I am just wondering how a 1.60 will do in a funtana. I have seen this combo at the feild, and it flew awesome. I have no other engine to put in this plane, so I am willing to give a shot. Are there any disadvantages?

that seems like way too much power to me..... but what do I know.

A very experienced flyer at my field has a YS 1.40 in his and it seems like a good match. The 1.60 might be a little heavy though, about 39oz with a light pitts muffler. If you know how to manage the throttle you won't get into trouble over-powering. Add some beefing to the firewall, at least smear some polyurethane glue over all the joints.

I will say after seeing it fly with the 1.40, a 90 or even 100 would not do the plane justice.

I am bidding on a YS 1.10 on ebay, If I win it @ 275, I will wait for that I guess. My concern is not overpowering it, but the weight. Will it fly properly with 36 oz on the nose?

I have a ys 120 in mine, cg is good with no added weight. Plenty of Power to spare.
Came out to 9 lbs 5 oz total.

I have seen a few funtana 90's fly with a saito 100 and I think they are way underpowered.

OS 160 (I have 2 of them on other planes) would need a fuel pump and throttle management.

I had an OS 160, its a lump of lead if you use it on the F90. Lump meaning you will probaby have nose heavy issues. Also, that baby will easily turn an 18x6 prop. I cannot imagine your F90 with the OS ... hope you get lucky on Ebay!!!

Not sure what you mean a 1.00 wont do it justice? A saito 100 pulls the f90 along just fine, hover, torque rolls, rolling circles, anything. Now if your flying at 10,000ft and want the plane to be a speed monster rather than 3D the YS 1.40 is a perfect match.

I guess if you keep it light enough the Saito 100 might work. All the F90's I've seen are 9lbs and over and IMO it's too much plane for a 100. Some guys are putting the 100's on the F40.

I'm not saying the 100 WON'T hover it, but pull-out can't be good at 9lbs+

The F90 is a big plane.

jayselle

Why are they so building them so heavy? They running 4 batteries, 8 servos, 2 fuel tanks, etc? Also keep in mind how light the Saito 100 is, in some cases it is a pound or more ligher than some of those monsters.

The 1.60 is the perfect engine for the funtana if you know how to use the left stick and as far as it being heavy mine is right at 10 pounds with NO extra weight added to the nose to get it to the c.g.specs. I have maybe 20 flights on mine and love it, oh and I don't have a pump on it either and I'm running a Bisson pitts muffler, just use large fuel line all the way from the clunk to the carb.

Mine weighed in at 9.4 lbs. I have the Saito 1.80 in it with a 18x6W APC and it flys great! I did not have to add any weight to it anywhere and have my CG at 7 1/8-7 1/4...

I just happen to have this ST2300 w/Perry pump/carb setup and Slimline muffler laying around waiting for an airplane an low and behold, mamma got me an early X-mas present.
I am going to use a 17x6 wood Zinger for starters. Havn't seen any post of people using this engine but if they can run a Saito 1.80 surely this ST2300 would be just about right. Using a D.Brown 1.20 mount an pinning he firewall and glassing it. Reinforced the aileron rib and hard mount and am going to go with double wire diamond on the stab to keep it from flexing. All up seems to be a well engineered kit. My firewall will need to be pinned and reinforced also. I can see day light between the firewall and box side. I am using a set of Bolly c.f. FAI large gear and with the light weight foam wheels is 1.5 oz lighter then the smaller and more flimsy alum gear and rubber wheels it comes with. These Bolly gear are very forgiving yet spring back every time and they dampen rough terrain very well plus I will be able to use up to an 18" prop with plenty of clearance. Did a mod to the rudder by putting additional ribs in it and used 1/64 play doublers on both sides of the horn mounting area per Eric Hendersons recomendations...his broke righ tat the control horn.

We are flying pattern planes with 1.60's and 1.70's in then on 9.5 to 10lb airframes so why not in this airplane.

I will post some flight reports and photo's as I go.

"The 1.60 is the perfect engine for the funtana "


Just what I need to hear cause I just lost the 110 FZ by $5! I am in the middle of installing the 1.60. I will use an 18-6W prop, and set the engine back 1/4 from the specs. (good ol trick from my drag racing days) This should help with the nose heavy CG. To accomplish this, I had to relocate the remote needle to the firewall. Will this be a problem, other than a delayed response to my high speed needle adjustments? I also pitched the spegetti thin clunk hose in the tank, and increased the to and fro hose size from the tank. Can you guys think of anything else?

Thanks

jayselle

The Funtana 90 will not fly properly without at least 34lbs of thrust.

tIANci

jayselle ... what nonsense are you talking about you cannot use that to power the Funtana 90, what you need is this ...

Rocketdyne's Space Shuttle Main Engine. The maximum equivalent horsepower developed by the three SSMEs is just over 37 million horsepower.

Now we are talking RAW POWER!!!

i bought a ST2300 and used it all of 8 times in my new piece of crap overweight giantscale planes . com sukhoi su-31 before the gear came through the fiberglass for the 3rd time. i am so sick of re glassing this bird. anyway i am going to install it in the funtana 90. i see no reason it wont work. More power is better anyway right. lol i will post my flight results soon

tIANci

More power is not always better. It very much depends on the plane. 3D planes want light wing loading to perform all the nice manouvres. That is why you do not see the pros over powering the 3D planes like your H9 F90. Look at how it performs with a YS110, maybe a YS140 would be more fun but not at the expense of much higher wing loading. Something like the OS160 is about 6 oz heavier than the YS110. In a F90 you don't really need that much more power for full 3D flying ... not just to prop hang at 15% throttle.

Steven7x

Just flew My new F90, with the 1.60, and it is AWESOME. Well actually I gave the sticks to an experienced 3D pilot. This is a great combo. This time I went with the 130 oz servos on te ailerons.

tIANci

Steven - I think you are nuts! Must be able to prop hang at 15% throttle, hehehe ... What sized prop are you using?

Meesh

My Feedback: (135)

I think a 427 Big Block Chevy should be the MINIMUM requirement for this 90 sized plane. After all, you can "never have too much power" and I "know how to use the throttle".

When I get bored with that I'll look at the Viper V-10. Can you just picture the 5000RPM torque rolls with that puppy on it! You won't even be able to see the wings!

Wooo Hoooo!

That would be the Aluminum version big block, right?

Definitely Aluminum, Gotta keep that weight down!

Steven7x

18 x 6W, and it out flys, out hovers, and out 3Ds all other F90 combos Ive seen out there, in case you naysayers are interested. In fact, there was another F90, with the same combo I had...F90, OS 1.60, 18X6, so I guess he must be deranged also. Either that, or we just know how to use the left stick!
