Yo Troops,
On my FA 65, what is the small hole between the front cam cover bolrs for?
TIA, Sarge

Sarge:

If you're talking about the hole indicated iin the picture, there's a set screw in there that holds the axle for the cam shaft.

mate you couldn't possibly be that fat!!!

You can get the crankshaft out without a puller. First, dismantle the engine: back plate (pull the carb/intake), lift the cylinder – disconnect the con rod, take the rocker pivot pins out along with the rockers and push rods. Now remove the cam gear housing (top front of the engine). Lay a towel on a piece of plywood; then, put the back of the engine on the towel. Screw the prop nut level with the crankshaft rod. Use a hammer to hit the prop nut/crankshaft rod. Pull the crankshaft and heat the crankcase to the get the bearings out. Now follow the William Robison instructions.

Oh my....

Usually the crankshaft will almost fall out if you just heat the crankcase in the oven or with a Monocoat gun.

I remember the days before electric starters, and I have the scars to prove it! <G>

On the first two fingers of my right hand, the back of the first two joints - what looks like skin is solid scar tissue.

Haw.

the electric starters were only for the speed engines, with the thin props trying to hand start usually ended up with a broken prop and blood from your fingers.

I flew "B" speed and we didn't have electric starters. They were inertial starters that were crank driven and had a big flywheel to keep them spinning when the spinner was pushed into the cone. Electric?? new fangled stuff.

I just ordered a Saito 82 which I am going to use on a profile plane. Given I will use it for 3D flying I plan on using a 4 pitch APC prop. I also plan on running 30% heli fuel. Having said that, my question is what would be a good prop for break-in? Once the break-in has been accomplished, what would be the best prop to use?

Thanks in advance to all,
Keith

Inertia starters? I didn't mention them, they were even cheaper than the car starter and battery. An 80:1 gear box that was originally the starter on a Stearman or similar plane. Frame mostly the same as for the car starter, but the legs were longer so the person cranking could hold it down with his feet.

And may I point out, Bruce, you were still not hand flipping the speed engines.

I bought my first four stroke, a Saito 125 and I've put 10 flights on it now. It has been great. My only complaint is the very brief manual. I would love to receive a copy of a guide on these motors.

I was a little frustrated during my last 5 flights, I've been trying to lean the motor out from the initial five turns out on the high speed needle, but I couldn't get my 16x6 APC prop over 7,600 rpm. I've been afraid to run it too lean, and I didn't expect to have to go past 3 turns out, so I've been flying it really rich. Today finally, I cranked it all the way down to 1.5 turns out and it went to 8,200 rpm and flew much better. It might do even better more lean, but I haven't tried it yet. I think that I'm going to try a pressure regulator. When I refuel and pull out the stop on the exhaust line, there is plenty of pressure in the tank. I've also read so many good comments about a carb stack and filter that I think I'll try those too.

Huck:

Welcome sir, glad your engine is pleasing you.

You will have a greater all-round performance increase as you lean the low speed adjustment. A strange characteristic of the Saito carbs is that the LS adjustment is effective up to a little more than ½ throttle. Until it is leaned to a good running setting your fuel economy will be poor. Because of the extended range of the LS adjuster, set the HS needle only with the throttle full open.

Order the SAI50GK93 stack, the Bru-Line 202 fine mesh filter assembly, and spare elements as the Bru-Line 204. All are available from Horizon Hobbies.

You are Club Saito member number 318.

And again, welcome.

13x6 for breakin, 14x4 with 15% nitro, and 15x4 with 30% nitro.....

Ah, but I DID handstart speed engines during the break in.

During the fifties I NEVER saw one electric starter at ANY spped event. All inertial starters and nothing else. Even into the 60's I never saw electric starters. Wasn't until the 70's that the electric starter became prevalent.

Ernie:

A 14x4 on a 125 is Waaaay too small. I run a 14x8 on an old OS FS90and it tachs a bit over 9000. I run a 14x6 on an old saito 80T twin.
A 14x4 on a 125 would tach out of this world.

Does the SAI50GK93 fit the Saito FA-100 motor ?

Hi Bruce, he was origionally asking about props for the Saito 82. It might have gotten lost in the shuffle.

Well it looks like Ol Betsy is gonna live!! Today on a bench mount she turned 11,000 rpm with no hiccups. Now to try and get the LS dialed in. FA-65 with 13x6 prop. When the throttle is completely closed< I assume the engine should die. Then how far should the throttle be open at the correct idle rpm and mixtere?
Sarge

Ernie Misner

Yes Sarge, the engine should die when the throttle barrel is closed. That is a safety feature. Your throttle trim should be set to just completely close the throttle when necessary. There is no "set amount" of opening to get the right idle speed, but if you look into the intake you will usually see that the barrel is barely cracked open, 1/16" or less. Just keep going leaner on the low speed needle until you can get a nice smooth idle. Go too far though and it will die when you hit the throttle hard.

Hey guys I've picked up a Funtana x100 and was going to toss my Saito 1.50 on it. I want full 3d so I was figuring on running a 15x4w prop....ya's think this would be alright or am I going to push too much rpm?

piper28

Hmm, ok, I've finally gotten around to trying to get this 100 ready. I've lubed it down as recommended, however it seems that one of the rocker arms is completely frozen into place. (Well, either that, or the pushrod under it is stuck, can't really tell which). I figure I'll let it sit overnight and see if the atf fluid works it's way in. If that doesn't work, any suggestions?

Ernie Misner

They are shipping the Funtana X's now??? Great.

Piper, has the engine been sitting a long time? If the oil has become congealed and frozen, try heating the engine up with a heat gun.

I have a Saito 1.82 Twin, what prop would be ideal for this motor running on 30% fuel?

Thanks,
