For sure if your trying to use one TX for multiple toys they are great. Think what PantherG and I have always noticed is mainly during IR battling that tankers will have
some hiccup during a battle with a setting or forget which model is which or forget to check endpoints, expo, mixing after a bench test. Then they become cannon fodder cause their fire button isn't working or elevation is reversed, etc. Also makes initial setup pretty tough with the newer aftermarket boards especially if you don't know your way around your TX.
