Building the BATTLE TRUCK..
 

Ok I'm trying somthing new, I'm building a battle truck “the ultimate battle truck” to be exact (tee hee) :intello: and I was wondering if you guys could help me (??)..

Here is what I’ve got!.

(live Rocket pods!) :oops: (Got to love this hobby!) :yipi:
#1. Can you recommend or point me in the direction I need to go to find a firing mechanism for my rocket pods?
#2. Do you know how I can set them up to fire after each other 1bang Right side …2bang left side and so on with only a sec or two between side / rounds..
#3. Can you recommend any packing I can use to hold them while drive / bashing ? I was thinking cotton or wax ???

(Also!!) :whistle:
Does anyone know where I can get a full cage roll bar for either a GorillaMax or a X-Ray truggy ??. (I need to make gull wing doors) that raise up exposing the rockets pods then firing.. I need a strong frame to work from and bolt things to..

Here is what I’ve got so for..

Thanks for your time team..


P.S.
I’ll post pics of its 6mm (Simi auto) paint gun soon as well… :wink:

“Lincpimp”. (I found my setup last night), I should have by the end of the week…..

This is funny! Glad you found the setup last night. I look forward to seeing the progress.

As for roll cages, there is a company that makes a bunch of tubular cages. I think they are called rc solutions, but I am not sure... I have a tmaxx cage floating around somewhere...

lol this project is going to be hilarious! :lol:

I can't wait to see the finished product. :yes:

:eyes::eyes::eyes:

ummm can you gime time to build a bunker:na:

One of the easiest ways I can think of to fire sequentially is this.

Use a Rx output to drive a servo that set up to trigger a momentary switch. The momentary switch, then gives power to a low RPM motor direct wired to a battery pack. Couple the output shaft of the motor to a rotary switch such as this:
http://www.newark.com/40M9999/switch...0dp45-01-1-ajn

Tie the positive output of your battery (6-12V, 2S lipo would be great) to the single pole on the switch. Then, each output from the switch goes to a single leg of each one of these:
http://www3.towerhobbies.com/cgi-bin...?&I=LXF569&P=D

Then take the other leg of each of the of the ignitors and tie it to the negative on the battery.

Now, once connected, you control the servo actuated switch with your Tx, triggering the motor to spin which, in turn, rotates the rotary switch sending voltage to each of the ignitors in whatever order you have them wired. The speed at which they fire is simply controlled by the RPM of the motor you're using to turn the rotary switch.

Good luck with it. We'll definitely need to see vids!

Agreed. This should be a fun one to read about. :intello:

Wow, Shaun. I didn't realize that information I provided last night was gonna go towards something so destructive :surprised:.

I shall watch this thread closely...........

Looks like a fun project!

Ok I think I found the Frame ?? :eyes:. can some please verify / do you know if this will work on a GM or X-Ray Truggy ?? I just need the center section so I'm pretty sure I or MetalMan can make it work. :whistle:

P.S.
Thanks for the pull Lincpimp..

Metalman..
Don’t kid yourself Sir, the next time you take the lead from me will be your trucks last :lol::lol::lol:


Skellyo..

Thank you Sir – Huge HELP… much appreciated.. :party: :yipi:

Rusty, Rschoi, TexasSP & Andrew..:intello:


P.S.
I’ll also be needing a 6 channel radio any thoughts anyone ?? :neutral:

Hitec laser 6- so many knobs and dials, perfect for controlling the doors and firing mech.

I like the rotary switch idea, why not add an arm to that switch, and just use a servo to move the arm, with a linkage? You would need a radio with a selecatable step 3rd channel, like the m11. I may have to give that idea a try...

Whoah another project Shaun? Too bad those rocket engine are not allowed to be shipped outside US...and there are not many distributor of those material here....I wanted to put it on a heli and fire some on my neighbor :lol:

I know there are RC relay switch that can be triggered using one of the servo channels but not sure how to go about the sequence firing...

I think you will need a pan and tilt setup:

http://servocity.com/html/spt200_pan___tilt_system.html

I've looked at those pan & tilt things before- predator shoulder cannon anyone?...

