Glad you like yours also Pete. Do you have any coupling issues? I definitely need to see your wall, because mine feels a tad mushy. Please post some vids when you get a chance.

I haven't gotten a chance to fly mine much because I had to send my DA back for inspection. It seems to be just a broken gasket seal.

Hey Pete,
Is that the CG yak that you put the DA 50 in?? How does it fly???

Yes , Too BIG,,, But a blast, pulls out like a ELE. plane , Or a rocket , I just couldn't put a 120 4cyl in her .. I think a sato 180 would be super .
I flew the lanier today again and , Elevator is truly on line , NO rock.. You just have to keep up witih the ailerons .. , And yes I will post a video as soon as I can get someone to video it ..

I have a ZDZ 50 NG for this plane, but recently read the mag review and they put a ZDZ 60 in it. I have a line on one but I'm wondering what people think? Is the 50 enough or will the required nose weight not help things. How about the zdz 60?

Any help is appreciated. I may need to decide on the engine tonight...

Peter

If you look at earlier pages, you can see how I set it up. I bolted on a DA50 on mine, and I don't need ANY nose weight. But you do have to mod a pull pull, put your batteries in the front, as well as your throttle and choke servo.

The proof, his AUW is 19 lbs, mine is 17.2

Thanks BoneDoc,

Can you comment on the hover pullout? I don't mind doing the wing servo mod, and a pull pull - so perhaps I'll stick with the 50.

Peter

Great post especially the contribution by bonedoc, I have just ordered one along with a Evoultion 58, I am planning on using hs 5645 mg's throughout do you think they are up to it??? Great idea on the pull pull... the video links dont work any longer any way to repost them or e-mail them??? Thanks guy's kind Regards Colin

you guys can go to my website www.young99.net

Pullout is decent, but not quite like a rocketship when I strapped that DA to my H9 260. If you look around, you will find that most WH planes are 17 lbs plus though, and they all claim excellent pullout.

Colyn,
I would say it's probably enough for the rudder, but I am personally VERY happy with my 5955TG on my rudder. I would say that if you go with 5645, you can probably go with one per wing. If you don't want to do the mod and stick with 2 servos / wing, then 5625 will give you faster response. That's what I have.

Personally speaking, the most anoying aspect of the 2 servos per wing is my aileron differential mixing. I have to figure out how to do it on my 9C that I could use only 1 mix, instead of taking 4 mixes.`

Hi Josh thanks for the fast reply, i went to your site today and watched the flights, I am inspired, nice looking children too I am also inspired by the rudder set up.I will be using the Evoultion 58 this motor is about a pound heaver than your DA, I am going to call Graphtec and get a wing tube, horizontal stab and landing gear in CF, I am wondering with the weight saving if the mod on the rudder will be needed??, I so dislike adding weight to balance my models so I want it to balance with the gear used by maybe moving it around, do you think it needs a powerbox?? for servo's batteies I am going to but a Hitec Digital servo programmer instead of matcbox's.I am also flying with a 9 c super, do you have a y harnes on the two sero's in each wing and then use two channels mixed with independant mix on the radio???? I have a Dave Patrick ultimate using 4 channels for the aielrons. dont like to use three y harnesses. This will be my first gas plane and first biggish one I have a funtana 90 which is the biggest I have flown, is the transition from glow to gas and the size an easy one??? you certainly made yours look easy to fly...it looked like it landed pretty much on it's own, even the take off...man that was a short rollout!!!! [X(][X(] Thanks Kind regards Colin.

My servo setup is rather cumbersome. I have the Left wing on CH 5 & 6, and the Right wing on CH 1 and 8 (or is it 7?). The Elevators are on CH 2 & 7 (or 8, I don't recall which). I think that you can master / slave the channel so that the wing servos will function as a unison, but I haven't quite figured it out yet. It's setup ok now, and really the only mix I typically use is one to neutralize the roll / pitch on KE anyway. I find that I need about 15% Rudder / Aileron mix to take out the roll coupling. Everything is plugged into my Futaba PCM receiver. No powerbox used here. I didn't have any issue with power, responsiveness, and glitch, so I haven't had the itch to upgrade to a powerbox. I suppose, however, a powerbox will make setup more convenient. I think using a Y Harness with a programed Hitec servo will be just fine (Just use two and use the flapperon mix on the radio). I would if I have the time to do it, but once you've got everything kind of set up already, laziness kicks in .

The transition from glow to gas will be pretty easy. I would say the most important thing moving to larger aircraft is to grease your landing. You have a larger mass, and so stall from 2 feet will take a harder toll on the airframe. On the other hand, greasing your landing will be easier, as your preceived speed of the aircraft will be slower. Just keep applying power until your wheels are ready to touch down.

