FWIW attached is a copy of the draft report on the flywheel bolt breakage by Anton Lawrence with pictures for those interested in seeing what the problem looks like.

Hope this helps.

Hello guys,

How can we be sure If all this problems were caused by using an improper propeller? so we can rule that out. I´m planning to use a DUC Swirl propeller. I know a few guys that have used them with great success.

Other thoughts were loose prop bolts and 4 inch prop extensions or prop extensions not true

I found my engine shaking at various times (sometimes scary) depending on the power setting and I think it is caused by imbalance when mixture is distributed unevenly L to R because of the lack of a regular symmetrical induction plenum. It is also well worth getting the prop dynamic balanced. Although my prop was carefully static balanced it required 3 g weight to get a dynamic balance and now the prop is a long way from static balance. It seems to mean that we had to compensate for imbalance in the engine itself.
