RCS Inter-6 Reeds conversion/refit
Postby Phil_G » Sat Apr 11, 2015 7:55 pm

Shaun tipped me off to a nice RCS Inter-6 on ebay recently, I've been after a genuine period 6ch reeds transmitter for a while as the only Tiny-6 I have is my original prototype in its Maplin box. Heres the ebay photo of the RCS as it was auctioned:

It needed a good scrub up and there is some light corrosion, but at least the irreplaceable RCS logo was intact!
The internal PCB was carefully removed and stored 'just in case' :D , bit if a faff as the toggles are mounted directly to the PCB!

The module is a Frsky V8HT which was kindly donated by Alex who has mostly reverted to 35mhz - thanks Alex!
All the heavyweight twin-&-earth Frsky wiring was removed and the bind-board discarded as usual:

The encoder is a standard Tiny-6, in Futaba channel order (AETR). It gives 6 emulated tri-simul reeds channels (3 function), with trim on all channels, servo reversing, choice of two servo-slow speeds and a range check sweep mode:

First job is to clean the old lever contacts, attach the biasing resistors, and wire up the toggles:

At this stage, before connecting the RF module, I add the battery and make sure everything works so far, that we get good ppm and the buzzer is working:
(this is where you realise why we call this the Tiny 6 encoder!

With everything working as expected, the Frsky V8HT module was mounted at the top of the front panel, with the LED discretely under the handle:
Not the tidiest of conversions, maybe I should have let Ron do it for me :D :D :D
I really, really wanted to make this a pristine installation, a showpiece I'd be happy to publish - unfortunately it seems I just don't have the presentation skills some of you lot have and despite my best efforts I'd hardly call it tidy. It works!

Eagle-eyes will notice that I've not mounted the trim button yet - its a temporary one, I've ordered a much smaller 4mm one which will be easier to hide.

And here's the finished transmitter, working better than new and good to go when the wind stops blowing!

And heres the RCS with my trusty Impala at Callow. Just above the RCS logo you can see the discrete
'trim' button:

Looks fine. You made a good job of cleaning the case without damaging any of the text.

It never occurred to me me that the RCS Inter-6 wasnt simultaneous but I was in the shed looking at the original pcb and there is only the one audio-oscillator with various resistors and presets switched in by the toggles. It wasnt simul at all !

This means that on the original RCS Inter-6, you could give rudder, elevator & throttle commands individually, but not at the same time!
So no full up/full rudder spins, no rudder & elevator barrel-rolls, no steering whilst holding down when inverted...
On a rudder/elevator/throttle 6ch reeds model you'd also have no in-flight trims at all. All trimming adjustments were done on the ground with the clevises!

Cheers

And that remains a good discipline ! (Propo just masks lots of bad habits)