Any of course it must have remote video!

http://www.rc-cam.com/rc-cam4.htm

Thanks Neil and James.. I’ll look into the radio’s tonight.. :party:

Quick recap: :whistle:
• Got the frame (check)
• Got two 6mm paint ball guns firing 20 rounds (check) weighing 4lbs
• Got the articulating firing mount (check)
• Got 8 rockets and 2 set of pods (check)
• I got the firing system recommendation (check)


Need the following: :eyes:
I still need help with the deploying the rear smoke
I still need help to figure out a way to keep the rockets in the pods while bashing the truck
I need to find and buy a 6+ channel radio system
I need to buy another 6mm paint semi auto paint gun


I'm pretty sure I’ve figured out already know how the doors will work (drew if up last night). It will be basically controlled like Linc ref above (linkage and servo).. I'm a little lost on the rotary thing (sorry).. :oops:

I plan on bolting the rocket pods to the inside of the gull wing doors, that way when they raise up so do the rockets.. OOoo I can see it now… LOL.LOl..:wink: depends on the weight ?? TBD

My 6mm Semi Auto paint gun only holds 10 rounds (bummer) but its all electronic so I’ll have the options of using either a crude linkage system or I’ll pay BrianG for some programming time.. I even (I think) figured out a way to install two of them, so between 8 rockets and 20 rounds of paint I should be just about good to go.. LOL.LOL :intello:

Another thing I still need to figure out is deploying smoke out the rear (some camouflage and confusion screen ).. :lol::lol: I know planes have something like a smoke bottle but I'm not sure I can use that on a truck.. So again (any help) is deeply appreciated.. :yes:

Arct1k
GREAT PULL and at $45 bucks a pop I got two (gave me more ides / Just incase the gull wings fail) Thank you SIR… :yipi:


Should be a total blast at the next so-Cal bash… (literally!)

Smoke...

Ignition is the only issue... But not sure why you couldn't use an electric igniter...

http://chemistry.about.com/od/demons.../smokebomb.htm

PS I think you can do a google on e-matches to look at ignition options.

Yep, I definately plan on watching this build. We need somthing out of the ordinary like this once in awhile here on rcm...

That's cool Arct1k.. :intello:I don’t know how you find these things but you’re the Man.. :yes:

Although I'm checking the plane sites for a canisters type, if planes have them there has got to be something I can buy ??. :neutral:

Thanks for the throwing them out Sir.. Please keep them coming..:yipi::yipi:

great project.

My question goes to rocket flight path with no fins to aim them, or will you be doing something like that FFAR's (folding fin aerial rocket) that they can mount to attack helis?

Thanks TD / just trying to keep up with the (Lincpimp's of the world) :yipi: :lol: :lol::lol:

Hay DickyT,
I’ll be using a folding fin system.. I got a heavy duty air cleaner and plan on using the flutes of the filter as fins for the rockets, they fold onto the rocket and then slide into the pod. In theory they should expand once the rockets leave the pods.. In theory..:wink:
If they need help re-xpandning after they leve the pod then I / "WE" will need to think of somthing..:mdr: Hoping the above works.. :yipi:

lol this reminds me of a project i wanted to do when i was 10, boy is great to be an adult, you get to do those things you dream about.

When i was a kid i build a rocket launcher with a wired launch control panel i used very thing copper wire forming a spiral,(resistance) then let true some amount of current to fuse the wire this ignited the "rockets".

also you might consider an auto destruct mechanism lol

cool project.:yes:you have to get this done before the bash,i have to see this:lol:

Here you go:

http://www.regin.com/rcsmokeacc.html

even easier! TowerHobbies! http://www3.towerhobbies.com/cgi-bin...?&I=LXFT71&P=7

I would find some sort of thin spring metal that can be used to make fins. That way they can be folded up and will hold the rocket in the tube. Problem will be finding something thin and springy, but not too strong that the rocket will not come out of the tube when powered.

On the door opening front, have you concidered these?

http://servocity.com/html/servo_actuators.html

They have much smaller versions coming soon.

For smoke, might want to look into this: http://www.tmenet.com/products.htm#ssp
It already has the ability to interface with an R/C signal natively.

For general electronic switch needs, you could try these: http://www3.towerhobbies.com/cgi-bin...P?&C=MBZ&V=EMO
They turn the radio pulse signals into actual switched outputs.

You can get servos that do not have a specific range of motion - they act as winches instead. Tower has some but not sure what they would be called...

NOTES FROM OUR TECH DEPARTMENT

Smoke-Equipped Planes are rapidly becoming more popular with the show team-
type demos that are all over the country. If you don't want to mess with
compicated plumbing, you need a smoke cartridge like the Smoke-Riter.

