Building the BATTLE TRUCK..

[Finnster]

Ha ha. I saw that swivel joint thing at servo city Arct1k linked a while back and it gave me ideas of doing the same thing. However, I wanted to mount the rocket pod onto the swivel and have the gun hard mounted onto the cab frame with a camo Hummer truck body. I didn't think servos would hold up to small arms fire too well, but then again I was dreaming up the greatest YouTube RC vid of all time, with a panning paintball gun firing at a victim Radioshack car, then nailing it with exploding rocket. Then I realized I was 31 with kids and my wife would F#$%#g kill me if I made such a thing. Oh well, lots of luck to you.

I know ServoCity has non-centering 360* servos (continous spin) for helis that would work great w/ the turret. I was thinking of using Estes mini rockets. The small ones that use the 1/2A series engines. You could go soviet ICBM style and use a big engine bastard too. lol. Rocket ignitors are really easy and useful for setting all sorts of incendiary devices off with.

I also had a ton of estes rocket engines as a kid. I took a bunch apart and kept the powder to make my own fireworks (CO had strict fireworks laws, you may have seen the giant smoke snake episode of South Park and I know what I mean.)
One of the best was the powder in a cardbord container mixed with cut-up match heads. The powder would explode making a great big smoke mushroom cloud with flaming match heads flying out in all directions. These could also be fired into the air with a slingshot and detonated midair with great effect.

Rocket engines also found their way into all sorts of projects and toys. Rocket tyco RCs, a rocket RC boat, even a rocket Pinewood derby car. That had a bigass D engine too. In its one and only run, it set the landspeed record pinewood derby cars, as well as highest flying PWD car after it hit a sloped curb down the street, and lastly most obliteratied PWD car when the engine exploded to deploy the chute (there was none.) It rained matches and toothpicks. lol
[btw: Booster stage engines can be used to ignite other incendiary devices in the upper parts of the rocket. I'm just saying.]
Good luck and don't kill anything. Don't aim that thing at children or pets.
