I had my timer switch set at 12' with the 140 and the 16Oz tank. That would give me the time for a couple turn around on idle if the runway was taken.

The 16Oz is actually 473.17ml, which is oversized for the 110 I think. The 400cc tettra would be perfect but hey, I can always put less fuel in there if I want to !!!

About the horns, I am concerned that they are too small and not adapted to the size of the airplane. If I remember correctly, they are the same as for the Madness. I can see that JP replaced them with some MK on the elevator and ZN aluminum on the ailerons. I'll do the same.

Jim, you raised a question in my head about soft mount or not soft mount. Derek, do you use one on yours?

Ben

Ben,
I'll post some pics of my engine installation with the Hyde soft mount. Maybe that will help you with your decision.

Jim

Here's another pic.

Jim

And one more.

Jim

Mark,
You've asked for feedback so I'll tell you about one more minor improvement that could be done in my opinion.
My canopy is very thin, almost paper thin and I don't expect it to hold up well in the long run. I think it will start to crack around the screws in a short amount of time. I don't know if I got a bad one or if they are all like this, but they need to be thicker in my opinion.

Thanks, Jim

Jim, nice pictures, thanks.
Looks like it moves the engine forward quite a bit (the thickness of the rubber really). Did you have enough cowling length?

I'd like to move the engine back as much as possible to minimize the nose heavy factor. I'm still scratching my head on this one. I don't plan to use a pipe, just the standard muffler. I might want to use some beam engine mount so there will be no interference with the engine chamber. I've got work to do before getting there though, I'll do the engine towards the end!

I just received the 5 servos I plan to use, Hitec digital 5925 - 9.2Kgs(128Oz) of torque and 0.08s under 6V. Those are my first Hitec digital, at least they look good on paper, we'll see on the bench and in the air!

Ben

Ben,
My cowl fits over the fuse about 3/8".

Jim

Jim,
While the canopy does seem thin, it is no thinner than the one on my Madnesses. I can tell you honestly that they have held up perfectly throughout the useful life of the airplane (airplanes as light as the Madness, flown like I fly them, have a lifespan of about 500 flights or so; I get very aggresive).

I think you should be OK, especially soft mounting your motor and the extra screws.

That said, I have mentioned this to the chief for future reference if any problems do manifest thelselves.

On another note, the local weather in Belgium is rain, rain, rain, rain, rain, rain, and a little bit more rain. But next week is Sinsheim, the European version of Toledo. JP and I will voyage south for airplanes and brastwurst.

Mark

Jim,

Only two screws with lock nuts for engine mounting?
Are you using Hyde mount type A that does not require nose ring?
Also, which pipe are you going to use with that Hatori header?

I wish somebody try with 91SX or 91ST heli engines.
It will be a long time until I can get my hands on the Synergy 3D.

Hi Ihncheol,
I will use 4 screws to mount the engine. I just have two in for now during set-up. It is a Hyde type "A" mount that does not require a nose ring.
I am using the Hatori #580 header with the Hatori #675 pipe.

Here is a pic of my set-up inside the fuse.

Jim

Here's a pic showing how nice the Hayes 16SL tank fits.

Jim

Here's a pic of the compartment behind the engine.
I used a piece of carbon fiber plate behind the firewall to help stiffen it up a little.

Jim

Here's a pic of the YS 110 installation from the front of the plane. The engine fits completely inside the cowl.

Jim

Jim,
It looks to me like you will be flying this weekend. Thigs are looking really good. So good ideas on mounting things in.

Mark

My Synergy arrived on wednesday, it looks really nice. I am waiting for a pipe etc. from weston uk so I can put my os 91 in.

On the PDF file showing cplr's settings it says he uses 95% exponential on aileron fast rate, and 80% on elevator, why does he use so much?

Thomas David

HELLO MARK!
I NOTICE THAT THE AILERON SERVO IS PLACED MORE INBOARD RATHER THAN THE MIDDLE OF THE WING IN MY KIT. IS THIS A MISTAKE. FROM A MECHANICAL POINT OF VIEW ISN'T IT BETTER TO HAVE IT IN THE MIDDLE?

There are a few reasons for this.

1. The wing is thicker and holds a servo better more inboard.

2. The airleron is at it's widest there, the higher point of aerodynamic resistance.

3. Rolling inertia is reduced by having the sero weight as far inboard as possible.

There are no problems that we have noted with the location. We did seal the gaps and our linkage with MK hardware (our preference) is absolutely solid. We have had no negative reports from anyone having any problems.

Thanks,
Mark

That canopy is so thin in places, must be a production problem. A days strong sunshine and I reckon it will be well out of shape.

HELLO MARK. THE QUALITY OF MY KIT IS EXCELLENT, BUT I TOO HAVE DEEP CONCERNS ABOUT THE CANOPY BEING ABLE TO HOLD UP IN THE HOT GEORGIA SUN.

MARK WOULD YOU PL;EASE ADDRESS THIS WITH ZNLINE AND SEE IF THEY COULD THICKEN IT AND SEND US A REPLACEMENT?

If I can get a plug made locally, then we can form replacements here in the shop from a sturdier material. I will speak with JP on this issue tonight.

Living in Belgium, I really forget how the sun can shine. I had totally forgottn that it was possible to get more than three nice days in a row until my two months in South Carolina last October and November. Day after day of beautiful blue skys...wonderful.

OK, I'll raise the issue.

Mark

THANKS MARK FOR YOUR RESPONSE. EXCELLENT PRODUCT AND EXCELLENT PRODUCT SUPPORT TO MATCH!

Hello

I've been away quite a long time from the thread. However in order to give answers to a few questions :

horns - the horns are only too small when it come to the ailerons. Therefor, we have decided in the next kits to include a "special" made metal horn for the ailerons.
A few kits have already more than 100 flight over here in Germany. not a failure, not a problem with the horns. Naturally it is not forbitten to install High class, no need stuff

canopy - we do agree the canopy is a little thin. Therefor we will proceed with a modification in the near future. The idea behind the thin canopy was to keep weight down.

If there is any other question about the Synergy 90 or any improvment we can do in the future 8sorry for the ones who already have a kit) just make a little mail

Weston pipe - the weston pipe in on its way. Alan Greenfield just received two kits to fix everything corectly. As I heard today, the new pipe will be a marvell (unfortunally will have the price of this stone too)

Little brass pieces - these parts are indeed to fix the belly pant to the front of the fusleage. They are made out of brass because ...they were existing (we use it on a lot of sailplanes to align the outer wing panels)

Strenghtening - up to now, we do not feel to have to do it. We know that we had a few problems on the start with the Madness, but we have learned our lesson.

Best regards
Alvin Braeckman

Whats this, a Synergy 3D 140????

I am from Singapore, near the equator, and have had no problems with the canopy under the sun. Just two holes punched on the canopy floor, and that's it. No problems.

Greetings, do you think the tail braces are a necessity for high G 3d flight?
