Hello again Netters. I just finished reading the Archives search for Crankshaft failures. I entered the dates present to 1990. There were 31 hits on the subject. There was a lot of discussion on failures, but not ONE posting by anyone with a failure that gave any details at all. This is significant. Some members make decisions based on the word of the net. I have flown my type 4 off and on now for over 19 years. My 66 mm crank looks as new. I am moving up to a stock 71 mm crank in what will be a completely different engine. If there are cranks failing I personally really want to know who and why. Tweedy and I are both getting older and would like to continue to do so without having experienced crank failure. So, this post is a call for any one with direct knowledge to sing out.
