Synergy 90 ARF
 

I just looked at the pictures of the Synergy 90 3D. Well, I actually saw last year, but didn't think much.

Ok. here is the question.
Which one of you is using Asano pipe?
The first row, second from right is the Asano header .
How do you like the Asano pipe? Is it a 90 size or 140 size?

I have been using one for YS 53/63.
I am planning to get one or two of larger size Asano pipes to use with Hatori headers hopefully.
Pipe itself is very good value, but when you include the Asano header, the cost goes up.
What do you think?

Hi Guys,

Looking at the PDF setup document from ZNline, I was intrsted in the speed and torque of the servos. Question is are they being run at 4.8V? I assume they are.

My Synergy 90 3D arrived today!
Everything looks good. Can't wait to get it assembled. The YS 110 I ordered for it is on the way.
One note: There are no instructions of any kind included with this kit. There is the PDF file on ZN's website with a CG and recommended throws. Should not be a problem for experienced builders/flyers and I guess and that's who should be buying this kit.

I heard that thing was a hunk, can I buy yours? hahaha

Mark & Ben,
I have looked and looked and I don't see a cut line on the canopy.
Well, I do see maybe 1" of what might be a cut line. Did your canopies have a cut line? If not, what did you do?

Thanks, Jim

To answer several questions.
 

Pattern Flyer, the Asano pipe is being used by CPLR. He is using the 90 pipe. The 140 pipe would require modifications to the fuselage behind the wing saddle. The Galileo website in Japan has this modification in a picture. I plan on sticking with the Hatori as performance is awesome and it's very simple.

Kris, I'm not sure if CPLR is using 4.8 or 6.0 volts. JP used the new 9550 digital car servos on 6.0 Ni-Mh and they are fast. I'm going to use 9402 and 9201 on 6.0 Ni-Mh. BTW: We routinely use 6.0 volts with the digitals that Futaba recommends as only for 4.8 volts with no problem whatsoever.

Jim, for the canopy. There is no cut line. First trim away the front and back and set it on the airplane. It takes a few trimmings to get it perfect, but it is really easy. Look at the pictures on the web to get an idea of the big picture. Anyway, after trimming away the front and back, trim the sides, however, keep them longer than needed for now. Next round the front and see how it sits. Continue rounding the front until you like the way it sits. Then trim the back parallel to the turtle deck front so it overlaps the turtle deck by about 1/4". Then simply trim your sides so that about 3/8" inch hangs past the cockpit floor for four servo screws.

They're here!!! WOO-HOO
 

Just got the call from Central Hobbies. The Synergy 3D's have arrived. For the chosen few who had the insight to reserve one, they're going out via Airborne Express Ground. Mine will show up Monday morning. I'm so excited, I'll have to wear a bra if I go out in public!

On a lesser note, I inquired about the YS 110. They had talked to the distributor (YS Performance?) yesterday & it looks like late summer at best for this engine. Guess I'll be putting my trusty YS 91 in this plane. Should still perform admirably with this engine. Stay tuned.

P.S. Central also stated that they're expecting a new shipment of YS 91's in a few weeks, which will be their last! Apparently the 91 is being discontinued in favor of the 110. The YS 140 "Sport" (being the replacement?) for the now discontinued 120) will be available before you see the 110. Guess "Power To The People" is YS's new motto.

synergy shipping from central hobbies to california......central being in Montana... 100bucks I was told.....whew, makes that plane delivered about 540bucks. umm. this plane has a nice shape but, what am I missing here...that's way too much for what it is. and that covering job, ? i'll build my own. I just don't understand the hype

YS91 will do fine.
 

Raintown,
We have not yet tached the 110, but given that it is only a bored over 91, it can't be soooooo much more powerful. Given the way the 110 yanked the Synergy around like a yo-yo, the 91 should still be a very respectable powerplant with absolutley full 3D capability. Later in the year, if you like, the 110 will bolt right into place with absolutely no modifications and give you just that much more umph. Of course, I know, as I am the same way, that the more critical flyers will always opt for the highest power to weight ratio in a chosen motor catagory, but don't be at all discouraged from using the 91, it will be great.

