Hello Guys,
I would like to comment that there is a very useful device manufactured by FIRMTRONICS ( www.firmtronics.com/rc-products/digimix-3.php ) capable to mix, procesing and conditioning signals from receivers to servos. It has three channel inputs and two outputs to servos; these outputs can be high or low rate pulse: DIGIMIX 3.

You just need to have some knowledge of basic or pascal program languages; language C is the ideal. The device is a little electronic board as you can see on pictures. Tipical applications:
V-Tail Mix
Gyro gain control
Two servo control with one Rx channel
Mix two Rx channels with variable rate following a third channel
Lights control
Servos sequencer
Another special projects

This device can give a valuable help on your jet planes. I used to mix different signals from Rx and gyros, combine retract and brake with one channel, etc. things that you can not do if you Rx is full or you need some control feedback inside the plane as gyro does.

The device come with a link to a webpage to download pre-rutines to make easy the device's program work.

Check it out.....

Rick.

fantastic... thanks for sharing!

Just had a look and it says out of stock? how much is 499 Zars??

I have three that I used to learn how to program them, and these are working on one plane. Today I asked by two more, and they ask me to wait next batch that should be ready to dispatch next Monday.

Here is a question.

can it take an input from one channel, but operate just One servo when the stick is moved in one direction, and then a separate servo when the stick is moved in the opposite direction? And be able to turn both of these servo's off with the input of a separate channel?

For example.
when switch A is in position 1:
A roll to the left is input by the transmitter. servo #1 moves to extend a spoiler, but the servo #2 does not move.
A roll to the right is input by the transmitter. servo #2 moves to extend a spoiler, but servo #1 does not move.

Then with switch A in position 2: Neither servo #1 or #2 move.


Can it do that?

Yes buddy ! That is a easy program to do with.
You have three inputs. One of those can be analog if you want, so you can add a potentiometer to make any function.

Sawwwwwwwwwweeeeeeeeeeeeeeeeet! now if I could find some body/company who would be interested in making my swing wing controller for my F-14 project, i could have all the bells and whistles in one box

Thomas,
Once I receive the next digimix, I can help you with. I can make the program and send it to you.
But also, the owner of firmtronic can help you with it, for sure.

Thanks man.. I've got a cool idea for a wing controller for my F-14 project that I wish i could find someone to take on the task of designing and building. I may have to send the firmtronic people an email to see if they would be interested in doing.

Invermast,

I have a mix almost exactly as you have descibed above programmed in on my JR 9X. I use it so I can have differential thrust from my PBY Catalina for taxing on the water, so any radio above a 9xII should do it easily.

Thanks
