The dark art that is the Tiger recoil system

[Allan Shannon]

Hi. Colleagues

I bet most of us have had the issue where you just cannot get the recoil to work as intended with the cam system. Previously it work ok, don't know how but it did(luck rather than skill).I had to take turret off and unfortunately snapped a wire on the turret recoil motor, manged to repair it with an amateurish soldering job. I now cant get the recoil to work as before ,the gun recoils twice before stopping, so every time I engage recoil the cam go round twice then stops. Any Advice would be welcome especially if you work with Armortek, please tell me your secret for getting this right!

Also what gauge wire is used for the turret motor?

Cheers Allan

Hi Allan

At one point I was having the same problem (two cam revolutions) and during a discussion with another forum member it was suggested that this problem is due to one of the microswitches. One of the two microswitches is activated by a servo. The servo arm needs to activate the microswitch quicker. So I suspect the adjustment needs to be in that area to avoid the twin revolutions of the cam.

I can't confirm if this is correct because I eventually changed the system to arduino control and a stepper motor.

Hope this helps.

The timing is absolutely critical, but the forces involved seem to move the switches over time.

I found it easier to adjust the stopping switch - the one not activated by the servo - so it stops earlier than it should, then tweak it gently until the roller bearing stops about half an inch from the step in the cam. Any closer than that and you risk it no activating in time and getting a free spin.

Did you deepen the cam divot at all or is it still factory?

[Adrian Harris]

I haven't adjusted the divot.

[Allan Shannon]

No I have not deepened the cam divot.

Hi Allan
I too had this problem which I discussed with Vince! The servo actuated switch must open AND close before the cam has completed it’s revolution. Then you can adjust the cam operated switch to stop where you prefer... as Adrian explained
Hope this helps!

Do I physically adjust the servo arm to achieve this or can I adjust it within my radio setting, which I know nothing about. The system I have is the Spektrum DX6.

Hi Allan

Probably a combination of both servo arm and switch, not the radio.
The servo arm needs only to touch the switch enough to open the circuit that operates the recoil motor. The servo arm then needs to immediately reverse direction to close the switch before the cam has completed one revolution. Once you’ve achieved this, you need to adjust the other switch that’s operated by the cam to stop the motor, ideally, in the divot. When you grasp the idea of how the system works... it’s quite simple!
