Welcome back. Haven't heard from you for a while.

All the FA-100 engines had the cams with quieting ramps. Use the 0.0015" clearance setting.

Does everyone's Saitos leak the afterrun oil out in a big mess after a day or two? I kind of hate putting it in there knowing that it is all going to come back out and be so messy. Yes, I plug the breather tube back up, but it seems to just come from? ..... seems like everywhere but I'm not sure. Nothing is loose or worn on the engine. I think this is normal because my 72 did it and now the 82.

Also, Bill or Hobbsy, is that you that pulls the rocker covers and runs some lube down in there each time out? I'm wondering why, because when I use an ample amount of after run oil and then turn the engine upside down while turning the prop a couple of times, it seems to pump the oil into the top end and everywhere.

Thanks guys,

Ernie

I put a big slug of oil in after running the engine, but I also spin it with the starter for 20-30 seconds after I put the slug of oil in. A lot of it blows back out, but I know it's well oiled inside. After this I'll get a few drops for a day or two, normally I'll tie a bit of tissue on the vent line, catches it all.

And I'm the one who pulle the covers and oils the overheads before a flight session. If you normally find yours wet with oil you don't need to bother with it.My 120 engines are usually dry, the FA-72 is generally slightly wet, the FA-80 almost always has plenty of oil. Seems it's really mounting position that makes the difference. Upright - dry. On the side - damp. Inverted, sloppy wet.

I plan on doing entry level 3d style flying - is this correct? I see postings of people using these huge props for 3d compared to what the book lists... what are the basics for selecting a proper prop size? My plane is a .46 sized U-can-do.
I use a 15x4W on my Saito 100 in a 3D profile ship and it's exactly the right prop for 3D. Mind you, I run just 10% nitro and those who run 20% seem to prefer a 16x4W.

Given that the Ucando's wing loading is higher than a profile ship you might be better off with a 14x6 -- but try the 15x4W anyway -- it'll give you a lot of static thrust, which equates to good pull-out from a hover etc.

Also, I noticed the engine was very difficult starting on the first few breakin runs. I couldn't imagine starting this with a "stick". I had to use an electric starter by "bumping" the spinner - meaning running the starter up and then hitting the spinner.
I bet you're trying to start it with the throttle open.

My Saitos (indeed all my 4-strokes) start best at a high idle. They turn over much more easily (thus avoiding the need to "bump" the starter) and they have better fuel draw so fuel gets vaporized more effectively before going into the chamber.

If you're not getting any firing after 5 seconds of starter, turn the engine over a couple of times (with the glow clip *off*) while placing a finger over the exhaust -- this'll push fuel into the carby. Then spin the engine briefly (just a second or two) with the starter, reconnect the glow clip and it should fire right up when you spin it over again.

Starting a 4-stroke with the throttle open is not only very hard on the starter but also a little dangerous because if it's lean it will almost certainly throw a prop -- with far more force than when at idle.

Thanks for the info Bill and XJet -

I've been trying to start with the throttle trim in the middle and the stick a hair less than 1/4. That was the sweet spot for my prior .46, so I used that as a starting point here.

I'm going to pickup both a 14x6 and 15x4W APC's at the LHS and see how they do once I maiden.

I have an 82a on a Twist and started it, this morning (6 degrees F) at four clicks above slow idle--with some help from lighter fluid. When I have someone else turn over the prop for starting, I go between all the way down and four clicks up. Somewhere in there it catches. Never a backfire. The Saito 1.0 starts the same way, never a backfire, though I used to have them when I "primed" the engine.


I love the combination: 15 x 6 Master Airscrew, 15% Wildcat fuel, 4.75 lb. Twist for 3D flying. Goes UP at full throttle in an inverted spin. The power has saved my butt many times in low hovers, windy condtions.

