I have just purchased a Picolario Talk and trying to figure out how to fit the 3 way switch required to change parameters. My Tx is a Multiplex Royal Evo 9, I am aware that you guys with 4000 and 3030 Tx's already have large blank slot to fit one in already. The Evo can be assigned to use such a switch but I am unable to fit it in the slim body of the Evo. The only one person I am aware of is Chris Garrod. he fly's his Glider using a Royal Evo's Tx. Alternatively is the switch really necessary ? Is there anyone out there with an answer to this problem either to be able to set up the Tx with its existing switches or not use the switch at all. I would be most grateful if anyone can help.
All you need for the Picolario is a spare 3-way switch or proportional slider so that you can select the 3 functions: off/vario and altitude/same with battery voltage. I'm not familiar with the Evo 9 - do you have such a switch available? Otherwise could you link the Picolario via a y-cable to another function - such as flaps or wheel brake?

I have the Picolario connected to a Y-lead with the retract on my Dart 17. With the wheel down, the vario is off at the lower position of the 3-way switch on my Cockpit Tx. In the middle position the wheel is up and the vario working. The upper position calls up the altitude to order. It's such a useful function on the Picolario that it's worth the effort to get it working...

I'm new to the Picolario but have it working nicely with the Mpx Evo 9. I put the picolario on a Y-lead together with the tow release via a three position switch (switch "L" in my case) as follows:

Down: Release is closed and Picolario is off.

Middle: Release is open and Picolario is in normal Vario mode.

Up: Release remains open and Picolario gives instantaneous altitude.
The only minor inconvieniece was that I had to extend the servo travel on the tow release slightly to make it work the Picolario, but it doesn't have to be anything like +/1 100% for the Picolario..

Thanks. I have tried out the Y lead and it works well. What an instant way to solve a problem Thanks again to you all.

Glad you've got it sorted, it really is worth the extra effort to have the ability to switch the 'incessant racket' off!. And to check the batt voltage and height!.

One other idea which I've done with my 4000, but don't know if you can with the EVO is to use the throttle trim for the vario, on the 4000 it can be disconnected electronically from the main function and used for something else, I don't need to trim the spoilers/ brakes so don't need the trim slider. So at the lowest position its all off, middle vario, top momentarily gives me a height and voltage readout. Works for me!.
