RE: Welcome to Club SAITO !
I'd be a little concerned about using all-thread for a prop shaft. Can you find a hardened steel bolt, perhaps at the home center? The carbon steel in that all thread might not be strong enough, and I would be concerned that it could shear....

When did Saito Quit including a Velocity stack on there Engines?
I just purchased a FA-62A AAC and it doesnt appear that it has the Velocity stack. The last engine i bought was a .72 GK and it came with a velocity stack. I'm wondering if it is a necessary item to have on the engine?
Thanks

I just purchased a 100GK and it didn't come with a velocity stack. I decided to put one on so I'd have something for my Bru Line air cleaner to go over.
After bolting the stack on, I found a gap between the carb and Velocity stack mounting plate. Is this normal or am I missing a gasket or something?
Thanks for the input!

Should I purchase A velocity stack for my new engine?

You can purchase a velocity stack as a separate part and put it on your carb. I bought and put them on a Saito 100 and 91S and they work fine. You will need to get a small O-ring to place between the stack and carb body to seal the air passage thru the stack. I bought the stack at www.advantagehobby.com and the O-ring at a local plumbing supply store

People,
Does anyone here have any first-hand experience with premature connecting rod failures in early Saito 3.00 twins??
I recently acquired a new, but older model, 3.00 twin. Somewhere (RC Report, I think) I read a little side-note about connecting rod problems in these engines. The service people at Horizon tell me they have never heard of this.
Anybody ever experienced this? Thanks.

RE: Welcome to Club SAITO !
Hello
I have some problems with the 125 Saito mixtures.
HS needle is 3 1/2 turns out and the LS needle is turned in about 2 turns from the factory set up. Idle is fine about 2000-2200rpm and response is really good.
When it runs at full throttle and rapidly back to idle it allmost dies (it runs very roughly a few seconds) and then get back to normal idle . If the throttle is moved slowly to idle it runs fine.
Is the HS still too rich ?

I read on the saito engine information web site that the saito engine Doenst like to be Throttled Fast.
Information from http://saito-engines.info/special_tricks.html
As the throttle is quickly advanced from low to full throttle lots of air suddenly enters the engine which will cause the engine to quit unless the low-speed mixture is set sufficiently rich. The faster the throttle stick is advanced the greater is the tendency for the engine to quit. Therefore, if the throttle motion is slowed down the low-speed mixture can be leaned further while still preventing the the engine from quitting when the transmitter throttle stick is rapidly advanced. See the ‘Throttle Setup’ section on this web site; it is best to have the leanest possible low-speed needle setting.
The amount the servo is slowed is a personal decision. Just slow it an amount you consider is the slowest you think is reasonable.
The overall result is a very reliable low-speed engine setting. No matter how fast you move the transmitter stick back and forth the engine will not quit.
Of Course only special radios can control Servo Speed.
Kinda sounds like the low speed needle isnt set right i would try to turn it out 1/4 of a turn at a time. my be it is set just a tad to lean. the engine starves for fuel when decreasing the throttle rapidly.
So turning it out a little bit will give it a little more fuel during the quick deceleration IMO
But i'm sure there Are others that will give input but thats what i would try if it were me. You can always put the needle back to were it was before if that doesnt work.

Most of the time they work just fine with periodic complete and rapid throttle movement if they are set correctly.
But if you set there and wing the throttle back and forth several times, it is highly likely to quit. Or maybe even backfire and quit.

RE: Welcome to Club SAITO !
Ok guys I've got a 40 sized Edge 540 with a 52 inch wing span advertised flying weight is supposed to be 3.6 lbs.
I am thinking about the Saito 82 for power, but want some opinions.
I want this plane to be fully 3D capable.
Will this engine be appropriate??
I notice the weight will be very comparable with most 46 sized two stokes.
Whaddayouall think??? JDXX

One reason is that air will accelerate faster than the fuel, so you get an initial charge of a lean mixture. At least that's what I've read in several places.
A Saito .82 on a 3.6 lb plane? I guess you would have hover power without ever having to worry! That would be 3D capable and then some.

RE: Welcome to Club SAITO !
I guess what I should have asked is weather to go for one of the smaller saito's.
Though I would like to use the 82 as it will fit for later projects I have in mind...
Thanx, JDXX
