I have just ordered a funtana 90 and have looked around here on RCU and good gosh what a range of engine's people are putting on this plane.

For 3D flying what is the engine to use on this plane ?? An OS 160 seems obsurd! Yet a OS 91fx seems to small. And a saito 100 seems to marginal. So what are you guys using ?????

I'm picking up the airframe today- got the servo's, and the Saito 180 is coming in a few more weeks. I live at 5,280', so I lose about 30% of my horsepower on a nice warm day. Plus it needs a little extra nose weight anyway. Kyle is flying a YS 120- if you have seen that vid, well, it makes you happy

Can you ever have too much power? I don't think so. It just takes self control to keep it slow- untill you are on an upline of course!

I have seen the Kyle video and yes that boy can fly!!!! One of the reason's that got me interested in buying this plane. They ought to give him a comision . hehehe.

The only problem i have with YS is that they break the bank to buy and they are very ticky engines IMO but they are also power houses.

How about an OS 108 ....

I originally used a Saito 150 on mine. I didn't like the plane much mostly because of the weight. Mine weighed 9 lbs 14oz. The book says it should weigh 8.1 lbs. I thought I had plent of power with the Saito 150 but didn't like how "heavy" it flew. I was always colapsing the landing gear, breaking the tail wheel and breaking the tail supports. And it's the hardest landing plane you'll ever see. That being said, along comes Kyle. What an impressive video that is. It made me stop and think too. So I decided to give the Funtana another chance. But this time I'm taking a different approach. I fly at 4800' elevation so I feel I need good power too. I chose a YS 110FZ engine. I'm in the process of mounting it now. I'm also hoping to incorporate several other lightening ideas in hopes to get the weight down to about 9 lbs 4 ozs. If I can get there I think the 110 will do fine. I always use 30% nitro which helps with power and it just plane acts better in a four storke. I have high hopes for this plane now. At least I'm going to give it a second chance. So... I would recommend the YS engine. It is about the same price as a Saito 150. It also has the pump which is better for this plane. I have several of these engines but not in a 9 lb plane. But I still think it'll work good. Just my thoughts.
Thanks.

My first instinct would be the Saito 1.80. Does anyone have the output numbers for the Saito 1.80 and the YS 1.10? The Saito only weighs about 3 ounces more, so I'd be interested to see exactly how much power the YS puts out.

1.20 up............

Maybe i just need to cancel my order on this airframe. A 180 in a 60 size plane is rediculous. It has to be a pig to take that big of an engine to fly it.

Chad

Well . . . if it's any consolation, I'd put a 1.80 on any 90-size 3D ship . . . because I subscribe to the "there's no replacement for displacement" theory.

2.75 hp satio 180

Who ever said the Funtana 90 was a 60 size plane?

It says so on the BOX.......60/90

And by the size it is a 60

FUNTANA 90

A "PIG" it is not....far from it. It just has a lot of wing area and if you TRUELY want unlimited aerobatics then you need a large enough engine and that just depends just on what your flying style is and how wild you want to fly it.
Size wise.... with over 1100 sq inches it is way bigger then any .60 size airplane I have ever flown. Most .60 airplanes are more in the range of 600-700 sq inches.

It might fly with a 60, but it would need 1.5lb of lead in the nose to balance and would not be highly aerobatic. Ideally it was designed around the YS 1.10
There are a dozen engine combo's you can run in it if you wan to. If these are too much engine for your liking then this may not be the plane for you.

Mine has an ST2300 on it that I had laying around collecting dust so I put it to use in this airplane and its a great combo.

Yes a 1.80 is a bit over kill but there are plenty of engines from the OS 91 to the Saito 1.80 that will work just fine.

Dont let these guys befuddle you with "OHH you need a 1.80 to MAKE it fly" Use what you are comfortable with but do not under power it as it is a fun airplane to fly with ENOUGH power.

There is no substitute for cubic inches.... thats what the left stick is for.

Enjoy it as it is one of the better buys in this size airplane for the money you may find.