I think the big difference between the 91 and the 110 is going to be security. When low and slow and stalled, having the extra few RPMs assist in getting away from mother earth. So put a couple extra meters between terra firma and Syn3D until that comfort zone is there.

The 91 will fly an 8.5 pound airplane with full 3D capability, albiet it's not going to blast out of a hover. This airplane weighs only about 7.2-7.5 pounds. The loss of a pound is a huge difference for the 91. It is by no means a marginal powerplant; actually, it was the powerplant the airplane was originally designed for.

One thing to keep in mind is the CG. When engineered for production, the designer kept in mind that many people would prefer a two stroke motor, namely the OS91. The YS will leave it nose heavy unless the battery is mounted in the rear. We made a square incision below the stab and mounted the battery to the stab. The CG came out perfectly (230mm forward of the TE) with no extra weight, and there is no sacrifice in strength. The battery hatch was simply glued back in and a piece of white Oracover placed over the area. Looks great, balances perfectly, still weighs the same (about 7.4 with the YS110FZ).

After you get it together and fly it, please let us know how she does with a post on the new Syn3D flying report thread.

Thanks,
Mark

Synergy 90 3D construction
 

I am starting construction of my Synergy 90 3D today and hope to get it assembled this week. My YS 110 arrived today. My Hyde soft mount should be here in an hour. I need to order a 2-3/4" spinner, but I think I have everything else I'll need to assemble the plane.

Mark,
I think I understand the engine mounting procedure. The thicker beveled piece of ply is for the right thrust and the thinner one is for the down thrust, correct? Just line up the holes on the pieces of ply with the hole in the firewall and glue them on, correct? Then center the motor mount on these pieces for the correct engine offset, correct? What is the proper distance from the firewall to the engine thrust washer?

What are the parts in this picture for?

Thanks, Jim

Hamm....
 

Looks like a stab joiner and wheel axles......

You sell anything at Perry this weekend? If not, I can help you out a bit by picking up the Synergy from you.......

It was nice meeting you....good luck with the 3D.....and can I please fly it??????????

Pug

Synergy 90 ARF
 

Your right Pug, those are probably wheel axles, but I don't know about a stab joiner. The stab is one piece. You mean to join elevators? Each elevator has it's own servo.

It was nice to meet you at Perry.

Jim

Ah....
 

I guess it would be kind of strange not to have 2 servos on the elevators.....

Noticed how you glossed over me flying your plane......:(

Hopefully we can hook and fly some time this year....

Pug

Correct
 

Jim,
Your description of the thrust pieces was right on. I do not know exactly what my firewall to backplate measurement is. I stand the fuse up on end and rig everything and set it so that the cowl overlaps onto the fuselage by about 10mm. I'll ensure I get some proper measurements to make it easier.

There is indeed a elevator coupler, and the elevators even have pre-drilled holes. Unless you are flying a simple 4 channel and running a lightweight 2-stroke (OS91), toss that piece into your spare parts box. That piece is offered for the most simple set-up. I assume just about everyone is flying at least a simple computer radio capable of mixing two channels to run the elevator. With a YS on the nose, the two servos will assist in getting the CG back. Again, we mounted the Ni-Mh on the stab to get a perfect CG according the CPLRs sheet.

Question for you:

What do you think about the construction of the wing? In particular, these things. One, the way the long dowels key into the spar shear webbing (one end is machined to fit into the fuselage keyholes). Two, those end cut wing bolt seats (nicer than a plywood chunk glued onto the surface). Three, the basic appearence of the wing surface...smooth and even, no ripples, no sheeting sags in the between rib sections.

I think it is as well built as possible. Your opinions are valued.

Mark

Synergy 90 ARF
 

Thanks Mark,
I am impressed with the wing. It seems super strong, yet light, and as you said it is nice and smooth. I can't think of a way to improve on it.
My only concern is the ailerons. They are not very rigid. I know you guys are trying to keep things light but I think these ailerons should have been sheeted to make them more rigid. Also the hard points for mounting the control horns on the ailerons do not go all the way through the surface so the only way to mount the control horns is with wood screws. This does not seem strong enough to me.
The rest of the plane looks great from what I've noticed so far. I'm just not sure about those ailerons.