FEATURES: Produces approx. 3 minutes of dense grey/white smoke No need for plumbing to exhaust, messy fluids, or residue clean-up Mount to fuselage by using a clamp (not included) in marked locations Only. Light fuse to begin smoke reaction.

INCLUDES: One Smoke-Riter Cartridge w/Ignition Fuse

SPECS: Length: 6" Weight: 6 oz (including light blue wrapper) Diameter: 1-1/2" Fuse length: 2-1/2"

COMMENTS: Smoke release holes must face ground. Smoke is TOXIC. Avoid Prolonged Exposure. Clamps to hold cartridge to the fuselage (try a hardware store).


we dont want our fellow forum'ers to die :rofl::lol:

You can make you own smokers by mixing sugar and salt in the appropriate quantities with water, then leaving it to dry in whatever shaped vessel you require. You could have a smoker that easily lasted 5minutes+...

Yep - Instructions were posted further up - I like fire!

I missed that, cheers dude. I havent looked at the cookbook for a while, so precise instructions escape my memory....

Strangely enough, I have a couple large yellow smokers that I have plans for myself, involving my truck- great minds think alike...

Don't drive it near the college or on passing out day... You might get visited by the men in black!

I didnt see anywhere the point of this Shaun, did you join a bot club or scale war club ? Or just for no reason other than to have what seems to be the coolest toy ever ? You win either way

hmm, iv been trying to look at sequential rocket ignition systems but cant find any, you could see if you have any friends that are electrical engineers. Its actually a pretty simple circuit, but i just cant remember...and my notes from my last EE class are alll loong gone

Saltpeter, sulfur and sugar is what we used to make smoke bombs as kids. Copious amouts of smoke!

Forget the sulfur. It just made it stink:

http://www.wikihow.com/Make-a-Smoke-Bomb

You could try the smoke system they use on drifters:

Thanks GUYS..
 

Hay TB, that's what bottle rockets are for anrt they :intello:


It is fun being an adult, but we have to shave like everyday thou :lol:
I like the suggestion about the thin wire (thank you!) that might come in handy..

NO... :no: there will be NO auto destruct button, I'm moding my GEVO for this and no way in hell will I intently blow it up, but if it does it on it's own, my only wish is the Video is running

Thanks Cornolio.. I don’t think it will be ready by the 19th (sorry) but i should have gull wings and pods done by the 19th.. :yes:


Thank you / much appreciated Sir.. :yipi:


You got me thinking about this one, I know I’ve seen something before, maybe it will come to me when I or if I sober up :lol:

Thanks for your comments Lincpimp..



Hay Neil..

That's cool... to bad they don’t have the 10 lbs one out now.. I was actually thinking of something a lot simpler, once I get the frame and build the doors well see how much it all weighs and if a JR 440oz servo will work. If not then I know what my plan "B" is..

Thanks for the find / pull.. I was hoping you would post some of the goodies you know of.



Thank you Brian.. :intello: love the general info, I really didn’t know that servo's could do all that.. It should make my life / build go much easier..

Way to much info on the smoke, now it's hard to pick just one system, it's not easy being me.. LOL.LOL.LOL..



Hay BB16..

Nooooo we would never want that, just their trucks LOL.LOL..


Hay Jay "what the good word" for me its new cool project. LOL.LOL
No, no new clubs, I just wanted to build something no one else has, I've completed all my RC's and I was looking for a new challenge. So inlue of starting a heli or sub build i decided to build the first fully functional RC battle truck..

Thanks for the kind words sir, if I / we (the team) can pull this off (rockets, fully auto paint balls, smoke, etc) it should be huge and blast to see..

Have a great on Jay and thanks for stopping by and checking it out.. You might want to keep an eye open for further updates in a week or two. (IE) once I get all the parts I ordered..


Hay Andrew..
Thanks for the help.. I'm hoping that between BrianG, Skellyo, Arct1k, Neil, Linc, you, Jery, metalman, gee, TexasSP, Jhultz and few others I / we will be able to pull this one off.

Have a great one Sir and thanks for posting, please don’t stop!..

Shaun.



No sulfur.. but may shooting oil out the back (just to help complicate things) might be in order.. LOL.LOL..



LOL.LOL that's cool.. but not even close to the amount I'll need, I plan on hitting that button and blinding everyone behind me in a cloud of smoke.. :na:

It should be ready by our November bash!, I'll show you how it works close up then. LOL.LOL.

Have a great one BLR...

Shaun.
