Futaba FT-3A Boxed Set

Post by MJF »

This one, to me is a real prize. I have only seen photos of the light blue one in past.
I think Futaba also used the same case on their F66 model as well.
This one is missing the small 8 AA cell battery box.
I tried fitting a typical 8 AA cell holder but it is too big
(hard to believe they needed 12V for this!).

The box says that it has a F4-LRS relay-less Receiver in it, however this one had a
a Futaba F327R relay type partially wired to a Graupner Kinematic actuator for a boat.

There is also a loose double sided cube type receiver of unknown make which was loose in the box of proportional
radios.

I am thinking of either converting it to 2.4 if possible, or perhaps leaving it alone and maybe
making up a demo stand with the Kinematic and motor. Does not look like there is a lot of room
inside for an XHT RF module and one of Phil's little boards and have room left for a battery.

For now I will get some batteries and try it out over the weekend.

Anyone ever converted one of these?

Well packaged. If you look close you might see the unknown Rx

You're right, there isn't much room in there but there is just enough. Mine uses Phil's s/c emulator and an Orange DIY RF module. Initially the battery was was a 2s/250mA squeezed in as shown but now is a 2s/450 which sits on top of the Orange module. The antenna is a home brew hidden inside the immitation frequency pennant.

It´s no problem to get everything in.
I built two replicas in original size, one in 2.4GHz and one in 35MHz and both work great.
