That 90R3 should be great just to leave it in the Kadet Senior.

Mike i remember seeing a pic of that sopwith camel could you re-post it and would the new 120 do the job?.I've seen one fly with the 90 and it was marginal.

G'day W8YE, yes, I think it will be staying in the Kadet. I did not really buy it to use but to play with and in the Kadet it is safe. The Kadet does not need a lot of power and is quite happy with the extra weight and I just like plodding around with the combination. If it drops a cylinder it is no real problem, the Kadet flies quite well with very little power. I think it is in there for quite a long time.

As for the Sopwith Camel, I have an FS-82a that I think will end up in it at some stage. I am in no hurry.

And Old Fart, the new 120R3 looks like they have replaced the cylinders from the FA-30 with those from the FA-40a. I guess it should go a bit better but I won't be finding out.

Just got my latest Saito; an FA-62 GK. I only paid for the silver version but the GK turned up and at a special price too. I am very pleased. Now for a model to do it justice.

I also bought back one of my Saitos today. It is a recent FA-65 (one of the last). I sold it to a friend and he had it in a model but he is a bit short of cash at the moment so I bought it back and gave him an old Saito FA-45 and a plain bearing Enya 40SS to keep his models in the air. I think it will go back into the Lanzo Bomber it came out of.

Cheers

Mike

The 115 has been sitting for 2 weeks. Ive been flying gas again. Think I will take it out this week before work and put a couple of tanks through it. Damn that 115 runs good. Think I will run the vent line through the fuse and exit it out the back, maybe that will help with the slime problem the Pulse has.

Don't know if you should run the crankcase vent line that long maybe someone else here could comment.The thing i like most about hearing the 115 run in the midget is the induction roar kind of snorkeling sound it makes on a quick fly by when you throttle off quickly and then hit it hard again,awesome sound mates

The vent line should be no more than 4".

I don't worry too much about the vent line length...... Sometimes I use large diameter tubing.

That is what I was thinking. Run a larger size tube than the vent can fill per pulse.

I put 120R3 on H9 Corsair60 ARF. It runs very smooth.
I use FA100Ti on H9 Mustang and 60T on GP Cub40. Both engine runs well also, I am much satisfied
with Saito multi cylinder engines.

A friend just bought a 450R and is wondering what size drill he needs to drill his prop hole. Says he couldn't find any reference to it in the engine manual, so he called Horizon (he doesn't have a computer). They were not helpful, as the 'tech' (!?) said 'I don't have a clue' (!!!). My friend then measured(?) the engine shaft and says he thinks the prop needs a 12mm drill size hole. I've looked on various Saito web sites but haven't found anything about the correct prop hole size. Is a 12mm drill the correct drill size?...and if not, what size drill is needed? Thanks..

The Saito 450R3 that I have (1998 version) has what seems normal to me, a shaft with two different diameters. 10mm on the end where the threads are and where the retaining washer slides over and a 12mm shaft close to the engine where the prop would set. Hope that helps; anything else let me know.

Thanks,

jimm

I will take a video next time if I don't forget to bring a camcorder to the flying field.
I do not have an onbooard glow, but it runs fine after low needle adjustment.
I broke in the engine with 2 tanks of fuel as instructed before flying.

So let me get this right, your name is Dick and you let your friend measure your shaft and its only 12mm? At least you could have used imperial measurements to make it sound better. Thats just some funny stuff. Cheers the pope

I don't know what kind of measurements you guys take, but I just bought me a used plane with a Saito 1.80 Golden Knight. Nice!! Haven't started it yet.
So, here's a few dumb question to bug you with (I honestly am not going to read all 800+ pages of this forum, I'll read some).
1. What is a good fuel to use? I want the minimum nitro I can get by to save $$$.
2. Can I use my standard starter or is it too wimpy for a 1.80?
3. Anthing I should watch out for? This is my first Saito ever and my first large engine (my next one down in size is a Fox .74 and I am still learning how to use that one). Other 4-strokes I have are OS 70 Surpass II, Thunder Tiger 75 4-stroke, and Magnum 52 RFS (which has been giving me trouble, maybe valve seats not right?)

H, I have run all my Saitos on 5% nitro at one time or another and they do fine on it. All except the little .30, it needs to idle at about 2,700 on 5%.

I guess I'm now a member, just bought a FA-100 today for use in a Aeroworks edge as soon as I can afford it.

Anyway, I have a question about it. I found it new in a hobby shop with a old price tag $269 USD. Then all the way home I'm thinking "I hope there wasn't any revisions that make this not a good deal" So did I screw up?

Thanks
Cory

The only revisions ever done to the 100 was different mufflers and glow plugs. They were just ongoing changes to make them the same as other Saito engines.

Run your engine as it is.
