GREETINGS MARK, SEEING HOW THE DZ IS ONLY 5 OZ. DIFFERENCE IN WIEGHT, IS THERE ENOUGH ROOM IN THE COWL FOR A DZ? WOULD THERE BE ENOUGH PROP CLEARANCE FOR FOR A 17 - 18 PROP, AND IF NOT WHAT SIZE WHEELS COULD BE USED FOR CLEARANCE? THANKS!

Earl,
It would not nestle comfortably inside the cowling. Also, the 1.10 is nicely overpowering this airplane. I believe that putting a DZ inside of this 7.5 pound airplane might be dangerous for the airframe. I would fear for catastrophic flutter.

I have see how you did cut out the engine cowl. I have to inform you that this is not enough. You will have to make more cuts. We have been flying the plane with the YS91 recently and have had a few "overheating" problems.

To Huang - we did not do an airfoil stab only because it do not bring anything to the flight enveloppe and is much more expensive to produce.

If you do not like the design, you can vote for the ARC version of the kit. Much cheaper than the price for the ARF one.

WHAT WAS THE FINISHED WIEGHT IN POUNDS & OUNCES? DID THE 91 PROVIDE ENOUGH POWER TO BLAST OUT OF HOVERS?
THANKS!

Earl

the Synergy we fly (equipped with y YS91) ends up including the hatori pipe and Manifold (yes they fit under the belly pan) at a little less than 3200 Gr (a pound is 453,59 Grams)

Getting vertically out of a hoover was a piece of cake. For the pattern pilots we made 7 vertical turns and then continued vertically out of sight.

Hi Alvin,

Many thanks for your updates! You guys are really good!
How about hardmounting the YS-110? Are there any options to softmount the engine?

in my Synergy I used D-Lock M4 - very easy to use, do not require space, cheap and quite effective.

To have an idea what I am talking about have a look at (its in german but images are universal):

Hi again,
For anybody who needs information on control throws, CG, recommended expo, Christophe's set-up is now downloadable from the ZNLine website. Go to the Synergy page and towards the bottom you will see a PDF file. That contains CPLR's detailed set-up information including his throttle curve (Futaba 9Z).

Thanks,
Mark

I picked up my Synergy 90 at ZN's workshop last week during a business trip in Paris. Good occasion to have lunch with the whole ZN gang (Nathalie, Pascal, JP and Mark).

Getting a kit back on a plane as a luggage is always risky but so far, I've been lucky. The box made it in one piece but one side was bumped inside (like a heavy piece was placed on top) and the other was perforated in 2 places (10 inches long but narrow holes through the cardboard). I was afraid to see some damage inside but everything was OK, without a scratch, thanks to the intelligent packaging design.

I am really impressed with this plane. The manufacturing is perfect and I don't know what could be done to improve the quality. I have a couple of short project to finish before I start working on it, but it is tough to resist!!

As I said, I'll bring the kit to the JR IMAC Challenge if people want to see it. And no.... it's not for sale!

Ben

I took out my trusty Madness to loosen up my frozen thumbs and JP took out his new Syn903D that I have worked on for a couple of weeks.

The setup is:

YS110FZ
Futaba 9550 servos on ailerons, elevators, rudder and a 3102 mini on throttle.
Hatori pipe and header
880mah Ni-Mh

All throws were done per CPLR's setup tips as given on the PDF file I posted about two posts before this one.

In a word, Omigod. Fabulous. Monstrous. Wow. Incredible. Awesome. All that and a bag of chips.

First of all, the motor pulls this thing skywards like a rocket. For those wondering, the YS91 will be fine. The 110 is outrageous. After about a minutes worth of running on the ground, we took it into the air. First flight was made without bellypan to allow extra cooling.

The first flight started off with a short takeoff run, wheels up, pulledhrottle to idle, hit the verge of a stall, then firewalled it and rolled upwards about 200 feet at perhaps 2-2.5 rolls per second. No better way to test fly, is there???

