I recently ordered the 28% WH Edge and the ZDZ-80. I went with the big motor because it was advestised at only 4.1 lbs with hardware and ignition, and since Tom Fawcett was recommending the MVVS 58, a motor heavier than 4.1 lbs, I figured why not have all that extra power. I received my ZDZ 80 RV from RCS and took it strait to the Post Office to weigh it. It weighs 4.64 lbs! Here are my questions:
1. Is the weight penalty in your opinion worth the extra power? (I will run a lightweght spinner, landing gear, Li-Poly's etc. to save weight on this airplane).
2. For those of you who have a WH Edge, Joe, does it have clearance for a 26" prop? (Bambula is actually 25.5")
3. My ZDZ-80 RV, ignition, spinner, Supersonic muffler, and Bambula 26x8 prop weighs a total of 5.96 lbs. Seems like a lot of weight for the 28%. What some other people's opinions?
4. With the ZDZ-80 RV up front on an 18 lb. plane, will I have time to pull the throttle stick back before I get to outer space? I like a real spectacular pull out
5. How do you compare Bambula to Menz-S for 3D flight?

balsa -

I think that you went a little overboard with a zdz 80 for this airplane as it was designed to run with a 50cc-62cc gasser.

1. I think it depends on what your actual ending weight is - if it is no more than 17-18lbs then you could be alright. According to the Wilde Hare web site the plane came out at 17 pounds with a Zenoah G-62, which is quite a heavy motor.
2. I don't have the plane yet, so I am not sure on this.
3. That sounds like a lot of weight for this size of airplane. I have seen the ZDZ-80 pull around the Hangar 9 Sukhoi like it was nothing (24lbs, 96" span).
4. Not a chance.
5. The Bambula will not let the motor spool up near as quick as the Menz will. The Menz is a much lighter prop and does not have quite as deep of a pitch as the Bambula. Also the Menz is really a 26" prop, not 25.5" like the Bambula.

Balsa, I had a ZDZ80 in a Lanier 30%Edge, sold the plane, kept the engine.
Bought a Wildhare 28% Extra 300, and a DA50 to power it. AUW 17 lbs.
After flying the bigger Edge at 22.5 lbs with the ZDZ80, I didn't even think about putting it into the Wildhare 28%.
I think it would be definitely fun, but you'd probably have to kill the engine for every landing as the Wildhare would float forever at a ZDZ80's idle speed. Won't be able to taxi around. The power of the ZDZ80 would really shorten the life span of the airframe.
I don't think you'd be able to hover it cause as soon as you advance a click of throttle, it would start climbing out.

Fun to do, but I don't think you'll enjoy the plane overall.

Is this Clayton from Henderson? I am going to go for it. My Funtana with Saito 100 weighs 5.68 lbs!!! It is still a pretty light Funtana. I can lighten up the 28% Edge the same ways to make up for the ZDZ 80. Another airplane that would maybe be better suited to the 80 would be the Lanior 30% Edge. My WH Edge with ZDZ-80 should have a 2.7:1 thrust/wight ratio

3D ONdaEDGE

Yep. I just bought Eddies 30% edge off of him. I like it with the 3W 70. I think I am gonna make it my IMAC plane and use my Sukhoi for 3D. Im still flyin my funtana with the 100. I love it. I did make one very good change though. I built a new rudder that is 1.5" bigger all the way around. It harriers better and has alot more rudder power. You might check into doing that yourself. As far as using the ZDZ 80 on the Wildhare EDGE, I really dont see a problem with it. That one that yall got over there with the Brison 3.2 flew fine. Im pretty sure you know throttle management flying a funtana with a Saito 100 so if you continue to practice it with the edge you really shouldnt have a problem. Plus, If you do crash the plane, you already have the engine to go on a H9 1/3 scale plane. Let me know if you get this thing up and running and I may have to make a trip over there to check it out. Good luck with it and we'll see ya later.

I had the Brison 3.2 on a 28% WH, but wanted more power. ..

I'll give a flight report after the "maiden". Initial prop will be a 26X10 Moki... I have seen this thing float forever too with aft CG, so a 8 pitch may be better.

You guys are nuts...I don't mean that in a bad way. I have a ZDZ80RV on the nose of a 20 lb CA 31% Extra 300L and it's way more power than needed. I mean it's a rocket out of hover...a ROCKET! Almost looks like a brushless foamy pulling out. FWIW, I'm using a Mejzlik 26x10.

What you guys are doing is overoveroverkill. Make sure that you have either an opto ignition kill switch or a servo on the choke because you WILL have to kill the engine to get the plane to land...and I'm not kidding.

The ZDZ80RV is in a totally different class than the DA50-R, Brison 3.2, etc...but you will see for yourself. Make sure you get video footage!

Good luck,
-Tom

I fired it up in the driveway today... I'm having second thoughts about this decision [:-] .. It responds like a drasgter with the Moki 26X10..

It also seems to be a shaker.. Need to take a second look at the prop balance.

It was a pain to get fired initially, and seemed to flood easy. Anyone have flooding problemg with the BING carbs.

