Has anyone tried this to combat the rusting problem on the rear bearing on the OS 50? Good,,,,bad,,,,,,or whatever.

Ok....new question.

Has anyone ever used this stuff in any of your engines?

I've not used that product, but I have used multiple variants of these very low viscosity petroleum distillates that are sold as rust inhibitors. I've be disappointed every single time. Here's the deal. For good rust protection, preservative oil needs a little viscosity to coat and THEN stay on the bearing. These very thin products coat initially when they are applied, but they can't often maintain a thick enough coating to resist rust getting started. Even with the best fuels, it takes a good product to resist rust setting up housekeeping in a high humidity environment with lots a steel parts inside your engine. I've been uniformly satisfied with the use of automatic transmission fluid in engines without silicone based pump or pressure systems and YS Performance Ultra Oil for those engines that have such fuel systems. You'll get a million opinions on this matter, and MUCH of it has to do with where you live where you have to store your models. I'm just telling what has been shown to work for me, and I know because I pull the backplate and apply the oil after each flight session (I'm anal as hell....).

Thanks, Dr Ben. I guess it can't hurt.

BTW, I keep my stuff in the house in the A/C.

A/C is a good thing.

As soon as you can get the stuff in your engine post flying day, the better off you'll be.

YS Performance Ultra Oil

Does anyone know what this oil is composed of? Silicone based?

My OS50 is a bit over 2 year now, about 300 flights.
I changed the bearing once, after about 120 flights.

But theres no evidence of rust in any place inside the engine at all.
Looks shining new everywhere, so did also the changed bearing.

I fly with home mixed fuel, Sunoco methanol, 18% oil(Aerosynth3) 20-23% nitro.

I never use any after run oil or other detergents, just kill the engine with the TH-trim and leave it. I have my helis in my garage, its warmed to normal 'inside-house' temp.

I've been spraying a bit of air tool oil into mine if I'm not flying for an extended amount of time. I then crank the engine with the plug out just in case I squirt too much in--avoid hydraulic lock. I would guess this stuff sticks to the metal.

must have been a downdraft

Back when I had more expensive machines, I used VCI foam in a "heli bag".

You can also buy an aerosol to "fog" the bag for longer & quicker protection.
They are good for a year or two.

I think the most important variable here is where you live. I've had tons of bearing problems and my last Hyper lasted 4 months with 50 flights on it. I'm rebuilding one of my hypers now and I'm installing a pressure fitting on the back plate for oiling. I tried positioning the nipple near the bearing, but there is not enough meat or real estate on the Hyper case for the install.

I think Dr Ben is practicing the only full proof way of oiling the bearing. I'm just trying to avoid pulling the backplate after every flight.

Chris,

If you lube through a backplate hole, have the model more or less on its side and inject the oil pretty slowly so it runs down into the race of the rear bearing, and then turn the engine slowly by hand about a dozen times. If the model is inverted when you inject, the oil pretty much goes right up the crankcase journal and never gets where it really ought to be. Some will interject here that if you spin the motor over a few times, it'll distribute the oil. It does indeed, but the resulting coating is sometimes not thick enough to block the rust from starting, especially with a light viscosity preservative oil.

Don't for one minute think I like pulling the backplate to oil the bearing. It's a PITA. It is much LESS of a PITA, however, than pulling a motor and having to redial the fan and clutch prematurely. It's the cross those of us who live in high humidity environments must bear to keep bearings going for a season.

A very good solution was put forward by a chap called MIkerobe who has to fly in high humidity areas and he placed a nipple at the front of his engine housing, this ensured that the oil had to pass through the bearing before anywhere else ensuring it was covered in oil. If you place it on the backplate you Will have to invert the engine for a while whilst the oil gets to the bearing.
Have a look at the pictures in his gallery and checkout a few of his threads on the subject. I don't think he will mind me posting this link, its very interesting

Busher, I believe it may have been you who refered me to that gallery in the past. I pm'd Mikerobe and he shared the details with me. His was an OS61 and 70. As bad as I wanted to, the 50, didn't have the flat step in the engine case and I just didn't feel comforatble drilling there.(although I think it can be done).

Dr Ben, the procedure you described is exactly how i pictured doing it. thanks for the reassurance that this could work.

Just had a look at mine and your right it is a bit tight on that flat, its not as pronounced as the 60 size, I agree its a bit of a tight spot.
My OS 50 is in a heli and the back plate area is not really accessable, but if you have a spare crankcase in your hands have a look at this for a possibility.
Use one of the backplate retention screws, can a hole be drilled through the threads into the crankcase housing. Then screw the nipple onto the backplate to hold the backplate in position. This method was used on a few engines to tap off the crankcase pressure in racing engines. It may mean getting hold of a new nipple or a specially made one but if the holes line up it will be an easy winner.

Swoop, Sorry I didn't check that out in my earlier post, But I didn't have a hyper at hand. I thought it made interesting reading though, and a good solution to a problem.

Good luck

Spent this weekend scavenging parts from two burnt hypers (plus one new ring, 2 new bearings) to build one good one. Added the nipple in the backplate as well. Got thru most of the breakin today and hope to find the final tune this week. so far so good. Now I'm experimenting with an old case to see how much afterrun is needed to properly coat the rear bearing. I'll keep close track of the flights on this one with hopes of it outliving my previous hypers.

I've use the Evolution Rust Inhibitor on my OS 50 engine for around 2yrs with no bearing problems. I inject it through the carb fuel tube and turn the engine over for full coating. You will have to do this every 4 - 6 weeks since it is very light and will evaporate.

It has worked great for me on the OS 50 engine, Do not use on the YS pumped engines as it will damaged the check valve and your engine will suddendly cut out.

Hope this helps.

I've been using Corrosion-X spray for about 4 years now with Zero bearing problems and my heli's sit alot over the winter.Simple procedure end of day remove glow plug after cool down rig a piece of fuel line from the plastic spray nozzle pipe to your carb fuel nipple or directly into throat of carb move carb to wide open and spray Corrision-X while spinning engine with electric starter within a couple seconds you will see a fog comming out the glow plug hole and stop.Replace glow plug hand tight and store heli at the next flying session remove glow plug and give the engine a quick spin to clear the oil and replace the plug and fly.Sounds like alot of work but it really pretty quick procedure and it sure beats taking the motor out for bearing replacement.Yogi

Hey guys, I was always told that the petroleum oils will eat the oring in the carb if injected through the fuel nipple. This is why I went through the trouble installing the backplate nipple. Plus can't get to carb opening on the Raptor. Any problems so far with orings?
