Heng long PzIV won't shoot

[Grey Knight]

Hello all, I've got a issue with my PzIV , everything works but the gun push the button on the TX and nothing happens. I've had it about a year and a half and only checked it when I first bought it,( it was new in the box) I don't like dry firing anything so I don't believe I tried it ,just drove it around a little. Took it apart ( marked all the plugs ) did some cosmetic mods,stowage bin, long barrel, mantlet etc, then set it aside waiting for paint(,it's a 6.0s bye the way ) About a month ago my son came to visit and wanted to play with the tanks.I also have an HL M4a3 so we start messing around and no boom.I've checked the connections,wires, motor and gears everything seems to be alright what am I missing? HELP...Chuck

did you turn on the firing switch under the turret hatch?

[Grey Knight]

Tiger6 hello,the only thing under the commanders hatch is the plug for the IR

[Tiger6]

Ah, you didn't specify that its the IR version - Can't help you with that I'm afraid

[Grey Knight]

Oops,it has both BB and ir but I don't plan on using the ir option, I did remove the motor for the firing and it works just fine with a power source applied,gears also turn freely by hand so I'm thinking it might be the TX or rx somehow...Chuck

The 6.0 doesn't have the switch under the commanders hatch as the BB gun is no longer wired with the elevation unit.
When you say press the firing button are you just pushing the 1 button on the top right?
As you are suppose to push both buttons A + B for the BB gun to fire

I just ran a Google "Advanced Search" with the terms

Manual
"HengLong"

and came up with loads of possibilities. Maybe one of these has the newest manual.
