Homemade Smoke System
Hey,
Right, Idea!
Okay so i know some guys dont like much smoke... but i love it haha!?
Soooo, just exactly what can i throw into the muffler to make smoke?!
How would i get it in there...

Has anyone got any pictures of some out there?!

It would be good to see and intresting to try out

-Jvr

Ps, hmm, maybe even put a little fragrence in there to

If I understand it right you need to inject some special liquid into the hot part of the muffler.

None of this is first hand knowledge. I read-up on it because I was going to try it too.

Buy a smoke pump and add a nipple to your muffler. Maybe use a header tank for the smoke oil.

Smoke systems work best with smoke mufflers, but you aren't likely to fit one to a heli. So you will have to risk ruining your muffler or header finding a good place to drill and tap a hole.

There is a fine line between not enough smoke oil and too much. Adjust flow rate acordingly. Also, smoke oil burns best if pre-heated before getting to the muffler.... Not sure how you could invent something for that.

INTROSMOKE

This one is mostly home made.
I was having trouble with this URL but it might work for you, It was working fine for me last week.. If not try googling for
INTROSMOKE.

Also there is this system you can buy.
Mastersmoke

3D plankers use the mastersmoke one a lot. theve got some videos you can download aswell.

As far as the preheating goes you want to wrap copper tubbing around the header or just the hottest part of the muffler ,then injest it as close to the head of the engine as possible so that the liquid gets maximum heat time before exiting the muffler.

Just use Magnum fuel, you won't need a smoke system.

And I was going to suggest Cool Power 30 and run the engine just a bit on the rich side! That stuff smokes enough to smoke out the pilot on occasion.

On the bright side, we never have to worry about biting insects when we are flying!

another way to make a heat exchanger (pre-heater) is to rap the copper tubing around the head of the motor, and when the fluid goes around in the tubing and around the head of the motor, it will act like a radiator to a car and it will cool the head.GDay

Hmmm,
Well it would seem theres a lot that can be done to head up the system, but it looks like that will all have to be homemade lol...
That should be do-able and looks very intresting, but what about the pressure issue?!
Is it possible to use the pressure from the muffler to push the fuel out?
Surely bleeding presure out the muffler into the tank and then through a one way valve?
If the smoke fuel is mounted higher on the fraeme than the muffler... maybe the pressure from the muffler will even out and the oil will syphen through
But then you wont get to use much in the way of tubing to pre heat the oil... *sighs*.
I guess i'm wanting to get away with it without shelling out for a pump or using engine pressure from the backplate....

Ohhh?!
Now with a scale model i wonder if it would be possible to make a finer pipe "mesh" very very very close to the head/muffler etc in which the smoke can vaporise and then be lead to certain parts of the heli without having to deal with the exaust...
surely it will give a much smoother flow of smoke hmmm

Its a whole new window of fun tinkerability *grins*

But yeah, thanx for all the info people

Lots out there, just gotts find a solution to this pressure issue

It HAS to be do-able without a pump or backplate do-hicky...
I know i'm going to be scratching my head at work 2moro... and my day off sunday, and work the next day etc etc
*grins*.

I think most smoke systems are based on atomising oil.
As Sipper said, Magnum30 does a pretty good job.

smoke
I have tried putting a coil of bass tubing around the head and injecting smoke oil into the muffler, it helps, but glow engines just don't smoke as well as the gassers. Gassers produce a lot of heat in the muffler. But, if you must try, wrap the head and put a coil of bass or copper tubing into the muffler and give it a try for yourself.
