Spirit System

Wondering what most of you do that are using the Wifi module.
Do install on heli or just plugin as needed?

I can see advantage to install initially, but then wonder how many times you need it after model is tuned.

Thanks.

I have four Spirit units... So, for me, it was cheaper to buy only one Wifi module, and plug it when I need it.

I have a permanent install on a 470LM
