ICS Split Gearbox Die Hard Test

This video wants to prove the durable structure of ICS Split gearbox using M120 spring and an 11.1v, 2000mah lipoly battery.

Though I’ve tested an ICS unit without problems using a much stronger Techpro 190 Spring with 11.1v 2000mah, just make sure to change ICS’s stock soft piston body to a more durable one. =)