If you haven't put everything together my advice is to just build it stock (except for the horns on the elevators and rudder. I think the stock is too flimsy for my taste. I switched it to the H9 rocket city-style horns (because that's what I had). I would first mount the engine, and all the servos EXCEPT for the rudder. Do that last. That way, you will have the flexibility of doing it pull pull or just put it in the rear to get just the right balance.

I would personally avoid the CF stuff first. They are lighter, but will also break on hard landing. Alum will just bend some. I would just build it, fly it, then switch to CF if you're still not satisfied with what you got. If you do go the CF route, you probably will be able to bring the weight down to 17.5 lbs.

As for the engine, I heard the EVO 58 is a real powerhouse. Just make sure you don't break it in the stand. All gas engines are meant to be broken in while flying. Just use the suggested prop and proper break in, start up procedure and you really shouldnt' have any problem. You will definitely like the power of that engine, since it's reported that it can even haul a 33% aerobats (that's typically powered by 80 cc engine).

Thanks for your time josh I have just won an auction on e-bay for the evo 58 motor....one last question how many batteries and switches are you running and for what for. Thanks again Colin.

No prob, that's what the forums are for. At some point in my learning curve, someone also showed me how to do things right.

I have 2 batteries, one for receiver, and one for ignition. I run LION with regs, but not so much for weight saving. With LION, once you charge it, you don't need to worry about them loosing their charge. So, you can fly it 2 weeks later, and know you still have enough juice. I'd say 2500 mah for receiver, and 1500 for ignition should be enough.

Josh,

Excellent help here in this thread. Your plane looks like it flies great. I just picked one up myself. What did you do when hinging the elevators? It seems as if I will have to hack off some of the hinge. Is that what you did? Thanks for the help.

Thanks,

It seems as if I'm the moderator for this thread, lol.
yep, on the innermost hole so it doesn't bump against the stab tube.

Has anybody got any comments on the servo arms to be used? There is no mention of it in the manual and the ones in the pictures seem to be DuBro HD.

I installed intially the 1.5' H9 machined arms, which are very tight. They do however look too large and so far off to the side that the linkage to the hardpoint might get a bit offset and diagonal.

Instead of measuring a direct line from the servo side as per the manual (which hits the middle of the hard point), the line from the arm external hole goes to the outside edge of the hardpoint. If I want to drill in the middle, I will have a linkage that is not at 90 degrees to the servo.

You will have a much stronger and linear aileron response if you do not have your pushrod 90 degrees to the servo at neutral. Instead, the pushrod should angle in towards the servo slightly. Draw a line along the wing right against the body of the servo, towards the aileron. Then move the aileron control horn about 1/4" outside. This gives you a set-up that is strong throughout the servo travel. I'll try to find a picture...

Thanks for this info.

If I do what you describe, I would have almost an inch the connecting rod would have to go back towards the horn. If I position the servo the other way (output shaft toward the aileron, not towards the wing like the instructions show) I can even increase this angle.

Is there a recommendation how much the connecting rod should go inwards to get the maximum effect of this setup?

And another question - does this rule apply for elevators as well? The diagonal line there is stronger and there is definitely an angle at which the rod connected from the servo arm up to the elevator horn...

See if this may help:

Thanks, I looked at the video. Pretty good information.

I just hope I can achieve the right setup with JR servos (not programmable) using two Smartfly matchers.

Try this link http://www.rccanada.ca/bb/viewtopic....asc&highlight=

or look here:

Very interesting conversation and the dime just dropped for me.

I now understood the notion of the servo still being effective at full throw if it's slightly offset out and the arm angles in at neutral. On the flip side, if completely parallel ay neutral, it will be investing very litle of it's motion to actually hold the aileron at full throw...

Actually, if I extrapolate, in order to identify the linkage best angle at rest, it should be parallel to the servo at full push throw. So one would need to move the arm to the best angle (between 45 and 60) and measure a straight line from the hole to determine the right horn location.

Furthermore, the arm at neutral should not be at 90 degrees, because if that is the case, during pull (aileron up), you will encounter an area of low yield and low hold, probably somewhere after 50 - 55 degrees of throw...

You got it!

Peter

I used the Dubro HD for the ailerons, and 1.25 aluminum one for the elevators. Rudder is pull pull to conpensate for the DA being light

Josh,

I know I posed this question a little earlier, but my hinges for the elevator seem extremely short. Were yours cut down to almost one nub left on the hinge? Thanks for the help.
