I just got a 3pks off ebay it looks brand new the guy said it had only been function tested but anyway, i put it in and i am having trouble with my steering I have full left steering and only like a quarter right. i am using a jr 9100s in my B4 and its in HRS. i cant find out how to change it back or if the radio just has issues.. any help would be much appreicated THANKS

Check the e.p.a. in the settings

Look here on around page 45 http://manuals.hobbico.com/fut/3pks-manual.pdf

Take you servo horn set you're trim and subtrim to 0 and make sure the dual rate is all the way up and then reinstall you're servo horn and adjust you're endpoints and that should fix it

There are two thumb wheels below the streeging wheel. One (the upper) is the strg dual rate. This may be part of the prob - the setting for this is on the display screen - top right corner (D/R : 100), it should be 100.

If its not end point adj (epa) either or in combo, try a model reset from the menu. This radio has 3 levels of menus and something can be set in a higher menu that you might not see because of the way menus are laid out. Model reset sets everything back to defaults so you can adj from the starting point.

You def need teh manual with this one....

I do have my manual. i will try all of this hopefully it will work thanks for you help...

ok so i did all of those and still nothing. When i go to my steering expo and i look at the graph, it has the center bar where it should be, but my steering is way to the right of that. and i went into the adjuster and i think when you not touching the wheel it should be somewhere around 0 but mine is all the way up to 60% just sitting at neutral so im wondering if it is the radio its self. does anyone know how futaba is on repairs i dont have a warranty is it even worth sending it in?? or is it fixabale. thanks for your help

When you went into the adjuster. Did you turn the wheel all the way to the left and all the way to the right. Then push +/- to execute.

Sounds like you have a bad pot on your wheel. It needs to be replaced. 10-15% is typical for TXs that have some time on them as the pots will 'drift' off center after being used for a while. You can try to center it with the Adjust feature but 60% is really too much to work well. Send it in and service will replace the pot for you and check everything else as well.

Have you tried it with another receiver/servo combination?

I did turn the wheel all the way left then right and hit both buttons and it said err, err, ok, then it said unsucsessful. i have tryed it with a different servo, but not the recever i was going to do that but i figured the problem was in the radio itself cuz even when i reset the whole radio i still have the same problem. i personally think it is the pot like you were saying im going to go to the track tonight and see if someone there can help me with it. if not its off to futaba. i dont have a warranty with it does anyone know around about how much they will charge for that? Thank you all so much for you help...

You can try calling, they might be able to give you an idea over telephone or try emailing. Its on pg 4 in the manual, phone and email addy.
