Spektrum DSM dodgy neutral
 

So I am setting up a Futaba 3VCS with Spektrum Pro DSM module and SR300 receiver in a 10th buggy.

I have turned on the transmitter and calibtrated the speedo and this is working fine.

Problem is if I turn off the transmitter the speedo neutral is about 20% forward.

Anyone any ideas what that's about? and how can I get it to sit at neutral when the tranny is off?

I believer the failsafe function of the 3vcs only works in PCM mode and as I am using DSM I am in PPM mode which does not seem to have a failsafe setting???

I've used a 3vcs with various other modules for years and never had this before.

So only happens when u turn off ur handset first, is there a fail safe for the spectrum unit itself

set speedo up, the rebind the receiver to the transmitter, where ever you leave the sticks will be fail safe. spectrum has its own fail safe system set when binding

at the min you have bound the rx/tx and then set your speedo, so the fail safe is in the wrong place

Thanks Mark... it would appear that I originally tried to bind the receiver using the AUX port which is clearly not correct, the second hand receiver and module/tranny were apparently already bound which is why I had connection. I reset the factory settings prior to me trying to bind the system, this must have upset the original bind.

Cheers dude, I probably wouldn't have re traced my steps without that reply, or if I did it would be after much faffing about. All sorted now :thumbsup:

guess how much faffing I did to find it lol

HAHAHA!!!
