Well, my used OS FS-48 Surpass failed to run properly. It has an air leak.

I spent a while messing with it. I had even fitted a gorgeous Xoar 13x4 prop... so sad a nice 70F day and i could not get it running.

I am selling it, have other projects and could use some cash. Someone else could likely use it as a parts engine if not get it to work properly

I think it is a nice looking engine. But i sold it to help fund other projects

So i thought...

'Hmmmm... i do not remember adding oil to this used Saito FA-80. It should have more compression when fueled.'

Checked the valves, all is working. So i added oil down the rod tubes, on the rockers, & atop the piston. (I should also add oil through the breather nipple for preservation)

I cannot turn it over by hand via the drive washer! Huge compression! I do not want to assume this is one of those high-compression FA-80's. But i don't know much about them.
Funny thing, i imagine it will prefer an electric starter--unlike my other Saito 4-strokes. I won't know until i try (not to get my hand bit lol)

Why am i excited? Because this engine was sort of a gift & in questionable condition. And it's a Saito!
After discovering it in a box-o'-engines, i was hoping i could get it working. i do rather enjoy this brand

Initially i was unsure the FA-80 would have any compression, so this is good news! The bearings felt ok ...but who knows at this early stage of 'discovery'

Not a pretty Saito, well used. Outside is worn. Some minor things are buggered up, maybe the result of a crash. I don't mind, kinda cool.

I plan to run it with just the header pipe. Heck, I may even remove the rocker covers to salvage the gaskets for my prettier engines. Less weight
I have not yet adjusted valves. But when i get this old mill running it should have some real power!

Let's see... 13.1cc, 27mm bore, and 1.3hp. Has some heft but nothing to sneeze at. 12x9 to a 13x8 prop is recommended on saito-engines.info

Imagine what you could fly with a Saito .80

I planned to snag me a new Saito FA-120R3 in the first quarter of this year, but... i have other more important responsibilities. So it could take a few years

Yet... if i'm thoughtful, i could make it happen. The 120R3 is at the top of my list. A careful balance of size and power, it would be useful for me since it is small enough to fit the size planes i prefer.

Some multi-cylinder engines are quite a bit more displacement! I figure i don't really need much more than 1.30 size engines.

The greatest threat to my radial quest is... other engines. I plan to add a Saito .56 and FA-150B to my collection. An FA-62B would be really nice too

As far as multi-cylinders go, i want these most:
FA-120R3 (mentioned)
FA-100Ti (inline v-twin)
FA-100T (opposed twin)

I admire the Saito FG-57TS, OS IL-300 Dia-Star, Enya VT-240, Saito FA-200Ti, & OS FT-160. These are rather large engines for my taste, so i enjoy watching them from afar

I finally finished rebuilding my Saito FA-45 MKII glow aero engine

To clean it i used LA's Totally Awesome Cleaner. Then replaced the bearings & modified a carboard box to store it.

Originally the engine was in questionable shape, having its rear bearing only partially seated. It also had an extra spacer added to its [rear] case to compensate for the bearing.
So, i was unsure about this engine. But it grew on me as i worked on it. I was planning to sell it ...now i'd rather like to keep it.

This .45 sports a genuine Saito P-2 glow plug and will spin a Xoar 11x6 propeller (hopefully) around 8,800 rpm. (I am not sure about the rpm so i have to double check my info).
It is missing the Choke System but those are not necessary. I did find a metal mount for it and estimate runtime is over 4 gallons. It has strong compression

These specific .45's are not powerhouses. They have a milder cam profile compared the the FA-45S and FA-50. However, they are noted to be well-built, may last a lifetime, & can achieve a low idle (which tickles my fancy)

I had to make a Polypropelyne Cam Spacer after losing its OEM Teflon spacer. If the modified spacer does not handle the power/heat i will try to locate an OEM Teflon (paper-thin!) spacer.

A Special Thanks to Alphatex for the spacer idea!

I finally flew my repaired E-flite P47 'Jug' today. Stock with 2-blade prop.
Fun plane, but man! I am rusty. I have not flown anything significant in a while. Also have not flown the Jug since 2016 (wow)

So, I originally suspected my Spectrum DX6i malfunctioned when i crashed the Jug during Memorial Day 2016. Nope.

Rather, it was my fault! So i cannot blame Spectrum. The radio worked fine.

