Anyone else using the new Futaba 4YWD?

[1985 kenworth]

I have great success with 2.4 specktrum dx radios with my builds and i still use the futaba am's for some of my builds... they work fine, i got one thats 4yrs old however why would you want your truck to be that far away from you.are you running it on.a large track of some sort.like jack says unfortunately not all radios are compatible with the mfu unit.some on this forum use airtronics too

Hey guys thanks for your replies

This new unit is basically the same as the 4YF, but molded in black and marketed as
compatible with the mfc-01 and mfc-02.

Tamiya actually offer a "Full set" tractor truck kit with this radio.

I have emailed Futaba America but they are not familiar with this radio as it's an overseas model.

I only bought this unit as it was marketed as a 2.4 unit that is compatible with the Multi Function Unit.

1985 kenworth: I have a reasonable sized driveway and I like to hit the top of 3rd with a 55t
every now and again, it is pretty scary when something you've invested a fair amount of time and money into starts trying to do its own thing

Thanks again guys for your help

I have a 4YF running my truck and it experiences the issues you describe almost to a tee.
The blinking reverse lights and sound always happens.
The lazy right turn signal still happens too but I've minimized the engine shut down by placing the right vertical trim just south a notch or 2.
When you do move your trims do it slowly and not a quick zip to max.
When functions won't work check your left stick centre, things won't work if it's out just a bit. Once I found the proper centre I marked with a fine paint marker.
To make the hazards work, once you move the right stick up and return to centre, give it a small pull down and return to centre. I bet your hazards will work. To shut them off, repeat process. Try it and let me know.

Funny thing is... Some days the truck works perfect and never misses a beat! I spent 3 days at the Indy show last year and never had a problem! It ran great at the Clifford show but other times I have nothing but constant shutdowns
It's really weird.

My wife's truck has a older Airtronics VG 600 FM radio and that thing is awesome! never, ever glitches, all functions run great no problems at all and no visible antenna on the truck. I attached the wire to one of the stacks ( chromed copper pipe ) and have more range than my eyes can handle

Hey Mario, thanks for your post.

I have unfortunately already reinstalled the AM set so I can't check what you asked,
But if I didn't push the trim all the way forward I could sometimes get the hazards to work, but even then, sometimes they would just stay on full time etc.

Before I uninstalled it, I did take a quick video, some of it shows the errors I posted above and usually things like the two trim shut down etc doesnt work but did in the video. I am positive it pretty much has a mind of its own lol. I am going to wait until my tank turns up on Monday, try it with the DMD unit, otherwise I might have to contact the seller and see about returning it.

I have a MFC-02 (for the tamiya highlift) and a Futaba 6J. I had to use the dual rate switch to make the blinkers work, and I also use the dual rate switch to separate the high beams and the horn. It took some time to figure it all out, as I was not aware how to use the new radio functions, or how the MFC-02 is suppose to act.

I think I invested over 6 hours in the last 9 months, but is it ever sweet to have it all work!

[Berman]

Thanks Acadieman. I have heard of others using dual rates on other radio sets with success setting the rates to approx 65% and 100% respectively, then just flicking the dual rate switch and moving the appropriate sticks. Glad you got your highlift sorted.

Well not conclusive right now, But after a few emails with the reseller I bought the radio off, it seems that there was a running change recently with the multi function units to coincide with these new 2.4ghz sets from Futaba.

Apparently the box of the new multi function units has some slight colour/text differences and reference to the new 2.4ghz systems whereas the older still has reference to the AM 4VWD units.

And after picking up a Leopard 2a6 last night with the reference to the AM set inside, I find it unlikely this unit is going to work with a tank either.

I have emailed Futaba Japan and am waiting for a reply.

So options for me are:

1, Replace both multi function units with newer models, replacing both AM radios with 2.4ghz Futaba sets and also with the tank (lol I doubt anyone would consider this!).

2, Buy another 4VWD set for the tank, just roll AM style, risking runaway models and party like its 1999. (Possible)

3, switch all 3 over to an aftermarket 2.4ghz set with multiple memory and receivers (like the Airtronics set a few of you guys use) and run a dual rate setup and sell off the Futaba sets. (Probable)

4, buy 3 hobbyking 4ch 2.4ghz sets (as these work) and sell the Futaba sets (probable).

Any suggestions and feedback appreciated