Knife edge is effortless, and I do mean effortless. JP pulled it around and did the prettiest knife-edge slip almost to the deck, gave a little throttle and she just soared on by on the high alpha knife at about 20mph. Next pass was from upwind, and just past center he pulled a medium wall into a series of quick torque rolls. This thing torque rolls easier than anyhing I have seen in it's category. He did not try any stationary hovering, but I can see that that will be easy too. Tail slide, piece of cake. Stall turns...more rudder than you even imagine. I can't wait to get mine together an try the famed pinwheel (an often talk about manuever but I have only seen it done once, and that was Steve Stricker during the 98' TOC). Knife edge loops, and another, and another, and another. He did four in a row, so predictable that the fourth ended only about 10 feet off of the ground, and the wings where absolutely perpendicular to the ground. Although it was pertty windy, I did not really see any need to start playing with aileron differential. The rolls were nicely axial left and right (we did fill the aileron gaps with clear Oracover). After the big manuevers, he settled into some elevators, harrier rolls, a little precision stuff, some really fine looking FAI style spins. This thing 3Ds on rails.

Respected flyers and competitors, in my best and respectful words of advice (knowing the company I share in this forum especially), be patient, save the extra few bucks that this runs over some Chinese mass produced airplane, pass up some of the impulse spending, and place your order for this thing. The waiting list right now (it will not get shorter in the forseable future) is probably about 90 or 100 days after making a deposit. This is not any kind of advertising hype. Nobody is going to all of a sudden crank up the assembly lines and make a fortune by selling 1000 copies per month. They will be produced only in numbers that will allow absolute attention to detail. But if you wait and get one of these, believe me, the smile on you face as you rip through the most complex of 3D and precision manuevers will last a heck of a lot longer than the amount of time you waited to get the airplane. I place great confidence in saying that you will not get a better ARF airplane in this catagory until you climb into the realm of Majestics and the genre that follwed in it's footsteps for lots more money than the Synergy 90 3D costs.

Oh, mine arrived today!!! That would make it about 90 days.


I'm also going to splurge for the Camcorder. This airplane has got to have some videos posted onto the web.

Ben, you are going to make a splash at the JR challenge with it.

Enjoy,
Mark

Mark,
Can you tell us how much stronger the YS 110 is compared to YS 91AC/FZ?
Prop size, fuel, rpm would be great.

I am still waiting for one, but not yet available in US.
Thanks,

They are going to love your wife and medical science will owe you greatly for your son. I remember when he arrived, how excited you were. Med science probably feels the same way LOL!!!

Anyway, this is me and JP hanging out in Havay, where the wind always blows but the flying is the best.

Mark,
good to hear that everything went fine, can't wait to get mine started now!

Boy, do that weather in Belgium look cold from here in Florida! ;>)
Quick questions, what tank size did you use with the 110? Was that an APC 15x8 that you used?

Interestingly,
I was talking to Phil Williams from Probuild a while ago about the Synergy 90 3D and whether i should by one from him and he told me to go for the Exclusiv Modellbeau Funtana instead. He said that the Funtana was 'a much better model' than the Synergy 90 3D for value for money and especially the flying. Interestingly, he was not saying this to get more profit out of a sale as some people might think. The Funtana is cheaper!
Plus its also much bigger than the Synergy but then again the Synergy is prebuilt whereas the Funtana is a kit, so that may explain some of the price difference.
Does anyone agree with this? I certainly do, but the Synergy also looks superb.
For me though, the Funtana is the Better plane, even though i absolutely love knife edge flying which the Synergy 90 is a bit better at. Because the Funtana is fairly near scale and has a realistic look I could fly it at scale meets . It also looks real in the air which i like because you can try some scale aerobatics whith a plane that doesn't look out of place .

I guess that qualifies me to give my two cents.

The Funtana is a great airplane. It 3Ds really good. But it does not do knife edge flying anywhere near what the Synergy can do. Maybe when Sebastiano flies it, but not in my hands. The Synergy does knife edge loops around the Funtana.

Although I really like the Funtana, I will not pull as hard a wall with it as I will with the Synergy. I don't quite have the faith in the wings as I do with the Synergy.

The Funtana was a winter's project. The Synergy was a weekend project.

The Synergy wound up costing about $1200.00 with digital servos and YS91.

The Funata was closer to $2000.00 finished up.

The Synergy will 3D wonderfully, fly AA, and then go to a weekend pattern contest and be really competative.

The Funtana will 3D wonderfully.

At this time I still have not enough stick time on the Synergy, but I can tell you this, if they every produce a 2meter verion of the Synergy in a 3D format, it will be the best, price no issue.

To say that the Funtana is "a much better model" than the Synergy is a meaningless statement at best, especially when talking bang for the buck. Basically, one is comparing apples to oranges here.

Anyway, lets not use this thread to start a Funtana/Synergy argument. Trying building and flying both of them like I have and then tell me how YOU feel about the differences between the two.

Hi Cranston, hello Kris,
Hope all is well with you Kris. Yeah, I am keeping my hair short.

