Hi Andreas

I am also assembling an Integral. It is a great winter activity.

You are right, F9650 is a bit bigger, than the place.
I usually use F 3150 at elevator(because of less slope), but it is too slim here so I have changed to F9650.
I had to refashion both elevator and servo, but it sits well now.
Here are some pics for your convenience:

Hi
I have made this. Look at pictures. Is not quite ready.

@All
Please can someone tell me why the depron in the fuselage is curved. I have seen this is in every Integral the same.

I used Digital Hitec servos for elevator control in my first Integral they fit fine. In the second integral I didn't use servos in the Stab. I placed a single servo in the fuse just behind the fuel tank and used a dual pushrod system. The airplane balances much better that way.

Because someone has glued it in the wrong place perhaps?

I would guess that its inclusion in the Integral is a follow-on from the Impact, with its well-documented problems with the fus , before the "Crutch Fix".

I wouldn't worry,myself---the glass/balsa/glass sandwich of the Integral fuselage probably doesn't need the crutch anyway----I don't think there have been problems with that sandwich in things with the same construction(eg Angel's Shadow, Abbra, Leviosa,&c.)

HI
Yesterday I measured my wings. Only the wings. Not the difference betwenn Elev. and Wing. It has me interested. Is there a difference between the left and the right wing.
YES, the wings have 1/4 degree difference. (Measured and calculated). The setting angle difference is 1/4 degrees between Elevator and wings, and I think the difference between the wing is to much. I will not always grumble, but it annoys me again. That probably means working on the weekend. The weather is too bad to fly. So I go into the plant room (basement).
Would it not be better to assemble an Wing adjuster. My opinion is there a wing adjustment from the factory to install. Then you could also make the aileron to zero. This is only my opinion. Criticism is good if it is positive.
Have a nice day.

No doubt about it Andreas, wing adjusters are nice to have, I fitted them on both my Impacts but I haven't bothered on my Integral. My advice would be to fly it before you do anything. You will be sick if you spend the time (and weight) fitting adjusters and then end up with the wing in the same position as it is now once you fly it!

I wonder how the integral would fly with the new fg-36 saito gas 4 stroke w/ 3.5 hp and a weight of 46 oz plus muffler, ignition and mount totals 64 oz. I would imagine tons of torque and reliability. But with a total weight of 12-13 lbs and 3.5 hp, would that be enough to hover and pull out well?

Hi,

I`m afraid it would be hard to get it within the weight limit ... besides; the power/weight ratio would be critical ...

YS is really a perfct 4-stroke route to go, but if i could wish some change`s ; it would be nice to try a " YS 200 PRESSURIZED" like the old ones ...

Hello,

Well I finally finished my Integral and thought I would share a few photos of it. The completed weight of the airframe less battery is 3837 grams, so I have room for approx. 1160 grams of battery before going over the weight limit.

The setup is:

Motor: Plettenberg Xtra 30-10 EVO
ESC: Schulze future-32.80KA
Prop: APC-e 20x15
RX: Futaba R-5014 DPS G3
RX switch: PowerBox Digi-Switch
RX-battery: Kokam 620mAh, 7,4V LiPo
Rudder servo: Futaba S-9151
Elevator servos: Futaba S-9650
Aileron servos: Futaba S-9550
Battery: TP 5300 ProLite

Jason Shulman flying F09 with Integral. Great skills, place and part of the day.

Friends,

I'm kinda thinking about getting an Integral. Choices are 1, Shinden (though unavailable right now) 2, Integral, 3 Otop......... thoughts?? advise, insight??

Hi
Morten, you can save a lot by buying a spinner from Philippe Marquet, they are really lightweigth and excellent quality. Send him a request on : [email protected]
Ola

Hi there,

What prop do you use on YS-170 DZ and Integral? I have currently available an ΑPC 17x12 and a Mejslik 18x10. Which one would you recommend for break in during first flights? Do you use an air restrictor and what is its main purpose really? On my YS engines I always use the Tetra air filter, is that a common practice? Also the std Tetra 580cc tank what flight duration will give me for such engine?

