Engine Box Failure

bullet02

 Greg Foushi & I attended Top Gun 2013 with my PT-17 Stearman entered in Team Scale with Greg as the Pilot & me as the builder. Greg was about midway through the 4th & final flight on Sunday afternoon, May 5th when he sensed that something was wrong & decided to land the Stearman. Just as it stopped rolling the cowl & engine fell in the grass! The prop, hub, cowl & the rest of the Stearman were all undamaged. The following pictures show the process of building a new much stronger engine box.

 The eight Cowl separation pictures were taken by David Hart of Warbird RC Airplane Photography.
