I'm a sucker for Enya 4C engines and when I found a listing on RCU for an 80-4C I watched it carefully. For a few days I watched and pondered,; the asking price was a bit high for what it was. After about 3-4 days I submitted an offer for $30 less than asking price. Well, it was accepted. There was only 1 picture to look at in the ad so it was a bit of a gamble.

I should have known better, as I have owned enough Enya engines, they are pretty indestructible. It arrived a few days ago and I took some pictures of it. Unfortunately I am at work entering this post and I do not have the pictures on hand, but I will post them tonight.

It was pretty dirty on the outside and was quite hard to turn over. The carb had some damage and dings. it was also pretty badly tarnished. I completely tore the engine down and was happy to see that the top of the piston was not dark at all. After removing the exhaust valve I found that this was a fairly low time engine as there was no significant deposits on the shaft. The piston ring was free and rotated easily with little to no deposits in the ring groove.

Aside from the carb damage and a ding to the intake manifold it looked pretty decent. I ordered a set of crankshaft bearings but after cleaning the residue off the rear bearing I decided to just re-install them and see how it runs. It runs pretty darn nice as the video shows. This is an engine I will be keeping for myself.

The OS 25F ABC engine was released to the market in 1982 and a review can be read here.

I bought this engine from Ebay about 1 week ago. It was advertised as "bench run only for break-in purposes". Nothing more than that. When it arrived it would not turn over at all. The exterior was excellent and did look to be a very low time engine.

As standard I took it apart to determine the condition of the inside and free it up. The top of the piston had no carbon build up at all on it confirming the low run time. There was little evidence of running inside, no excessive residue or rust, It looked quite nice. The one or two runs it had were just enough to, over time, freeze the parts in place.

Once freed up the engine turned over smoothly and the bearings felt nice. I lubed it up and decided to give it a run.

As typical with OS engines of this era, it is a fantastic running engine. Hand starts are easy and was tuned transition from idle to WOT is quite nice. Take a look.

Well this engine turned out just like I thought it would, another nice running OS engine from the 80's. Not much more to say about it other than that. The video pretty much speaks for itself.

The bearings arrived today and I was all excited about getting this engine back together. I will be running the engine again tomorrow. I think this will be a keeper.

I shot a video of this engine running today. While running I found that the bearings need to be replaced. At this time it is completely torn down and waiting a new set from RCBearing.

So I was browsing Ebay last week and saw an auction for this little engine. When I saw it the auction time was down to the last hour. There was only one bid so on a whim I bid $1 higher figuring I would quickly be outbid. Well that isn't how it happened. As the time wound down, no one was bidding on it... uh oh. I just bought an engine I was really only curious about.

Anyway it is here and it is a fine example of 1986 OS engineering. This was the early days of the Surpass series of engines. I have taken pictures of it next to my 48 Surpass, which followed in 1987. You can tell many differences in the exteriors of these engines.

I have not run this engine yet, but I did take a look inside. I plan on running it tomorrow. BTW, it is for sale too.

So in my browsing of EBAY, I stumbled across a really decent looking OS 40FP on a Buy Now or Best Offer type of sale. The buy it now price was $65, NOT! So I made an offer well below that and it was accepted! I took a chance hoping it was a low time engine based solely on the pictures. It would not turn over was the only other description.

Well it arrived today looking just as good as the pictures. Sure enough it was locked up tight! I removed the muffler and quickly discovered why, rust! Yes sir! This is an early cast iron piston OS 40 FP!! It had surface rust on the piston keeping it from turning over, that was it. I took it apart and soaked all of the iron/steel parts in CLR and viola! Brand new engine!

the way it looked inside the back plate I really do not think it was EVER run. Not one sign of dried fuel, oil residue at all. Check out the pictures. I even have a picture of the piston attached to a magnet. These are quite rare to find especially basically new like this one. It could be for sale.... make some offers....Continue Reading

I recently acquired a very nice vintage Saito FA-45 MK ? ABC engine from a great member here on RCG. I said MK? because this is the early two piece head version of the FA-45. The box does not have a stamp in the white circle on the box used to indicate the version, but the instructions state that they are for a FA-45 MKII ABC. This is where the history and timeline of Saito engines becomes quite blurred.

In either case this is an excellent example of Saito history and a fine specimen. I have s few pictures of it sitting next to my other FA-45 MKII. However there are several the big differences between these engines. The boxes look to be about the same time frame but the engines could not be more different.

1. Head design.

2. Intake manifold due to head design.

3. Rocker covers.

These are the major differences, but there is another that is a bit more critical, parts availability. The single piece head shares many of the same parts as the modern Saito engines. The two piece head has very different rockers arms making them nearly impossible to find if necessary.

Yes during the Christmas break I scored yet another Enya 60-4C engine. This one was a bit worse than the last one. This one did not have a carb or exhaust header and looked 10 times worse!

Visually this looked like a mistake right when I took it out of the box. But I set to work inspecting it, and then doing some preliminary cleaning. Again all the fasteners had crud in them so that all had to be cleaned out before I could begin dis-assembly. This thing looked like it had spend time at the bottom of a lake and unfortunately I was not able to get the exterior nice and shiny again.

What a surprise once I opened it up. It looked like I scored another low time engine. I did shoot videos of the dis-assembly but took very few, i.e. none, pictures during the process. I got so wrapped up in the process that I neglected to take any pictures except the before and after ones shown here.

