well this all started when I got a RC heli just before guy fawkes night helicopter + rocket = cool
well i did start that but soon realized i would have to buy another controller to fire it on command then i had a vision (actually i tripped over my RC nitro car then it came to me RC-carmageddon so with some parts that i had sitting round i figured i could do this for only the price of the rocket

Step 1: What You Will Need
>>>>>>>Remote controlled car (working would help)
>>>>>>>4 Channel or more the better controller and receiver
>>>>>>>Higher capacity battery's (I use a heli lithium cell 7.4v 800mah)
>>>>>>>2X RC servo
>>>>>>>TOOLS and MATERIALS:
Screwdrivers small and large phillips and flat head
Aluminium off cuts
Step 2: Lets Get This Party Started
You want to start this step by finding a location to meet you tilt servo, as you can see in picture 1, I used some original mounting holes for convenience but you could use part of the chassis to mount your servo further forward its all up to you.
you will then need to fashion a mount out of your aluminium or whatever you have around.
Step 3: Turret Construction
You will now need the two servos.
start by removing one of the servos bottom casing, when the casing is removed look at the construction of the servo for some free space inside for the head of the screw and drill a hole in each side of the servo and make the one opposite the mounting hole big enough to fit your screw driver in to tighten.
attach the casing to the second servo and tighten then put the first servo together, after that attach to the mounting on the car that you attached earlier.
Step 4: Nearly There
you will now have a platform that will pan and tilt but you need to hook up the radio gear and some kind of switch to control the launch
Remove the 2 channel radio from you car then find the accelerator servo and those offcuts of metal and
fashion a switch so that when you apply full brakes the switch closes, then make yourself a wiring loom witch will take the power back too the turret for the iginitor attach the loom then you ready to put the reciver into the car you will need to make sure the throttle and steering are on one stick and the turret on the other to make it easier to drive run the wires check operation make sure the servos arnt hitting anything this will reduce servo life
Step 5: Cannons Away
to make my cannon I used the outside of a pen blue tacked to the top of the servo,
to make the ignitor i used a match head with ni-chrome wire soldered to some normal wire and wrapped and glued together, then you can attach to the fuse of your rocket, personally i wrap blue tack round the ignitorand insert it into the pen tube and add a little gun powder and a bb there you go a cannon
Step 6: Finished
There you go now you have a fully fledged battle platform go away with the ideas that I have given you and better it maybe a camera, laser pointer and the list goes on but watch this space for updates to this design and more that I'm sure will come around.
Thanks to all
