Dan,
The belt that was being discussed is the one that has to make the 90
degree transition from the horizontal shaft of the crank to the vertical
shaft of the fan. The belt could be thrown if not tensioned properly or
neglected. This belt is not on the WW conversion.

GEE, ya know when I first made that comment about the "belt" I didn't
identify what it looked like, what it was used for, where it was located,
what its job was BUT it seems that EVERYBODY knew exactly what I was talking
about.
Could it be that EVERYONE who ever "drove" one had the same problem ?. Since
I had the Spider with a 4-speed, all you had to do was over rev it a bit
between gears & the belt was off. IMNSHO it was the twisting of the belt 90
degrees four times for every revolution that was the root cause of the
failures, not the fact that it was bent 90 degrees to connect the crankshaft
pulley to the fan pulley.
I bought one used to save on gas but soon I was back to driving my Corvette
again.
What does drive the alternator on the airborne version ?.

It's still driven by a belt, Lycoming style. I sure wish people would at least look into something before providing an opinion. Information is a great thing to share, but we all know what they say about opinions...

Dan is correct that there is a belt for the alternator, but yes I knew
exactly what you were talking about. What I should have said is there are no
belts (such as fan or redrive etc.) that would cause and engine out in
flight. Incidently, Bernie Pietenpol did use the blower, with that crazy
90deg bend, on his planes.

Great photo, it clears up a nagging question I had. Yes, I do have an0 opinion on just about everything & one of those other things too.
BUT my opinion was based ONLY on my expertise with the land version and0 never questioned the airborne use of the engine.
Wonder why the BMW0 motorcycle (R-60, R-69) engines were not used to power aircraft. I've also had0 an R-60 BMW M/C and with centerline thrust it would seem to have been a0 natural. Do Not Archive KABONG

At the risk of being flamed for non-substantiated0 opinionating (remind me again, is this a discussion forum or sworn0 testimony?)
BMW cycle engines have, in fact, been used0 successfully. Google "BMW aircraft" and get links like this one:

Sometimes in order to more gain information one is required to ask a0 rhetorical question or one in which he has some knowledge. From being a0 detective & teacher I have learned to ask questions where I have some if0 limited knowledge so as to verify the veracity of the answers. In other words I0 don't ask questions where I don't know 25% or so of the answer.
Great info on the BMW. Three problem areas as I see them. Not quite enough0 HP, run in pusher designs only, gear reduction box. Guess that's why I like the0 Jabiru 3300 BUT that's not going to be available for the RV-12.
What is everyone using in form of a pulled/pop rivet to attach the canopy0 on the early Zodiac's 601. Guy here at APV needs some, their identifier0 # & where to order them. Aircraft Spruce does not have them. ZAC says0 three weeks.
