It's about 6" to the centre of the button, hope it helps!
Thank you and yes, very helpful. US has none in stock so couldnt answer my question for a build idea.
That puts the switch hole sitting over a very long battery pack and chassis.

Unless I go single cells or 14650 pack I gotta save this beast for a different build.
Looks built for spinning. I think anyone wielding a Guardian or Bellicose one handed deserves some kind of recognition. One in each hand... hurts my wrists just thinking about it but its an awesome thought.
Coupler time!?
