Omega fuel and brodak dope

For many years now I have used Omega fuel with various oils added depending on the engine it was to be used in. Locally it is so much cheaper and the only brand always available in various percentages. My engines always have lasted well and performed well. This has been with Sig dope mostly as well as some monocoat and some croma clear and lets say I am happy so far ,even though I do realise that many have expressed disfavor with Omega publically. Now this year I am using my first plane completely done in Brodak dope. The dope was wonderful in all ways. Now something bad has started to happen. The bottom of my beautiful blue and white plane is turning pink in areas where the exhaust collects, around the pipe etc.What a bummer. Ill go out this afternoon and try to get some powermaster if I can though it is going to cost more, But I am depressed to realize that I have about seven gallons of Omega at home Beware it could be the Achilles heal of Brodak dope.

Keith,

I think both you and your new Saturn will look real good with pink bottoms.

Randy might be able to suggest some really trick clear that you could apply to bottom of fuselage only, that reducing the damage and minimizing weight penalty.

I used Omega for a few years after I started using Brodak dope. I have not had any problems with discoloring. Seems odd that your dope is
changing colors.

Keith,
My "Super Tucano" is also showing the signs of Omega pink against the Brodak white. I've though that it was raw fuel blowing out of the tank, but different venting styles (including muffler pressure feed) have done nothing to stop it. It will rub out with polish and elbow grease. But who wants to do that after ever flying session? Another fact,..my plane is also Brodak clear coated,..so what gives?

Two things I forgot to mention; Mine is clearcoated of course to allow for the buffing I do; and also; I have added some Klotz which even deepens the pink tint more than the stock fuel. Dan..... to mention my pink bottom is hitting below the belt. I bet my pink bottom flying my Humongous can beat yo old cellulite bottom flying your Zilch X at the regionals. You know your beautiful Zilch cant land worth a darn. Keith

Tony,

That's one beautiful airplane. What is it, your own design or some modified ship.I would get a little upset too if I saw my finish changing colors on a ship like that.
I assume you have clear coat of some sought over the color and trim. That should keep the the ship from staining. You might call Omega and ask them what kind of dye they use in their fuel and tell them what your experiencing and see what they have to say about it.
Let me know when you get an answer from them.
This is not a problem I've ever heard of from others. I have heard of staining, but without the color stain, from the amount of Nitro in the fuel melting some of the clear if the content is over 10 to 15% high.

Best regards,

Bob,
Here's some SSW archive links related to the Super Tucano. It is a scratch build but there is nothing currently on paper in way of plans (although I do have the start of the fuselage profile sorta started). Last year I started to draw up some pictures that were slated for CAD conversion by Bob Kruger, at his request. Sadly, as one of my post relates, the time crunch around here has only gotten worse, with my wife's return to work last Aug. and me pulling Mr. Mom duties with the two young'uns. Can't even get an ARF together for cryin' out loud. Anyway, scan the links and see what history relates.

Hi Keith,

You probably already do this.

If you do not want to do any more painting, put a couple coats of wax on your plane. I use car wax. Wax often. Protects the paint & makes it shine.

But all that extra weight!

That's not limited to Brodak dope. I can recall Red Max doing the same thing to a wide variety of paints back in the day. I always requested mine with no red dye. It dyed K&B superpoxy pink, too.

Yes, and watch the red dye in Marvel Air Tool oil as well. This is an excellent oil to use for after run oil in your engine, but should not be used for such things as oiling hinges or the like. (Some people put a small bit of oil on the barrel of their hinges before gluing them in. Vaseline, or similar is a better idea. The red dye in the air tool oil can and will get in and under the paint and then bleed through.

This just in from Morgan Fuels in reply to related question:

From the deck top of Steve Morgan:

By the way your plane looks great Tony.
The culprit is the strong solvent characteristics of the nitro. It is
attacking your paint which allows the dye from the fuel to get down into the
layers of paint. At this point in time, I’m sorry to say we haven’t found a
descent remedy. The red dye we use to color the fuel is very aggressive on
white and yellow colors.
I’m sorry not to be more helpful, but I would like to use one of your
pictures for our future Morgan Fuel Gallery if you don’t mind.
Sorry for the inconvenience,
Steve Morgan

My info request:

Steve,

First things first,...who's the girl in your "Contact Us" page photo? Very
nice in deed!!!! Say hello for me No worries as I'm happily
married,...BUT I'M NOT DEAD, ha ha.

Question: I'm flying control-line models and am using your Omega blends up
here in Canada. No troubles to speak of until this year,..and even this is
not really trouble. But,...my model, finished in Brodak white dope for the
most part, is turning pink from the exhaust residue. All of the finish
is Brodak materials, and it's even clear coated in Brodak dope. The area
down stream of the exhaust gas residue (underside of outboard wing outboard
side of fuselage, outboard side for stab, etc.) is tinted pink for some
reason. What is it in the fuel that gives it it's pink color that may be
effecting my finish? First time it's happen with your fuel use. Never seen
this before with Brodak dope. Picture attached of model (pre pink). Thanks
for any info you may have.

Tony

For what it's worth.
