1/32 Moebius Flying Sub

Do you think Kevin McCloud's throttle jockey might work? It mixes the 2 motors with the rudder servo. It is a very small device as well. Is the second servo for elevator control?

[PaulC]

Bob, that's a good question. I already have one of those.

BD, when you say servos (plural) are you talking about independent control of the thrust nozzles? I'm curious if that is necessary. Don't Teskey, and others, run their boats with the nozzles ganged together?

[JWLaRue]

BD,

At least we're not talking about trying to do this with the typical Japanese radio platform...

Will definitely appreciate the schematic!

Paul,

I think BD is talking about being able to execute a roll maneuver via the 2nd mixer......?

Hmmm...aquabatics?

Kevin may correct me on this but the Throttle jockey won't work.
It is meant for steering. Your other control is up/down.
Jeff is correct as I use the two mixed servos to roll the sub.
Granted as I have become a weenee and put more stability in buy adding more foam to the wings so it won't roll much anymore.
DonO's wife Pattie uses the Teskey method of only 3 channels.
Two for differential throttle steering, and one for the up/down thrust deflection on both nozzles hooked together.
I run mine on two separate servos with the mixer.

[bigdave]

Jeff, you still have a 9 or 12 EVO correct?
The 7 will not do it. BD
I am sure the Profi will but I am not proficient at it yet.

[JWLaRue]

BD,

Correct....a pair of Evo 9's. I also have both Profi variants.

btw: did I tell you I found someone who has replacement LCD panels for the Evo's?

-Jeff

[bigdave]

No
You neglected to mention that. BD

[JWLaRue]

That's why I asked!

Mike Ridley (http://modelradioworkshop.co.uk/) is who I got them from. They cost £44.00 + shipping. As they don't show up on his web site, so you'll need to e-mail him with the request.

If you know the display type, you can often find new LCD displays on ebay for very little money.

I recently replaced a large display on an old synthesizer I own. The original display was backlit with an electroluminescent foil, and this had dimmed to the point where the display was illegible. New foils are available, but they have a finite life. I found a new display on ebay with a LED backlight for only a few quid more than a replacement foil would have cost, and the LED should last for decades. The display cost about £17 delivered.

Colour me "fashionably late" to this party...
What is it that you're trying to do? BD is absolutely correct that the TJ is meant for mixing "steering" commands into a pair of throttle signals, but it's all just software.

Are you looking for a mixer to control vertical motion of the two discharge nozzles - together for pitch and in opposition for roll?

[bigdave]

Pheww!
Color me relieved you agree!
That is what Paul is after. If a radio can't do mixing you will need something like one or two X mixers.
Depending on if you want roll control.
We are lucky in that our radios (My Multiplex and your 9Z)can do multiple mixers. BD

Why mess around trying to find something that might or might not work? If I can get a factory replacement, that's what I'll always go with.

Agree again on the utility of radios that can do many mixes, but there is some fine print that comes with that... To be able to make the right signals a pitch controller needs to be located before the mix, meaning you would have to choose between mixing in your Tx or using a pitch controller. (Actually, there's even fine print with that statement because you could actually mix in your transmitter and put one pitch controller on each servo, but that's just crazy talk!)
