How long would this guy last = w=?

just found this thing while browsing…
has anyone used them before? or have any idea how reliable they would be?

Possible internal mod for what this might be goin into:
M90 spring
metal piston + piston head
18:1 metal gears
stock motor or high torque motor

This would look cool for a short time till it went pop, crackle or bang. I’d stick a gopro on there and film the destruction.


Sounds like a plan lol
