Speedo problems!

[Dangerbus]

Hi all,

I have a Futaba FF3 TX mated to a Futaba 1024 PCM receiver, I am currently running 2 channels plus the switched 3rd channel in my Tamiya blazer through an old futaba electronic speedo.

My problem is that the speed does not have a linear reverse, it is either all or nothing. So to get round this problem I purchased (via ebay) a new electronic speedo that has a one-touch set-up, the speedo is unbranded (ACME) and has come from Hong-Kong, it is basically a copy of a Futaba MMC330 but my problem is that it doesn't function with my FF3 radio gear. If I plug the speedo into my old Futaba attack radio gear then it works ok.

Any ideas or advice greatly recived.

Cheers

Hi, It sounds like you have the throttle curve set wrong on the FF3 try resetting the curve to straight by selecting the 'res' function on the curve setting.

I don't now why a speedo would not work with the FF3 i have a couple of FF3's and a 3PK all running with many different speedo's including two MC330's maybe the plug was put in the wrong way or wrong channel?

Its possible you have the mixer enabled and doing something strange, anyway good luck with it

Disco,

Thanks for the reply, I tried what you suggested (RES) but the speedo still doesn't respond, I even reset the TX back to factory settings but no difference.

I can't think of anything else to try.

Thanks again for taking the time to reply.

Does the servo(s) work normally when you have this "new" ESC plugged in ? It could be a polarity problem with the connector on the ESC to the receiver.

Have you tried the ESC with another radio or in another car? Maybe the ESC is faulty.
