Mark....any news on replacement better canopies?

Simon

if you need spare parts, you should better get in touch with me directly at [email protected] - this only because I am the one in direct contact with the production of the ARF kits from ZN LINE

We indeed have had a few thin canopies, but

a) we cannot make ticker one
b) the problem occured only on a few kits of the last shipment. I suppose that Alpha centuri is somewhere in England (I can't imagine an other country that have Aliens) - so please cotnact me on direct - I will try to help you asap.

Also, what pipes are you using? I will put a 110, but don't think that the extra hassle of a pipe will be worth it.

BTW, having read some RPM figures, it looks like the 110 is similar, if not stronger than the Saito 120.....YOWZA.....
Got my Saito figures from a magazine, and the YS from here.

Robert,
I HAD a pipe and it is really a lot of additional
headaches, and no gain (except weight)
The standard YS 91 FZ muffler is perfect.
The arm is just the right lenght for the muffler to be
outside the cowling where you only need a
small hole for the arm and the muffler sits nicely
entirely outside of the cowl.
And IMHO, the engine works better without
the additional back pressure.
Happy flying
George

im using the ys91 with an hatori pipe,nice and quiet ,the engine runs fine.

Derek,
About the YS 110 It should be obviously lighter than the 91 simply because the only change is the bore! less material mean less weight. The piston has to weight the same for balance!

Concerning the Saîto 100 I'm not sure about the power but the weight is 550g means about 2/3rd of the YS 91! This h. Nishi consideration (Galileo) has a lot of sense for 3D Performances. Think about this plane around or less 3Kg. I saw the flights on the first one in Japan one year ago this prototype was a bit too heavy but the Japaneses skilled pattern guys cried when they saw it flying pattern then 3D. All in one, this well borne plane is just a jewel.

Just my two cents about Price! Every one would like to have a Porche for the price of a Skoda. Any whatch can gives you time but you may like to enjoy a Chronomaster Zenit price # can be 100 times more and you get the time in both case. It is just to know what modelers admit to pay for. I can easily pay twice as much a Chinese made kit and enjoy a Plane that has High Technology and bare spirit of CPLR and ZN Guys, and provides me emotions.

Anyword on when the new ones are in yet Mark?

JP should be on his way to Aachen to pick up 30 kits tonight. I'll be in the shop early tomorrow...I hope I see Syn90 boxes stacked to the ceiling!!!

Mark

Yeah,

go on Mark tell us. Pleeeeeeeeease..............................

Kris

Alvin,

I have sent you a couple of mails about a damaged canopy replacement.
Did you not receive them?

Appologies if you have and a replacement is on the way.

Alvin is on holiday... til the twenty something of this month..

Thanks Arch,

Glad to hear things have gone well with the Capiche launch.

Im in two minds now?? i have a YS110 on order (be here next week) but i know even with the Batt behind the wing i am going to need 3oz of lead on the tail (CPLR advice) so do i use a saito 100??

has anyone got a comparison prop for prop of the YS and the Saito. from what i understand the YS is grossly overpowered and although the saito is less powerful it may be OK. i only want enough power to fly a reasonable F3a pattern and enough thrust to pull out of a torque roll confidently when it all goes wrong!

Dave

im flying mine on a ys91 which is not grossly overpowered but will pull it out off prop hang easy,i think the saito will be enough power but will be marginal,the ys seems to have tourqe and sheer power when put under extreme loads.
mike

how much lead you got on the tail Mike?

You could also put the rudder servo in the tail if you wished. There's a slot in the rear that fits a servo rather nicely, above the elevator servo hole. Just some ply below, and drop the servo in there.

How did the balance come out with the YS 91 on yours Derek?

I hadn't had chance to try it with the servo at the rear yet. It should help the 3D performance a little, I hope.

the boy
ive got about 15 grams at the moment,i know its not much but im gonna go more,does 3d ok parachutes are good flipping from upright to inverted.good blenders too.

cheers Mike, thought one of the yanks might have some data on the saito, i thought they love em that side of the pond!