I see now why-- it looks like the Elevator was not trimmed properly causing the Jug to dive slightly when i let go of the sticks. What a n00b mistake i made

I remember that day:
I was tired from work. There was a hill on the left i somehow forgot about. Oh! I was flying low and fast toward the hill
I clearly remember the plane seemingly wanting to dive before i could pull up. I must have had the elevator near neutral before the wreck. This would cause the inadvertant dive--because the Elevator needed to be trimmed.

Lesson: Trim plane properly before performing low maneuvers.
Lesson: If you're tired be ready to crash.
Lesson: Note hills.

I will post the video--the actual crash was somehow missed but basically the plane pancaked in and tore the front cowl area off It was a clean break, ripping the motor leads from the ESC. There were addituonal tears in the wings but easy fixes.

All it cost me was a new 2200 LiPo and plastic Cowling. A bit of glue and tape and she was ready to fly.
Sure did take me a while too! I kept leaving things until recently. I bought a new tote for my gear and made a list on my phone. So now i won't leave important things like batteries or the radio...

My E-flite Jug is flying great now. Not a fast plane stock but quick enough to enjoy. She can come in nice with flaps and is capable of some interesting aerobatics.
The Jug is an easy warbird to fly... but you do have to keep some speed compared to a Cub or she will stall. Later i plan to make her faster.

What a fine little jewel!

I got a 'pre-owned' (never run) Saito FA-40A four stroke glow aero engine It was a Christmas present.

It had some rust on the crankshaft threads so i cleaned it off. A minor imperfection on one valve cover. No biggie. That is grease at the cam-cover, not a boo-boo.

The best part, it looks all new-y inside

I cannot believe how tiny & lightweight it is compared to my Saito FA-45 MKII!
It even has the Saito prop locking-nut and a 2-needle carb like my larger FA-72 and FA-91S. No idle stop screw but that is OK.

I am not a fan of the header on this engine. I rather prefer a pipe or the exhaust system style found on an Enya 46-4C

From what i have read, FA-40A makes higher rpm with an 11x6 prop than FA-45 MKII. It would take an FA-45S to match it.

To be fair, the FA-45 may have a lower idle ...and is an older, classic, vintage, rare, collector's piece run only on Sundays by a top-secret Spetznaz group located in New Mexico

Just need a new prop

Update: Here are some performance numbers posted by The Pipe circa 2016:

Temp 70F
Dew </= 60F
Fuel Wildcat 15 nitro 18 synth/cast blend

Master Airscrew GF-3 11x6
Max 10,350
Idle 2,200
4lb 7oz static thrust

Master Airscrew K-Series 12x4
Max 10,200
Idle 1,800-2,000
4lb 11oz static thrust

Not bad at all!

An FA-45 MKII will turn an 11x6 APC around 9,000 rpm if i remember correctly.

...tips on my preference of simple, effective, cheep engine cleaning. Here goes:

If your engine is very rusty, consider using a rust-remover and rinsing it off before cleaning. The LA's Totally Awesone Cleaner may remove tad bit of rust, but not much.

Set aside time to clean your engine. I prefer a day off work with 4-5 hours of free-time.
Point is, there's no need to be in a hurry! Accidents happen and parts get lost. Be careful with chemicals.

I do not have an ultrasonic cleaner. I use a plastic tub i bought at GoodWill for cheap...
My tub is at least large enough to cover a small disassembled engine (say, a Saito fa-56 size) with one bottle of LA's Totally Awesome Cleaner.

One may prefer a second bottle of cleaner for a medium engine (.91). Or just turn air-exposed parts over during soak. Depends on container size (skinny and tall will cover more).

Really, you can use the tub of cleaner on more than one engine! The cleaner will get darker but it should work.

Items needed:
-New bearings. Why not?
-Gaskets and O-rings (if needed)
-Valve adjustment tools
-screw drivers and hex drivers
-Always have extra bottles of cleaner, $1 at Dollar Tree
- Q-Tips or pipe cleaners for carb and intake drying
-Clean light-colored towel for lying parts upon. Nothing fancy.
-Old clean rag or two for drying parts.
-Paper towels, can be cheap
-Tweezers or something to grab parts out of tub
- 3-in-1 oil (or your preference) to remove bearings & stuck parts....Continue Reading

For a good hamburger try:

-Ground Beef (70/30) or Ground Chuck (80/20).
-Start with a 2.2 oz. puck of beef and smash into 6-inch circle. Or something like that.
-Use Lawry's Seasoned Salt.
-Consider butter on bun and cheese.

