After several weeks of very windy conditions, it was finally nice enough to get some flight time in. I took the Tower Hobbies Kaos 40 out powered by my nice Enya SS40BB. I think this engine is just now getting broken in. This engine provides more than enough power to fly this airplane quite well through the pattern maneuvers. Unfortunately Justus wasn't able to keep up and catch any of them. Anything more than a hot 45 2 stroke on this airplane is really a waste of power and just extra weight.

The video clips are quite short but my video man Justus has been out of practice for a while, plus the Kaos is a fast airplane to try to capture. Some aren't too bad though.

I have acquired OS FS-20 and FS-26 Surpass engines. My flying interests are changing to something a bit smaller and more easily transported. With a connection to plans from yesteryear and a connection to laser cut parts I can enjoy some of the smaller airplanes from years gone by. Since one of my passions is 4 stroke engines, what's better than the now extinct OS 20 size engines?

I was comparing these two engines last night and this morning and noticed one significant difference between the two. Initially I had thought that they were nearly identical with the exception of displacement. Can you see the difference? No I'm not referring to the muffler either....

Don't cheat. The last photo obviously gives away which engine is which, but do you see the major external physical difference?

Well no surprise here. The engine fires right up and runs well. Typical Enya quality. This will definitely find its way into my new Tower Kaos 40.

I just received an awesome Enya engine, the Model 6101 40X TV. This is the oldest designed engine that I have owned. Most of my 'old' engines are from the 1980's, but this was reviewed in the June 1978 issue of Model Airplane News. I am psyched to run this engine!

My only other Enya 2 stroke is a SS40BB, but I am unsure when it was released but I love it! The SS45 was reviewed in 1987 which is the closest I can find to the SS40BB.

My SS40BB features a cast iron piston and a two piece crankcase, but this 40X has a Dykes ring and a single piece crankcase much like the OS SF series engines. I have never had an engine with a Dykes ring before but from what I have read they are excellent and oftentimes do not feel like they have any compression at all, which is normal. I was expecting this 'lack of compression' feeling, but was surprised. Once the glow plug was installed this engine had enough compression to make it quite difficult to turn over without a prop!

Again this engine has a typically beautiful casting and finish that Enya engines are known for. I am a bit torn as to whether or not to actually run it..... No, yeah, I'm going to run it!!! From what I have read the break-in period is considerably longer and more particular than a typical ABC construction 2 stroke engine. I will NOT be rushing this break-in.

Now for some pictures.

So in yet another trade, I find myself in possession of an older OS 70 Surpass engine. I bought one of these new in the early 1990's and it was a fine running engine. Then a few years ago I bought a NIB one here for nostalgia reasons alone, and then traded it off. So now I have another.

You may ask why I shoot Box to the Bench videos. Typically with used engines I purchase I open them up, inspect and clean them before I attempt to run them. The last few engines I have received I decided to change that up a bit. If the engine feels like it has decent compression and no external damage I will take the chance of running it.

This engine arrived in what I would consider good condition. It clearly had been used but it is unknown exactly how old the engine really is or how much run time it has. The fellow I got it from received it on an airplane so the history is unknown.

As you can see from the video the engine starts easily and runs quite well. I plan on cleaning the exterior a bit and taking a peek inside just to see what it looks like. At the conclusion of the last run the exhaust nipple came off the muffler so that is going to have to be fixed with a bit of JB Weld.

I made a trade with a great RCG member here, BWH. I traded my Saito FA-30S for his OS FS-20. These engines don't come around very often and it looked like a pretty nice, good condition engine.

It arrived today and I created my second Box to the Bench video on this engine. I took some pictures of the engine when I opened the box. Rotated the throttle arm to the upright position, and ensured the glow plug lit up. Aside from that I did nothing to the engine prior to running it for the first time.

As you will see in the video, it ran out of the box. I adjusted it to a peak running setting for the video. The airbleed carb needed adjustment to idle in my high humidity environment. I think the engine is a keeper!

I just got back from the flying field and I completed the first 3 flights on the Kaos 40. I can sum it up in three words, boring, excellent flyer.

What, wait? BORING? Yes, I said boring. You know the nerves you get prior to a maiden flight? Well I had those and they lasted about 5 seconds after it broke ground. The Kaos wanted to dive to the left immediately, but once I compensated, gained some altitude, I had it trimmed out in one circuit of the field. Here is where the boring starts. Once trimmed this airplane flies beautifully! There are no surprises at all. Being a precise pattern airplane it has NO self recovery tendencies at all. It goes precisely where you point it, PERIOD.

You hear the phrase "it flies like it is on rails", well it does. It is smooth, precise, and graceful. It makes an average flier like me look pretty good. HUGE graceful loops, Split S, Immelmann, and stall turns are a breeze. It does one heck of a snap roll too. All of this done on the maiden. I usually don't wring a new airplane out until the 3rd or 4th flight, but this plane, once trimmed, puts you at ease immediately.

Landings are fun. I bring it in on a long slow flat approach managing the throttle to maintain altitude and then chop it for a full stall 3 point landing. Quite fun!

This is not a trainer but anyone who flies their airplane and not the other way around will have no issues mastering this plane.

Unfortunately I have no flight videos as my cameraman is in school today. My Kaos is powered by my nice Enya SS40BB. This engine provides PLENTY of power for this plane. It is quite fast and there is no need, in my opinion, for more power. Now I do have about 5 other engines that I would like to try on this airplane but I am extremely satisfied with the performance the Enya provides.

when you are trying to trace out some parts? My girl Chloe thought she would help hold my plan sheet flat for me. Thanks Chloe!
