Default Aeroworks 33% Ultimate with ZDZ80?

Curious to opinions on setting up an Aeroworks 33% Ultimate with a ZDZ 80 or comparable, DA-75 maybe if they ever come out.

Thanks.

If you already have thew ZDZ I don't see why not. If you don't, why not spend almost the same amount of money and get a BME 110 that weighs about the same but has a gawdawful lot more power? Provides more options for later aircraft.

Well maybe - but $900 vs $1400 is not an "almost".
There are now a number of single 80's on the market .
The ZDZ80J
The 3W "80"
The EVO 80
Perhaps a DA75.
Pricewise - it is possible to purchase a good "80" ($700/800+)AND a bargain priced ARF --for about the same money as a 100 twin
These range from $1100 bucks plus two mufflers - so $1200 is about rock bottom.The 110 is 1400 bucks inc mufflers !!
Powerwise -as much as the 100's are bragged on -is not much more -if any -than a well setup 80 single with good quiet exhaust.
The new 80's are also very smooth running -easy to mount and if a quiet exhaust system is desired -much less expensive and easier to fit to most of the airframes. Add to that simpler ignitions - less cowl room required to properly cool and the case for a modern 80 looks very good compared to any 100.
Especially if a budget is an issue .
Believe it or not - many fliers do not want to "move up".
a plane kept under 100" span and around 20 lbs is extremely attractive to guys with a family van/ car SUV etc., for hauling the model to the field.
I see a solid future for the single 80's -
The economics of it alone, are quite attractive.

Dick-- Agree 100%. The only point worth mentioning in defense of the 110 would be that it would fit in an Ultimate cowl much better than an inverted 80. Personally, I'll take the 80 and the extra $500 m/l and let those cooling fins hang out in the breeze.

You forgot the ZDZ-80RV dick.
People are throwing these engines away literally at RCU waiting for the new motors and not realizing that this motor still kicks *****.

Dick,

Having a 40% plane for quite a few years I could not agree with you more. That plane takes more effort and planning to take to the field vise some of my 50cc planes along wth its usually the only one that I can take at the time if i take the 40%. I have a better auidence to sell my smalller stuff to if that days comes along. The 40% has a smaller auidence of buyers if that day comes alone. I suppose a flyer has to look at what are his long term goals......

I have a 3W- 85 twin new in the box. Do you think its big enough for the 33% Ultimate? I don't plan on doing any 3D flying.

The rest of your quote I will agree, but I can not really agree with that. A well set-up 80 and a well set up 110 are with in oz's of each other, (some 80's more than a 110) and I have a dollar in my pocket that say's I know which one will produce more power and be just as smoooth too.

I can't get my 80 to pull much over 7300 on a Mejzlic 26x10 -so I guess I will back off on that one .

No one has mentioned that the plane will be real tail heavy on a stock 80 setup. I should know since i have the setup with a zdz 80. All the batteries on the motor box, lighted tail wheel and stab tube. Still need a good amount of lead in the front of the cowl. Motor shoved as far forward as possible. Mezlick prop and Alum spinner for more weight. Total weight with a Power expander onboard....26lbs 7oz on a digital postal scale. If i could do it again i would install a DA or 3W twin just for the pure usable nose weight.

Smokey - I put my servos up front and use cables and pushrods for some setups - sure more work but it really keeps things in balance
As for performance -patience and a little oil goes a long way -----------

Default RE: Aeroworks 33% Ultimate with ZDZ80?

At 26 pounds plus, any 80, single or twin, super exhaust or stock, will be working pretty hard most of the time for high performance aerobatics. 26 pounds and an 80 for 3D with a bipe is almost out of the question. It'll fly, but I wouldn't ever be as happy with it as I could be.

I admit I was not aware that the price difference between the two engines was so large, but power wise the 110 will smoke any of the 80's any time or place. Now if you want to spend the extra money on trick exhaust for the 80, add some nice quiet cans and so on, where do you end up price wise?

If the 33% Aeroworks Ultimate comes in at 26 pounds, personally I wouldn't think of considering a 75 or 80. Not if I wanted the performance the plane could easily deliver. 100cc's would be the smallest I would look at. Baffles are easy.

For those that would want to stay in the smaller size range and not move up, a 75 or 80 makes sense. But if there is a chance for growth, the 80 becomes a waste of capital when the purchase of a larger engine takes place.

Interesting - one mans' waste is another mans' bargain.
Some are "movin on up"
Others are "movin on out"
Sounds like the Jeffersons-----

D.H., what are you running for exhaust on your 80 , tuned? I don't think most of the people here know that you set up racing engines.

BTW, you'll note I was careful not say waste of an engine, only capital. Kinda like buying a 4 channel radio when you should have bought a 6 channel.

At the present the 80 J is in a EDGE by H9 - 22+lbs -so I am running a simple exhaust setup.
This is a 5" long, large ID header with a large JMB can.- The can acts sorta like an extractor only -which is then well muffled . It is a great setup for any two stroke as it can scavange a little and is very quiet.
For max power - a AMT tuned pipe on 11" long header. This takes up about 30" of room overall in/under bottom of model -so tho it really boosts the power it is not for anyone who can't do some work on the model .
It is not a racing setup -
The resultant power band is stronger , brighter in response from idle on up.
This type setup -if badly mismatched to prop will result in extremely poor running engine .
Same thing, adding "racing" equippment -incorrectly to any kind of engine.
I have used model engines up to 160cc in larger planes
Although the big models are great for some people - I really got tired of trying to lug em up and down stairs- and I refuse to turn my garage into a hanger - so a model which is close to 20 lbs and under 100' is all I want to handle.
" Movin up" was frankly not a my cup of tea.
At the moment I have 5 ,26cc-80cc models in gas and a shi- load of electrics
The gas engines 3 have full tuned exhausts a Roto 25, a 26 Evolution and a ZDZ50 .plus a 40 ZDZ RE and the 80J, both on the short muffler JMB setups.
Throttle response and power is instant on all of them and all are very quiet easy to operate setups
I have run racing setups -setup for just top end power - they are a pain in the butt. But-they went really quick!

Smokey had a really good point. I Put an older heavier 7.5 lb 3W 100 in mine and with my servos in the rear I had to move all batts in to the motor box to balance. I live in colorado and talk to rocco up at aerowork frequently. when I got mine and we discussed this he mentioned that this plane was designed quite a number of years ago and the production of the plane was very slow. The newer lighter engines did not exist then and aeroworks favored 3W at the time. The plane was designed with it in mind and frequently still came out tail heavy. With a lighter small engine in the nose you are likely to end up adding a LOT of weight up front to get your CG. Kind of defeats the purpose on that light small engine. I do not now about lower altitudes but up at a mile high this plane needs 100cc power. Two wings and flying wires produce lots of drag on the vertical.

My scratched Ultimate has 80inch span, 2000sq/in, and 24/25 lbs. ZDZ 80rv with Bisson Pitts. It will pull out of a hover just fine. I like flying it with the Biela 26-10, very good at 3D

Actually, watching the video of the Aeroworks 33% Ultimate, http://www.aero-works.net/store/detail.aspx?ID=82 my pullout is almost as good, however I am at sea level.

One of the guys I fly with has a WM 33% ultimate with a 3w 75 in it. I believe it's AUW is around the 24 pound mark and it flies very well. 3D ins't a problem at all. The one downside is the verticle pullout from a hover is a little slow, but punch the throttle and some down elevator and it flies off without a drama.
