Ok folks,

I'm very seriously considering pulling the plug on this Edge on Tuesday (payday). I've been eyeing the 28% for a little while and got to hammer on a DA50 powered one (not the new version)this past week and was thoroughly impressed with it.

Anyway,

I'm thinking of a ZDZ 80, with Hitech 5955's all around. My only real question is does anyone think that a single 5955 on Li-ION will work on the ailerons or should I consider a pair of 5985's (5945 replacements) on 6volt. Twin 5955's would be major overkill but there's nothing wrong with that either. I would prefer the 5955 because of the titanium gears as I hate replacing gearsets every now and then when they start to get sloppy

I've been reading all over the place that the 5955's will take 8.4 volts and put out over 400oz's of torque.

Does this plane have a canister tunnel already there or must I build one

BTW...the link on the WH homepage for the manual does not work for me, so if someone has a link to one that would be greatly appreaciated as I like to go over the manual before I make a purchase.

So other than the servo questions I'm thinking along these line for a setup

ZDZ80
Header and Can (if possible)
5955's everywhere
3 2400mah Fromeco Li-ION's
3 Fromeco Badger Switches
Smart-Fly SuperReg (only if I need the 6volt option) and Power Xpander
Smart-Fly optical Kill
JR2000 receiver
4" Pete's CF Spinner
PT Models Prop Probably a 27X10

I'd look into the 3W 80. I flew the plane used to test out the wing design, which was an Extra 260 with Edge wings. We're at 5000 ft. of elevation and it has no problems going verticle. You can snap it and it'll keep trucking along towards space. Plus the 3W is $600 at Aircraft International right now. As far as servos go, a single 5955 on the rudder will be enough. I'm about to buy a 35% airplane and I'm putting 2 5955's on the rudder, a 5955 on each elevator, and 2 5985's on each aileron. As far as the canister tunnel is concerned, I think you'll have to build one, but it shouldn't be too bad. It's just blocking off any heat from getting into the fuse.

Bn,

Yea I saw the price of the 3W and also the ZDZ (675 on TBM right now). I'm looking at the weight difference and at 3/4 of a pound lighter for the ZDZ, that's significant. I have my first 3W which is the 55i in a Yak and it pulls like there is no tomorrow. Everything else I own is a Da50 or Brison 3.2. This will be my first 33% plane so I'm just trying to figure out what would be my best setup for the price

So you are suggesting staying with the dual servos on the ailerons?

Regarding the voltage, why not run a little lower voltage and be sure of what you've got for awhile? Other than the cost of the regulators, is there a reason not to regulate the voltage a little? You can bump it up later if you want.

Depending on where the servo pockets are, you could easily get away with only one servo per aileron if you install GOOD linkage. No cheap stuff and no slop.

I would not do the Badger switches. I have one and the mounting holes end up much to close to the edges of the required cut outs, causing a somewhat insecure mounting. The nylock backing nuts also also interfered with by the nylon risers that the switch is mounted on, making the act of tightening the nuts a cautious one. The pin switches are actually better. It's a nice switch, but the mounting clearences could have been engineered a little better.

The rest of it sounds just fine.

Sir I have the afore mentioned test plane, Mine has 4 5645's servos. The location of the servo pockets would make using only one servo a bad idea. the new 5985's would be great on 6V.

And Ben is corect the 3W 80XI is a real power house evan at this altitude.

Thanks, Mark. I was wondering how the aileron servo pockets were laid out. I didn't know if the wings had been cut for a center pocket or not like the Giles. No center pocket, no single aileron servo.

Just rember mine are the prototypes...production wings minght be different.

Pat and Mark,

Thanks for the input, twin servos it shall be and I will use all 5955's at 6 volts, overkill, yep, but I like overkill [sm=teeth_smile.gif].

I agree the badger switch hole could be better but I found that using the socket head servo screws from Microfasteners put in at a slight angle works well. I have used the pin switches for a while now and although I lik them as much, I have found that I tend to miss my pants pocket at times and I lose the pin in the grass, especially if the red flag has come off.

I'm still debating which 80 to get though. I have never owned a ZDZ and have one 3W (55I) so my experience lies in the 3W but I like the idea of the ZDZ being 3/4 pound lighter but at this time it is 75 bucks more than the 3W if you go to TBM's web site and order the ZDZ from them. Now if only Da would come up with a 75 or 80

Mark,

Would you be willing to share you layout with me? I know the engine but prop, muffler (noise is not too much of an issue but I would prefer to be somewhat quiet) placement of the electronics, rudder servo in the tail or pull-pull, etc...

I don't think the ZDZ will be 3/4 of a pound lighter unless the listed weight includes the ignition. The 3W is 5.05 lbs. with ignition. The main reason why I mentioned the 3W is because I didn't know the ZDZ was also on sale, but also because of customer service. I don't know what kind of customer service you can get with the ZDZ. I've heard of people trying to call Mike at RCShowcase and just getting the machine every time. After getting a bad Czech engine and having to deal with Horizon's customer service is the reason why I bought a 3W. However, it's your money. If you want the ZDZ go for it and have a blast. I'm willing to bet it's a great motor, but like I said, I had a bad experience with a Czech made motor and so I'm probably going to stay away from them.

