What say you RCU. The engine ways a good bit less than the .75 ST I had designs on, I'm just a little new to four strokes. The LHS, who's been there pushing 50yrs, is helping me, I just want second opinion of this one.


I'd really like to look at a WM midget stang a little later down the line(I have a thing for GB planes, and slick racers.....) and I think this motor will end up on it at some point in time.

I'm a bit bufudeled on the subject, It started as a Saito 100 on a 4*60 and seemed to have morphed into a Sato 100 on a Tiger 60. Hummmmmm

I don't think the response is going to be much differnet though. I flew two 4*60 with Magnum 91 four strokes. It was a great engine/plane combo. The Saito 100 would fit right in. A bit more power and more braging rights than the Magnum. Go for it.

It will be a good combination and you will enjoy

w8 thanks.

camp- sorry boss, meant tiger, typed 4*(own both and had intended to get the 4* 60 till the LHS made me an offer I couldn't pass on the tiger). I edited the title, which I think you where looking at it while I did so HAHA.


What prop should I be looking to swing with the saito on this plane? I have no desire to do any type of 3-d(unless you count stall turns as 3-d), I like old school aerobatics, preferably with a little speed down the long pass.

Depends on your style but could be from a 13-8 to a 14-8 to a 15-6 depending on your ground clearance

txaggie08

Ground clearance is why I'm asking, I'm converting to TD and can play with main gear height a little bit, and tires(which I usually run the big dubro or dan brown(I think that was the brand it's been a while) to get a little more clearance.


might try that 14-8, should be a faster prop if I understand correctly...

w8ye

My Feedback: (16)

That is correct on the 14-8 and that is what I would use

The Dave Brown wheels are cheap, light, and don't have much drag.

But if you leave the plane setting around on its wheels they will get flat spots on them. Feels terrible at preflight but doesn't make any difference on take off and landing because the ground is rough

txaggie08

I've got a set on the 4* that flattened out, but that plane sat for a year on them. I need to build some racks to get the fuselages up off the ground I guess.


I've got a du-bro nylon gear for it that I think should clear a 14-8 prop, I'll have to check that out with the st(I believe, unless I've gone completely crazy, the GC with that motor and the 100 should be identical as the center of the thrust line is the same.).

The S75K version of the Super Tiger was pretty heavy

I've been to College Station back in the mid 60's. I was at Fort Hood

txaggie08

yeah we compared weights in the shop today. The st is something like 26ounces on a stuck muffler while the saito 100 is 19.

It's a darn good motor, and for the 75$ brand new at the LHS I paid for it I'll never say an ugly word about it, except that the *blank* thing doesn't like to run on it's side for some reason(nobody that played with it ever figured out why either.....). I had it on a hobbistar for a long time, literally flew the vertical stab off the plane, but it would yanks it up into something resembling a hover(that was cool to watch....I couldn't do it but hey).

Almost as much fun as the tiger .25 that my instructor gave me we flew with a tt .46 pro, with a bigger carb on it. My plane crashed and he gave me that airframe. Holy crap that thing was fast....

Man I see a lot of stuff coming in and out of fort hood. I'm originally from the Beaumont area, so we saw all your heavy hitters come through there on there way in and out. When I was reffing at a paintball field up here in CS, we used to get flights of all kinds(rand from f15's to longbows) coming in. Had a few of the helos turn around and circlethe field, I think the noticed us on the way by and where showing off

You probably have the G75 then. They are good engines. Keep it around. You'll never be sorry

For some reason the APC 13-8 pulls hard is the reason I lumped it in there with the 14-8

I had a Hobbistar for several years with a MDS 68 engine. I really liked it. I eventually lost it when the receiver failed

I enjoyed my stay at Fort Hood. I'd sneak off and fly over to Waco and drink a Dr Pepper sometimes. I enjoy Killen too but that place has really grown since then

txaggie08

They do not like doing full power outside loops.......the vertical stabilizer apparently likes to snap OFF when you do that.....


I will definitely hang on to the ST, I'm sure it will go on this plane when I move the 100 to something else . I've got a new spray bar assembly on order, seems mine was bent when the hobbistar crashed and I haven't flown in so long I didn't notice until I started cleaning her up it was messed up.

My Feedback: (16)

Be sure and get that spray bar in there at the same angle as the old one. There's a cut out on the bottom side of the spray bar that goes straight down when you have the carb out of the engine and are looking up in the carb from the engine side. The idle needle goes half way across this cut out when the throttle is wide open

I always ran mine on its side

One of these days, I'm gong to have to try a high pitch prop. On my 4*60, I used a 14x3w APC's on the Mag 91 . If I wanted speed, I would go with at two stroke and pitch it up, but I use the 4 strokes for their pulling power and pitch it low for that reason.. I never fly full throtle anyway. Besides slow and easy works for most everything I do these days

I tried a 11 X 9 on my Saito 72 and a Ultra stick 40. The plane flew around OK but the engine had such a rich mid range that I didn't try any vertical performance evaluation.

I took the engine off and tried it on the bench with a 13-6 and it ran fine?
