Ok, I installed the new computer app, the new phone app, and I flashed the newer firmware in the board.
The board is much, much better now. The Elmod fusion Pro does not only have 24 user sounds instead of the old 8, but the are also more user functions configurable, and also the elmod base (not pro) now can play those 24 sounds too!
Depending of the radio you have, you dont need any 3 position switch or knob. It is just a matter or programming the radio and sending the required signal to the Elmod board. Months ago I did this two videos that, sadly as usual, gathered no interest. People willing to play user sounds, or wanting to learn how to use advanced radios seems to be a rara avis in forums... But no probs, Ill keep sharing things.
Do not take those videos like a walkthrough, because that radio has been modified to far beyond most of human capabilities, and it wont match any existent radio in the market. (I must say that I followed the openrcforums tutorials to be able to achieve it, I did not invent the wheel. Joao and MikeB, I cannot thank you enough) what it is important is to see the signal I am sending and what is the tank doing. And also as you can see I am not touching the sticks for anything.
I will make a new video with a similar setup for those 24 sounds and extra functions, but I need some time (that might vary from weeks to months) for it.
Regarding your board, connect it to the computer, save your profile. Then update the app, then the board, and finaly load your profile. Everything will keep working exactly as it did, but now you can add more things to it.
IMHO at this moment, this is by far, the best board available in the market. Still ultra expensive though.
Enjoy.