Rest assured the piston looked new and although the ring was compressed and stuck in the ring groove, once freed up sealed quite well. Even the valves showed minimal run time, with no real carbon build up on the exhaust valve at all. My estimate that this engine had less than 1 gallon through it. I will be running it tomorrow and shooting video of that.

The parts I had to replaced/include in this rebuild are, a new carb, new Enya #3 glow plug, and exhaust header with nut. All other parts were in good enough shape to re-use.

It may not look the nicest on the outside in person...Continue Reading

The bearings arrived today and I am still editing the final re-assembly videos as I type this. I went ahead and posted the video of it running.

I have added some pictures comparing my 45S to this one. I see why the new one needs that spacer for the carb, mine has a bit longer carb mount on the back plate. That could indicate that the one I just refurbished could be an older or more original 45S.

I took a chance on something I had done many years ago and got burned on, I rejoined EBAY and setup a Paypal account. This could have proven to be a mistake.....

So I was exploring EBAY looking for some deals to exercise my new account. I found what looked to be a decent deal on a very worn, heavily used looking Saito FA-45S. The 45 Special edition is a seldom seen version of the 45 engine. I was lucky enough to buy one NIB many years ago and it has served me very well. Now I had to have this one too. I bought it primarily as a project to refurbish and potentially resell.

It arrived on the mail yesterday, not in a box, but in a padded envelope. This was an immediate concern. Luckily for me the engine was undamaged but I cannot understand why someone would mail an engine in a padded envelope. This was purchased as shown below in the first few pictures; these are directly from the EBAY ad.

This engine has the look of one that was heavily run and then just placed on this display stand with absolutely NOTHING done to it. I can only imagine that the person that did this wanted to capture the engine and it's dirt and grime as it was from its last flight. That is all well and good, but I have no intention of it staying that way.

As usual, I documented it as it arrived to me and I shot some videos of the cleaning and dis-assembly. As it stands now it is torn down completely awaiting the bearings from RCBearing to arrive. They should be here tomorrow and then...Continue Reading

First run of this engine after dis-assembly, cleaning, and reassembly.

Enya 60-4C First run after reassembly (5 min 27 sec)

Posted by dmrcflyr2 | Dec 15, 2015 @ 07:44 PM | 2,300 Views
I recently purchased this used Enya 60-4C right here on RCG. The exterior looked pretty dirty and little was known about the engine. Instead of doing a Box to the Bench video I decided an internal inspection and cleaning should be done first. I did not want to risk damaging the engine by running it first.

As it turns out it looks to be a very low time engine. The exterior was just dirt, dust, grime mainly.

Here are the first 4 videos detailing the cleaning, disassembling, and inspection of the engine. More videos will follow in this playlist as the reassembly takes place.

I have added some before and after photos.

I decided to make my rebuilt old school Saito 50 a permanent open rocker engine. I looks pretty cool and runs just as well as before, obviously.

Here is the video of it running. I love watching those rockers move.

Yesterday I reported that I had received 2 engines, one of them being a well used Enya 19X. I completely disassembled, cleaned, and reassembled this engine. Luckily the bearings on this engine still felt pretty good. Obviously they have been changed before. The internals showed considerable run time and it had very low compression.

The parts cleaned up really well and I just ran it for the first time, much to the dismay of my neighbors.

Today I received 2 engines in the mail. One I bought and the other Balsaworkbench(Rob) bought on Ebay and had sent straight to me.

First, my engine, A very nice OS FS-48 Surpass. I purchased this engine here on RCG and thought it was a used engine, but upon arrival, I was not sure. I wanted to do a "Box to the Bench" review on it but since I could not tell that it had ever been run, I decided to open it up first for an inspection. I then ran it several times after the initial inspection. As it turns out it isn't quite as pristine as I thought. The high speed needle is bent causing some inconsistency during running and one of the pushrod tubes is dented. Overall it is an extremely nice engine and one I will keep.

The second engine is an Enya 19X. This is a very well used engine and had very little compression. I completely tore this engine down, cleaned up the parts and re-assembled it. It now has very good compression and should run quite well. I still need to clean the carburetor and get it freed up before I can run it.

A total of 4 videos were made covering these engines. They can be viewed on my YouTube channel.

I just received my latest vintage Enya from the other universe. A fellow no longer in the hobby. It is the Model 7101 60XF II Ring. The best I can find out this was released in the mid 70's. It is a very large, substantial engine. I have no current plans for this engine nor do I think I am going to rush into running it.

It felt a bit rough turning the crankshaft over and since this is a NIB engine, I knew it wasn't due to being run and just put away. It had to be the 30+ year old oil in it. So I decided to disassemble, inspect, and re-oil all moving parts.

I used the heat gun and some 3 in 1 oil to loosen up the bearings in the front housing. After that I sprayed them down with alcohol and then blew it dry with compressed air. I liberally oiled the bearings again. No they felt smoother than before. Once I do find an airplane for this engine I might just replace the bearings and start fresh. For now all internals have been wiped clean and oiled up again for storage....Continue Reading

For my nice new Enya SS25BB. What a nice looking engine. Aside from the instructions stating too lean of an initial needle valve setting, the engine starts easily and ran well for the first tank. I have two very rich tanks through it now. Here is the first.

I just scored another really nice Enya SS25BB from a great RCG member here cappy0161. Thank you Robert! This engine features a ringless cast iron piston in a steel sleeve. What that means is that this engine will last forever.

Here are the pictures.
