Hello folks,
Hope you can help. If I take out a BB gun and install a modified Heng Long recoil unit, will the tanks still emit a fire sound.
I'm a bit confused as the upgrade package states you need the BB switch to on for the tank to emit its canon fire sound.
Does these means its triggering on the micro switch mounted on the BB unit or simply a "load" needs to be active (which the switch would remove if turned off).

Scoopey, the microswitch on the recoil is what activates the firing sound and hull recoil. This need to be "closed" to trigger the sound and hull recoil. I am not too sure if I understand what you mean by "load" but it is just a contact from the microswitch and once contact is made, the spring pulls the firing pin back to the starting position and the microswitch pops back to open.
