NEW UPDATED AUG 2018 VERSION HAS ARRIVED

Hop-up is the back-spin put on the gel balls to increase their range via the Magnus effect. A Hop-up  puts backspin on the gel balls reducing the air pressure on its top side.

Hopup works amazing.

# Also tested to work well with spring upgrades of 1.2mm and 1.3mm
