ORIGINAL: MTK
Todd Syssa discussed with Ed and I his design philosophy as to why he chose certain materials (a steel rod, for example, rather than aluminum...or needle bearings on both ends of the rod....or, quadruple sealed bearings up front, etc etc), and I must say that sold me. After flying the engine in an overweight and oversized Pattern model, performence sold me again.

Thank you for the info about the internals, I wouldn't go with a DL anyway..but wanted to know if there
was any performance difference...
How did you fair with the lightened zdz40cc??
