Hi
This is my first post so i hope it's in the right section.
I have fitted a smoking /light to my tiger one which is working great but the barrel does not recoil when using it on smoke and light. If i turn the smoke and light off then the barrel will recoil.
Anyone know a fix to get the barrel recoil ,smoke and light all working together.

ITS A HENGLONG TIGER 1 V7

Thanks.

Hi! It's 7.1 board?

no, its the 7.0 board

Anytime some functions work and others don't, a good first troubleshooting task is to make sure the battery is taking a full charge and then fully charge the battery. Then check functions again. The boards will be erratic with a low charge and you'll get stuff like sounds but no movement, or only turns left, or turret turns but no forward, etc.

Mike.

Thank mike
3300mah battery fully charged. its a strange one how everything will function but not together.
thanks for your input. i was thinking possible the way everything is plugged in to the board. maybe a re arrange of things.

How is recoil solved in 7.0 because in 7.1 it's a servo.

Tiz a good question. I've got some answers but I'd like to see what the OP shares.

I would open up the tank and provide some pictures of everything, how it’s hooked up, etc.

Can you provide a link or picture of the kit you used?

How are you turning the smoke and light on and off?

Is it gun smoke or exhaust smoke?

A TK7.0 can’t do servo recoil, unless you’re trying to Frankenstein one of the Taigen/Torro servo recoil kits into it. It should still be the recoil that is attached to the Airsoft plunger. Is the plunger still pulling back and shooting BBs?

A la Dr. Frankenstein Here's a video showing the converter used with a TK7.0 board to utilize the Servo for barrel recoil-

Unfortunately the part has been unavailable for some time-

But I'm pretty sure the OP is talking about the HL airsoft "recoil" as they call it just as you are mentioning.

Another question did he jump CN6?
