How to use it:

The launch can continue.

About range:

Off this position, the range is significantly reduced.

1. After welding is completed, look at the drawings to check whether the components are installed correctly, especially the electrolyte capacitor polarity, the switch direction can not be installed wrong.

2. After installation is correct, adjust the powerproon on the booster board 28 times clockwise, adjust a few more turns until the end will click, at this time the maximum voltage of the boost output is 28V.

3. Access to the power supply with 2 no. 5 battery 3 or micro usb phone charger 5V power supply (cannot be used to charge the power supply belt does not move), when charging 1 minute later,

Red light on full charge complete, tail loaded shells, quickly press the switch, you can eject the shells, release the switch and automatically charge, when the red light lights up full power,

4. If the gun pipe does not enter the coil, you can first polish the burrs of the gun pipe 2 head, add some lubricant (or peanut oil) lubrication, and then push the coil hard to go.

1 The launch distance depends mainly on the launch angle. According to the ballistic formula, a projectile has the longer range when fired at a 45-degree angle.

2 The position of the shell in the gun tube also affects the range. The best position to place a shell is to keep the head of the shell level with the tail of the coil, which is the longer range, for example.

Note: This electromagnetic gun range of about 3-5 meters, double fruit good, female dust W eight, but from W2 eight Ha.

Warm tip: DIY kit (bulk) to weld their own, installation and production need a certain professional basis and hands-on ability, with detailed drawings, please check the exclusion according to the drawings.

Parameters: voltage DC3-5V,2PCS AA battery or 3V,moible phone charger 5V(please don`t use power bank),range 3-5M.
