Nitro engine storage habits ?
Just curious to after run engine Maintance rituals anyone can share for nitro motors .. I've never used Wd/40 or after run oil and I've always have had them last and fire Everytime. Then I hear of story's of just a few months of sitting and engine is toast , bearing done ..I know nitro is corrosive but just a few months. I know the higher the nitro the more corrosive.However Iam in a low humidity climate as well .. Just curious for some to share experiences good and bad
I don't crash, I land at full speed!

I do not use after run oil from day to day flying, but I do if engine will be stored for an extended period of time. (Month +) I always empty fuel and crank engine with glow ignitor on after every flying session to burn out any fuel in motor. The odd thing is I use after run oil after Every flying session in my glow planes. I believe this is simply due to the fact that the engine and glow plug are easier to access.

I only used after run oil ( Marvel mystical oil) when I used fuel that did not contain caster oil . And when the engine was going to sit all winter then I would oil them all . And also like what was said , run all the fuel out of the tank and keep starting the engine till it won't fire any more , get all the alcohol out of that engine at the end of each day you fly ! I have engines ( airplane ) 25 yrs old that still have good bearings ! Good luck

I do this as well.

Never use after run oil. And in the Spring after sitting all Winter in the house, sometimes the rear bearing is OK, sometimes it is not. But bearings are cheap and super easy to replace, so I dont stress over it.

I don't do anything. Bear in mind I keep my helicopter inside and it rarely goes a month without being flown. That being said I did a bearing/ring/hone job a few months ago on my OS 55 because it had been close to 3 years since it's last service. Bearing still looked perfect but I was noticing the idle was getting a bit gravely. After servicing it is good again.

Am noticing the same symptoms on my trusty Redline 53 and just ordered a ring and bearings. I have always cared for this engine in the manner I described and bearings feel fine. It has approx 12 gal of fuel through it now so I just figured I am long overdue.

I've tried most methods over the years and still don't have a stand out favorite. After every flight I run the fuel out of it until it won't fire. If it's going to sit for an extended period of time I try to add after run oil. Marvey mystery oil will actually burn in a nitro engine so I've actually fogged them with oil like you would a regular engine. Now I tend to just flood them with oil in the fall. In the spring I tip it so the exhaust side is pointing down and turn it over by hand to drain the oil. Once I can turn it over freely I crank it over with the starter for a few seconds. Then I open the fuel line and fire it up. My thoughts are that there are no negatives to running the appropriate after run oil for storage. The main issue for me is access in a heli. They should just add a nipple on the back of the crank cover for adding storage oil.

However Iam in a low humidity climate as well

that is the key, I have gone through bearings in a month and have tried all the precautions, plugging up exhaust, running the engine dry, then turning it over with glo attached to get last bits out,used after run oil,
I then turn the engine over so it closes the exhaust port..

I still manage to get rusty bearings, but I fly very infrequently and even though I keep my nitro indoors there is still humidity..

the secret I guess is to fly frequently

I got tired of the rusty bearing problem and finally went with the Glide bearing installed by Buzz at Magnum fuels. Now I don't have to worry about rusty bearings.

I just leave mine full of fuel...tried all sorts nothing stops the rust and the engines like having fuel inside them....

I almost forgot that I always plug my exhausts also with a wadded up paper towel after every flying session as well- thank you MattJen

I make sure that I never run one dry at the end of the day (really bad for glow engines).

I shut them down by closing the throttle, pinch off the fuel line, fill the tank to evacuate the fumes which will rot your fuel lines and corrode things), drain the tank again, clean the ship up and put it in a canvas bag.

No bearing issue-period.

+1. I also fill the tank and then plug the muffler pressure line. Keeps the combustion products which contain the nitric acids out of stuff. It seems the corrosion goes down remarkably.

Have not seen any increase in bearing life on account of using after run oil. However, using quality fuel has made a difference. You get what you pay for in a fuel's oil package.

Only time I might use after run oil is if I KNOW it's the last flight of the year. But we have good days even in winter, so there's no "season" to speak of.

I also run a fuel magnet so my tank is always completly full unless the heli is actually flying.

Actually, running your glow engine dry at the end of the day is a good thing. You won't damage your engine at all. Just disconnect the fuel line from the engine and start it up. When it quits, start it again. Do this until the engine won't fire. Add after-run oil and put it up until the next flying session.

Yeah people worried about lean runs. It's not running lean long enough to hurt anything. And unless you are running full power followed by an autorotation at flameout, it doesn't really have any potential to heat up. +1 to bbaxter I've been doing that for over a decade (although I use a clip on the line) and no damage from it. It seems to inhibit rust.

The issue is methanol is hydrophilic, meaning moisture loving. So water gets in it and rusts stuff if left in there.

Keeping moisture out of the bearing between flying sessions; after flying I remove the bottom plate and flush out the brg. With fuel..then I put a few drops of mineral oil on the brg. and turn it with my finger to get all the balls coated..mineral oil is non-conductive; if you do a search on "electrolysis and brg. Failures" you will see it's a known phenomenon; anyway I sit my heli on top of a "remington de-humidifier" with the backplate removed..keeps it dry; it really works..been running the same stainless brg. In my 91hz for a year and a half now.
I do a great decending funnel!

Fwiw,
I live in the Bahamas...very humid and very salty where I am. The worst environment where nitro is concerned! Using Byrons RotorRage has helped significantly with corrosion/rusting on the internals.

I've recently experimented with running my motors on my weedeater's fuel mix after flights. This is comprised of Camping fuel with a 40:1 ratio of Evinrude's XD100 full synthetic outboard oil and has proven very stable and an excellent lubrication package.
I used a syringe with 4" of fuel line attached, drew up some fuel and connected this to my carb. I then connected the glo driver and with a few small movements of the syringe she was running on the camp fuel. After a few minutes of running, I then ran her dry of the camp fuel by cranking with the glo driver attached.
This is the first time I've done this but I'm sure by running the motor on a petroleum based fuel...it has displaced everything nitro. I don't think the O-rings will be affected by such a short term exposure to the camp fuel.
The other obvious thing I noticed was the significantly higher motor temperature when running on the camp fuel.
Obviously time will tell when I pull them out for flying again!
The lot I got is not a lot, but I thank God a lot for the lot I got!

I store everything inside the house. I use Wildcat fuels exclusively and I do nothing for after run since the mid 1990's.
