Here's a complete system setup diagram as we installed it in Smokey. Recently bought an OS 160 two cycle and applied this setup to a test bed for break in and smoke test. Filled the back yard with smoke after about 10 seconds of running smoke.

Swift, I suggest you post this in the products announcement forum. It's against RCU policy to post commercial products in the regular forums. Thanks

which smoke oil did u use?
what muffler for the os-160?
any kind of pre heater?
how much oil/tank do u rec. for the os-160 for 5-7 minutes of smoke?

thanks

RE:

Smoke oil: Been using regular diesel fuel from the gas station. That's diesel making smoke in 11 degrees. Tried the Super Dri once. Can't tell the difference, except for price. The way fuel prices are going though, the diesel price is catching up to the Super Dri.

Muffler for OS 160: Using Slimline #6018 Large Volume Pitts

Preheater: Made my own, 1/8 brass tubing wrapped tightly two revolutions around cylinder close to head.

How much oil: I am guessing 25 - 30 ounces for 5 to 7 minutes. Made a 30 ounce fiberglass tank to fit a Sig Sukhoi I ordered back in July. Going to run this test bed a few more times. Will probably be able to tell you to the second real soon. I would also like the answer to this question. Can you believe how well this thing smoked in 11 degrees?

looks like its smoke very well in the cold have u flown the system yet. are you using a resistrictor to control the amount of fuel you are burning?

Have not yet flown the system. Been developing it since November. OS 160 engine is new. Breaking it in on 10% nitro while testing smoke components at the same time.

Restrictor: What is a restrictor? Using the system exactly as layed out in the diagram above.

I don't think that a .25 will do it. I have an Ultimate with an Os 120 4 stroke a TME pump and I put what they call a remote needle valve in the side of the airplane and I can control the correct amount of fuel to the muffler. I am using Dri Smoke and I get plenty of smoke.

how did the system work 4 ya?

WOW....This is a old thread im interested too

Has anyone ever tried "fog juice" or "haze fluid" originally intended for indoor fog or haze machines in a 2 stroke? Seems like they wouldn't have to be heated as much as oil based smokes and haze fluid doesn't have to be heated at all IIRC.

Try the saito smoke muffler by EJRS they sell here on RCU for about$25-35 and work excellent!! they work with most saito!!

I plan on putting a smoke system in a new plane with a DLE 30 gas engine. I want to know if there is an advantage in using a special muffler (ie: with a coil inside) and if so, who makes one

I am interested in what would be the best fluid? The diesel sounds good. Also the "fog juice" What are the experiences? Of course, I want to try to clean mine up some. I am currently using the Bennett's stuff.
