Yeah i´m back whining again!

How do you fix your endpoint adjustments/servo travel. Aside from putting the rod in some of the holes provided on the arm attached to the servo. And that seldom does the trick completely.

This is constantly a problem with all my "stick" rides. You must refrain from steering full, so the servo doesent bind, or you drag your whole steering arangement apart. And thats easy to do when powersliding on the field.

Latest ride with this problem is my restored KC. But here i actually almost fixed it by shifting holes, but not completely...

Were there ever any stick radios with this "ingenious" feature that seems to be standard on just about any wheel radio?

Mr whino, signing off...

Generally if the servos are set following Tamiyas instructions they

should be more or less correct. having used various stick controllers

over 25 years I've never had this problem, take some time over the

linkages to adjust them properly and you should have no problem. The

only part I have a problem with is Tamiyas servo saver, they are so bad

I never fit them and use a Kimbrough style servo saver from the start.

If the servo is pulling apart your steering arrangement when it binds

then you do need to replace the servo saver with a decent one.

Were there ever any stick radios with this

"ingenious" feature that seems to be standard on just about any wheel

radio?

Most stick radios also come with this feature, everything above budget

level has end point adjustment and/or steering rate adjustment at least, just like wheel radios. In fact

the Futaba FP-2LGX I had in 1984 had end point adjustments as well as

steering rate adjustment.

The difference between stick and wheel radios are very much price

based. Stick radios generally come as very cheap and basic sets, very

basic wheel sets also don't have end point adjustments either. There

are slightly more expensive wheel sets that are more common that do

have one or two extra functions as there is a bigger market for them. Better stick sets cost more but tend

to have many more functions. If you want end point adjustments on a stick

radio that isn't too expensive there are several radios to choose from,

such as the Sanwa Gemini II. Usually they will have a lot more useful

functions as well.

For a cheap fix just add an adjustable rate switch yourself. See here

for a wiring diagram

http://tamiyaclub.com/CS/forums/thread/100833.aspx Fit the

rate pot to the outside of the case so you can adjust it, fit the trim

pot inside as once it is set it will rarely need adjusting again.

As terry said if you build according to manual you should have no problem, if you still do use one hole closer to the center of the servo horn and/or a better servo saver (I use the Tamiya hi-torque ones). Also on sticks you can make some very simple travel limitations by glueing with double tape some plastic pieces on stick gate and mechanically limit its motion.

I've never used a pistol grip radio (apart from on a cheap Nikko

motorbike that my sister bought me for Christmas [:D]) but I've never

had issues with steering binding on a Tamiya model.

Only problem I have recently is my NIB Midnight Pumpkin, which seems to

have virtually no steering whatsoever with the standard setup. 

Might swap for a longer servo arm, if the servo can handle the extra

torque...

Strange that i seem to be about the only one with theese problems.Maybe i´m doing something wrong, but i just dont know what.

As far as folowing the manual goes, im allways pretty fanatic about that actually.

In the case with my KC, i´ll trim some lenght of the rod end that goes in the servo saver. It´s that part that pushes on the side of the servo when using full steering to one side.

I remember setting my LB up, that i had to severly limit the servo travel to avoid the steering to bind. But thats easily fixed with my Futaba wheel radio that i use for all my newly build cars.

I might consider getting one of those more advanced sticks one day. I still like the feeling you get from driving with a stick radio.

Wingnut163, i´m in Europe, so i guess there could be a frequency problem, but i think i´ll "stick" with my stick radio after all.

Here I am to save the day!

This is a radio full of features like you want. I guess you could call it old school [;)]

That is one nice stick radio with everything one could need, old school rules!

Futaba always did make good equipement.

They do have a current PCM stick radio, 3-channel.. it's called the 3VCSuper, but it is more expensive than a 3PK [;)]
