Default Trasmitter Set up for new Driver

I have run my Losi XXX-S Electric touring car on a tight carpet track about 5 times now. (stockmotor, foam tires)

I have improved a bit each time, but my big difficulty remains adjusting the speed down while cornering.

I have an older Futaba controller with a lot of trim adjustments and I am willing to spend $100 dollars on a new controller if it wouold help.

My question is what kind of adjustments or settings can be made to a transmitter which will make it easier for a new driver to learn to control car.

For me, steering balance, dual rate and exponential.

Haven't experimented with steering punch or 2-way steering speed on carpet yet but all the other functions I do use frequently.

I'm using balance, EPA and off-set for the throttle. Nothing else.

Dont expect that a new TX will take you to the podium. Best case, it'll help you fine tune, so throttle/steering get a little easier.

I don't know what radio you are using but, see if it has the ability to adjust the maximum throttle.

I upgraded to a Futaba 3pdf which is in your price range.

Using the Throttle adjustment (Throttle ATV on the futabla), It helped me get used to driving around the track without getting myself in trouble with too much speed coming off the straights.

Just lower the value to say 60% then increase it as you become more comfortable with the car.

This will keep you from banging the boards as much while you learn to drive smoothly and stay in your groove.

Driving at full power does you no good in a race if you are hitting boards all the time.

As you increase your max throttle you need to concentrate on learning throttle control. This was a bit easier for me after I spent the time at slower speeds to learn steering motion.

hope this helps

Good point Petzl. Depending on budget and needs, there's a couple of other ways to achieve the same. Use a slower motor. Or use the current limiter on the ESC, if you have one.

Basically, there's no shortcut to the fact that practise is the way to go. But as somebody else said, to go fast, you have to go slow. Meaning dont hit the boards and do hit the right groove.

By the way, I do know the feeling of money which burns in your pocket (I whish it would happen more often ). But sometimes one have to take a deep breath and re-consider what would help getting faster. One thing I've personally down-prioritized for too long, is a setup system. But other good stuff to get is a good spring collection, good / more batteries or a faster steering servo.

What exactly do you mean here? Is the problem one of braking for the corners? Or is a problem of how the car goes round the corners?

If it's braking, that's really one you have to learn to do with your hands alone. You can set a bit of drag brake (i.e brakes at netral) on the transmitter if you want, but that's just a trim function, you don't need a fancy handset to do that.

But driving a car with drag brakes won't help you drive smoothly (unless the car coasts far too much at neutral, like the Brushless motors do). It would be like driving a full size car in first gear all the time - every time you lift off, you'd slow suddenly.

If it's steering, a dual-rate, that limits the lock, can help make the car a bit easier to drive, but go too far and you won't have enough steering to get around the track. You don't really need many other functions than that, so a fancy handset isn't necessary.

The chassis should be set-up for the track before the transmitter.

Default New wheel radio

I have decided to purchase a FM radio and have pick a Futaba 3PK or a KO Helios. Can anyone give me the pros and cons of each? Is there a speed difference between the two? Any feedback will be appreciated. Thanks.

First off, I agree with the other's viewpoint; but we are kind of looking at your situation with a "shotgun approach". In other words, we are trying to cover all the bases.

You indicate that your current controller has "a lot of trim adjustments"; so, I wonder why you are looking at that as being your control issue?

I often run a XXX-S with rubber tires on tight carpet tracks and want to "carry speed" while cornering. Otherwise, I am not sure why you are using foams for a stocker motor setup.

Can you further describe what you are experiencing? Do you feel the power progressively grow as you pull the trigger? Or, does it just feel like...on/off (with no inbetween)?

?.. Foams are the way to go on carpet, more traction and a lot easier to drive, whether stock or mod.


The best thing I've found for my radios is dual-rate, it really helps so that you don't try to turn really suddenly at top speeds and stuff like that.

what exactly is dual rate? how does it function? i have a KO PROPO EX-11 Presto- does the Presto have dual rate? i find the manual difficult to understand. the EX-11 is the first "real" radio i have ever had. all my old ones were cheapos with no extra functions.

Hi Junior,

imjonah is just starting out on carpet by his description. Not sure why he is using foams with a stock motor; unless, it is a recognized race group configuration at his local track.

Using ROAR rules, we don't have a racing class using a stock motor with foam tires; so, my message is definitely from that perspective. Most of the drivers I know learned car control on asphalt (and carpet) using rubber with stock and 19-turn motors and later upgraded to modified motors with foams. Of course, you in Canada may be running under a different set of rules.

I agree that dual rate steering can be helpful to a rookie; however, as I progress, my adjustments have gotten more and more "straight up" (towards default settings).

Maybe, just guessing again, imjonah should be looking at Todd Hodge's rubber and foam setups for carpet tracks available at teamlosi.com? Making whichever changes are required to follow Todd's setups would be a good start towards achieving car control on carpet. Then...practice, practice, practice...

Oh ya XXX-S Bill, I guess I didnt think about the different rules.. our club runs strictly foam tires on carpet. We find them a lot easier to get hooked up, and faster, and they have so much more steering.



sean : Dual-rate simply reduces (or increases) the amount of travel your steering has, this helps when starting out for new racers that just like to crank the wheel all the time. Just play with it a bit, turn it down and see how small of a circle you can drive at low speed.
Low dual-rate means less steering, so while you are learning you are less likely to spin out or flip by turning the wheel too much.
As you get better you can experiment with having more and more steering and just work on moving the wheel smoothly for nice racing lines.

thank you, for the explanation. i have that feature in my radio and use it. the way people were talking about it-it almost sounded like their steering reacted differently at different speeds.

Not to confuse the issue, but there is exponential steering too.

That takes some explaining...
