Even the auto-conversion advocates will tell you that everything depends on the quality of the installation. ---------------------------------------------------- Del Rawlins- Remove _kills_spammers_ to reply via email.

Was it a bad engine choice or a bad installation? YMMV, but you appear to share and reflect the pilot-builder's deadly attitude. The devil lurks in the 10,000 details. That is the real issue, was the engine a bad choice or was the installation not done correctly? There is a lot more service history and corporate knowledge on Lycoming and Continental installations than there is for automotive conversions. So a Lycoming or Continental installer has a lot more info to work with, and he is much less likely to come up with a bad installation. I think there is some hope that well engineered, firewall-forward automotive conversion packages may eventually become as reliable as Lycomings or Continentals. But getting the same reliablity from home-brew conversions will be a lot more difficult. We need more guys like Bruce Frank collecting and diseminating information, and all builders need to share info on what works and what doesn't work. -- Kevin Horton RV-8 (finishing kit) Ottawa, Canada http://go.phpwebhosting.com/~khorton/rv8/ e-mail: khorton02(_at_)rogers(_dot_)com |

![]() Dear, dear, dear Bob the accident had noting to do with the kind of engine. So , it is obviously much cheeper to kill your- self behind a non Lycosaurus, isnt it? Obviously, this is too complex for you to see in depth. Like I was telling the other clown of limited capacity and/or experience. There is much more to this than meets the uneducated, untrained and biased eye. Owe who only very seldom agrees with You. And vice-versa. Barnyard BOb -- 50 years of flight |

Barnyard BOb -- 50 years of flight. I have to agree with BOb on this one. You could conclude that the thrust problem was due to the prop pitch being set too fine, which it apparently was. The engine didn't fail. Now, why was the prop pitch set so fine? Two possibilities: the engine wasn't putting out enough power, or the builder simply screwed up with this "non-standard" prop. Why was he using such a "non-standard" prop? He had that prop because of the "non-standard" engine installation. If you stick with a "standard" aviation engine and prop, there is no guarantee they will be problem free, but at least the usual problem areas are well known and you should be able to watch out for them. If you go with a "non-standard" engine and/or prop you don't know what problems to look out for, so you can get bit, as happened in this case. From what I can tell the core engines seem to do OK in the automotive conversions, but it is the other stuff that causes problems - PSRUs, ignition systems, fuel systems, cooling systems, props, etc. But if you have a power loss it doesn't matter whether it was the core engine or some other part that let you down. You are in the trees either way. A local Murphy Rebel flyer had a Subura conversion, but he eventually pulled it out and went with a Lycoming. He had scared himself a few too many times with various failues of his home-brew conversion. ++++++++++++++++++++++++++++++++++++++ Right on and well stated, Kevin. Barnyard BOb -- |

Bob,
You seem to be a grumpy old man "armchair builder". Any pics of planes you have personally built? Or just stories? I'm still building as we speak. Check out my links. And the devil is in the details whether it be a Cont, Lyc or a Soob. I do find it interesting the Honda has designed and is testing a 4 cyl water-cooled aircraft engine for Lycoming to produce. Would that be classed an auto engine by you as well? Semi-literate? Did someone not give you your happy medication today? Some do, others just bitch. - Bart D.

Thanks, Jerry I don't know about the NTSB report but it occured at David Wayne Hooks airport about a year or so ago. The guy didn't stay in the pattern and the engine failed as he was returning to the airport. Crashed into a trailer (and tree) not too far from the airport. I don't know all the details but his engine just stopped with what I later heard were fuel supply problems.