I got to have a go on one yesterday. It was a bit tired, and had worked hard but was promising nonetheless. Needed up elevator coupling this one for k/e, but to be fair the weather was apalling, and there was not time and feasability to check things like cg, etc. although it felt okay in the Force 5 wind conditions !

Belly pan came away on one flight. It broke through the back end where the cap head holds it down. Dont know if there is any ply doubler on the inside of the belly pan at the back but it might be worth considering. We never found it.... and I hasten to add this happened after a lot of flying and it was a bit fuel soaked, so dont panic about yours if its new... but check for doubler anyway.

I pick mine up in June and cant wait... Must try to get it done for the Jersey Show in July !, and I note the comments here about cg and the rudder servo. Good pointers thanks.

One dissapointment though for such a thoroughbred as this on quick inspection, is that the easy mistake of poor servo positionsing (aileron) and insufficient horn plate area is provided on the surfaces. This stuck out to me cos I got Malc to make changes to the Capiche for this very reason - caused a bit of extra work but worth it in the long run.

What do I mean ?

Ailerons. Well the Servo hole is too close to a rib or at least positioned badly. The result is that the horn plate, which is not long enough in chord (medium MK Horns dont fit cos there is nothing to attach to at the back), is only slightly offset to the servo hole. That means for proper horn mounting, and proper geometry, you have only room for about a 8mm output arm.!! I think it should be positioned to allow an average of 15-20mm.
The result is, that without moving the servo, or cutting the film and adding extra wood to the horn plate, you cant get enough throw and have right-angles on the linkages.

Rudder. There is just enough meat to fit the MK Rudder horns, but you have to put them high up to get that meat and to avoid the elevators on extreme throw. The high up situ causes misalignment of the closed loop slot and the closed loop line.

Sure everything works if you use the MPJet accessories (except aileron geo) but whilst I dont have a problem with these products themselves, I dont think they are entirely suitable for this plane, which is an outstanding model indeed.

But hey, then we come back to the age old issue of appropriately costed accessories including in any kit dont we !

On the cost side, I was going to use one of my old YS 120s (new piston and liner, races etc, so in good nick). It seems people are showing concerns about pushing cg back.

So, do you think the 120 will be a mistake? Im happy it is not too big and all that, and theres enough power, but maybe the weight will be a problem? Any thoughts? Was trying to avoid shelling out on a YS 110, although I do fancy one I must admit !

archie
the 120 will be ausome power to weight ,but there is that cg factor,you will most deffinitly have to add weight to tail,i dont think there is much in weight differnce between 120 and 110,and also the 91,i would weigh mine but the capiche 120 is housing it at moment,give it a go,i dont think anyones flown it yet with 120.

My problems so far.
I just noticed the ailreon horn position problem. I have fricken HUGE Dubro 3D horns, that are too far out. What did y'all do?

I don't like that Horns too much. I have MK ones for the rudder, I'll use the stock ones on elevator, but what do I do about the ailerons? I am not going to shelll out €18 or so for the Zn jobbies. What is everyone else using?

what did you all use to cover the hinge gap? The only stuff I have here is some white, red, and yellow solarfilm, and some black profilm.

How did you all do the ariel routing?

Top plane so far, nice one. The canopy IMO is fine.

hi Guys

Just been looking at my aircraft. I see the Ailerons horn position problem. I recon that MK rudder horns part no 0812 will work. I am using Hitec 8925's and I will use the ali servo arms. With these horns I can fit them into the tri piece on the aileron with no problem and still get the required 3D deflection. I woul have prefured longer turning moment though. Looks like the geometry could be out though, if it is then I will change the plasic horn end for a longer one. The same horns look to work out well for the elevator. They will not work on the rudder though, they don't get the clearance from the elevator, at least on the closed loop set up. I will have to think about this one.

What are you guys doing about reinforcing the UC area?

Kris

I epoxied some tri stock on three sides of the U/C area.
