That's a hell of a box kev,where do you stick all the beer and ice??

One of our members was thinking about an electric golf cart for the same purpose. I was thinking about a Roundabout. Even a riding lawnmower with wide turf tires might meet the need and reduce the damage to the field.

I agree, I have many Saitos and my nearly 20 year old 80 has run a 13x6 always. It has been flying my sons Aerostar 60 for the last 10 years and still going strong. Also when tuning your saito I have found that the hot set up is you set the low needle flush with the housing and then adjust your high end for a clean run at full throttle. Works on all I have come in contact with from old 45s to the 180. Have not tried any twins yet but I am looking for one!

The low needle flush works with all the metal throttle arms.

The plastic throttle arms, the needle has to be recessed about 1 mm

How does the older Fa 80 stack up to the newer Fa 62? I ask because I'm regularly running one of either a 13x6 or a 12x8 MAS wood props on my 62 mounted in a Kyosho Bf109 ( 56" WS, 8.5lbs) and it runs like a scalded dog with both if I hold it wide open. only @2.5 gal or less of 15% through it so far, so I'm not sure it's even fully seasoned yet.

How long does it take before these engines really get good and broken in anyway? Seems like my new ones just continue to gain a few Rpm's each time out at the field and the really worn in ones that I've gotten as used motors have never disappointed me either.

My .62 turns a Graupner 12x7 at 9,450 on 15% WildCat.

I use one of my 62's all the time with a APC 13 X 6. I never used a tach on it but it doesn't sag any.

The FA-80 put 400RPM over the FA-65

It is well past breaking in. It could be that it will just get a little bit smoother as you keep running it.

Anyone know what kind of static thrust a Saito 40a puts out on 30% heli fuel. Im at about 6000 ft so any comments on how I might get the most power at this elevation would be appreciated. Thx

Hobbsy

My Feedback: (102)

Nobody could know that without knowing the prop brand, diameter and pitch plus rpm and even then only approximately.

paulsen

My Feedback: (2)

I was just wondering if anyone had any thrust readings and if they did they would probably say such n such lbs with a such n such prop on such n such fuel at such n such elevation.

In which plane are you planning to install the FA-40A? It's my favorite of all my saitos....

Im wanting to put one on a Mojo 25.

Saito 450 question....

I have my 450 mounted on a 1/4 scale Waco, using a McDaniel on-board glow system. The system is set to cut the power off to the plugs at about half throttle. The engine is still on it's first tank of glow fuel, so I'm not running it up to full throttle until after a few tanks.

problem... as soon as the glow system cuts off, the motor starts to load up and will eventually die unless I bring it back to a point where the plugs light up.

Is it too soon to worry about this? The needle is about 4 turns out, so it's likely running pretty rich, but I have screwed the needle in as far as 2 1/2 turns, with the same problem.

Should I just set the system to leave the glow on at any speed for the first several tanks?

Also, I set the glow system up according to the instructions.... only connecting the rear plug on each cylinder. I wonder if I should go ahead and send power to all 6 just to make sure the front plugs do get warm enough to run on their own.

My Feedback: (16)

Just the rear plugs is fine

reyn3545

Thanks... I'll keep the glow on throughout the throttle range and see how that effects tings.

Once it gets broken in, about where would I expect to keep the needle adjusted?

You want to adjust the needles for the proper fuel mixture.

frets24

My Feedback: (15)

With the plugs NOT energized when you get to that point. Until then it will tend to load up a bit less as you begin to lean it out and get much better when you start to adjust the low end mixture.

Your lower left cylinder (from front view) will always be a problem child and try to load up. Your McDaniel booster will take care of that problem, so you've already got that one licked. The larger radials are progressivly a little better than the baby brother radials in that respect as well. In the end you should see good results with the OB glo-driver set to come on at 1/4-1/3 throttle. Great thing about the McDan'l is if you do lose a cylinder in flight it's nice that you can generally throttle back for just a brief moment and get it back.

Saito says to consider it flyable after 40 minutes, but the low speed needle needs to be set after 10 minutes or you're just trying to break in a stone cold engine. That's the reason the plugs are cooling off and its quitting. Set the low speed needle with the HS needle at peak rpm. Very hard to do this in the plane.

reyn3545

I'll set the onboard glow to stay on until just about full throttle. That way I can still choke it at full throttle and force some gas in to start it, without the glow plugs turning on.

Half an hour or so of that should be plenty of break-in time so I can start tuning a little bit. The cowl is off, so it's a pretty easy process right now.

Here's a picture of the work in progress. When finished, it will be all yellow, with red stripes and trim.

Looks great! I'll bet it sounds awesome. The Keleo collector ring is nice as well. Let me know when you're ready to maiden. I'd love to see it.

reyn3545

It does sound great.. like a harley when it's idleing.

My only real concern is the age of the plane. I thought it was 2 or 3 years old. Turns out it was probably 7 or 8 years old. It's been sitting idle for several years, and it's in great shape, I just worry about all the glue joints. the wood has dried out a lot over the years, I just hope the glue holds up. It looks fine. I guess time will tell!

reyn3545

OK.. The Saito 450 made its first few loops around the back yard this afternoon, now it's into the basement for some prep work and a new paint job!

Here's a picture with the cowl mounted.. it hides a lot of the motor, but I guess that's what it's supposed to do.

You flew it with a glow engine before painting it? Oh noooooooo..........!

I wish you tremendous luck in getting a good finish.
