    Forgot to mention I am using 15% omega 2-stroke fuel!

    Thanks,

    Status: offline     		Is anyone having thrust issues with theirs? In vertical uplines and prop hangs, mine wants to turn to the left violently... i can correct it in vertical uplines using rudder, but in prop hangs the rudder doesn't have enough authority to correct it before it falls over. I checked my thrust angle, and I have about 4 degrees of right thrust, but it's still kicking to the left. Running a saito 72. Any help would be great.

    Thanks for the additional info. That all sounds good. Your engine should still pick up some substantial gains as you get some more time on it, but it should be pulling well at this point.

    I think mine makes it's debut at the field tomorrow. I'll be putting up pictures and specs on it after the flight. It's a bit of an experiment, but I think it should work out pretty well.

    Status: offline     		Just a bit of warning... replace the elevator and rudder pushrods. I lost my funtana today, and although I'm not 100% certain, I think it was the 2/56 pushrods combined witht the plastic clevis flexing and couldn't pull the plane out of a dive. went straight in and is now nothing more then scrap balsa.

    On a good note though, I also baught a ohio models sukohi the cowel is rediculus, it's pretty much a 5 gallon paint bucket.

    Status: offline     		Well I just finished my wing dowel fix... 11/32" thinwalled brass tubing from your local hs is a perfect fit over the dowels so I cut two pieces and epoxied them to my dowels right up to the shoulder of my bevel on the edge. Then I took a piece of 1/8" light ply and made some doublers in the bulkhead around the wing dowel holes and drilled them through with the same size as the originals. The holes are too small for the brass tubed dowels so they need to be augered out, I chose to do this with a slightly smaller drill bit wraped in some 180 grit sticky backed sand paper as you can make them PERFECT this way, plus it is a much nicer hole than a drill bit makes. I enlarged the holes only in the direction facing the canopy and the sides, leaving the bottom of the original hole where it was, this made for a tighter wing to fuse mating. Then soaked inside the holes with thin CA and re-touched them up with the paper and they are beautiful, wing is a pressed fit to get the dowels in and I pull closed about a 1/16" gap with the wing bolt at the trailing edge to fuse mating edges which makes the wing TIGHT, no slop at all and never should be. Flying it tonight so should know how it affects the flight characteristics soon.

    B.T.W. - Is it just mine or have any of you guys had your carbon tail reinforcements tearing out on one end or the other?? Maybe I just have to be nicer to Mr.Airplane in the air? ROFL

    Status: offline     		Just a warning, there is another thread about the rods coming loose. We had a guy in our club lose both stabs and of course the plane after they came loose. Both stabs folded up, right at the fuse.

    Status: offline     		OK, I'm starting to like the plane a bit more now that I have a few more flights on it. In fact, Saturday night, I flew it at a night fly.

    Set Up: Irvine 53 w/ Tower muffler, 4721's in the wing, 9402 on the rudder, 9203 on the elevator, CF gear, lighter foam wheels, Tru Turn spinner & tail wheel, 6 volt 1100 mill pack, CF rods and ball joints on all surfaces, aluminum servo horns, 5 lbs 8 ozs.

    On the stabs breaking: I used Dave Brown carbon fiber, that I laminate onto the bottom of the horizontal stab at the trailing edge. I have used this method on several planes and have NEVER had one break. I have broken many with flying wires.

    I did not add any additional right thrust to the motor and I have no vertical issues. I am using a 2 stroke only swinging a 12' prop, however if you are using a 4 stroker swinging a 14" prop, you may want to add a washer behind the mount and add some right to it.

    I moved the CG back some, 7 inch's back. It flat spins better, hovers better, knife edges a little better and does everything just a little faster. I have the battery pack located right on the CG and the receiver on the other side of the middle bulkhead. So no additional weight was added.

    Mods: I double beveled the horizontal and vertical stabs to get more throw. Elevator high rate is 70 degrees and low is 45. On high rate it will do a waterfall, however you have to work the throttle. If I use spoileron it will just flip over and over and over and over. It does a great knife edge spin. The rudder will now SLAP the elevator half's at high rate. I used 1 1/4" servo arms. To do this, you need to swap sides on the elevator and rudder servos, so you don't get a weird angle on your control rod. This bird does a great Harrier and spoilerons are not needed.


    The Funtana does not seem to like flying very slow. I was thinking mine was heavy, however with the Funtana weight thread, I am right on par with others.

    The Funtana is not as forgiving as the Flip or UCD or a Profile. This bird is not for the faint at heart and it will keep you thumbs, eyes and brain on FULL alert.

    Status: offline     		Ok, finally here are a couple pics of my wing dowel fix I mentioned in an earlier reply to this thread... the mounting holes are doubled and the dowels are "brassed".

    Status: offline     		Hi YNOT,

    You have me confused with your last post. You said you double-beveled horizontal and vertical surfaces. I can understand the horizontal, but the vertical will hit the elevator easily with the stock single bevel, so I was wondering if you re-cut your elevators to allow for more rudder throw?

    >>This bird is not for the faint at heart and it will keep you thumbs, eyes and brain on FULL alert.

    Also, my guess is that your impression of the plane as being hard to fly is a result of your control throws, not the weight of the plane, or any inherant characteristics. I believe if you set your throws on low rates to the suggested stock settings and fly the plane with these settings, except when performing specific maneuvers requiring the high throws, you will find the plane to be quite forgiving and very easy and relaxing to fly. On low rates my plane is docile and is very smooth and easy to control for all "standard" aerobatic maneuvers, including slow flight and landing. On high rates, which are about the same or a little more than you have your low rates set to, it becomes very sensitive to control input, even with 80% expo....which is what I would expect.

    Status: offline     		Hi Bill,

    Yea, I double bevel the rudder also, in looking back I did not need to. It slaps the elevators half's pretty hard. It was not needed.

    I posted on another thread about adding 1/2 ouch of weight on the left wingtip. It stopped the right wing dropping in a hard pull. Now it does a great wall and parachute.

    I have several more flights on it now and have gotten it dialed in. I am running a bunch of expo on my low rate and only use the high rate for a few extreme tricks. It will do some very cool things on high rate.

    Status: offline     		Hi Tony,

    Thanks for the answers. With the many Funtana threads it is hard to read everything, and also to remember where you posted what. I'm glad you got your lateral balance issues fixed. I was lucky with mine and it was balanced and stable in walls from the get go.

    >>It will do some very cool things on high rate.

    I bet it will. If I keep this long enough I'll probably go back and do the double bevel just to see the difference.

    Status: offline     		I finally got mine back into the air on Sunday. I did exactly the same mod on the wing dowels and dowel bulkhead as Abraxxas, and the wing is snug and has no more movement. I also added wing wires on the horizontal and vertical stabs just like the SIG Something Extra. These, I am sure will keep the stab from folding even with the carbon rods like some others have done. I am about to lean out the high end of my Saito as I now have about 14 flights in and think the engine is probably broken in now. I will be at the field tomorrow after work, so I should find out then.

    Status: offline     		I just flew mine over the weekend it a fun plane but it wasn't what i expected. I think that it it built to light which makes it weak in some areas. I almost put my finger through the underneath part of the firewall and a rib in the wing was broken which i had to fix. plus mine pushes hard to the gear in a knife edge it was fun but i think there is to much hype over this airplane, i have way more fun with my h9 aresti. I'm not bashing the funtana but i just expected a little more.
