I hope I don't get flamed for this...
But I just thought it would really cool to put rockets on my heli.

I had a look at pen sized flare launchers and I figure you could rig something to the aux channel on the Tx so it trips a relay that fires the rockets...

with a heli mounted mini cam might make for some awesome footage.

has anyone done this kind of stuff before ?
I'd love to see other peoples ideas for it.

There was one site
I took it off my bookmarks because the site was all screwed up. A 30 size heli the dude put a laser pointer and small BB gun on it. Would be fun!

I use the laser pointer attached to my camera platform. I fly the helicopter close to a wall and film the image of the laser on the wall. This has proven to be an effective way for me to dial my camera platforms.

I have given allot of thought to both bottle rockets, Flares (flare gun) and BB guns.
However if you are going to invest the time, I am thinking a Platform that has pan and tilt, controlled by a second camera operator, a mini wireless camera looking straight down the scope of the BB gun.
The camera mans image would be that of looking through the scope. The helicopter operator could focus on steadying the helicopter, while the camera/weapons operator is plucking cans off the fence.

Don't read your AMA card before doing this, they/most are not really excited about this idea.

Sounds pretty dangerous, so of course I would never do something like this, let alone film the whole thing.

Thanks, Flyboy

Cool
Great idea! You could tape a site onto the monitor for accuracy! Or go one step further and use a virtual reality headset!

Saw a site where a guy flys using the virtual reality glasses and a blanket over him so the only thing he can see is what is coming from the onboard camera. He has someone outside the blanket connected via buddy coard.

I only have a piccolo now which I don't want to fire anything from. One guy has setup a unit on one that fires the plastic BB's. That would be good to torchure my cats with.

I am going to get a joker. That would be large enough to hold onto something substantial!

took apart a pen launcher and
have decided that the spring is a little too powerful to mess around with.
there are many ways I can imagine it can be locked back and then released but I'm also investigating solenoids hitting the flare directly.

i.e. dispensing with the body of the flare launcher (the body only exists to hold the flare in place and to provide a guide for the plunger/spring which shove the firing pin into the back of the flare.


oh and btw that guys web site with the bb gun on the concept 30 is here

bb gun heli

solenoids and electromagnets..
after some playing with google found

http://www.solenoidcity.com

they have most every solenoid you might want - I ordered an S-66-100-26.5

which should work like an electronic firing pin - I will post pics as and when everything arrives

Better yet, tape a bullseye to the virtual reality headset, and try out for the Darwin awards.

I got some vids off of rr of a guy launching bottle rockets off of his heli while hovering.

You couldn't be more wrong with this type of thinking. When it comes to ballistics, thinking like this will get you, or someone else, killed.

curious about this...
I'd love to find out more to make it more accurate...
but I've fired a bunch of different weapons before (granted not from an airborne platform)...and the recoil on the mini flare is practically negligible...
I am still finalising testing the platform.
The Force of the plunger is dependent on the voltage across the solenoid and is currently (with 9V) not quite enough to compress the percussion cap - but is enough to scratch it.
I'm assuming if I file the firing pin sharper and increase the voltage I could get the pressure high enough to cause it to fire.

will find out shortly (I was unable to get detailed specs and tolerances on the percussion caps from any supplier).

are you suggesting there is a danger inherent in

(a) accidental firing (i.e. what we used to call a Negligent Discharge in the army) whereby the heli is pointing at someones head and the flare fires...
(b) misfire (where the flare is half-fired - or rather not correctly fired and as such becomes dangerous and unstable because the percussion cap has been weakened but not sufficiently to fire it making (a) more likely
(c) correct firing but too much recoil causing heli to crash
(d) correct firing but explosion of heli

or all of the above.
I'm trying not to do this whimsically so I would appreciate any and all pointers...

thanks

why not buy a fully automatic airsoft gun?? all you would need to do it hook it up to the skids, and have a servo on the trigger. The airsoft gun is only 30 bucks....servo is 15....to me, thats what i would do.

Flare Firing
Actually nickybee, I am specifically refering to your comment in requards to the purpose of the launcher:
i.e. dispensing with the body of the flare launcher (the body only exists to hold the flare in place and to provide a guide for the plunger/spring which shove the firing pin into the back of the flare.
.
"....the body only exist to hold the flare in place and to provide a guide for the plunger/spring....."

This is a very dangerous outlook/conclusion as to the purpose of the body of the flare launcher. Flares, like all propelled projectiles, are constructed the way they are for a reason. Flares are loaded with powder, and primer and a projectile. In this case...a flare. If order for that flare to gain altitude and perform its' intended function, it must gain enough momentum to overcome gravity. To acheve this, the powder is used. This is loaded into a brass case, and a primer is loaded into the bottom of the case. Under "normal" usage, when the flare primer is struck, it ignites the powder. As the powder burns it expands, causing the CASE to expand and seal the rear of the case against the barrel. This forces pressure to the front of the case, and when the force is sufficient to overcome the friction of the projectile against the barrell, it is then propelled out the end of the barrell.
.
The danger is in thinking that a cases' ONLY purpose is to "...hold the flare in place and guide the plunger....." The pupose of the case is to seal the end of the barrell. If you do not make your launcher "meaty" enough to contain the pressure of the expanding case, and maintain that hold until the projectile is expelled from the end of the barrell, you are setting yourself up for an uncontroled explosion. Ballistics, shells, etc., when used properly, are known as controled explosions. That is why they work like they do. By removing, or just using anything as a "barrell", you have created a situation in which the "controled" explosion is no longer predictable, or controled. That is where the danger is.

.
You sound like you have some knowledge in the ballistic end, and not just the area of "firing" guns before. My main consern is that someone less knowledgable will read your post and make assumptions about other forms of ballistics and really get themselves hurt. I would hate to hear something like this happen.
