FuntanaS 3D - What Engine?
 
I just bought a hanger 9 FuntanaS 3D .40. I am trying to come up with the best engine to put in it. I heard that a .46 is not enough to pull good vertical. Anyone know for sure? Also, I heard that a .72 4-stroke isnt enough. Can somebody help me go VERTICAL?!?!?!

a 72 will pull it but it needs to be propped right,(13x4 or 14x4 for 3D) I have a YS63 for mine Still need to put it together)and the other at my club with the YS63 has great vertical, Many are using 90-ish 4-strokes but bringing up the weight ruins the type of flying this plane was designed for IMHO but that is up to you, It's a great plane.

I most important factor is how far above sea level you are flying. If you're at sea level, and I believe you are, the Saito 72 and YS63 are perfect for the plane. Plenty of power for whatever you do and they mount in the ARF much easier than the Saito 91 or 100. I personally like the YS63 on higher Nitro (20-30%). The YS63 takes some playing around with the throttle control rod since the ARF was designed for the Saito 72 which has the throttle on the opposite side of the engine than YS. If you want to just bolt it in and have less problems, I vote for the Saito 72 even though I have the YS63. It all depends how patient and good you are with re-routing throttle control rods and re-mounting servos (remounting the servo was the easy part). I had to put a 2 inch Z bend in my control rod and mount the servo on the left side. The Saito 72 would not require any mod to the throttle servo location or control rod.

So at sea level, the saito .72 will pull vertical just fine? What make is the YS63? Please pardon my ignorance...

Yep at sea level it has a ton of power, perfect for the FuntanaS. Above sea level the air is thinner and the horsepower of the engine goes down. For example someone in Denver CO would want the Saito 91 for the Funtana. Where I live the 72 would be fine. If you're a total power junky, the 91 and 100 would work at sea level too. The problem is that they take more work to get it into the Funtana's nose.

YS is the manufacturer. The 63S and .63FZ are 4 stroke engines.

Should I go with a 2 stroke or a 4 stroke?

RE: FuntanaS 3D - What Engine?
 
Go with a four stroke, they produce a lot more torque than a two stroke. This plane is designed for 3D flying, which requires an engine with a good bit of torque. A two stroke will fly the plane, but will not help the plane perform to its capabilities like a four stroke will. Plus, four strokes are just too cool.

I droped an OS 61 into mine and it flys like a kite.

I also recommend a 4-Stroke, I have the Saito72 in mine and im very pleased with it. Vertical performance is awesome. Im using Byron 15% with a 14x4W APC.

My Funtana flies awesome. It has a Saito 100 and a 15x4W APC prop.

hey cheech. i thought i screwed my cowl up drilling the mounting holes, but yours is like mine, with the drive washer of the engine down low in the cowl hole. I hate the way it looks, but a big spinner hides it well.

Was it hard to put the saito 100 in your Funtana, Cheech? Would I have to do any mods to the firewall?

Mine ended up that way too. It just seemed like that's where it wanted to sit when you slid it on. I never noticed mine was off center until I was done. No one will notice but you (and ME ..lol). Also I think there wasn't enough depth in my cowling to be able to screw into it without it sitting in that position. You run out of cowling to drill into..at least if you want to drill into the firewall like they recommend.

RE: FuntanaS 3D - What Engine?
 
Yeah, my crankshaft exits a little low. It's the bert you can do squeezing that engine in there. The only mod I had to do was to relocate the blind nuts that thay had for the engine mount. Working behind the firewall was kind of a pain, but no big deal. I really like this combo.

fairplay,

Six Funtana S have flown in our club. The engines have been; OS Max 46FX (2), Magnum 52 (3) and a Saito 72. One aircraft started with an OS 46, but was sold to another member who put a Magnum 52 on it.

Our field is about 120 feet above sea level. The Saito is the only one with spectavular vertical performance....not visibly slowing down on the way to nearly out of site. The Magnum equipped planes will climb nearly forever, but obviously are slowing down the higher they climb. My OS powered plane (exactly 5 pounds without fuel) is good for about 100 to 150 of climb before getting sluggish. The other OS powered Funtana (5.25 pounds) was able to perform the entire IMAC Expert sequence as well as holding a hover, but with nearly full throttle, and not enough additional power available to properly "lunge" out of the hover. Other than the hover and the height of verticals, the Funatanas perform nearly identically.

IMOH the great difference in performance with the Saito equipped plane is probably due engine ability to swing a larger prop, hence much more pulling power. If your budget allows I would recommend the Saito 72, otherwise pick your 2-stroke.

So will the saito 72 make it hover? (Thanks for allthe replys by the way):D

RE: FuntanaS 3D - What Engine?
 
Iv read this whole page, and people have been talking about what engine to put in the Funtana, Well i have a saito .72 in mine, everything is perfect in it, and NO i didn't assemble it heavier then the recommended overall weight its suppose to be at. I'm using 15% nitro and a 14.4 prop, Some people say they can pull straight out of a hover with that engine in it, but i cant. i don't know what the problem is, but my funtana will only hover on full throttle {LOL} no room for mistakes, I'm going to try to switch to a 13.6 prop, if that doesn't work, i think I'm going to have to stick a bigger engine in it like a 100.

JoeAirPort 04-12-2004 11:40 PM

RE: FuntanaS 3D - What Engine?
 
Go to 20 or 30% nitro and that will give you a boost. You should be fine with than engine unless somethig is wrong with it. Are you flying at sea level? If so it should pull out of a hover very strong. It should hover around 1/2 to 3/4 throttle.

RE: FuntanaS 3D - What Engine?
 
I'm going to try a 13.6 prop. if that doesn't work i guess I'm going to think about buying 20% nitro fuel. but that is very expensive. i dont think all that is going to help though because i would need a pretty big boost in order to fix this problem. no nothing is wrong with my engine, its only got about 15-20 tanks. Brand New. Does anybody out there know where is can get a good type of 20% fuel?? thanks.

Local hobby store has all sorts of fuel if there is one close. It's only a few more bucks per gallon for higher nitro. Try WildCat 30% heli fuel. That'll give it a good kick in the pants.

On my first one I did it like you guys too. After doing my second one I know what I did wrong: I didn't follow the manual religiously. It specifically says to use card stock to make the engine holes and the firewall locations. Then it says to take the engine out to cut the holes. Then it says to put the engine back on to test fit it. Then you keep fine tuning the hole locations with a dremmel while centering the prop in the front opening. After this is done, I spent a long time lining up the opening for the prop to center it perfectly (for the last time). I also made sure the spinner back plate had about an 1/8 inch of clearance from the front of the cowl. Then I used masking tape to hold it there. Using the card stock firewall locations, I drilled the holes for the screws just under an 1/8th inch behind the leading edge of the firewall. It was perfectly centered. I tell you what though, I hate doing Funtana cowlings. It took me 4 freeken hours of putsing around to finish it. I didn't want to mess it up again so I checked everything 10 times.
