New H-9 Sukhoi set up
Got a few question's about setting up my new sukhoi I am planning on using a ZDZ80cc single if I can find one I can afford. what I am not sure about is the servo requirements that H-9 recommends, are they enough? 60 oz. on the ailerons doesn't seem like enough. How did others that have this plane set it up? also I plan on using either Hi-Tech or Futaba's new servos non digital. and a pcm receiver with 2 at least 1400ma. battery packs for the radio system. Anybody got any suggestions or tips for me on setting this plane up it would be greatly appreciated

Lee, I have the cap with a zdz 80, and I have Hitec 5645's all the way around. Except of course for the throttle. So far I only have 7 flights, but the plane has a very solid feel, and responds to stick movements as soon as you do them. I also have 1 JR 955 pcm receiver, with 2 6V 2700mh NIMH packs. I am very pleased with this combo! With the sukhoi though I think I would get a Big hitec 5735 for the rudder and mount it on a pull-pull configeration. This I think would help keep you from being tail heavy.

I have this same plane right now and its at the same stage yours is at. I too am probobly going to get a ZDZ 80, unless I can find a super sweet deal on a DA 100! I plan on going with hitech 5945 Digitals all the way around. I also plan on decking it out with all the carbon fiber replacement parts. Needless to say since I am a broke college student it will be a few months before it will ever hit the air, but I figure there is no use in only doing it half right, might as well go all out with it 
This is what I am going to use in IMAC competition this next year.

Hey I have a question also. I have heard with the ZDZ 80 the plane is tail heavy and some people are having to add a lot of weight up front. Does anybody know about this? If so have they moved the rudder servo internally and ran a double linked pull pull system like on the 40%'s?

In that case I will be sure to do the CF tail tubes CF tail wheel mount and move the servos up for pull pull. I DONT want to add weight.

I'd suggest the pull-pull setup regardless of the engine combo unless its an older heavy 100 twin. Been here and done this with Josh's Sukhoi with the newer 3W-100 @5lbs-8ozs., Three nicad's were up front, two under the cowl and the ignition battery was up front on the motor box and it was tail heavy yet... But we left alone for 3D work. The beast weighed a little over 25lbs..
One thing is for sure you must learn to use the left stick with a 100 on the front... Killer combo, BUT the ZDZ-80 @ 23.5lbs. has unlimited potential just not that of a 100 twin.

Mine is about 24lbs. And yes, I would love to sell the zdz off it, but cant swing the funds for a DA100 yet. Got to finish my jet first.
Vid of mine and zdz80
This was before changing to the Menz S26x10, big difference with the menz!

I have one with a ZDZ 80 that has appx 25 flights on it. I did not add any weight although I used a Pull Pull for the rudder. The zdz Hovers the plane with power to pull out. I am willing to sell the engine with muffler for $400.00 as I have Two zdz80"s and want to move into a DA 100. If interested call Ed 541-941-1147.

Ed,
I will be starting the Sukhoi/zdz80 combo soon. I am planning on a Hitec 805 w/pull pull for rudder. I am considering using pull pull systems for the elevators too. Yours balanced ok with the pull pull rudder and the elevator servos in the tail? If I could get it to balance that way I will. Would be much more simple to set up. How far behind H9 specs did it balance?
If Lee don't buy your zdz80 /muffler combo let me know and I will. That is cheap. Thanks

John,
You put 2 rudder servos and the elevator servos in the tail didn't you? Wow, that seems like it is way back there. Didn't M McConville release the correct cg was 3/4 behind center of wing tube? Wow, can't get over 2 inches! I watched your video and that helped me make up my mind on the Sukhoi. Thanks for making the video. I want to avoid lead if possible. If I could get this plane to 24lbs or less I think it will be great. Probably won't be happy with anthing over 25lbs.

I used the Hitec Jumbo for the rudder and the elevator servos are in the stock position. The plane ballanced about 1.5 inches behind the tube. That set up worked well for both Imac and 3d. The plane does great Knife edge, Waterfalls, Harrier Rolls and Hovers well. The only dissapointment I had was wing rocking in Harriers. Tried spoilerons but still had significant rocking compared to my H9 Cap. Hope thishelps Ed

Thanks Ed.... Do you think the rudder servos on the tail of John's plane compared to the pull pull on yours makes up for the 1lb of lead in John's nose? Plus, his cg is still more aft... Ed, do you know what yours weighs? Thanks.... Keep me in mind for your 80.

Yes, all my servo's are in the tail. I didnt want to mess around with the mounting of servo's in the center and the pull pull bs. I just wanted to fly it. Its 24lbs with the 1lb of weight in the nose and flies good. I did get the new CG, and with 2lbs of dead weight I couldnt get close to it so I flew it where it was and pulled more weight out yet! No fear.

guys sorry to ask a dumb question here but could somebody please tell me the benefits of digital servos I have never used them before so I am unsure if I really need to add the extra expense of 7 if I go with the pull/pull set up or 8 if I go with the stock set up. I don't fly IMAC or anything else yet. but who knows. Maybe Later

Digital servos are more precise in their movements and centering. They are supposed to have more holding power also. Another advantage of digitals is you can program them to work together when you have 2 servos working together on one control surface. I have had planes with digitals and many, many without, and to be honest I can not tell a difference. Some people say they can tell a difference, but if you use a good quality non digital it would be tough to do so.

HOw did josh like the plane? I saw his video entry (and win) in the DOD contest. Its really awesome that somebody can only fly as long as he has and become so talented. I expect that we will be seeing a lot more of him in the future. Did he ever get this airplane torque rolling on the deck? And, how well does this airplane handle harrier rolling circles? Finally, do you think that the ZDZ 80 produces enough torque to get a tight waterfall?
