Did the Right wing, (Starboard Wing) have a greater angle of attack than the left?

Hi,

Time to pick up the real stuff after a long winter-season here up in the north.

I have ordered a couple of Cleveland-carbon props ( 16x11 3-bld) for my Integral / YS 160DZ which i hope will work out fine. Anyone tried this combo ?

The 17x12 route is a bit fast for my style, hoping the 3-bld would shift from 4th to 3rd gear

hello
I'm soon ready to fly my Integral.
paint is done and starting to get the engine in !
I have tilted the engine (YS 170) over ca 10 degreed to avoid the manifold to hit the belly pan , it seems maybe this will be enough there but one thing i didnt notice is that the pump probably will hit the b.pan when running have ca 5mm clearence here.....
the Engine is mounted on the YS M mount on some alu pieces.
my question is ......
Have you guys tilited your engines over ....how much does the engine moves on this YS mount(havent use one yet)..and have you made holes in the b.pan to manifold and\or pump...and which type manifold you use , i have the hattori with low rise #823.
some pics off the install and b.pan holes whould be nice!

I have just test run the 170 in my Goodshot and must say it was pretty hard to start ...my starter that turns the 160 with no prob. could not start it .... maybe i have to be hard to it and give it some more cells to rise the voltage some, but engine runs nice !

Rune,

I have my engine offset in my black magic approximately the same amount you describe. Unfortunately I do not have a straight on shot of the amount of rotation, but here is one from the front. it has worked very well with this setup and have had no problems with the header hitting the BP. I am running the Hatori 822 header with the 821 pipe. Ignore the fit of the chin on the front. This was done with only the front bolt in as I was taking these pictures for someone else and I didnt fit the back of the chin.

I have had no problems starting my 1.70DZ over my 1.60DZ. They seem to start and behave almost identical. I wonder if something in your 1.70 is a little tighter. My B&P starter drives both with no problems,

Hi Rune,

... Still waiting for the spring here, at least if you need to drive to the field ...The last piece of the road is still too soft. I guess beginning of next month will do.

Sending some pics of my installation. The Equipment used is slightly different than yours though .

ARA 140 mount , 822 header , original nose ring.

The engine is mounted "straight-up", but i needed to adjust the right-thrust additional 2-deg ( total of 4-deg). Working just fine; no rubbing or slamming in the engine-compartment.

Kjell Olav

thanks for pics guys....

i change to the hi rise header ..helped some...but seems that i need to make a hole in the belly pan for header.
I will run it some first anyway to see how much its moves, i have exepienced that is slams pretty hard and long if it back fires.

Kjell i have added approx 1,5 mm more on one side off the spinner dont really know how much that is but was after advice from B.Ollson at Rc Sweden.

Arch...compare to both the 160 i have the comp. is much harder , another norwegian that i know says the same , it will maybe help after some flights.

Rune,

In the picture you can see my side-thrust, quite a bit i must say ... The gap behind the spinner is 0.5mm / 3.5mm ; 3mm difference. Anyway; i don`t care about the look, as long as i get it right , time to practice and show up at the comp

In additional, i have placed the rudder servo in the tail as you can see, and replaced my batteries (2 x lipo 800 mah) from the tail to just in front of the tank.

Kjell Olav

Hi Kjel,

Does the plane balance ok with the YS 170 and the rudder servo at the tail? If you do not position it there, does it come nose heavy?

Can you please provide a side photo of the plane in order to see where exactly have you opened the rudder servo slot?

Also what servos do you use on rudder and elevators?

Thanks in advance,

Nikos

i have a question but I can say some mistake but On the picture where we can see the rudder servo we can see another part after the servo.. It sems as a shock absorber or something like that because I can see a cylinder but nothing else..
Could you confirm that or I have smoke too much of illegal things?? lol
Thanks
Best regards.

Hi,

I noticed that also. This is probably a servo arm dumper, (it is made of an RC car shock absorber) so that it does not vibrate and cause the surfaces to move at idle, it also eliminates battery consumption during idle. Reminds me a bit of the YS type M mount.

It would be interesting if we had some more photos and explanations by Kjell.

Regards,
Nikos

Hi guys,

Last year i flew with the rudder servo in the fuselage , and the batteries in the tail ( mounted on the horizontal stiffener ) , but now i switched places ; servo in the tail and the batteries in the fuselage ... Personally I like this setup better ; Directly rudder control, and easier access to the batteries. In additional, i can easily move the batteries around to fine-adjust the CG. By the way; my CG is 180-185cm with this set-up , which i like best for this bird , but if you want ,you can move the batteries further forward to get 170-175.
I guess your 170DZ has approx the same weight as my 160DZ (with hattori header and short-muffler).
Without the servo or the batteries in the tail , mine would for sure be nose-heavy , at least to keep the CG in this position ...

