I don't think this has been covered in a previous post so I'll try here. There has been lots of chat about HengLongs new Ver 6 MFUs and the loads of functions they provide from the transmitter but despite reading the v6/v6.1 manuals and the flysheets on the same I'm still lost when it comes to firing the main cannon.

Firing the BB bullet is simple enough. Showing the aiming light looks simple too, providing you fit the light, but how do you fire the lR system, get the adjusted hull recoil and firing sounds WITHOUT operating the airsoft gun? It's not the BB shell I'm worried about as you can just not load any (but it would add safety) but l don't want the delay in firing or the airsoft noise. I intend fitting a recoil /flash /smoking barrel when available so don't really want to start disabling function that future fitting may require.

Any thoughts anyone?

You can't fire the IR without firing the airsoft. At least that's how it is on mine.

Boooooo....
I was just about to ask the same question doh!

That's no problem, now there's at least two of us looking for the same solution! We've been searching for ways to turn off the hull recoil, now done for us, so make enough fuss and you never know....

I seem to recall there used to be a bb gun switch fitted beneath a hatch in the various turrets so I'll explore some of my earlier models to see how they were wired and what affect they had. I'll let you all know BUT if anyone can add anything, please do

On the rx18 they had a button on the TX that you could push and you would get cannon fire and track recoil but nothing would shoot. If they have that in the 6.0 I still haven't found it but it shouldn't be difficult to add.

And I just ordered a T90 so next week my JP will have something to battle against. Different time frames, but we don't care.

The airsoft safety switch wiring looks like this, GJ: This is for Taigen, but it was essentially the same at that time.

...and another useful diagram- again Taigen , but the HL had the same switch wiring... Click to ENLARGE

From those diagrams (thanks) it looks like the switch turns off the power to the red firing warning led and the airsoft motor. It would be easy to add a switch to do the same job but l wonder if it would negatively impact the firing associated functions, like sound, barrel recoil, flash and smoke but IF those are all controlled within the MFU then it could be straight forward. I'm still waiting for a recoil barrel with flash and smoke to be available as an upgrade.

(Edit) I'll try fitting a switch and report back asap

Evening all
In my v6 tiger I unplugged the bb unit from the mfu . On the back of the bb unit is a microswitch trigger which is also plugged into the mfu. Remove the microswitch from the bb unit. If you then cut the 2 wires from the microswitch trigger and join the 2 together. What you get when you press the 2 buttons on the transmitter to fire the main gun is. Instant gun sound with track recoil and I.r shot.
You can also wire a superbright 5mm led to the place on the mfu where you unplugged the bb unit and you will get a Barrell flash as well