Jim

Synergy 90 ARF
 

Jim,
The wood screw go into aircraft ply. Not a problem and very strong. The ailerons do feel light, but so far no problems. We lined up the traling edges and sealed the gap with clear Oracover. A friend closed up his gap by recessing the hinge slots and did not worry about the even line at the trailing edge. Either way, although I prefer the even trailing edge. Also, the extra gap sealed with Oracover allows perfectly free movement.

Screw in your horns with the wood screws and tug on them a little bit. How about bolting them onto a spare piece of scrap ply and really tug at them...with pliers. This will give you the confidence needed to fly comfortably (try using a spare horn that you no longer need). Really, when you see how tough it is you will feel great about flying it mounted that way. On our 2m airplanes, we bolt our ZN horns onto ply mounting points using 5mm long screw and they never pull free.

I really look forward to your flight reports.

Hi Mark,

Couple of questions:
- what are those little brass dowels with a rounded end and a groove in the middle? Are those used at the front of the belly pan to hold it in place? If so, why brass???
- What tank did JP use for the YS110. If I remember correctly, it was a Tettra but which one (so I don't have to guess)?

Thanks
Ben

Tank and Pins
 

Hi Ben,
Greeting and salutations. I hope Florida weather is conducive to flying. I am in Germany right now. I brough a Tai-Ji to leave at my girlfriends place. I stopped by the field to fly and in the middle of a warm up flight the wing came off and now I still have no airplane to leave at the girlfriends. Darn. It was a nice practice airplane. It made everything the right degree more difficult for brain practice.

OK, Synergy 90 tank. We used the 400cc Tettra. It fit, but the 400cc MK tank would probably be a better option. The cockpit floor had to be relieved for the bubble on the Tettra.

The brass pins are indeed for the belly pan. Why brass? For that you would have to ask the Czechs. I think it is because they will not wear out. The groove holds the epoxy nicely, locking the pin in place.

Today is my last day in Germany. Time to get back to Belgium and build Enigmas and work too.

Take Care,
Mark

Elevator
 

Hi,

First off all, sorry for my english! I´m from Germany and it´s difficult for me to understand/write the special "RC-expressions"....... :rolleyes:

Just one question about the elevator.
Is it actually necessary to strenght der elevator-section?? Look at the included picture an you know what I mean :)

Synergy 90 ARF
 

Having flown the airplane, I feel the elvevator definately reequires the strengthening. As at times, one maybe doing high stress stunts, and it helps adds to a piece of mind! With such a big elevator, I presume it is always better to be safe! It doesn't add much weight anyhow.

Synergy 90 ARF
 

I don´t know if it´s already been mentioned, but has anyone measured the rpm of the YS 110 and YS 91 with a APC 15x8 ??

Synergy 90 ARF
 

How about using the YS 91 ST? Although it is a two banger heli, I think it would work quite well. I am putting one in one of my projects.

Fuel tank for the Synergy
 

I found that the Hayes Fuel tank Slimline 16Oz (~450cc) will perfectly fit the available space in the Synergy. It is tough enough to resist the internal pressure put by the YS (I used it with a 140 for a while).

I was concerned that the supplied tank (~360cc) might not be enough for the YS110 I'm planning to use.

Just passing the information...

I started the construction yesterday, the feeling is that it will be a joy to build. You know, one of those kits where everything fits in to place, no sanding, and well thought out.

Ben

Synergy 90 ARF
 

I went through my pile of fuel tanks yesterday to find a good fit in this plane and came up with the same one..... the Hayes 16SL.
I was wondering if it would hold up in the pressurized environment of a YS fuel system since it has a press in nipple with an "O" ring on it for the clunk line fitting. Now I know, Ben has answered my question. Thanks Ben.
This tank is a very good fit in this plane and a lot of the other 16 oz tanks I tried would not fit (Dubro, Great Planes, etc.).
One other option might be the 400cc MK tank as Mark suggested, but I did not have one on hand to try.

Jim

Synergy 90 ARF
 

I am having no problems with using the standard tank, with the YS 91AC.
