Can i still update the firmware if my is from Japan???

Where'd you pick it up? I can't find an online retailer.

3 or 4 weeks ago when Tower had them in stock. I bought another 4PX, got this one on easy pay with the $75 off coupon. I think its like $154ish for 3 easy pays.

I don't see why not, the firmware notes did not say anything about being region specific.

Bonjour, désolé suite a la mise a jour de ma radio elle ne fonctione plus ...
Depuis la mise a jour elle n'arrive pas a faire la calibration de l'accelerateur, elle tremble.
une personne du forum a t'elle la 1er version ?

Car meme apres plusieurs essais de la v1.1 rien a faire.
Donc pour le moment je pense que seul la solution de remettre la v1.0 va corriger mon probleme.
Merci d'avance a vous

How do we up date

Hello ,
My radio has a problem since v 1.1 calibration , and tremble even handle to neutral.
It remains 1.0 you downloading whatever part?
Or if the person, if possible, give me the email .
Thank you to you
PS: Sorry for the google translation

The PDF that can be downloaded described the update procedure, You copy the firmware Futaba folder to the root of the SC Card and power up the 4PX while holding the End button and off it goes.

I would guess your SD Card must be formatted in FAT32 format.

Just starting my set up. Noticed I have way more steering to left then to right. I centered servo any ideas ?? Thx

Are the steering links the same length? Are the endpoints on the radio set? What car is this in? Really not enough info provided to be much help.

Yes all the basics are done right. It's in a X-ray t4 Never had this kind of prob

You used what feature to center the servo??

Make sure your trim and sub trim are at zero.

Put your servo horn on.

Use the sub trim to put the horn at a 90deg angle (if that is what your instructions recommends).

Adjust the steering turn buckle (the one coming off of the servo) to centralize the steering rack.

Set the steering rods and camber links to equal lengths. It's not import if the toe-out is not spot on at this stage, it will be re-checked again later.

Adjust your steering end points to maximum throw. They should read the same figure each way or with in one or two.

Set you toe-out and camber and then re-check your maximum throw again.

Use the D/R to reduce your steering throw during a race, not the steering end points.

Who's offering the best deals/discounts on the 4PX this week?
