RotecRadialEngineR3600 Crate Arrives

< Project starts with the arrival of the engine

The first thing that had to be done is work out how the drive shaft needs to be engineered to transfer the drive train to the rear of the engine. To do this all the accessories needed to be removed and some serious disassembly was required to access the crank shaft... See the photo showing the rear of the Rotec Radial exposing the rear drive train of the the Rotec radial R3600 >

Acc's removed. Mount plate remved. End of crank exposed.
