Hi Adriano,
the stroke of the push button is a bit longer, on EVO. Purpose is, you can not as easily actuate it accidentally.
There are ways: you can stick 'something' to the bottom of the plastic punch inside.
Finde something which gives you the ease of control you want, but which does not make it actuate the pushbutton inside by just looking at it, or by compressing the case when held tightly, with both hands.
We also have different such punches, with different thickness of the bottom end.
They are included in the tool set 05577, but we can also send some separately.
E-mail me at service (at) mikado-heli (dot) de if you like.
Kind regards
Eddi