This may produce a burger similar to Steak 'n Shake. I hope. (I have yet to try it)

Firstly, I think Saito should sell an 'FA-112V' V-twin (based on the .56B). Or at least bring back that wonderful FA-100T opposed twin. With pipes, no mufflers

I think Saito could sell certain engines as kits on a made-to-order basis:
-The FA-56B, the FA-82B, and the FA-115.
-Bring back the FA-91S as a 'Classic Kit' engine.
-I would enjoy the beautiful FA-150B as a kit! But i do not know if it would be profitable in this form.

-Included tools: Gap Tool and Valve Adjustment Wrench only. Glow Plugs sold separately.

Knock off about 1/9th price for kit engines with a limited warranty for parts.
Include disclaimer explaining that these are kit engines and performance relies on the assembler

This would be experimental for Saito. I think the kit engine market is more a niche, atm, for Saito. But has potential...
The FA-56B may be a good engine to test such a market. It is popular but also has been discontinued for sale in America according to the Horizon Hobby website. It is a respected engine with enough power for certain small balsa model airplanes. Sounds nice too!

Saito could attract non-modelers to this 'kit engine' market! There are 'mechanical' people out there that would be interested in this. This may ultimately lead to more sales in the model engine market as non-modelers discover RC Model Airplanes.

Saito could use YouTube for advertising their kit engines. Short and sweet.

You don't even need nitro in your methanol/oil fuel to run Saito engines. But a little nitro may make tuning easier

Did you know that Corsairs had six .50 machine guns or four 20mm guns? Want to sit back in your comfy bed, eat popcorn, and learn about the PBY Catalina? Do you like F4F Wildcats or giant flying boats? Jets? Have you heard about the NASA X-Planes?

You gotta check out this playlist on YouTube. It's great! A lot of the video is older... but you will learn about some crazy awesome stuff. Totally worth it

The playlist is a bit difficult to find, so remember what it's called if you decide to type it in the YouTube search bar. It is the playlist with 98 videos**

Remember, it is a playlist and these videos are actually from several YouTube channels all collected into one list. However, you may simply press play for hours of entertainment

**(It does look like some of the videos are being deleted, likely by YouTube copyright or Channel deletions... so watch them while you can)

Grab a drink & take a load off...

Not mine. Must be an early version... Also noticed a nice clean older FA-40 on the 'bay.

Tuning is easy. I am too tired today to try the tachometer again... busy job day

It is nice to have a place to chat (er, post) with other fellows who understand model aero engine collecting.

I have slowed down recently.
I hope to get back to 'restoring' a handful of my used engines. I can take my time, no real hurry

I have a few on my radar. If i didn't have to buy dumb things like shoes and food...

If anyone's Cub is 'dropping out the sky' they may want to play with the CofG.
I remember using a 1300mah stock lipo and fiddling with the CofG in zero wind. The Cub would float like a feather. It was dreamlike

Many of these RTF planes are set up to be a tad nose heavy for n00bs--the manual often states to set the battery a bit forward. Often setting the battery back +/-1 inch results in proper flight. Ymmv

I have even heard the horizontal feathers to be set improperly [on different RTF models] to better aid n00bs. But i cannot say for certain or which models ...besides the initial release of the UMX P47. Maybe it was a fluke, dunno

I may remove my VG's to promote sportier flying. This may require filling the void.

The VG Void... hehe

Also, am thinking of adding more area to the Rudder.
I like lots of Rudder Authority. Useful for getting out of gravity incidents. I noticed this while nearly piling my aerobatic & 3D foamies.
Numerous times, Rudder has saved my wallet.

This model Cub is fine stock.
But it is a nice 'test subject' for experimentation. Mine is a bit discolored and bit up from Kittynado. So if i pile it, not end of the world.

The world may Pile
I resist
that nincompoopishness

Lol... so I finally got around to mounting my Saito FA-72A for some testing.

I mounted it to a sawhorse, which was already occupied with my FA-50 mount on its opposite end

A special thanks to my brother-in-law for helping me cut the cheese ...er wood... with his saw.
I used 'Whitewood' (3/4" inch thick by about 9" long). Whitewood is a bit soft (hey it was cheap). I recommend tougher wood, like Oak or Plywood.
But it looks like it'll work for now.

I just eye'd the wood work for the .72. It was easy.

I used 6-32 x1&1/2 screws, washers, and nyloc nuts for the Whitewood engine mountage.
And used larger 1/4 x20 x2 screws to mount it all on the Genuine Burro Brand sawhorse. I wish the 1/4 screws were a tad longer for bolt usage. But it should be OK for now.