Cranston, thanks for your typically straight forward comparison.

Since Luke tossed the subject out here, I am authorized to say that JP Zardini would like to sell his Funtana. I did lots of work on that Funtana and it is top built. OS1.60FI, 9151 servos all around, Hatori pipe and header, glass pipe tunnel, awesome covering job, thank you very much!!!

JP put a few flights on it before the Belgian season ended, but he prefers flying the Synergy 3D for the knife edge capability. He feels kind of like you do Cranston. The Funtana is a really nice airplane, but...

If anyone is interested in a flawlessly built Funtana, and I do mean flawless, PM me. RTF 3300.00 Euro plus shipping.

Sorry CantonSnord,
Didn't mean to offend you.I get your point,and obviously you are very qualified to comment on this,but those were not my words, the were Phil William's. He is the most well known f3A retailer in the UK , and he seems to know his apples from his oranges too.He builds models for many of the top flyers (including mr YS!), and sells both the Synergy and the Funtana, so he has a lot of experience with both of the designs too, and i obviously believe him, rather than some guy i have never met over the internet.(not that i am saying that in any way to discredit you,or suggesting that you are lying, or anything childish like that)
$2000 dollars is a lot to kit out a Funtana though.My estimate with a Moki 180, isomount, pitts silencer, tank c/w smoke system,pro film covering, 8 channel reciever and seven 10kg servos is £786
opps sorry forgot propeller and glow plug .= £800 which if you work out into dollars is around $1200.Thats a lot cheaper than yours.Is r/c stuff more expensive in belgium?
I am not that interested in hardcore F3A anyway though,3D is much better but i enjoy four+8 point rolls, rolling circles and loops and figure eights, so the Funtana is probably the Better plane for me.I also have a lot more confidence in an airframe that dad and i have built ourselves,(it also feels more special, and unique) and i don't want to add to te demoralising flood of ARTFs at the club field. 99percent of Models appearing at the field are so boring and unoriginal nowadays.
Anyway thanks for the reply
Luke

Hey just thinking, could extend the height of the Funtana fuz up and inch or two!That would then knife edge just as well!

I'have mine !!!!!!!!!!!!!!!!

Now I can say that it's a perfect RTF
Yesterday was the first test-fly and incredible ( good plane - good pilot ! )
I have seen the JP Funtana and it was great but it seems that the synergy with YS-110 was more more and more top near the funtana.
Sorry but I must go to the workshop because the building of the Synergy is waiting for me...

Ben,
Sorry about not answering that prop question.

It's an APC 15-8. Fuel is CoolPower 30%. The tank was a Tettra 400cc. The cockpit required a relief hole to be cut for the large oval bubble on the tank to fit into. I then made a frame 1.5mm thick and capped that with a piece of 1.5 which I Oracovered with white. When it was done, it was not noticable after the canopy was back on.

I think there is plenty of flight time. One will only run this combo full throttle when rocketing skywards. Even knife edge loops did not require full throttle going up.

JP was really throttling this bad boy to make his torque rolls and the thing kept on bouncing up and down like a hypeactive yo-yo.

By the way, to boost JPs ego (like he really needs that), I tell you, after the winter and then watching him fly last weekend, I forget how truly a great pilot he really is. How long has he been going to the World Championships? Ben you would know better than I would. It's over twenty years I think. It's fun watching him learn new flying styles because he has such incredible control over the airplane.

Anyway, on the tank thing, I think a Hayes Slimline or an MK tank would fit without hacking into the cockpit floor. I'm sure that the tank in the picture of CPLRs airplane is an MK.

Wow the Synergy 3D sounds great! Mark and Alvin, thanks so much for your updates. I enjoyed reading them and learned a lot from you guys.

I personally think the 90-class AA airplanes will be a big hit. Many flyers in Asia are modifying Japanese wide-body kits like the Beat-On 90 with 3D surfaces. Many ARFs are now available - there was the G-Trick, Stream 90 Hi-Perf and now the Synergy.

I had the G-Trick which was too heavy (3950g) for good 3D. The Synergy should be much better. How much did your complete models weigh? I also have one question regarding the wing mounting - it looks like you had to take the belly pan off everytime you mount the wing? And how is the pipe mounted?

I know we have one Synergy 90 3D in Taiwan, a guy bought it from Japan half a year ago. I'm still trying to convince him to sell. Is ZN planning to offer a 140 composite version of the Synergy 3D? That would be cool!

Matt
