Well I wish I could show you a picture but alas I don't know how to put a picture on these replies[&o] The output shaft is 3 1/2" long from the bearing to the tip on this engine. Even though I like my engines on the bulkhead for CG reasons this is a tad rediculous. AV8TOR I know you said it will be ok but just from looking at it and the fact that there is only one crank bearing I do have slight concerns regarding resonance! I know the magneto isn't a damper but a big lump of aluminium is really good at soaking up unwanted vibrations. Oh by the way I have exploded race engines before due to cheap crap dampers! Learned my lesson!

Thanks oltimer2 for the addy's. I'll look them up
