Anyone flown the Hybrid with a zdz 80? I have one laying around its the same phisical size as the zdz 60 thinking about dropping it in this bird!

Spacey

What is the weight difference between the 60 and the 80?

Hmm, well I know of a 3W75 combo but not the ZDZ80. If it will fit then it should work fine. Probably use the inverted pitts muffler setup but be careful on the power. I here those single cylinder ZDZ engines are very strong. Throttle management would be an absolute must ....that would be the left stick!

The 60 weighs 4 lbs and the 80 weighs 4.2 lbs. The dimensions on the 80 are the same as the 60. I have the inverted bison muffler. The DA 50 weighs 2.94 lbs.

If I were going to build one of these, and I may. I would use the zdz 80. I flew OMP's with the DA 50, and although it had enough power to do what ever you wanted if it were my plane I would have wanted more. I will say this though, I really like the way the Hybrid flew, and it was very stable in all attitudes that I tried with it. If you do go with the zdz 80 you will have to be as Mike said careful with the throttle. A zdz 80 will fly a 23-24 pound plane unlimited. You are going to be putting it in a 16-18 pound plane. There is a big difference in weight between even 23, and 18 pounds.

But it ought to be a MONSTER with that engine!

If it was up to you would you sell the 80 and get the 79" YAK or 80" profile or stay with the 80 and put it in the hybrid? I have all hitec digital servos and pull pull set ups to go with the large hybrid. With my 9C I could set the end points on the top end of the throttle servo! The 80 would increase the wieght a 1.5 lbs compared with the DA 50 would I notice the additional weight. Would ballancing the CG work without addition lead?

ZDZ 80 weight with muffler , ignition, engine. Ignition 4.8 oz muffler 11.5 oz engine 4.2 lbs

total 5.5 lbs

Would this weight effect the flight performance and ballancing?

I would keep the 80, and build the hybrid. That plane has a huge wing, and could easily accept the added weight of the zdz. I have seen pics of people flying with a zenoah G62, and the zdz 80 actually weighs less than the G62. The hybrid I flew was told to be slightly tail heavy although I am not sure it was. But if it was with a DA 50 and can than a zdz 80 with pitts muff can't weigh much more than a DA, with can and header???

I haven't flown there big yak, but I did build one of the big edges a couple years ago with a MVVS 2.15 gasser. I feel like the hybrid flew better than the profile edge did. I wouldn't limit the trottle throw with the 80 I would just be mindful of how I flew it. It's a 3D plane it's supposed to be flown using the throttle. Even most of the Big scale planes can't be flown at full throttle during most manuvers. Get the Hybrid, build it, fly it, and never look back. You're going to have an animal with a zdz 80.

Even of it came out slightly nose heavy move the rudder servo to the tail. It would be easy to build that option in while it's under construction. You could prolly move enough stuff around in this plane to get it to fly on a light glow motor, as well as a 100cc twin. It's just a matter of where you place things.

I have NO experience with the ZDZ engines. My biggest concern would have to be vibration. Would You notice an increase in vibration going from a 50cc to an 80cc engine? Although the Hybrid is constructed VERY well, it is also constructed very light.

capthis

My Feedback: (67)

Yes a zdz 80 will vibrate more than a 50cc. But a 50cc can shake pretty good too so I would imagine the airframe will take the extra vibration. If they are holding up with a zenoah g62 a zdz 80 isn't going to hurt them!

My Feedback: (21)

The BME 50's shake pretty good on the 80" planes. They hold up just fine.

I wonder how that MVVS .58 would work on the Hybrid. The MVVS 2.15 has almost no vibration. I may have to give that try on my Hybrid when Mike's done building mine.

capthis

My Feedback: (67)

You still flying that old, has got to be worn, out MVVS??

I doubt that would be enough motor for the hybrid. It would fly it and prolly hover but I doubt you would have much left over for the pull out. I know it's a strong motor, but that hybrid is a big plane. Not to mention quite a bit heavier than the profile edge.

