Fellow FG'ers, As many of you know, I have had a long standing ad here in the engines forum that I have kept alive with what I have felt was useful information, comments and general discussion. However the ad thread has become long and information is a little tedious to find.
I don't want to be perceived as 'that guy' top posting just to stay on the front page, So if anyone wants to talk smoke, I feel its more respectful to move the conversation over here and close my current ad thread.

My products will continue to be available as before. I expect to have a running website which is in the works launched later this summer.

In the meantime, purchases can be handled via PM's here on the forum or by email.
I can't thank members enough for your patronage and interest in arguably the new smoke standard.

Now we can see if there is enough interest in smoke to support a dedicated thread about the subject of smoke.

Thanks Crankcase!

I run your nozzles in my PAU Viper. They are amazing. The volume of smoke greatly increased and the usage of oil decreased when I moved from plain nipples to your nozzles. I would never use anything else!

+1
I have them in my MXS104 with headers & cans

I have little or no residue on the plane and amazing amounts of smoke.

Getting ready to order another set

PM me the info if you are doing the longer Jet nozzles. I need that.

Yup we do Atomizing turbine tubes in 10" 12" & 14" lengths
Standard orifice size or High Output orifice size.

Rough sizing:

One standard orifice for up to 100N to 120N
Two standard orifice for 140N to 210N
One high output 180N and up
Two high output 210N and up

I might not have all configurations on hand ready to ship immediately, but I should have something that would work.

I have and have used your nozzles, I currently do not have smoke on a plane.
I am building a PAU Viper with GP 123 do your nozzles screw directly into the stock GP 123 mufflers?
Thanks

They might. 10-32 thread size is pretty common for pre-tapped smoke ports that your muffler is supplied with. However, I have seen a few mufflers that were tapped for 8-32.

The biggest issue that I am seeing is that factory smoke ports are designed for smoke fittings that inject oil in straight line. These fittings are either the crimped copper tube or just a palin old pressure nipple. Because my nozzles spray at an angle, once inserted in factory located holes- the spray is not directed in the proper location for the best smoke.

I always suggest running my nozzle loose as a test so you see how the spray pattern is directed. Then you drill and tap a new hole in the proper location to get the spray directed across the exhaust port opening ar about a 45deg angle. just not up and into the cylinder of the engine. This will give the best smoke performance.

Because of the design, the position of the spray depth can be adjusted some by threading the entire nozzle further into the hole. Or it can be backed out which allows for some degree of adjustment before locking the position by tightening the lock nut. The nozzle can also be rotated slightly and locked into place with the jam nut, Some modelers are nervous of spraying toward the engine or upstream into the exhaust flow. By rotating the nozzle, you can spray which ever direction you want. It still works, but the smoke and unburnt oil blow by will be increased.

And here is a better pic of the spray pattern and spray angle side view.
This better illustrates the advantage of relocating port locations.

Thanks for the illustration.

No problem.
There is another product offered called a no-weld kit. These are adapters that allow fitment of nozzles to header pipes for header and canister setups. Just drill a hole and bolt them on. Here's a picture of the kit contents and a sample shot of the assembly. Kits are offered in several sizes as determined by your header OD size. Instructions are included.

hey crank

i have been using my nozzles i bought from you for a year now. i havent flown my smoky edge yet this year, but i can say that your nozzles are great! Amazing, actually. Good idea to start a thread!

Sub.

Very interesting indeed!
What exactly would be the advantages of going with these nozzles??


How much is the rate of consumption improved over like a DA standard smoke fitting?


How difficult is it to get the positioning correct for the nozzle.
Is it a set distance away from the standard position of a DA muffler smoke tap hole???
is there like a tutorial or something?

2 lines for a twin?
What is the effects of running smoke through canisters?
Cost?

Sure, I've posted answers.

if your not atomizing, chances are that your using a standard pressure nipple, or a pinched piece of brass tubing that is crimped to give you two jet streams, or pinched down flat to make one thin flat stream.

The benefits of atomizing are: Very small orifice size for decreased consumption and increased time per tank. (subject to crimped nozzle design) Very small droplet size, & expelled fluid velocity is slowed substantially promoting faster more complete vaporization of smoke fluid. This minimizes inherent muffler cooling and unburnt blow-by resulting in an oil covered airplane.

How much is the rate of consumption improved over like a DA standard smoke fitting?
I have done testing with a crimped pinched DIY brass nipple compared to my nozzles & run times are more than double the run time per tank. For example: 16.9oz water bottle test with same wide open pump speed and the pump purged of air will yield an average time of 1:57 run time versus 0:56

How difficult is it to get the positioning correct for the nozzle.

Instructions suggest running nozzle in the open with water for example to get an idea of the angle of spray. This will get you in the ballpark for planning locations.
is there like a tutorial or something?
I can post my instructions.