Hi Bill, Thanks for the quick reply. I was hoping that it didn't have the quieting ramps, with the method usaid to set the lash with. O well. Been out running it just to hear it run, it's so amazing. What is the technique for flip starting the motor. I did it once when I was breaking it in and haven't been ale to do it again. Same with hand starting it with a chicken stick. Did I just get lucky or what? It fires up right away with the starter but since I was able to flip it backwards and it started right up, I'm hooked. Thanks Tom.

If the back flip is working for you, continue.

Perhaps I should be ashamed to admit it, but I've never mastered the back flip. I just go lazily on my way, lugging my faithful electric starter along.

Bill, when is your book comming out? It is such a hassle to go through 70 pages of posts looking for something you know you've read. Can't wait to see your book. Tom

Oh, you impatient man! I've only been working on it for a luttle less than four years now, give me some time, for Pete's sake!

Haw.

In the meantime, I guess you missed my post about the Saito notes. Geerally covering about everything except down to the bottom overhaul, with subject headings even. Still a bit disorganized, but a lot better than what I first sent.

Send me your email either by PM of email in RCU, I'll dsemd you a copy.

The offer is still open for everybody else too, and if you want an update just ask for the file again.

Bill.

Bill,
I'd like access to your archives.
I put the 1.00 back together after replacing the bearings with ceramics and a double sealed front.
I just test ran a tank full on the test stand.
I was a little apprehensive since it seemed the Exacto blade trick for the cam gear was a little too easy.
It ran fine!
Also, looks like it's runny nose is cured!
I'm looking forward to enjoying the longevity of the ceramics.
Still no luck on the other engine.

Hi all,

First timer to this thread. I just bought my first Saito....an FA 180. Brand new, in the box, for $315. I thought it was a good deal.

Now, I just sold a H9 1/4 scale CAP 232 with an old ZDZ 40BS in it and am looking for a new plane....a YAK-54. I have my eye on two of them: The QQ 73" version, due out in May, and the Carl Goldberg 77" version, already out.

Because the QQ one isn't due out until May, I was really looking hard at the Goldberg one, but that plane weighs between 12.5 and 13 lbs with a Saito 180 in it. No one in the thread about that plane has flown it with a 180 in it, so I don't have any good flight info. The QQ Yak would be about 11-11.5 lbs.

Has anyone here flown an aerobatic plane in the 12.5-13 lbs weight class with a Saito 180 in it? If so, can you hover the thing with it? I'm not big into 3D, but would like to get something that I could hover once in a while and have enough power to have fun with.

Any help anyone can give would be great!

Thanks,

Rich

Guys,

Can anyone tell me what is the difference between a FA56 and a FA56F, the 'Fun Fly' version with the red anodized thrust washer.

Cheers from the Barfly.

The 56F has a smaller carb. Not much difference in the way they run. The 56F is not available in the USA

Enjoy,

I have run into a problem with my new Saito 125. Ive run about a gal of fuel thru it, and it has developed a terrible squeal. I ran about 1/2 gal thru it on the test stand, it ran great right from the start. I than put it in the plane and had about 6 flights for another 1/2 gal. Running it rich all the time, the fuel was wildcat 15% extra preium with 18% oil 20% of that being castor. I had brought it back to the flight line and was in the prosess of running it out of fuel to put it away, and it started to squeal. I shut it down right away, looked it over very good, turned it over by hand and could not see, hear, or feel anything so I started it back up, still has a very bad squeal. If I was to guess I would think a bearing has gone bad. Any ideas?

Sounds like you have lost a main bearing

Better call Horizon

Not to change the subject. In my 16 years in the hobby I have owned the following Saito engines:

45, 56(x3)65(x2), 80, 91(x2),100, 150. I currently have a 56, 91 and the newest is the 100.

Can I join the club? ;-)

I also have a soft spot for Enya 4-strokes.

You're in, number 207.

But I do wonder about that spot for Enya 4-strokes. Did you fall and land on one? No, that would be a "Sore" spot.

Haw.
