ZDZ-60 -vs- MVVS/EVO 58
Best Engine?
Which one of these two engines have higher RPM's for the same prop? Best Support? The weights look to be nearly identical, if anything the ZDZ might be a bit lighter. I will put this on a 17.5-18lb Yak. My flight preference is 3D....with no more than a 35% throttle throw to hover the weight of the plane.
I've read a couple of threads that indicate some having problems with the Evolution engines...so I'm leaning now more towards the ZDZ...but interested in what folks have to say.

RE: ZDZ-60 -vs- MVVS/EVO 58
Personally I would move up to a 60 if you want 35% of throttle to hover. A Yak has a big open cowl so a 60 would allow you to swing a slightly larger prop and give you that extra power to match the extra drag.
Engines of choice would probably be a ZDZ 60 or a Brillelli 60. Both great moters and similar weights.

I run a ZDZ 60 for 3 years...Might be old school I don't know but anyones numbers that I have seen on a MVVS 58 with similar exhaust systems don't out do the ZDZ....In 3 years not a minutes trouble and the new owner is just as happy.

I owned a ZDZ 60 and own the 58, Same type Pitts mufflers, the 58 outperforms the 60 ( running a 24/10 from new)but reliability is an open question.
However after 2 yrs my ZDZ needed piston, rings, new bearings and head, all done under warranty so no issues there but I never did get and explanation as to why. ( I think it was the ring pin personally) .

Have you had any issues with the EVO58--you indicate reliability is an open question?

RE: ZDZ-60 -vs- MVVS/EVO 58
I think these engines are pretty equivalent in weight, performance and price from what I can tell. So really its probably who has the best service/reliability? The evo58 is a newer engine design so I would say that it probably has had a few more false starts and that would be expected.
Are the service turnaround times fairly equivalent?
Do the companies return emails as to service or are they impossible to get ahold of on the phone?
Are there any known common failure points?

Hahah It was a play on a certain speach... anyhow... no I have no experience with the 58 motor... but it was related to the ZDZ 60 being an older design. If it ain't broke don't fix it.
Personally I would do some research.. I haven't seen lots of great posts about the 58 yet.. but I have seen some bad ones.
One other thing to note if you start looking at ready to fly weights
58 is going to be right around 5 pounds
ZDZ 60 is going to be 4.75+ pounds
These weights include muffler, ign stand offs etc.
Personally I fly Brillelli motors as of late.. I have own 3 and a 4th one is in the mail due here tomorrow. The Brillelli 60 weighs 4.25 pounds RTF. It's as powerful as those motors and the customer service is outstanding.
If you are set in one of the ones you mentioned it would be ZDZ hands down for me.

The ZDZ60 -on a MenzS 24x10 -and we have run various ones --turns low 6000 to 6400 -depending on exhaust setup My original one from a few years back - still is in use by present owner and runs like new.
The MVVS fom all the figures posted is in the same ball park
I ran mine in a Dalotel -18 lbs and a 202 -both scratch built - both 1500+ squares both 18 + lbs
both really good power matches to the airframes -here at 4350 ft elevation.
If you prop either engine correctly (let em spin) --your Yak should be a good toy

Never heard of Brillelli...who is the US distributor or their website where you can look at these?

http://www.brillelli.com/brillelli_010.htm Is that particular engine
I would highly recommend a search of the forums for Brillelli. You will find lots of great reports.

RE: ZDZ-60 -vs- MVVS/EVO 58
I have a MVVS 58 I bought just before the change in name and vendors. I have had good luck with it so far. It does have good power and I use a Mejslik 24/12 on it as it tached above mfg. recommendations using a 24/10. Although I have had good luck with it I don't know if there is any difference with the Evoloution 58. MY experence with the Evolution 100 was not good and I replaced it with an OS 120.

The Brillelli has a side mounted carb, while both the ZDZ and the MVVS/Evolution have rear mounted carbs.
This may affect your decision. (Although possibly not in a Yak, there should be room for both.)

Well my first 58 ate the piston ring twice in under 6 gallons of fuel, then was replaced and the brand new 58 won't even start and has been sent in to horizon twice now for this problem.
2 1/2 months and I still don't have a running engine.

On the website it shows some "worst case" measurements. Anything more precise? Like the width--does it include velocity stack? I need to make sure this thing will fit.

I dont believe it includes the v-stack
you can email [email protected] and he will be happy to answer all your questions.. very nice guy.
They are in the middle of redoing their site so its not quite done.

Ok thanks..I fired off an email to him.
Ok, lets say it fits but with the velocity stack....can you take that off without affecting performance?
