New Henglong T-34, no recoil.

[DanV]

I just received my new Henglong T-34, tested everything, but there is no body recoil when it's set to fire the ammo, but there is a body recoil when it's disabled and you get the cannon sound and recoil. I'm guessing it has something to do with internal wiring but yet to open the tank up.
Also I feel that the power of the firing seems pretty week compared to my other Henglong tanks. I noticed that the barrel itself seems maybe a little loose and I can turn it, indicating that the O-ring may not be seated properly. Does this seem right?

Can't comment on the airsoft issue as none of my tanks have BB units installed anymore.

The "body recoil" is controlled by the MFU settings. There are 3 strengths of recoil if I recall correctly and then completely off (so 4 total). It sends a quick jolt of electricity to the motors to create the "rocking effect". The amount of current sent to the motor determines how strong the "recoil" is. The body recoil is controlled by this setting highlighted below:

Thanks, I have tried those adjustments. But the body recoil works only when the BB firing is disabled when not firing the BBs, but doesn't work when it's activated and fires the BBs.
