Recoil Issues

Is my Recoil Faulty?

The first thing to determine is if your recoil has an issue or if it's performing as it should.

First, you must remember that the recoil is powered from the USB of your computer/Pi and not a dedicated power supply like the guns in the arcade would have been.

The recoil circuit contains a large capacitor that stores up a high voltage charge to operate the recoil at the set strength (which by default is max), and it relies on the USB to charge it.

So as you fire the charge in the capacitor is depleted, if you are playing a slow shooting game you can have the recoil set to max strength, and you will notice no issue.

If, however, you are rapidly firing shot after shot, the capacitor can not charge up fast enough, and so the power will slowly die off. This is perfectly normal and expected behaviour and your recoil is working correctly.

My recoil is working correctly. How do I stop the power from decreasing so quickly?

As mentioned earlier, the recoil dies off due to the capacitor not being able to charge quickly enough. So to maintain a consistent kick, you have to consider a few factors:

• Strength of the recoil: the higher this setting is, the quicker it will deplete the capacitor.
• Firing rate: the faster you fire, the more charge will be depleted.
• Pulse speed: this is the delay between the solenoid being fired; the longer the delay, the more time the capacitor will have to charge between shots.
• Strength and pulse settings can be adjusted in the Sinden software, and you can play with these settings to determine what works for you.

Please note, however, that in the current software releases there is a small bug that stops you from being able to change the above settings while set to the "normal trigger recoil". In order to adjust them set the recoil to "Automatic"; you can then adjust them to suit.

It's a known issue and will be fixed in a future release.

My recoil is definitely faulty. It totally dies off after just 2 or 3 shots!

So if your gun is doing this, it has a problem:

Don't panic if this is the case with your gun; 9 times out of 10, it is an easy fix that you can do yourself at home with basic DIY knowledge. Contact customer services for advice if you are not comfortable performing the following procedure.

So what's causing the issue? For 99% of people, this issue is caused by a deformed spring that had been fitted in the factory when it was manufactured. It's just a case of bending it back to the right shape.

To do this, you must first open up the gun using a Phillips No1 Screwdriver.

• First remove the two screws from the pump handle
• Then all the ones around the gun shell.
• Once opened up, you need to locate the recoil spring
• Compare it to the image below; if it looks deformed like the one on the left,
• Use the metal core the spring is fitted to and pull the base of the spring past the end (see image below). This compresses the spring to look like the middle image
• Refit the spring and close up the gun.
