What engine should I use for my H9 Funtana which should arrive today or tomorrow?

YS 63 or Saito 91

satio 100 if you can handle it O YEA

Saito 100, mines on the way!

ive heard the 100's too heavy. might have to use trans fluid

use a saito 72 it has all the power you will need this plane was not deisgned to do high speed viloent 3D you will tear it up with a saito 100 use a saito 72 it provides great reliable power and infinity vertical but not at high speeds and top speed going parralel to the ground it will go at least 70 MPH hope this helps

why the he// WOULD YOU FLY THE FUNTANA AT 70 MPH. MINE WITH SATIO 100 WILL ONLY DO ABOUT 45. LOW PITCH FOR 3 D .A SATIO 100 WILL NOT TEAR THE PLANE UP. AND NO IT WILL NOT HAVE ALL THE POWER YOU WILL NEED!!!!!!!!!!!!!!! AND I AM AT 836 FEET ABOUT SEA LEVEL. WELL IF YOU THINK BARLY PULLING OUT OF A HOVER IS 3D. IT SURE WON'T KEEP UP WITH A 21 POUND PLANE WITH A BME 110 EXTREAM ON THE FRONT.

im making a rough estamation buddy why do you have to be so dam technical about speeds its just an estemation. and it will have all the power i need i do harriers and blenders and i have made inverted and rolling harriers perfect with this engine and i compeat with it so for what i do it has all the power i need. What are you going to do with it DRAG RACE.

WELL THERE IS SOME DIFFERENCE IN 45 AND 70 .MAYBE THE DIFFERENCE BETWEEN HAVING FUN AND FLUTTER. DUDE THATS 25 MPH DIFERENCE. WHAT IF COPS DID THAT YOU WERE GOING 45 BUT I THINK YOU WERE GOING 70 .HOLY CRAP THAT WON'T WORK .IN CASE .I'M THE ONE THAT SAID MINE WILL DO ABOUT 45 . PROBLEY A LOT LESS NEVER OPENED IT UP STRAIT AND LEVEL. NOT 70 FOR DRAG I BREAK OUT THE WHIP . YES IT WILL HARRIER OR BLENDER BUT SO WILL MY PT 20. BUT THATS NOT ALL OF 3D WITH THIS MUCH POWER I MAY GO 4D

ok whatever you say i fly giant scale so this funtana is not my best plane. but i relly dont think 25 MPH is a bug difference at full throttle in 3D i mean weren not pylon racing.

chill out. who cares how fast or slow your plane flies...you're acting like you're 14 and you're having a fight during recess. mine flies fine with an OS 70 Surpass. Plenty of power to pull out of a hover with an APC 14X4w prop.

YS63, Saito 72, 91 or 100 or OS Surpass 70 are your options so far.

I got the YS63. 13-4W apc and Wildcat 30-20.

I have the Saito 100. Almost too much power. Too much useable power anyway. I NEVER go over 3/4 throttle and even that is on a high speed vertical climb. If you have to buy a engine get a Saito 72 or YS 63. Dont get OS 70 Surpass cause even though it makes almost as much power as a Saito 72, it weighs nearly as much as a Saito 100. That is why I used the 100. I had it and the OS but after weighing them i chose the 100. In fact, if you wanted to go with the cheaper route, you could use an OS 50SX. It is a very light and very powerful engine. Or heck, even a Thunder Tiger 46. Pair either one with a 12x4 APC or the Saito 72 with a 14x4 APC and you will have plenty of power. Dont listen to these clowns saying that "You have to have a Saito 91 or 100 cause it wont fly on a 72 or 46 two stroke." Well GUESS WHAT. Yall are full of crap. Maybe at 6000 feet above sea level a 46 two stroke wont hover it, but nothing is as good at that elevation anyway. Oh, and this is not just my $.02, THIS IS FACT.

Saito 72 in mine. It gives nice vertical.

that was exactly the point i was trying to make yet some people have to strike down others opinions but the Saito 72 will do nicely for this plane it was not designed to do high speed 3D keep it real and you will relly enjoy this plane hope this helps

I think it's ok for people to choose whatever engine they want but I get angry when they say "get the 91 or 100 it's the only way to go". That's bull*****. Many engines work well in this plane. Take your pic and enjoy.

Joe

I'm using a Saito 72 in mine, plenty of power for my style and it hovers well with it.

I just picked up an OS 61 FX for mine, but it feels almost as heavy as the plane. What would be a good slow speed/high thrust prop for that engine on this plane? I was thinking a 10/4 but if anyone has a better idea let me know.

Try a 13x4 I am running a 14x4 on a . 61TTpro and it does great.

Hey, don't put that 10/4 prop on that engine. It'll blow up. You need a bigger prop like the other dude mentioned. A 10/4 is more for like a 36 sized engine (even a 40 engine would be too big for that prop). I agree that the APC 13-4W or 14-4W would be good on that engine. You want the biggest diameter prop with the lowest pitch that you can get and still clears the ground by 2 inches. Even then, you can get bigger landing gear.

Joe

Thanks for the warning. That was one of the sugested sizes in the manual for the engine. I will have it installed in a couple more evenings. I'll just wait and measure when I have everything installed. I just want something that will keep the plane at a moderate speed but give me lots of thrust for powering out of a hover.

the apc 14X4w is the prop that i use. it provides a lot of thrust, so much so that the plane won't sit still on the ground even at idle. there isn't much room between the bottom of the prop arc and the ground, but the landing gear is pretty stiff so as long as your runway is flat there's nothing to worry about. i have an os 70 surpass II on my plane, but the 14X4w should work well for the 61fx too.

on the saito 72 you can use a master airscrew 13/6 thats what is recomended and what i found to work best.

Its not so much the flat runway, its the pilot that worries me with that little clearance with the 14-4. Most fields are grass around here.

That's what most people run into with the Funtana and the Saito 91 and 100: You have to run huge 15 inch dia props. The stock landing gear won't cut it. You should be fine though. Try the 13-4W first and see how your RPMs are. I'd be willing to bet it will work well. What does a 61 FX weigh with Muffler? I'd be would think around what a Saito 91 or 100 weighs.
