RC Nerf Tank

Step 9 Modifying the vulcan

I needed a way to pull the trigger remotely, and like the turret I'm going to use a servo.

For anyone wanting to build remote controlled projects servos are the way to go. You can modify them to spin 360 degrees or leave them stock if you just need a back and forth motion. You can get a RC transmitter, receiver, and servos fairly inexpensively if you shop around a bit.

I mounted the servo to the gun with a small aluminum mount and tapped threads directly into the nerf plastic, it seems to hold up okay and the servo easily pulls the trigger.

where did u get that trigger mechisim and how much was it

[travis7s]

Its an RC servo. It is a Hitec HS-311. You can get them at local RC hobby stores or at online places like servocity.com for $9.

what about home hardWARE

[Jedrokivich]

You can get 'em cheaper at hobbyking.com. Their cheapest one is about $2.
Great shipping prices too.

The servo that activates the laser is actually from Hobby King, I just happened to have lots of the Hitec ones kicking around.

relay = 1.50
servo = 15.00

[travis7s]

Yes but how are you going to send the fire signal to the relay? The servo has circuitry to use the signal from the receiver. Also you get can servos for <$5 these days.

what servo u use

[sbracco]

You should've wired it to the gun. The servo was a good idea too though.
