RE: Welcome to Club SAITO !
Liquids actually can be compressed somewhat. It is just a lot harder than
compressing gases, that is, it takes a lot more energy to reduce the volume
of a liquid than to reduce the volume of a gas by the same amount. Solids
also can be compressed, but since they are condensed phases too, it takes
much energy.

Gases are compressible because there is a lot of empty space between the
individual molecules, so it is easy to confine them to a smaller volume. A
gas, any gas, at 0C. and 1 atm occupies 22.4 liters / mol. In contrast
liquid water occupies about 18 ml or about 1.8x10^-4 liters. In the case of
liquids and solids the molecules are almost "touching" one another so they
resist further compression.

Hello; imsofaman; What would you like to know? I have 4 of those 45's and think that they might be the best all time four stroke model airplane engine. You can use 5 to 30 per cent nitro, even 0% will work. I use an 11 x 7 prop, but 10 x 8 and 11 x 6 work good Too. No need to put a muffler on it either, since it's quieter then the Saito 50 that replaced it.

I wanted to know to begin with...is it somewhat powerful? Used in 40 size planes? And of course the prop sizes. I got a reply from a guy on another forum who actually uses a 12x4 in a Sig Rascal 40. I think that is pretty much what i want to do...but min is going in an autogyro. Thanks so much for the reply.

I must say that it totally amazes me that I spent 34 yrs. designing and building industrial hydraulic systems, pneumatic, and lubrication systems and find out in just a few posts that I never knew anything about what I was doing. Who would have thought it. When I was taking physics and advanced physics we somehow missed the theory whereby a gas or liquid increases in pressure when passing from a small area to a larger area. We always found that the pressure dropped. I guess the professor whom I studied under (also head of the physics department) must have been missinformed. Sorry I gave someone wrong information.

Yes that is correct. But for practical purposes in most industrial applications (hydraulics and the like) it is acepted that liquids are not deemed to be compressible because of the low operating pressures (3,000 to 5,000 lbs sq in) imposed by design.
If you take the pressure way up (20,000 to 50,000) then yes you will get compression.

Can anyone send me a link or the web address for Kelco mufflers? I want to check on one for my Saito 325.
Thanks,

Saito 182T DP
Set both High Speed needles at 5 turns.
Set both low speed air bleed screws half way across the air bleed holes on the front of the carb.
Fill tank and prime engine by holding finger over the end of the exhaust pipe with the pressure tap
Put glow power on the rear plug of both cylinders. The front plugs will light themselves after the engine gets to running good.
Start engine and go through the normal break in procedure.
Then begin to get the needles set.
Set each high speed needle for best running of the engine. Treat each needle individually.
Then your low speed screws work backwards. To screw them in makes the mixture richer and to screw them out makes the mixture richer.

RE: Welcome to Club SAITO !
I have an opportunity to purchase a Saito 82 from a club member for $75 and need some advice as to possible repairs needed. He claims it was run on only 1/2 gallon of fuel (30% heli). During that time, he says he leaned it out too much and believes he damaged it. While holding the engine in my hand with no prop, it was at first difficult to turn it over, like it was frozen up. After working the prop nut with my fingers, I did get it to turn over, but it seemed rough. The point is, if it only needs bearings and some other minor work it would be a bargin. However, if it requires a new cylinder and piston I think it would be smarter to just buy a brand new motor. Maybe I should ask him if I could disassemble it? He think's he can send it to Horizon and have it repared under warranty. I'm not so sure about that. How bad could it be damaged? The seller has a collection of 27 to 35% 3D planes and a little Saito 82 isn't much of a priority. He's just cutting me a deal to get rid of it.

I would buy it and repair as long as its the bearings... But 1st, try to take it apart behind his back to find out the truth...my two cents

What is the club saito all about and why and how do people become "members." I've just seen on some peoples post, it will say like "club member #xxx." It's prob. a dumb question but I'm kinda new to these forums.

But then again, I'm one of those guys who can't see the sense in paying three times as much for the same product just to cover the fancy packaging :-)

Hello, I am still waiting on my member no. Did I miss it somewhere? May you all come home with the same no. of pieces as you left home with.

RE: Welcome to Club SAITO !
I've got a Saito150 inverted,,Cline reg, Ram onboard glow in a FW190. Reason for the regulator is tank height. System runs fine but was wondering what the best routine is for pressurizing the tank after filling up ?
I've been throttling up WOT (onboard glow rx setting to 1/4 throttle or below) Fuel and pressure dots back in place,,, thumb over exhaust while turning prop over (counter clockwise) till it gets hard to do so. Is there a better way that will help me get fuel to the carb quicker after tank is pressurized ?

I'll second that! I've bought quite a few bearings from Paul at RC-Bearings now and they're all working *very* well. I was also delighted with the excellent speed and efficiency of his service.
But then again, I'm one of those guys who can't see the sense in paying three times as much for the same product just to cover the fancy packaging :-)

I have dealt with Paul several times over the last half decade (anyone remember Paul's Raptor .46 engine? <G> and have always been pleased with his prices, service and demeanor.
