Thanks to all for your input. I kinda knew what the response would be and took the shields off. Now I can order another set to replace the one I got too aggressive with trying to open with an awl. I used a little too much force and punched all the way into the bearing cage and bent it slightly. Oh well, they say practice makes prefect

John, what you're experiencing is more accurately called'' tortional impulses'' caused by a light engine, flexing mount and powerful power pulses. Set everything up as stiffly as you can, for example H9 aluminum mount, wing bolted on tightly etc.
Great advice. I changed the mount to an aluminum mount. Had to redrill the mount holes in the firewall (not a problem). Just got back from flying and everything was great. No wind for a change. I made a mistake in the previous post. This is the Spacewalker II 1.20 ARF from Horizon Hobbies, not the Sig Spacewalker. The Saito 1.80 really pulls it through the sky. Most flying is done at half throttle. Thanks again for the advice, Hobbsy.

I use only the aluminium mounts supplied by Saito for all their various engines. They are pre drilled for the particular engine good looking and last well even if you have the odd arrival verses proper landing and at the end of the day don't really cost that much more (especially given the time saved and the fact they come with all the necessary screws etc than other mounts, and of course problems such as yours do not arise

blw,
While you are assigning numbers, please add one for me.  I currently have a Saito .82a, .82b, and .62a.  I have been reading these posts for over a year now and really appreciate the advice and help provided to all who ask.  The information has helped me with the tuning issues I had with the .82a, and in taking some of my dad's old motors and getting them running again.  I might add that Kroil penetrating oil works very well to loosen up an old motor.

May as well give me a number as well. I've been here for a while and have several Saitos: 45, 115GK, and probably others in my collection... Will that give me member number 700?

Oh boy! I've started a membership drive.

For an update, (2) 30's, a 62, a 72, (3) 82a's and a 100.

All putt-putt nicely at idle, purr in the midrange and punch out power at full throttle. Can't remember a dead stick with a Saito, with the exception of running the tank dry a time or two.

15 X 8 is too much prop for a Saito 65

G'day in FNQ. Do you use the standard carby or are you using a very long ram tube/venturi with a Cox or other needle valve arrangement? I have seen setups like this on old OS FS 60s.

And I guess you are not using a standard tank either? Small metal tank?

I have one 85% Lanzo Bomber which I play with but do not compete. It has a Saito 62 and just about goes straight up on my standard fuel. It has been suggested to me to use lots of castor, lots of nitro and a bit of methanol but I am just playing so I have not bothered.

We had a lot of fun with two of my Saitos a couple of days ago. I have a newish FS-40 in an 80% Astro Hog built from a short form laser cut kit. It flies amazing well. Who said air bleed carbys are no good? It is brilliant.

And we had some fun with my 150S in its ARF Four Star 120. My mate from another club was having so much fun he ran it out of fuel. Twice.

Brilliant engines Saitos.

A 15 x 8 is just about ideal for the Old Timer discipline of Texaco. The engine runs at about 4500rpm on an electronically mixed throttle set up that gives about 6500 for take off and then the fixed throttle set up is settled to gve a constant 4,500 approx (depending on the day) for the climb. As for being to much this engine has done 400hrs flying in this regime (it is a dedicated Texaco engine running on 10% nitro 20% castor / cool power / klotz the rest methanol,) it is an old Saito, that I bought new in Hong Kong in 1993 and started using in 1997, always had after run after the lean run at then end of the day and is about to get its first set of bearings

I use a standard carby with a mixed fixed and normal throttle. The normal throttle for take off (6,500 rpm) and fixed for the climb (via the mix switch and flap drum switch) at 4,500. It is in an85% Bomber ARF (from the Vintagent guys that imported them)
For your 62 readSaitos specs I think you will find they recommendsynthetic oil not castor,and 10% for Texaco and 40% for Duration is about right. 14 x8 to 15 x 8 propfor Texaco and a Bolly 12x 6 or 13 x 6 works well for duration if not Bolly try Taipan or APC
I have had to fit a new 65 for theDalby Do in June cause the old motor isdying and considering theamount of time (engine hours) since it has had someTLC well no wonder. And with 2000 k's to travel (each way) I want to be inwith 1/2 a chance of whopping the southerners (cockroaches) from over the QLD/ NSW border
I am moving in to large scale a/c (a bit) and am going to use the Saito Gas engines I already have a 30 and a 36 for my Storch and Swordfish projects

With regards to your 62 with the right amount of steroids (nitro) you can even give the 3rd gen YS 63 a reasonable run with the extra few seconds engine run you get over the YS

Trust there is some food for thought in that lot for you

Do I get a number, can't remember if I actually joined, if I haven't consider me in (please)
For the record my Saito collection is as follows, 30, 50, 56, 62, 2x 65"s, FG20 and FG 36. I had to actually break into my stash and break out a new 65 cause the old one finally gave up the ghost and needs new bearings not bad after some estimated 400hours of flying, mostly Texaco but with the occassional Duration event.
Irun other 4 strokes but since being exposed to Saito in Malaysia inthe early 1990's I haven'tlooked back.
Just a thought my most memorable crash to date was with aSaito in Malaysia (on thethen Commonwealth gamessite at Cheras) when I mis calculated a turn and turned into a construction crane with my Saito 50 powered Goldgerg Cub, the silence was deafening except for the tinkling of the Saito as it made its way to earth through the structureof the crane boom, laughable nowbut devestating at the timr\e

G'day in FNQ, Cockroach here in Dubbo. I am not a real Oldtimer participant although I do belong to SAM 1788. Mostly I just like reading the articles. The bloke I know at Canowindra is a very keen oldtimer flier though and he builds beautiful models to put his motors in.

My old timers at the moment are the 85% Bomber with the Saito 62 and a half size Dalaire Sportster with a PAW 1.5 RC single ball bearing diesel. I also have two Heron Gas Buggies. One is elecric and the other has a Silver Swallow diesel.

The Saito powered one gets the most flying on nice warm days when there is some lift about. It will stay up under these conditions for ages after a 30 second engine run.

I am not interested in competing. I just like building weird models and flying them.

Thanks for the info, it was interesting to see a different perspective from the one I am used to.

I must build something for my old OS open rocker 60. I do have a short form Dalaire kit but when we moved house the plan went missing. I think I need to chase up another one.

At the moment I am building a Sig Four Star 40 which will either be moderately powered by a Saito 40 or overpowered by a Saito 62.

Cheers from South of the Border.

Kostass, I managed to scrounge up two figures from about 2006,

Saito 1.20 with APC 16x4 and 20/20 fuel rpm==10,000
Saito 1.20 with APC 16x6 and 10% fuel rpm===9,300

Your fuel should do 9,600 or 9,700

Hobbsy i appreciate your help!
Thank's!

I wish i didn't forget to buy a 9V battery for my tach. to measure the rpm's.

For a 13-14lb sport plane what Saito would you suggest ? A Saito 150 ? (....from Saito line. )