STLPilot

I'm talking about the 58. Morris is claiming that thing peaks at 9.25 Bhp. Which is more then the ZDZ 80. It's also damn purty. I'd build a clear cowling to show the engine off.

Shiyat ... my MVVS is running like a swiss watch now. Only prob is that the pipe header bolt holes are too soft and have broken. I've switched to spring mount, but that's not working too good. Going to get it tack welded this winter. Love the MVVS 2.15 and everyone that has ever seen it run loves it too. Sounds like you've wanted to see this plane die a long time ago ... I've tried my best and it won't happen.

I run a 26 x 10 prop on the ZDZ 80 would this size create any issues with prop clearance with the landing gear? I guess I could change prop sizes to a 24-10 0r 24-12. What prop sizes can you run with the hybrid as far as prop clearance is concerned?

capthis

My Feedback: (67)

A Da 50 can have up to a 24-8 so I doubt a 26" prop would create problems. I really don't know though. But if guys are using the 3w 70 they run a 26" prop as well. You could always go 25" 3 blade.

Ok, I'm back from playing all weekend. Here's the scoop right from the designer: The extra weight of the ZDZ80 would be no factor at all. The wing loading on these funfly style planes is so low, you could hand two ZDZ 80s on the nose and the plane would still fly awesome. Brian (CAPTHIS) is right on the mark in that this combo would be a monster so you'de have to be careful not to overspeed the plane. But that's normal anyway for us fun fliers. If it's the same size as the ZDZ 60 then it will fit just fine. Balance will be no problem as most Edge designs are tail heavy by nature and you have to move everything as far forward as possible to achieve proper balancing. The extra nose weight will allow you to relax this constraint and put stuff pretty much anywhere. I also don't think vibration would be a problem as all single cylinder gassers vibrate somewhat; the plane is designed for this. Just make sure you have good glue joints as always! Oh yea, prop clearance is no problem.

HMMMMM. ZDZ 80 huh? Maybe I wont wait for the 55xtreme. Heck, since the BME 110Xtreme weighs less than the ZDZ 80, no never mind.
Would be kind of cool. Only in the funfly/profile forum can you go from a DA50 to a BME 110xtreme in the same thread.LOL

I ran ZDZ80 on 18 lb plane (see pic) - 1500 sq in - NO vibration issue and power performance made me change my mindset on really good power to weight setups.
My new plane for the engine will be in same weight but more sq inches (and scale).
These engines - simply broken in and carb adjusted corrctly are quite smooth.
Although there are paper claims of smaller displacement engines of same power - I simply don't accept that these claims have any merit -
The best of them I have seen still do not beat a tuned exhaust ZDZ60.-which turn Mejzlic 24x10 's over 6500
Anyway - should be a great combo on the Hybrid.
(at our altitude , the 50 powered "super performers" fall flat as a pancake)

what size prop and brand do you recommend?

It really won't matter - anything that runs - I like 26x10 MenzS clipped a bit for more instant revs - makes for a stiff prop

My Feedback: (67)

You dang skippy it would be cool! I can just see the twin cylinders sticking out both sides of the cowl! Talk about throttle managment though! A 110 will take a 30 pound plane straight up till you can't see it. Imagine what that power would do on a 17 pound plane?? [X(][X(][X(][X(]



On my zdz 80 I have run the mejlick, menz, and airwild 26-10 props. Liked them all!
But I think the airwild had the best pull, and the best braking.

My Feedback: (28)

Would a 26-10 look to big on the hybrid .It can run a 24-10 or 12 was wondering if that size would be better. I currently fly the 26-10 haven't tried any other sizes.

One of the things I'm doing to tone down the 3W75 I'm putting on my Hybrid (I'm fixing to start building it) is to put a 3-Bladed Prop on it. Quiter as well. The only dilima I'm having is the Canister muffler that I'm also going to use. I've got to either get a custom header made or by a flex pipe for the canster to sit right above the landing gear. Width of the fuse is not a proble either and I'm thinking of running the exhaust out the side instead of down The gear might be in the way and that's why I'm thinking of doing that? No matter what I will end up with a very quite but powerfull 3D monster...
