I'm half way between 74 and 75 and raising a 10 month old.

I need some opinions I have a 70" wingspan Seagull Decathlon that had a Saito 72 .I am replacing it with a Saito 82 and I wanted to know if a 14 x 6 would be good for scale flying and ease on the engine?

Hobbsy

My Feedback: (102)

The .82 comes real close to the .91 in power, the 14x6 should be perfect. Even though the bore and stroke of the .82 make it seem like a short stroke engine, it is a real torquer. A willing worker if you will.

Pearl dave is on the money,you'll notice a big difference between the 72 and 82 on the deccy,i have one and first flew it scale with a 62 flat out everywhere then with the 82 you can go vertical on a 14x6 apc and saito ss or osf plug.

ps i've found the perfect after run oil mix when you finish a hard days flying.It's a big glass of navy rum with a dash of castor

It will do 500 foot loops with a Fox Miracle Plug I'm a Sangria man my self. More on the 1.25, maybe today, by the way Pete, the APC 15x8 came yesterday and like the 16x6 is perfectly balanced and the hole is where it should be. Landing Products has obviously improved their mfg techniques.

I don't know about the 15x8 Dave. Let me know how it runs. I was using a 15x6 to get those 9000 or near-9000 numbers on my 125.

A well aged 72 is a fine engine, imo. I really like how mine gets on the torque and sounds great. But, the 82 sounds great and runs great in the first 40 minutes. The 80 is rated at 20% more power over the 72, but there's more to it than that like Dave was talking about.

My FA-91 turned 9700 with 15 x 5. That's about a dead heat as far as HP/Thrust.

Even when you deduct the 200 RPM from the FA-91 numbers to offset the advantage of CDI over GI it's still only a very slight advantage for the FA-125.

Again, the results where not achieved on the same propeller/day/location/atmospheric conditions so it doesn't really prove anything definitively other than there is no obvious significant difference.

I have a 72 in my Something Extra, and it is a little power house. One time I was taking off and was about to run out of runway due to tall grass, so chopped throttle, and just as i did that, the plane decided to lift off, so I firewalled it, and it pulled the plane straight up. Good little engine and getting better the more I run it, getting good fuel economy too, I have yet to fly long enough to empty a tank. 15 minutes and I still have at least a half tank.

It too does not like Castor based fuel. Even a 50/50 castor/syn is not liked. I have an OS gemini 120 in a 10-300 that I am going to maiden tomorrow, and I will see how it runs on the SIG fuel. My other OS ( I have 3, don't hate) on my LT-40 seems to run OK on it, so hoping the Gemini runs OK on it so I can use up my last gallon of it. My third one is a 90 2 stroke, I don't use 2 strokes, but it was a freebie and its in great condition, works good as a paper weight. Same guy who gave me that also gave me a Saito 91.

I have 7 Saitos, 3 OS and 3 Magnums, guess which ones are most used in my planes.

Rudolph Hart

Dave could you explain what sangria is and does it have castor in it?

Acdc what size tank to you have on the 72? i use a 14oz tank flying the 82 and that will get me a safe 10 to 15 minutes with different needle settings and flying style.

Sangria, about 11% alcohol, I run very smooth on two or three glasses a week. Our local grocery store carries the brand shown.

Pete we gotta talk about the new Harley V-107-8 and V-114-8 combustion chambers. An new direction that makes sense.

PS, I now have the 15x8 APC and 15x8 Xoar in hand, the 1.25 is in the PSP with an Ironbay regulator attached, (for fun). I have a new ring and bearings for the well worn FA .40a, the little one in the picture.

That FA40A was bought new in 2007 if it is the one you got from me. It was used on a 50" Robin Hood built scratch from re-sized 100 plans. The engine was bought from Hodges Hobbies in Andersonville, GA.

I would proceed with caution on the ratio of Rum to Castor Oil, otherwise you could give a whole new meaning to the term "Sloppy Drunk"!

FlyerInOKC

My Feedback: (6)

AH! I had a friend that ran a bike accessory shop (I bought the fairing for my first motorcycle there.) he would refer to that as Spanish Biker/Pilot lube! One of his distributors gave him a can a beer in the company's blister packaging. It hung in the shop for years.

Thanks Jim, I ran it the other day and it was down on power compared to the old FA .40 I have so I'm going to freshen it up a bit. It's a great engine. If you have any extra Saito boxes, let me know and I'll shoot you some funds. Thanks again,
I'm headed to the PO to ship my NIB SuperTigre 4500.

Or why cafe racers raced from cafe to cafe.
There is also an at-the-table made "Spanish Coffee" that will keep you awake while still being very drunk afterwards.
But, I like my rum on the rocks and sipped in "moderation"

A late PS. Jim, would you know any particulars on a 1.20 that came in a box like this. Thanks

My Feedback: (16)

That's a intermediate new type 120. The head/intake manifold are different from the last designed 120S. It runs good but you cannot get a head or intake for it. They only made it a couple years. It has the high cam and big valves. The internal parts are same as the latter 120S.

I had a 56 in my last something extra and it would not knife edge
does the 72 in that plane help

acdii

Nope! Nose will not stay up on knife edge. It will pull up into a nice vertical, but not unlimited even with the 72.

Rudolph Hart

Thats cause your fuel tank on the 72 is too big you wally

Dave that 40 looks nice.I thought apc grey was ugly(and it is)but whats that brown thing?

If you mean the new watercooled heads yes bmw and others have been doing the same thing for low compression twins of all types for a while as the retro theme dominates style at the moment,practicallity too.Crazy thing is i'd like to ride a two stroke triple kawasaki 500 again.Even if you only ride it to the nearest cafe strip and it hardly gets off idle the youngin's reckon it ain't worth riding unless it has the most horsepower in class,not much different than we were younger yes??

RC Specialties

I have a question. All of Horizons data shows the FG-30b to have a 14x1mm exhaust thread. I have a customer that claims differently. Horizon Product Support says it has a 14x1mm exhaust. Can someone please confirm.

liemtran75

Just to provide some additional information regarding the adaptor and muffler I got from Jim. The picture shows the manifold that came with my Saito FG30B. The diameter is definitely bigger. Maybe Saito made some recent changes.

RC Specialties

Liem,

Thanks for the photo. Something is strange with the Horizon data. Maybe other owners can help us solve this puzzle.