Ben,

those are the kind of things I want to hear, both good and bad. I've heard a couple of people having problems with 3W, specifically Aircraft International. I have purchased various items from AI (engine, props, etc) and just props and one Roto Engine from RCShowcase and have never had a problem with each.

I have heard that ZDZ engines can be hard starting at times. I'm pretty impressed with my 55i. I had created a problem with it at first by getting a piece of wood lodged in the reeds. Once I got that fixed, it now starts like clockwork everytime. Ignition on, close choke and 7 flips and it barks, open choke, 3 flips and it's purring. After that first start and up to roughly 1 hour later I can usually flip it once, sometimes twice and it starts with no choke.

Hmm, I think I'm selling myself on the 3W....

Bubba.........I have a ZDZ 80 in an Hanger9 Extra 300L (The 1st one) and it has over a hundred flight's with never a cough. It starts very easy, and has almost as much power as a DA 100, and runs just as smooth. I have no way to compare the ZDZ 80 to the 3W engine. But I will highly recommend the ZDZ 80, and I'm pretty particular with my engines. Good luck with whatever your choice is. Bob

Bubba.........I think the reason some guy's have a hard time starting their ZDZ's is because.......after a certain peroid of time, the switch on the ignition will turn off, and have to be recycled.

bubbagates

My Feedback: (32)

Bob,

So it's the same as the 3W ignition. If you do not flip the prop in a set number of seconds the ignition turns off. I also think it does the same thing if the engine does not at least fire after the same number of seconds.

Keep it coming folks. The plane and whatever engine I decide to go with, will be ordered tomorrow

Let me also mention this in all fairness. I had a ZDZ 40cc that I never could get to fly out a full tank of gas. Went back to the factory twice, and had a new carb on it, but it still was the worst engine I've ever owned. Finally gave it away.
Caution.....I read on one of these threads that the "new," ZDZ 80 "Super" was not as good as the old one. If you're looking to buy one of these, I'd do as specific search on that engine. Bob

The main technical reason that I prefer the 3w80 over the ZDZ-80 is the ZDZ's carb location.

It ends up requiring a U shaped cutout in the firewall, and the carb sits in the middle of the firewall (half way through) making it hard to work on.

The 3w has an extended manifold that puts the carb well behind the firewall, a much smaller hole is required. All around I think it's a more well thought out engine.

You may also want to review the review which includes great flying videos and a lot of information.

Thanks folks, I am really leaning towards the 3W, 75 bucks is 75 bucks in this case. Both RCS and AI are within 100 miles of me so no matter which one I get, I can usually order it by noon and have it the next day while paying normal ground shipping.

Tom,

Just to be sure, do you have at least one in stock? I plan to give you a shout tomorrow pretty much right after you open. Also, could I get a link to download the manual please, the link on the website does not work. If you prefer, you can PM me with it.

You have two primary dealers of 3w engines in the U.S. Aircraft International and Cactus Aviation. The first can sometimes be a little difficult, but the second is usually a good place to go if there are any issues. Bobby's pretty good with the customers

Thanks Pat,

DOD has a good thread on this plane. I was just over there checking it out. I'm pretty sold on the 3W at this point. Since I'm on the East coast, I'll do the AI route

rctom

Email me about the manual, I'll attach it to the reply.

I've purchased an engine and props from AI and never had a problem. I know some people prefer to deal with them over Cactus, but to be honest, I like them both. I tend to buy more from Bobby at Cactus because he has online ordering and he's in my region. As far as the ZDZ's go, they're a good engine and I heard the hard starting has been fixed. But since you have the 3W, I'd say stick with them. You can fill both up from the same can. Last I heard, ZDZ's like 40:1 oil, but that may have changed, I don't keep up with them like I do the 3W's.

Bubba, here are some pictures of my 260 wildhare with a 3w 80 & jmb can that i put a tunnel in for my can set up...same fuse as the 540. if you need anymore let me know.

Why dont you talk to dick hanson about the super 80. i have been talking to flyinrazrbak about the 80's and he was telling me that the zdz super 80 has more power then the 3w 80 modifed on a pitts style muffler.

I have a h-9 33% cap here im going to try the zdz super 80 on and see if there's that much of a difference. but that wont be for awhile

Yea, I have the aluminum one on the 55i and it took very little "persuasion" to get it like I needed it

BTW, I just pulled the plug on a red one and as usual Tom was excellent and he got the link fixed for the manual to boot

My next call is for the engine, then I'm broke for 2 weeks. Oh well I can always eat rice and Mac and Chesse [sm=tongue_smile.gif]
