I just ordered the H9 Sukhoi for my ZDZ 80RV and was wondering if anybudy have some pic's of there pull pull setup? I'm thinkin I'm gonna have to but the rudder servo's uner the canopy to get this thing to balance rite. What do you guys think?

You probably will, the engine is LIGHT next to what they recommend.. Have one on mine and just added some weight to it instead of going through the hassle of the pull pull...Not the best idea, but more than enough power.

Did you use the H9 hardware kit on your or did you use your owne linkage setup? Is the zdz easy to install?

JohnVH

My Feedback: (38)

I used all H9 hardware kit, but put 1/4" longer arms on the elevators as I could not get enough 3D movement on them.
The engine is fairly easy to mount, I have a thread here with lots of pics on how the engine fit on mine. Search for it and youll find it..

I just purchased a H9 Sukhoi also and I am also planning on putting a ZDZ 80 on it. I am going to do pull-pull using a Servo Ganger from RCSuperstore. I should have it installed later this week, I will post some pics once I have it installed.

As for hardware I am putting together all my own stuff, it is all basically the same as the H9 Hardware pack but since I am putting in the Pull-pull I don't need all the long pro-links in the H9 Hardware pack.

What kind of hardware are you gonna use? Once you get the photos please e-mail them to if ya could. I should have my Sukhoi this week. Cant wait!!! You gonna put smoke on it?

My Feedback: (9)

o ya, Do you have the measurments for the pull pull wire exits in the fuse?

JohnVH

My Feedback: (38)

Your going to need something for the elevators, and ailerons yet. The hardware pack is nice.

Glenn_O

No, I don't have the measurements for where the pull-pull will exit yet.

Yes the hardware pack is nice, I bought most of the same stuff but I did upgrade a few things, plus I already had some of the stuff. I bought H9 Pro-Links for the elevators and ailerons. I just meant that using pull-pull that you won't need the extra pro-links for the rudder. If you don't have any of the parts already, it is probably a little cheaper to go ahead and buy H9 Hardware Pack

I'm putting together the same setup now have installed the pull pull set up using Hitec 5735 260 oz. giant servo. Call nelson hobbies he has offset servo arm 31/2 in. install cables straight do not criss cross, holes in fuse need to be at the point where the fuse is 31/2 in. wide. Same as servo arm with 3/8 offset that will match offset at rudder if you use nelson (rocket city) hardware. Mount servo as close to wing tube as possible and keep tail as light as possible should balance 1 in. behind tube with out any extra weight. should weight less than 24 pounds. I'll try to post pics. ASAP hope this helps.

Here is the set up in my H9 Suk. The servo tray came from Creek Hobbies and is very very nice for the money.

I used Dubro large push rod exits for the exit for cable I chose not to use a tray for a couple of reasons. 1. I did not want the extra weight, 2. I wanted to get the servo as far forward as possible this plane has a tendency to be tail heavy.
The cable will enter behind former you will need to drill holes to clear, I used long drill bit from home depot for this job worked great. with the dubro fittings you will have a nice clean looking exit. If you are interested in the Kevlar cable and cable ends I can get you there name and number they are a composite co. in CA. Hope this helps.

Thanks

Attached is the web site for ACP sales they have both kevlar cable and kevcord connectors with 4-40 threads can be threaded to ball links, and .047 hole??? large enough for cable to fit thru, then tie a knot CA and pull tight.

Wow, I just balanced my H9 Sukhoi w/ZDZ80 before adding my rudder servos using the "updated" CG's now recommended by H9. After all the talk about the ZDZ80 being so light that you would need pull/pulls and lead too. Mine came out nose heavy until I stuck the rudder servos back in their designated positions. With them in the rear I managed to get the "precision" flight CG at 13/16" behind the center of the wing tube (1/16" behind the rear of tube). My setup is:
1.75" aluminum standoffs on ZDZ80
Throttle and choke servos on motor box
1800mah 4-cell sub-c nicad pack on top of motor box
2700mah 5 cell NIMH packed in fuse side up against 1rst bulkhead
Tank in stock position
Here are some pics of the nose area which aided the balance. Thanks for those who warned me not to jump on the pull/pulls until I moved any/everything forward.

That is odd, I needed 1.5lbs of lead on the firewall to get 2" behind the tube on cg! That is with the all the servo's in the tail, two 1800 nicad packs beside the battery, and a 1800 pack for the ignition on top of the firewall.....

My plane sukhoi should be done this weekend. It will be interesting to see where my CG will end up. All my batteries are up front + a showtime smoke pump!!! maybe I should check my balance before i put in the servos.....


-jelaird, nice install on the equipment!!!!!!

ok, im confused. I noticed that jelaird has 2 servos right next to the ignition - wont this cause interpherence??? If I can place the reciever battery pack and throttle servos in the front of my 29%cap, I can remove 1.5lbs of lead! Whats going on here????

The only people i've seen doing this has been people with PCM radio systems. And they say they never have any problems. I guess what ever works!!!

JohnVH

My Feedback: (38)

PCM makes no difference, its all in the setup.

Mine are close also with no problems.
