about 60someting Sonexes build until today, about half of them fly behind a
2180cc VW -loef (www.loeff.de) "Jerry Springer" wrote in message link.net... VW let me down twice, would not fly behind one again even if it meant I had to give up flying forever, which I almost did flying behind a VW. When I first got into homebuilt aircraft there were many airplanes using VW's, you do not see many anymore for a reson. YMMV Jerry Don wrote: Many homebuilts on my field with engines mostly Rotax and Jabiru. Two with VW. There were three VW but one had engine failure after takeoff and was destroyed. A visiting aircraft with VW had engine failure on downwind and was destroyed. As previously said, there's no need to use VW now that low cost used Rotax and Jabiru are available.

According to Sonex completions at
http://www.sonex-ltd.com/completions.html only 28% are VW. NTSB reports that Jack Lockamy's VW powered Sonex had 'loss of engine power' after take-off. "... crank/sleeve/hub arrangement cut loose" reported elsewhere. Don "G. A.

![]() As for VW reliability they get a bad reputation because the majority of the ones that quit could be expected to quit. The VW is NOT a simple motor to work on. You have to know it's quirks. Back when I was build'n em for a living I lost a bunch of work to the "guy down the road" because he would do a rebuild for $600 when I charged $800 "for the same thing". I generally had to charge $900, or more, to redo the other guys work - if the customer had any money left 6 months later. Point is there are just too many "experts" that have built a 1/2 dozen or so buggy motors that think they can build a reliable VW aero motor. They generally can't. After you've built a few hundred and lived with them through their life span then you begin to get an idea of what works and what doesn't. Then you get to start all over with that knowledge base and adapt it to the unique demands of pulln' or pushn' a plane. Point is.... Auto rebuilds don't count for squat. Until you have built a couple hundred engines specifically and SUCCESSFULLY for aircraft, you are just flapping your gums, too. So don't disparage the VW just because some are junk. Just like the airframe they power, if properly built and operated within a reasonable envelope they are just as reliable as any powerplant..................in my opinion. Leon McAtee "Puttn' my money where my mouth is" Quickie with 1/2 VW %55 finished Put your money and your ass where your mouth is, but screwing with half a VW is a 'half fast' attempt at flight. For the rest of you contemplating VW power.... check and see if you can find an insurance company that will write hull coverage for you and at what price. What you discover will tell you what VW power is worth to the savvy folks that pay out losses and survive the builder/pilots that don't. Barnyard BOb -- over 50 years of successful flight |

Probably a good idea. If the fellow can't do it right, he shouldn't be flying it. Therein lies the crux of the problem with VW's and other auto-conversions: If LyCons were being built by 100's of backyard mechanics and self-styled experts randomly using a huge base of aftermarket dune buggy parts from God knows where, following do-it-yourself self published tracts, applying racing engine methodologies and being abused by asking two and three times the performance they are capable of, you'd likely see similar incidences of failure. Those who are successful with VW conversions are generally those who put as much effort into building their engines right as LyCon puts into theirs, and then operate the engine within it's abilities.

Until you have built a couple hundred engines specifically and SUCCESSFULLY for aircraft, you are just flapping your gums, too. I believe that - is - essentially what I was saying. But I disagree with the assertion that any prior experience is "worth squat". That prior experience lets one avoid at least some of the basic mistakes. If you or anyone else thinks in some way that I am claiming to be an aero VW expert I'm sorry to have mislead. I am NOT an aero VW expert - yet (my never be). But I do have enough VW experience to see the problems with some of the VW conversions. Many of these problems are basic, known and understood by those with some experience, and lead to unreliability of VW engines, even when installed in ground bound applications. That prior experience allows me to see the limitations of the VW motor. It as a result of that prior experience that I generally recommend to others that they NOT consider the VW as an aircraft powerplant because most often expectations are unrealistically high. To dismiss the motor completely due the the shortcomings of a bunch of amateur converters is short sighted and closed minded. ================= Leon McAtee Atkins trimmed ass leaves less for the 1/2 VW to pull G |

![]() To dismiss the motor completely due the the shortcomings of a bunch of amateur converters is short sighted and closed minded. Leon McAtee Atkins trimmed ass leaves less for the 1/2 VW to pull G +++++++++++++++++++++++++++++++++++++++ OK... For the sake of discussion, consider the amateurs eliminated. Who is left with a reputation of converting and selling hundreds of VW engines that yield PROVEN equal reliability, performance at a significantly lower overall LONG TERM cost than suitably rebuilt aircraft engines... like the 65 hp Continental, for example? Nobody, if you 'axe' me. As far as anyone using 1/2 of a VW goes... They are not even in the business of flying. TURD comes to mind..... Trainee Under Rapid Development. Barnyard BOb - |

I respect all of your opinions but does anyone have actual numbers on
engines (VW, Corvair, Rotax, Lycoming,...)? I'm looking for the number in use, hours flown, number of accidents, etc. "RU ok" wrote in message ...
