 37, most don't know how I manage to go inside them on the fastest sweeper.
I bet most have radios with steering balance and dual rate but never use the features they paid the extra dollars for.

I don´t have access to a tire truer right now, I´m saving money with some friends of my track so we´ll purchase it later. tires 42 front and rear end up with a 6mm difference without being trued if using stock belts and one way.
I´ve never tried running front softer than rears, but according to slotmachine,I will never get a fast set up that has perfectly even tire wear.It just doesnt work like that, but anyway I´ll give it a try compare times, handling wear, etc; and the other temporary solution is to use only the fronts, and wear them down.
now here´s the thing that I´d like suggestions, if using untrued 42 ellegis all around, stock pulleys and one way, the rear ones end up 6mm smaller than fronts. To what diameter do I have to wear down the front ones (remember I dont have truer now) so handling is consistent and wear is similar? I was thinking on running the front ones at 62 and rears not trued at 65mm. suggestions!

rjl

Seisick, perhaps you should get 3 pair of rears to one set of fronts and change rears with every tank or heat, get a good vernier and always keep the front smaller than the rears with a one way, and very close to the same size with a diff.
To do truely fast lap times you will need access to a truer even if just to radius the edges.

hi there.....frankly at least to me, one way means no brakes

seriously u just need to set your braking so that it would not tail out....that is how i did to mine....u wouldn't get the kind of braking that is available with the gear diff/solid....good luck

KyoshoKev

ok.. i was seting up brake last nite...

i do like this....

set brake epa to max.

drive in a straight line and then apply full brake.... if it spin out then decrease epa..

repeat untill when i brake in a straight line, the rear does not kick out

would this be a good approach.

this would give me max braking but not enough to make the car spin out?


also, other than the fuel tank hole in the body, should i make more body holes? or the less holes the better for better aerodynamics etc.

cheers

i think u got the braking thing... anyway as to holes u really need them to help cool your engine...and normally (for club racing) is 1 front usually 50mm, 1 rear 70mm and both front side windows..

I'm even further down ... in Aldershot.

Do you have track pictures of Crystal Palace? I plan to do the nationals this year and can't find much info about your club. In fact, do you have a website?

Thanks and looking forward to meeting you one of these days a t Crystal Palace!

Sow&Steady

I do that a lot if I feel that the car is not balanced enough. Another reason is that I run the one-wa a lot and with it, your rear tyres wear a lot quicker than when you use diffs or a solid front axle.

Lastly, it is always easier to dial out steering rather than not have enough.
