Help needed

[SNIPEOverkill]

Sorry been about for a while what with work moving and the general daily grind not had much time for the truck.

 

my Truck is the Tamiya Scania r620 and if it is fitted with the mfc 03 unit. I have been having trouble getting all the functions to work and stay working.

 

but got it back out again tonight and I have a question I have had trouble setting up the lights and sound just so happens today one of my jobs was out a model shop so I asked the bloke inside and he said I should get the futaba attack  4ywd 2.4g transmitter. Question I have what I have seen of the futaba is it is only 4 channel would this allow me to have all the light and sounds working and any added lights to work. My current one as pictured above is 8 channel. Any help would be appreciated trying to get pasted this issue so I can finally get it finished and lacquered. Then it’son to the trailers.

@SNIPEOverkill the gear you have should work, don't buy a new one yet unless someone on here with knowledge of it says so. You could try the truck section, or change the title of this thread to needing help with an MFC. There are a lot of members on here who have trucks and will be able to help (I'm not one of them). @Mad Ax any ideas?

Ok thank you

I think the model shop owner was concerned about the trim sliders on your transmitter - they are digital / one-step-at-a-time switches, not sliders.  To change the MFC functions with 4 channels, you need to be able to slide from 'central / zero trim' to full left / full right / full up / full down - you can't really do that with your transmitter.  Or, you can, but you'll be there for a while reaching full trim to activate the function you want, then toggling back to centre trim so you can drive.

I've set up the MFC using the Futaba, which works well, and also using a FlySky FS-i6 transmitter, which is programmable - i.e. I can configure one of the switches to change the endpoint on the 4 axis channels.  So I trick the MFC into thinking I've given full trim in order to get at the functions.  What I mean is - then the switch is in the Down position, the sticks have a range of -100% to +100%, and when the switch is in the Up position, the sticks have a range of -125% to +125%, so the MFC thinks I have applied full trim in whatever direction I move the sticks.  The mode for this on the FlySky is called "sport mode" and it's designed for sport aircraft, where you'll have the "normal" mode for take-off, landing and cruise, to make the plane easier to control, and then a "sport" mode that gives greater control surface angle so you can turn tighter and do other fun aerobatic stuff.

Your transmitter doesn't have a programmable screen, but from what I can tell, it does have a way to program it from an app.  What you'll want to do is configure it like a sport mode, so you have 100% travel when the switch is in one position, and around 120% when it's in the other position.

I don't know if you can operate the MFC functions with additional channels, I've never tried that.