I'am not doubting that a 180 would be fun on the plane. I guess i need to rephrase my question. I want an engine that will pull this plane out of a hover and not cost 400.00. It seems that the OS 160 is a pretty good engine and not a bad price. Just seems that it would stick way out of the cowl.

Ok first the funtana is not a pig. Second it is the best 3d plane ive flown and does stuff like now other plane. I think they did miss label it it should have been a 1.20 sized plane but o well. I have a os 1.60 on mine and its perfect. Mine weighs 10# and it still flies very light.

I really don'y know why everyone is thinking that a Saito 100 is to small for this plane. I can understand a larger engine for the high elevation guys but for the most part the Saito 100 is great. On CoolPower 30% Heli mine hovers two clicks past half and pulls out very nicely. It tips the scales at 8 lbs 8 ozs. The key is to get everything as far forward in the plane as you can. I mounted the Rx battery 6.0v 2000 mah, and throttle servo on teh firewall. The Rx is up against the fuel tank. I did use Dubro Super Lite Wheels. They shaved 2.1 oz off. NO PULL PULL on the rudder! It balances right at 7". I also used Hitec HS-475 Karbonite Servos. ( 1.41 oz) This is the best flying plane I have ever flown.

That is Bizzare? You put the battery up front? With that Harley Davidson up there, I would imagine that you will need some tail weight. Mine flys just fine with a .91 OS and 30% Heli. It will hover, and pull out of a Hover. I built it light, and with bare needs, and it weights right at 8 lbs even... You guys put 350 Chevys on the front, you need HP to pull weight. Power=Weight Visa Versa...I love my .91 on 30%.

A Saito 100 only weighs 1.5 oz. more than your OS 91 and will swing the same prop at least 400 RPM more on the same fuel. Mine balances at 7". I highly doubt a Funtana will balance with with an OS 91 without putting your battery up front or adding lead. If you added lead there is no way your plane 8 lbs.

Five years ago, this plane with a 60 to 91 engine would have been thought of as one of the best flying planes on the planet. Everybody is now in the mode of MORE POWER......including me. Many people, will be very happy with this plane with a 91 or 100 engine mounted. I started with a YS 91 but have since gone to a YS 110. The 110 is all the engine I needed to make me happy. I now have plenty of vertical. Rudder is pull/pull so I didn't have to mount stuff in front of the firewall.

My buddy has a certified shipping scale and it tips his at 8lbs 1 ounce. My non certified bathroom scale shows 8 even. I added no weight, and I put the battery in the middle of the plane, just behind the wing tube to get it to balance at the CG for starters... I used Hitec servos, and a 7 channel Futaba RX. I dont know how you get a heavier engine with nose weight to go the same CG. I guess it doesnt matter, CG it and go with it.. Maybe the models are built with that much variance.

Did you do a Pull Pull?

I did not do a Pull Pull. I should post a pic..LOL. I started to do a pull pull, and I put a Dial indicator to the rudder for fun. With a good amount of stress, .003" was all of the play I found. Most of which was in the clevis, not the ball end. The elevator was .005". Not enough for me to justify the Pull / Pull system.My plane is as stock as stock gets and with recommended everything.

I like your tailwheel assembly. What brand and size are your using?

again... the ST2300 (1.40 size) has plenty of grunt and is reasonably priced about $165.00
ST engine $165.00 plus tax
Slimline muffler $55.00
18x6 Zinger Prop & spinner about $$45-55 depending on brand
can run 15% fuel

Now I have a Perry pump/carb on mine but it would run OK with the fuel tank behind firewall and using a uni-flow tank see at
www.rcaerobats.net for info on this engine and in the Acceleron link it talks about the uni-flow tank setup

An OS 1.60 is about $250 but is by far a bargin for the amount of power this engine puts out.

Smooth FLying...

Why did they not call this plane a Funtana 1.40 or something? I think on another board somebodyhas a DA 50 going on one. I am making motor mounts now to hang a 440 Cubic Inch Mopar big Block on mine..[&o]
