ok, l`m having probs understanding how to fit a HL Jagdpanther recoil unit in my HL Tiger 1.
At present l`ve taken out the airsoft unit, directly wired the recoil unit in place, used the same microswitch and have the barrel recoiling, but what do l need to do to synchronise the recoil with cannon sound...must add l`m a complete beginner with electronics, the wiring diagrams may as well be in Swahili

Can any of you guys explain what l need to do to next pleeeease..my heads spinning