I recommend bolting the screws with washers and nyloc nuts when possible.
Also, be sure and check the assembly often. Easy to lose fingers...

I plan to add more foam under the fuel tank.
I need to check .72 valve clearances. Should be rtr soon

It was dusty/nasty after sitting in my friend's garage. It is not assembled.

It looks much nicer after wiping it down

I would rather it be a tail dragger. I may add a skid in the rear

I got a new idea for a 3D airplane design: 'rotor' placed in right or left wing. Or both...

So when hovering, can use rotor in favor of, or in addition to, Aileron control.
Kind of like a helicopter.

This should aid in controlling torque roll. I call it: ROFLcopter

I will post a crappy pic soon

So i had a few awesome RC Cars/Trucks back in the day...

1) Team Associated Nitro RC10GT Plus RTR (Stadium Truck)
I kept snapping the diff gear 'axle' otherwise simple truck with a nice reliable Thunder Tiger .15 glow engine. Because of this issue, i gifted to a friend. I wish it had a gear diff..

The Thunder Tiger .15 was my most reliable 2-stroke rc car engine. Not a screamer, maybe 30k, but one of my favorite engines. I liked the way it looked too.

2) Traxxas T-Maxx 2.5 RTR
This was a beast. Nitro 4wd, mechanical reverse, 35+ mph, 8 shocks.

I jumped a ramp and performed a controlled flip, landing on all four tires.
It had large tires with tractor style treads that had good grip.
You could add throttle or brake mid-air to control pitch like a dirt bike!
The tires would last a loooong time too. But who wants to rebuild 8 shocks?!

Fidgety engine... Traxxas claimed 40,000 rpm on the 2.5 but i was always twiddling with it. If i ever got 40k, and i bet i did, it was overheating...

I let a friend borrow it who kept it outside. My fault, i was supposed to retrieve it. It got rained on and forgotten. Not a big deal, i had a blast with that crazy truck.

3) Team Associated Nitro TC3 Team Kit
I built this kit with a beautiful OS .18 CVR-XS that would light up all four tires on demand.
My friend said he thought it was hitting 65mph. 2-speed with some blue ano'd aluminum parts.
I think it was at least 60mph. I painted a nice 2004 Subaru Impreza rally body...Continue Reading

... been working on a project

Saito FA-72A with the pipe that Gary made me
The Ultimate fidget spinner.

It is destined to go in a used Easy Sport ARF that i have yet to assemble.

This is actually my 2nd .72. It looked RTR as i recieved it.

Hopefully i will mount/run it soon.
I want to hear it!

Here is a pic of my low-time K&B Sportster .28.
It looks to have been bench run only.

I saw a friend run one and liked it; the sound and muffler is nice for a 2-stroke.

It came with instructions, an e-mail letter, & some notes including the test run data. This shows its history, which is sweet.

I heard some modelers had trouble with air-sealing one of the larger model K&B engines ...dunno if it was a fluke. I think this one should run nice

Manual states up to 15% nitro until after break-in. I will have to check on the oil requirements...

When i stare at the box & build of the engine, it reminds me of the good ol' days

...have not flown in months. Been busy with 'Life events' and such.
Played with Simulator at lhs the other day, did well.

Wife is doing a little better and has been asking to go fly (she watches)

I usually fly my mini and micro planes but would like to take my Gen1 Sukhoi, Jug, or Ultimate2 out to a place in the country.
Those '2200' planes are a bit much for the little parks we visit.

I may join a club this year, but it's already Fall.
Boy, i do like Fall! It went from 95F to 85F here, and i hope it drops to 75F. The shade during 85 degree weather is a joy.

I must have 'overdid it' yesterday because i did not feel like getting out of bed today. We have been moving and stuff.
I didn't get to sleep 'til late last night --additionally we have more errands later.

Just no way i was going to work today ...sometimes a working man just needs an extra day off.
Why? Because Americans are supposedly the 'hardest workers'.

I doubt that is true. I heard Japanese workers really put in some hours. Some of thier products have given American companies a run for thier money. Ford

I planned to make a little onboard flight video with my Jug (E-flite P47) but have not made the time. Maybe later this month before the trees lose thier color

I need to see some blue sky

I have my 'work bench' set up at our new place. Finally i can continue working on my engines and start assembling my used Easy Sport 40.
