Zu-DSR's Engine problems (was ZU-DSR first engen out)

[Wingless Nut]

OK Leppie my ou tjom! I take your point. The problem as I see it is getting a reliable PSRU fitted to the BMW and possibly also the Smart, without the use of flexing and constantly destressing adapter plates. Does Cytech make up the complete unit with engine and gearbox coupled for that price? Their contact details please sir. By the way, you're slowly appearing to be more of a "kastrol" now.

Interesting how a post on one guys engine out leads to this. That Verner in the pic on the back or AR's Aquilla is now safely in my possesion in my brothers garage in Pta. I'll be returning to SA in April, and will fit it to my Safari. Listen out for the trike that sounds like a bumble bee rather than a mosquito in the sky over the highveld soon.

I have been in the USA for just on 2 years, and have looked at all sorts of engine options. Specifically wanted to move on to 4 stroke. Here, Rotax also dominates the UL scene, but there are a lot of other engines around. Verner does not do great here, but there are a number of them around. Everyone I could get hold of spoke highly of it, maybe not as smooth as the 912, but powerful and reliable.

I first spoke to the local agent about these engines more than a year ago, he then told me that he was getting it fitted to a trike soon. I was in SA for a short visit late in last year, and called him to find out how the test was going. I don't know all the poletics involved, but the engine was back in his garage, never having flown. Now, I'm not interested in all that shite, and gladly relieved him of said engine, and for what I believe was a very reasonable price, I might add.

He is wanting to give up the agency for this engine. It will be good if someone takes it over, I seriously believe this engine has potential. Not to take market share from any other brand, but genuine healthy competition has always been good for everyone.

How will I get this supported? The manufacturer in Czech is one option, and I can always deal with the agents here in the USA. The world is a very small place today, and getting things shipped from anywhere on the globe is no problem.

How good and reliable the Verner is, I do not know at this time, but I have high hopes for it. I will do an article on the installation as soon as I'm back in the land of Windhoek Lager and Biltong.

There are a few BMW boxers flying here as well, very powerful, but somewhat heavy, but a very good choice I would think. There are a number of reduction drives available from Poland, Czech and Germany. I have seen quite a lot of discussion on problems with the wiring harnesses and Engine Management Computers. Don't know much about these so I stay well away. One company that have them for sale, and seem to have all the electronics sorted out is Take-off in Germany, but then it does not come cheap.

A few Smart (Mercedes 650cc) engines in kit planes, but don't know of any on trikes. May be a good option to investigate.

Hundreds of guys flying with Suzuki 1000, 3 cylinders here. Reports are that they are reliable and trouble free. Somewhat heavier than 582, same horses, uses half the fuel and costs way less. I'm bringing one of these home, and intend to fit it onto something, we'll see. Will report on that as well.

I will never understand how some people always find the need to bad mouth other products. I like freedom choice and variety, it makes things interesting. And, it's like our notorious minibus Taxis; there's room for everyone.

Can't help to wonder if this is the same motor that Hennie from Kroonstad Had use on the Raven he build a while back.

I know he is inporting the motors himself.

But back to the vw motor, Arno phoned me this morning to inform me that it was the crank that snapped. The motor have been re done compleatly with new crank, mains, biggends, Line drilled ........ R 7700.00 + vat and he would asembel compleatly, start and let it run today. I'm even sending him a disc with the data for the onbord computer to check out for me.

Can't wait to recive it back. :D

Well said Pumba
Hats off to those who chart the way with the unproven. Competition is what we need. I would love to have a choice of reliable engines rather than just one. And then there is the cost of this aparently reliable engine. They have the market share so can basically charge what they want.
Keep us posted

Bennie ek is seker Hennie het n Zuzuki gebruik.

[GR8-DAD]

Bennie, R7700 is 'n bargain, steeds bloedgeld, maar 'n bargain. Ek sou die ou by wie jy die aerie gekoop het vir 'n bydrae gevra het

Dad ek sal moet, anders moet ek die vliegtuig verkoop om die motor te kan terug kry.

NS: Ek wonder wat die selfde werk aan 'n Rotex my uit die sak sou jaag.

Ek het al voorheen gehoor van Hennie in Kroonstad. Het jy vir my kontak details? Ek vrek om te hoor van ander Suzukis in SA. pm my met details as jy kan.

Goed om te hoop die vliegtuig is amper reg Bennie. Nou kry hom in die lug ek is seker jy en Riaan kan 'n cross country Ladysmith doen.

There is a very interesting thread on Avcom by "Willie" regarding broken cranks on engines.

Just an extra note to the heavy engines, re Smart and Suzuki - Having a heavier engine is sometimes NOT a factor as if you use half the fuel or even 1/3 you will save weight there. Not to mention the Smart IS TURBO CHARGED.

45l for 3 hour endurance = 33kg
15 for 3 hour endurance = 11kg, so for take off perf we have saved 20kg
so we must surely work on NET or take off weight, not engine weight. Lets says engine is 30kg heavier then the diff is only 10kg and as it's Turbo charged won't be aproblem in Gauteng, see next figures


It always kinda irritates me how we refer to the 582 and 503's as being 64 and 50hp motors, in Gauteng...

Assuming a loss of 4% / 1000ft, some manus recommend 4.5 on their 2 strokes - others 3.5, I've avg'd it.

Given a day of 15 degrees in Gauteng your 582 has less than 50hp (35kw) and a day of 30C dropping to about 43hp, so not ripping off the 582 as it has AMPLE power up here but it shows why ppl at the coast are more than happy to have a 503 without all the cooling stuff / weight. This shows you just how LITTLE power we have with the 3 H's Hot, High, Humid - My 582 at 45hp NO WAY

Plus it shows why having a turbo charged motor of 50hp would be sufficient for trikes (it's ample on my 582) as it remains pretty consistent up to about 12000'. So dont get saddened by 50 turbo charged horses, and I haven't even mentioned Torque curves or values. To my knowledge tho the Smart petrol has around 60hp not kw - could be wrong? To quote Verner engines or was it Hirth? "Horse power sells engines but Torque gets you moving".

Many ppl say they've flown 912 trikes and can't feel much of a dif vs 582 well at 30 C you'd only have about 53hp and then we could compare takeoff weight.

If anyone feels my calcs are wrong please let me know so I can correct them. I calc'd using the DA and base of 5300ft @ 4% per 1000ft.

My point to this post is that before shooting down engines with high / low power or high / low weights look at all factors and you'll be surprised how many options we have.