Well I agree with you about us being a little nuts. There is a gap between the 50cc and 100cc engines. Most 50cc class gas planes just don't rocket out of a hover like our glow models and I wish they would. MVVS came out with a 58cc engine that is supposed to smoke the DA-50 as far as pulling power goes, at least that's what they say anyway. Anyway, if nobody ever tried to build anything nuts, the rest of us wouldn't have any fun toys to play with.

FreedomFlier - I can't wait to hear your flight reports and what the AUW is!

Balsa+Nitro.. I'm glad to see I'm not the only crazy guy.

I baselined my weight before making the switch, and I calculate the take-off weight with full 24oz of fuel will be >18.5 lbs. (See table). . I saved an ounce on the stand-offs, but had to add a servo for the choke, so it should be close.

The other weights, (except the G62, and J&A 4.2) are manufacture weights+ ignition/battery/muffler/standoff-mount etc.

FreedomFlier, I sure hope it 3D's well at 18.5 lbs. Even if it's a little heavy, it still would be a fun airplane just because of the ridiculous power. To save weight I was using Li-Poly's, fiberoptic kill and no choke servo, carbon spinner, hard foam wheels, and J&A side mount muffler which weighs 9 oz (some mufflers weigh 12 onces, I'd pick by weight and not power since power is already in excess). I decided to go back to school so I sold what I had and never finished the airplane, but I can't wait to hear some flight reports on yours.

BTW - I posted on DOD and 3D batics on this airplane also, so there are threads there too.

Just an FYI, I'll sell you an MVVS 58 for almost $100.00 less than the US distributor. Add to this the fact that this engine will spin 24x10 Mezjlik at 6800 using a Slimline pitts exhaust and you have a strong argument to try one out on your Wild Hare helicopter!

I say order a giles or a extra 260 for the ZDZ 80 and a smaller engine for the edge!

My Feedback: (3)

FreedomFlier - Go for it!!! If you don't like the 28% with the ZDZ-80 you can always put another engine on it. If you don't try it, you'll always wonder just what a spectacle it would have been. Anyway, I'm just telling you that cause I can't wait to hear some flight reports And if you don't like it, no loss, just order up an MVVS 58 or a DA-50.

fredo

Is that 2.3m Composite Arf Extra? If yes I wouldn't mind some comments on this combo 'cos that's exactly what I'm about to get. I have the plane but not the engine yet. I'm thinking of getting ZDZ80 for it but lots of people say it's way too much power. What do you think? Since you already have it, is there anything you wish you made different?

David_Moen

Methinks in this case CA means Columbo-Anderson.

My Feedback: (13)

You are exactly right! I wasn't trying to rain on your parade, I was just providing some 'been there, done that'.

My Extra is a Columbo Anderson...and it flies beautifully. I went with the ZDZ80 because most of the 60-70cc class engines were (then) just as heavy or heavier than the ZDZ.

If you are already proficient with foamies that really jump on command - go for it - prop it with the Pitts muffler on a 24x10 whatever
revs will NOT hurt the engine and if -again IF you are really into 3D -you should love it .
As a suggestion even if the engine is new - buy the Mobil 1 MX2T oil start and stay with 32-1 mix .
we have been running all of our ZDZ's on this and we now let em turn up - my 50 runs in high 7000 range with no scratches on wear spots on piston sleeve/ no carbon ,no bearing loosness.
If you are really new at all of this - too much power can get you in serious trouble .
We have been doing planes for years at 18-20 lbs with this engine (80 )- perfect match.

Thanks Dick... I do enjoy flying foamies, and that is exactly the flavor of T:W and vertical response/control I am shooting for

My biggest concern I have, is the vibration during throttle transition. It really bangs hard.. The frustrating thing is, the balance seems to be perfect on the prop.

I think a heavier/wide-blade prop my mellow it out too . (Mejzlik 26x10?) MSC 26x8? I'm not interested in turning anything over 6500.

If it's too radical, I'll put the ZDZ 60 on it, having the same bolt pattern and all.

Also, anyone running Amsoil with their ZDZ? I mixed up a batch 40:1

rmh

use a stiff prop which has no blade wavering - and will turn 6500-7000 Mejzli26x10 maybe - but let it rev.
these are not electric motors which have max torque/zero rpm
ferget the Amsoil - get some Mobil 1 MX2T run at 32 -1 -
You will likely get carboning with the AMS-I get zero carbon with the Mobil
set timing back a little -to 5mm

How well would a ZDZ 60 perform in the Wildhare Edge 540 28% ? Would this perform unlimited 3D? Thanks for any replied.

I put in a custom BME 60 that keith made up for me . A nother flyer had the same plane with a DA50. Both ran great in all the 3-d movements, but the 60 did clime out faster with the bigger motor and prop. MY came in under 17 # with a lot of C.F parts and lipos. Your ZDZ 60 will fly it great, but, you may want to go with a 23x8 or 24x8 pitch prop to help landing. As far as the zdz 80, sounds good, but I would no be supprised if you take it out after the 2-3 flight.
