where do i get parts for a saito fa-50 engine what kind of glow plug should i use from towerhobbies

Mikecam

Hi again gentleman. I'm getting close to breaking in my new 125 and I noticed some play (in and out) of the throttle barrel. I've read lots about Saito's having a spring in there engines and remember that the 125 does not have one. Should I be concerned with the play? Thanks

NO, none of my latest Saitos have the spring and none is needed.

Use the OS "F" plug from Tower Hobbies

Get Parts for your Saito 50 from www.horizonhobby.com Many of the parts in a Saito 50 are common with a Saito 56

Thanks Hobbsy, I feel much better. Tomorrow I start my first ever Saito, I'm starting to get rather emotional.

For Saito 125;3 blade 14x7 is ok.?.
Thank

Good luck with your saito mikecam

I've seen bubbles coming back up the fuel line from the refuelling valve occasionally,once again not always,while the engine is running and thought the same.I bypassed it and the fuel filter too..same problem.It's the angle on the photo,the main needle is about 5mm away from the bolt head.The engine feels and sounds tight and sweet.Fuel cap problem?

Hobbsy i'd like to see your prop figures for a 62a.I'm running 10% nitro and all synthetic oil.Top rpm i can get with the 13x6 apc is 8500.

rlmcnii i think a soft mount is mandatory when you tune an engine like i do..

I just ran my 2nd .62 a few minutes ago.
Fuel===WildCat 15% with 18% all synthetic
Plug===Fox Miracle
Stock exhaust

Bolly 12.5x6==10,350 home grown for you OF
Graupner 12.5x6==9.950
APC 12x7=====9,950

The HS needle is about 1.75 turns out from bottomed out and will barely run at 3 turns out.

I have a new Saito 1.00 and it has a spring in the throttle arm area. When I go to turn the LSNV the plastic arm will move in, the rpms will change and sometime the engine stalls. Is this the spring you say is not needed?

Thanks,
Bob

What's the best prop 1.00 combo for Sport/Aerobatic flying as far as performance is concerned?
Am installing it in an 80" Goldberg Decathlon

14-8

sodbuster 1

APC my best bet?

w8ye

My Feedback: (16)

Yes,

But actually there are a lot of variables in propellers and personal openions and perceptions often effect propeller choice.

If you only come across a Master Air Screw Black 14-8 it will be OK.

The Windsor Scimitar is an excellent prop as well as others

Generally for sport use the JFZ Zinger wood props do not seem to run as well on the ground

Top Flite wood props do not pullas well on the ground as do APC props

Wood props do not idle as well because they weigh less

andy530

what is the difference between a wood propleller and a plastic propeller? what is better? also i have a saito fa 50 what size prop should i use it has an 11x7 prop on it. it is a trainer plane

w8ye

My Feedback: (16)

There's not necessarily anything wrong with the prop you have on your plane.

The plastic props are more resistant to damage from ground strikes or hanger rash

The engine will idle lower with a plastic prop because it is heavier and offers more flywheel action

Plastic props are thinner and the engine turns up more rpm on the ground

That's the one Bob, my 1.00 may very well have one if yours does. My 2.20 and 1.25 do not have them. I'll check the 1.15.

BobMaine

Interesting... I'm having a heck of a time getting this engine to smooth out, looking for all the things to try that I can find. Maybe I need a new spring!

Hobbsy

My Feedback: (102)

Bob, where is it running rough, idle, mid or at full throttle. Normally a rough Saito or a thristy one is set too rich. A Saito will run so rich its scary then folks are afraid to lean it enough thinking they're leaning it too much

BobMaine

It is roughest at mid throttle. The whole airplane shakes so bad you can't hear the engine running.
That would be me about leaning. I keep hearing about "running it too lean" and the consequences that could happen. I'll give it another go this weekend will try it leaner.

Hobbsy

My Feedback: (102)

Bob, you don't need to worry too much about getting it too lean in the midrange because it will just quit. Peak the HS needle before doing any midrange leaning. That will help a lot. Peak it very slowly, sort of sneak up on it until it begins to slow slightly from being a little lean, then go back maybe one click on the rich side of the peak.

Some Saitos have a null or dead spot before you get it lean enough. My .72 fooled me until I went ahead and leaned it out another full turn or so. It would start to sag but wasn't putting out the power it should, so I kept on going until I got past that null spot.

I hate to ask a stupid question but here goes. I'm getting ready to fire up my 125. Manual says to add some ARO before first start up. I have read that dexron atf oil is good for that purpose. I have dexron lll, will that work or should i go buy regular dexron. Thanks

My Feedback: (14)

I don't think it will matter at all. The point is to have some kind of lubrication in the bearings and lower connecting rod during the first few rotations of the engine. What you have should work just fine.

Just don't be tempted to use WD40. It isn't a lubricant, but lots of folks think it is and then try to use it as one. Big mistake. You may know this, but others do not.

Mike, there is already a black grease in the crankcase, Pic. #1 shows it undisturbed, pic. #2 shows it working its way out with the oil.

how do i take of and land can i do this in the grass. i know this is not about engines but its about what the engine goes on. i have a trainer airplane with ab out a 3 1/2 ft wingspan
