Yep

Overpowering with the 1.80 is not such a bad idea if you keep the weight the same.

I have read more threads on Saito 150s and 180's and there overjoyed owners to see it anyother way.

I have been flying Funtana with a Saito 1.50 since last July, and I am still thrilled with it . If you use good throttle mangement, the 1.80 should be fine.
As far as planes being over-powered, I guess that most TOC and serious IMAC competitor does it. The purpose is not to fly around burning holes in the sky, but rather to have outrageous power "available" to do things that normally-set-up-planes with average power cannot do. That is why 35to40lbs planes at the TOC where fitted with 150cc engines. Well, that is also why my
-42% Extra weighs 35 lbs and has a DA-150
-33% Extra weighs 26 lbs and has a DA-100
..................and my Funtana 90 has a 1.50............................and I LOVE THESE PLANES

I don't compete, but I have a whole lot of fun.


Edited for stupid spelling.

if you think its is such a good choice of engine why do people keep putting threads about tail flutter coz?


come on you answer that?

Easy answer to that. They are not experienced enough to handle a plane that overpowered. Even a novice could see that a plane with the thrust to weight ratio that the Saito 150 or YS 140 gives the Funtana 90 requires extreme throttle managment control, thats 1st. 2nd This plane should never see full throttle unless in an upline. Remember the point is not to have a ferrari but more like a bulldozer. And the other half of the equation is dont skimp on servos and linkages. The best you can put on there nothing less than 70oz of torque and 100 in the rudder. No slop and sealed hinges. If you are not prepared to go that extra step and use common sense when flying then dont be suprised of what will happen. Coz

islandflyer

Thats right:
- I use Futaba 9402 all around (111 oz/in torque).
- I replaced any stock linkage component that was even slightly loose.
- I fly mostly at about 1/3 throttle: I have the stock tank (about 16 oz) and after a 13 minute flight I still have 1/3 of a tanf left.

For some reason I just dont think there was any thought in that last question. Coz .LOL

I agree. If you match it with the 1.80 then use throttle managment. If your the kind of guy that flys balls to the wall fast and wants to think you can 3D (though snap rolling doesnt count) then the 1.80 is not a good choice. But if you actually know how to use your left stick then you cant go wrong.

A friend just put a Saito 180 on his Funtana and it shakes the DOG out of the plane at idle. I have a Saito 150 in mine and it is a lot smoother at idle.

Run heli 30% and the plane should run better.

One other option for CF LG on the F90 with Saito 180 swinging a 18" prop:

I used Graph Tech #113 gear on mine. It's lighter than the stock aluminum gear, and gives plenty of ground clearance with the tail up.

This gear fits the Aeroworks Edge, so you can also order it from Aeroworks. I did this before when I couldn't wait for Graph Tech to re-stock. I paid about $5 more if memory serves, but it's worth it when you don't want to wait.

What do you use to seal your hinge lines?

joeb102072

My Feedback: (9)

I take a bit more care and time and use ultra coat what ever the wing color is that touches the hinge area.

C140 Brothers

whats the point of going saito 150 and ys 140 if people can't handle them you might as wellput the right power in it like a ys 110

joeb102072

My Feedback: (9)

Being able to handle them is soley based on experience. If you do not have it dont put one of those engines in it. Its simple as long as you maintain good throttle management and have good set up there will never be a problem. theres a guy in here who has taken his funtana 90 downline 3/4 throttle with a Saito 150 in it and not so much as a rattle. Rock solid. While I think the YS 110 is a great engine for this plane I believe the 150 and YS 140 are just as good.

The Y.S. 1.10 and the saito 1.50 are very close in power. So if you already have a 1.50 or 1.80 or you dont want to wait until the Y.S. 1.10 comes off of back order then its your only choice.

I agree with c140 the ys110 is ideal for this plane, however if you allready have a saito 180 you might as well put it in, and i know what your saying about the weight being of the s180 is 3 1/2 onces heavy then the ys110 is not much but its gonna need a bigger prop use more fuel then the 110 plus your gonna more then likely have to mod the cowl, but hey i think we can be too parnoid about weight sometimes in planes as im sure all the motors that have been talked about in this thread are fine(*not to sure about the da 150 though [>:]*) for the plane and you would not see much differnce in flight performance, the f90 has got plenty of wing area as long as you dont use the throttle with a on off switch with a big motor your gonna be fine! Jimbo let me fly his plane at the weekend!! it does hover!

If I could have got hold of a YS 110, I would have, or even bought a used one!, but they just aren't out there. I bought a 180. I will loose 3oz's with the carbon gear I needed to get for the larger prop. So now I see it as a net 1/2oz gain. I'll probably loose that with the 1/2" of wood I need to remove from the engine box so the gap between the motor and cowl will be right.

J.R uk

yeah right its a shame you cant get hold of the ys, must be really in demand there in the us, are you going to fit a pump to your saito?

My AUW with a YS 1.40 is right at the 10# mark tanks on CG both of them.

J.R uk

Mines about 8 1/2 pound, i got the tank before the the wing tube have noticed no cg change in flight and thought it might be a bit fiddley trying to get the wing bolts done up around the tank

What club do you fly at?

I was planing to use a 17x6 APC on mine with the Saito 180, and someone told me the prop would clear with the stock LG? Those of you running this motor or know guys who are, is this true? I plan to finish it tonight and maiden it tomorrow if I don't need other LG that is.

You may just clear the ground with that gear maybe with an inch or so to play with. TNT's CF gear $ 40 and its 2.5" taller thant the stock Hanger 9. I ordered it for mine. I am swinging a 18X6W. I def needed it.
