Boys and buyers beware.  Could write a book on my Egg experiences.  The botched up construction of those packages was unbelievable.  One arrived in Aust and was dropped. The insurance coy opened the package to see the top plate that held the PSRU to the engine bowed or they thought bent.  I looked at the photo of the “damage” and compared to mine which was not dropped, the package in question was straight!   It was then I realised how ‘dodgy” the packages were.  Flew mine for 60 hours and besides many problems the harmonics annoyed me to the extent that after everything else having been addressed, I removed the package and went rotary.  Do not let any friends or relatives fly behind those packages.  The fact that they are no longer being produced says volumes.  Neil.