A final question on the spinner, I need a spinner for Integral but I think the final choice will depend on CG etc. I would like to get a TruTurn to be honest but noticed that top guys such as Ola and Matt use the one by Phillipe Marquet. would you use a std plastic spinner by Great Planes with metal backplate (this is similar to MK) with such an engine?

Thanks in advance,
Nikos

A friend recently completed his Comp-ARF Integral, and with an OS140RX it was nose heavy, even with elevator servos in the stab and receiver and battery at the rear of the canopy (ZN may be different).

Based on this, I would suggest a light spinner for sure.

Jeff

I had to add lead to the firewall of mine to make it balance where I feel comfortable.

OS 1.40 Hyde mount Mueller header and Aeroslave pipe. Stab mounted Servos

185 mm back from the leading edge.

Carl

Hi to all
Please, can anyone help me.
I think the problem, I do not have alone. It is a common Problem.
I have made any fotos to show the Problem.
Foto 1 is the detail of the Balsa block. (is from manual). It shows the two holes and the center of the 30mm Balsa block.
Foto 2 shows the detail between the Servo arm and the ruder horn. The ruler shows the correct position of the ruderhorn. But there is no balsa block. only air in the inside. Foto 3 shows the difference 23 mm. Is this a joke fron composite. On Foto 4 shows the detail when I should install the ruderhorn. This is absolutly false. This is shi.....
Nobody make a ruderhorn of 30 - 35 mm. This is absolut false. My only idea is Dremel or Proxxon. Have anyone a Tipp for me. What can I do. And have anyone the E-Mail from Mr. Composite (Andreas Gietz).
Never with me. I hope I will see Mr. Zardini at Italy.
I'm angry, really angry.

You didnt have to put the horn in the centre of the balsa block, if you put it near the inside edge its fine.

Why are you showing the centre hole of the servo horn as a reference point, surely taking you measurements from the outer hole would cause less of a headache?

Also what your pictures are showing is not a rudder horn but a aileron i believe.

You could use a longer servo arm as Jason Shulman did, have a look at post number 83

Good luck.


As for getting help from Comp ARF or JP Zardini....My chin cowl was damaged upon arrival and despite many promises from JP Zardini, 4 months on I still have no replacement and Comp ARF didnt even answer my e-mails.

But heh...theres plenty of other companies that produce better quality planes and customer service...so they wont be getting my business again!

Great . . I hope mine is like yours. I am going to fit my well sorted OS160FX set up and as it's heavier, I was fearing the worst.

Sounds like there is BIG variation in the build up of these things

JB

Jeff,

If you are going to use the OS160FX, try to keep the front section as light as you can, I had to move the receiver battery pack as far back as I can reach to get the CG in ball park, but still has to add some weight in the tail later.

Kevin

I have'nt installed the aileron horns as yet.....will there be a resolution problem using the extremely long servo arms needed?

Colin

Hello i just finished my INTEGRAL and make a couple of flights.

All up weight 4550gr, CG 195mm from the leading edge.

Well done Harris-G, looks sensational!! Tell us all about your setup, would love to hear about it.
I'm putting together a CARF scheme one at the moment which is going to be electric. Sure looking forward to it being in the air.
All the best, Simon

Thanks Simon, my setup.

O.S 140RX with Hatori 915 header and pipe
Hyde ARI mount with CH nose ring
Futaba 9650 servos on elevator and throttle
JR 9411sa on aileron, 8411sa on rudder
JR 10DS receiver with 5.5v regulator and TP 1320 2S battery.
PGB carbon tube, and 3-1/4 great planes spinner.

Harris

With the long servo arms needed for the ailerons can anyone state their ATV and rates? If we have to turn the ATV and/or rate really low then the resolution is going to poor and servos will wear more quickly.

Colin.

Is anyone out there running with the CG set at 205 mm like it says to do in the instruction manual? I've combed this thread, and it seems that no except Jason is running at much over 195 mm from the leading edge.

Also, is anyone running with aileron differential to compensate form the offset hinge line, or is equal up & down travel the norm?
