Fins. Fat fingers

Head is 90 degrees off! Find should be fore & aft, run cooler

Are you sure they are phillips scews ,? I think it's Jis screws when you say they get stripped out.

I don't know how much flying you've done, but this is exactly what my friend did (who is a full scale pilot) on his first RC flight with no experience or training.

would have been more enjoyable at regular speed

Did you not forget the exhaust baffel ?

Nice job. Not having an ultrasonic cleaner, I have soaked in old antifreeze in an old crock pot for a week or so. Heated is good. Lately I just dunk the whole engine in Dawn Ultra for a week or so. On an engine like this (no ball bearings), once free, you can just mount it and run it for a while. I use a covering heat gun for heating up the parts, as at 220-degrees, it can’t get so hot as to damage parts. Also for drying out ball bearings before loading them with oil. One caution on the antifreeze, it is flammable. Also, you do not want to use that old crock pot for food any more!

Excellent restoration video. However the so-called crossflow engines (ridge on piston) are not in the same league as the SS (Schnuerle scavenge) Enya engines that came later. Having tried to fly a crossflow engine It seems that, in pursuit of power, they ended up using fairly extreme port timing with the result that if they drop out of their power band it can be a devil of a job to get them back in. Not ideal for rc. The SS engines give a lot more power and throttle much better.

Engine rebuild? NO!

Mate tune that engine, please.

The music just sucks! Cannot watch

A better lube for these motors is Rislone Motor Treatment....

How would this go as a car motor🤔

My little enya 09 ran well ,.still got it 🥹

The Easy Fly 40 was my first rc airplane and I learned to fly rc with it. Mine had an Enya 40. I just rebuilt my Hangar 9 Advance 40 that I have had for 20 years and can’t wait to fly it again when the weather permits.

why skip removing the bearings?

Yo, thanks for the help , this video showing the connecting rod and piston rod removal helped a lot , on a side note, 11:38 to 14:30 is when the wife came in and asked what I was watching … 😳 brown chicken brown cow …

Nice rebuild, thanks for sharing. I used to use Enya's back in the seventies and found them difficult on initial start up from new but great when run-in. Later moved on to the larger Fox engines which I am thinking of pulling out to display in a cabinet so this video will be helpful.

Would have been more helpful if you illustrated how the cleaning of the old engine was.......... done*

Bitte keine Zangen !! für die Schrauben und Muttern. Dafür gibt es Steck- und Maulschlüssel .

Don't see the "next video" of it running on your chanel.... ???

WHy did you speed up the video ?

I'd be more interested in what you used to clean the parts with.

I see this video is 4 years old but my engine has very similar markings 14:35, so I thought it was worth commenting. On mine the 'dremmel mark' has been caused by a metal fuel bung at the end of the filler hose, rubbing during flight. It's not a good idea as metal clanking as it can cause radio issues. It now has a plastic bung.

How do I connect fuel tank to this engine

I was given a 40 SR. Is it as good as this SF?

I have one now old school os .40 4 stroke

Wing span...? Fuselage length ???

cool vid. everyone i tend to watching a train vid, its crashing into something

I love the flying space. I don't see any hangers but it looks like a runway for full scale. That's been kind of a dream for me; having a house with that much land to be able to fly without loading up the planes and the gear and driving an hour each way.

Hello I was watching your video wondering if you know where I can find a thrust washer bearing for A OS Max 40SF ring Nitro. Thanks peter

That has to be the one of the worsed strip down I've seen mate just dumping screws, useing multi grips to pull off carb, wow, if you are stripping down at least use a small containers to put in small parts??

I still fly airtronics fm

Dogs again ! Dogs rule !

Looks like he found something stinky to roll in my beagle used to do that

I love dogs

40yrs ago my first engine into a line control plane was an ENYA diesel

Gr8 vid mate. Wot did U use to clean the parts cheers

Hello How did ya clean it so well?? I mean did you use some chemicals or?? I have an engine in similar condition O.S size 40. Plzz help

?

I had a 2003 convertible and I sold it at 90,000 miles. Sludge was not an issue but I also had frequent synthetic oil changes. I know that PCV valve fix existed but I never bothered.

Model Diesel Engine Starter Mk.2 Uses a clockwork type spring to wind up and start a Model Diesel Engine Model Diesel Engine Starter Mk.2. A tester is wanted, (UK please), (not Glow Plugs) to test with some real Model Diesel Engines and provide feedback. I am looking for a KZbin Real Model Diesel Engine Starter tester as I do not have the budget to buy one for testing. Contact me on KZbin if you have a KZbin channel to video a real life test using a Model Diesel Engine. This has mainly been made using a 3D 3D printer..

like your flying area,where about are your flying.which part of the world.nice flying too.thanks

My second plane back in the 80's flew great with 15

This is great

I too am disappointed in the lack of survivors to be eaten.

It definitely is a nice flying plane the Sig Lt40. I'm thinking about getting one for a brand new OS 52 fourstroke I have still in its box. Have been looking for the right plane for that engine and I think this plane the more I see it flying is the right choice. Great video, I enjoyed watching it.

Very nice video and everything explained well. The plane flew great and touched down nicely. Thanks for sharing, I enjoyed watching this.

Hi there, nice video and plane. How do you think this plane would do powered by an OS 52 fourstroke?