As you can see in the pictures , the rudder servo is placed approx 1cm behind the LE of the stab. This is my truly Futaba 9151, which feels plenty enough for the job. Anyway, this servo has a "standard-weight" so others will do just fine what the weight concern. The shimmy damper weight approx 20 gram, so there is plenty of margin to put the latest power horse in there ...

The elevator servos are the DS 3328 ( jr/graupner spec). These servos are 28 gram each.

All servos has HD twisted cables ( without ferrite core )

The Batteries are placed behind the landing gear-reinforcement as you can see ( 2 x 800 lipo ).

Youre right, the fixture behind the servo is a Damper . I have also mounted them in the aileron`s.
Well, i have only 30 flights with those yet, so time will show ... But so far everything looks promising, keeping the aileron and rudder rock solid (without the servo connected), and still allowing the servo to operate at it`s speed. ( high freq damping)
I have done some testing; oil-viscosity , piston/cylinder area , piston holes ( number and size) etc ...
Aluminum alloy (7075) keep it strong and light , oversize ball-ends make it tight and presise ... Actually this is a Buggy-competition damper ( XRAY ), and makes it possible to customize it as you want ( spare parts , options etc)

hmm, Hope this help a bit Guys..
Kjell Olav

Great info!! Thank you very much!!

I will probably place the rudder servo at the tail, it is a JR-8411SA probaby it is close to yours in terms of weight.

Best regards,

Nikos

... 8411SA is in the same weight category , no problem ...

The complete servo is lowered into the fuselage ( mounting brackets are flush with the skin), i have also build a balsa frame around the opening on the inside , and a horizontal web at the aft servo attachment to stiffen up. ( there is already a web at the front part )

Kjell Olav

Well my Integral i finished!
I have fedd it nicely during pregnancy so it ended up 4,9 kg...hmmm
stuff used so fare..
servoes ailrons...futaba 451 BLS
elevators fut. 9650
rudder fut 9451
trottel jr 8401
controled by futaba 12z and 5114 rx
battery shultze 2000 lipo with swithts and reg
engine YS 170 with high rise hattori header and the short muffler mounted on YS M mounts.
so hopefully fly tonight or tomorrow.
maybe change uc to save some weight
added 40 gr lead to balance it at 190 mm from LE.
Thanks to Torben from Denmark for help with som computerfiles for decals to the plane.

Hi Rune

Nice design !

What propeller do you use on YS 170 DZ and how % nitro ?
I use APC 18,1x11 and fuel with 25 % nitro. It's awesome !
Regards

Nice paint job!!!! Congratulation on your planes completion. I should have mine in the air shortly. I'll post some pictures. Good luck with it. Mike

thanks guys..
I havent run the 170 that much yet ...2 flights and 2 tanks on the ground.
so fare i use 18.1x10 and 30 % Rapicon...but i have 18,1x11 to use after break in!
The integral got 2 flights today , seems promising need much more right thrust than the fuse indicate ,and that old problem ....nose heavy.

congrats Rune,

Nice paint you got there, and now there are some different sheme of those Integral`s also

hi Rune
nice Plane [sm=tongue_smile.gif]
i have some problems with my new YS 170
5 flights then this happend and alittel chrash[:@]

Love the paint job Rune and the extension off the exhaust is a nice touch!! Is there a limit on this kind of extension, I thought it might affect the running of the motor by constricting the exhaust?

Torben,

... YS seems to have two different springs in the head for the 170 , and i guess the part-number confirm this .. "Normally" they use the same spring for both intake and exhaust..

I wonder, since i only have the 160 myself Do the springs have different lenght ( streched, or different number of coils ) or any difference in thikness ? which one of them was broken?

Kjell O.

Hi guys,

My Integral is now completed and awaits her maiden flight! See picture attached... The power plant is still an OS 140RX with a Webra Tuned pipe attached... The CG is curently just on the 170 to 175 mm mark and any suggestions here would be appreciated? Also, are there any traits I need to worry about for the first flight as this kite will be my first 2x2 experience from my trusty Leo 110...

Keep it real

Hi,

... Been Playing around with my Integral testing, setup etc ..
Mr Dingo enjoy to pull this bird around like a doll ...
... CG at 195 seems better now after some adjustment`s. By the way the current consumption with the shock-dampers is approx 70 mah each flight in average ( P-07 ++)

Now there is only one more tiny little detalj to sorten out get my fingers orginized ....
